  Objective: This qualitative study aimed to investigate how patients with severe dental anxiety perceived cognitive behavioral therapy (CBT) delivered by interdisciplinary teams consisting of psychologists and dental personnel. Material and methods: Twelve individual semi-structured interviews were conducted at the Oral Health Center of Expertise in Eastern Norway, using an exploratory qualitative design. The analysis was guided by Braun and Clarke’s thematic analysis. Self-determination theory (SDT) was applied as the theoretical and analytical framework. Results: The qualitative analysis identified five themes shaping patients’ experiences with CBT and progress in managing dental treatment: Establishing positive relationships with the psychologist and dental personnel, Experiencing enhanced competence in managing one’s anxiety, Discovering the opportunity to use one’s own capacities, Identifying factors nurturing plans for future dental visits, and Experiencing additional effects on quality of life. These results underscore the importance of autonomy-supportive treatment that fulfills patients’ basic psychological needs (BPNs) for autonomy, competence, and relatedness, thereby fostering more autonomous motivation and desired behavioral changes. Conclusions: The findings indicate that CBT provided by interdisciplinary teams may benefit from adopting SDT as a framework, integrating autonomy-supportive principles to fulfill patients’ BPNs. This approach may enhance CBT’s patient-centered effectiveness and potentially improve patients’ quality of life.

  Objective: To map dental health service utilization (DSU) and associated factors among older adults receiving home care services (HCS) in south-eastern Norway, using Andersen’s model. Materials and methods: In this cross-sectional study of older adults receiving HCS aged ≥ 65 years, data on oral health practices, general health, and predisposing, enabling, and need-based factors were collected via interviewer-administered questionnaire. Results: Of 116 participants (mean age 83, 53.6% female), 67.2% reported annual DSU, while 24.1% used dental health services only for acute problems. Although 95.6% were entitled to free dental care in the public dental service (PDS), 66 were aware of this, and 56.5% made use of their rights. Awareness of entitlements was associated with more frequent PDS use. A higher self-reported number of teeth and using private dental services were also linked to higher DSU. Conclusions: The present study showed underutilization of dental health services among older adults receiving HCS and unawareness of entitlement of their rights in PDS. However, higher self-reported number of teeth and use of private dental services were linked to more frequent DSU. To address underuse, the PDS should improve awareness of entitlements, enhance information delivery, and further investigate reasons for non-utilization.

  Occupational exposure to airborne particles and bioaerosols in dental clinics is a potential hazard to dental health workers. Current studies on airborne particles and bioaerosols in dental clinics are limited and methodologically diverse, leaving gaps in the understanding of airborne particles in real-life dental settings. The aim of the study was to investigate the size, concentration, and composition of particles produced during dental procedures, and determine the exposure levels of dental personnel to respirable particles and bioaerosols in dental clinical environments with different characteristics. The study included two conventional dentist offices and one specialty clinic. The number concentration and size distribution of particles released during different dental procedures were monitored in real-time in dental procedure rooms. Personal samplers were used in parallel to collect the respirable and inhalable particle fractions. Total bacterial and total fungal DNA concentrations were quantified in the inhalable particle fraction by droplet digital polymerase chain reaction. Particle morphology and chemical composition were analyzed using scanning electron microscopy. The highest geometric mean value of the respirable particle mass concentration (0.06 mg/m3) was below the Norwegian occupational exposure limit for respirable dust of 5 mg/m3. Real-time sampling indicated that particle number concentrations were elevated during working hours in two clinics, with peak levels observed in one clinic coinciding with air polishing activities. The results also showed significant variations in bacterial and fungal DNA concentration levels (P < 0.0001). Many collected particles originated from powders used in dental treatments. Despite low respirable particle mass concentrations, increased levels of ultrafine particles during dental procedures highlight potential health risks to dental professionals. These findings also underscore the importance of advanced ventilation and safety measures to mitigate occupational exposure in dental environments.

  Background An increasing number of older adults receive home healthcare in their homes, some of whom lose their capacity and ability to take care of their own health, including oral health. Poor oral health may have serious consequences that can lead to poor nutrition, diseases, isolation, and even death. There is an urgent need to involve users in developing targeted interventions to ensure that eligible older adults exercise their right to receive appropriate dental care. The purpose of the study was to explore what user groups emphasised in co-creating a targeted dental care intervention for older adults receiving home healthcare. Methods In this study, an exploratory design with an inductive and interpretive approach was employed. In two six-hour workshops, eleven participants representing three older adults, one next of kin, two nurses, and five dental care providers exchanged and discussed their perspectives on dental care as part of a co-creation process. Data were collected from group and plenary discussions during the workshops and were analysed using reflexive thematic analysis. Results The different user groups conveyed confusing and contradictory understandings and interpretations of the dental healthcare landscape. This uncertainty resulted in missed information regarding dental care, leading to situations where they do not always seek dental healthcare services until an acute issue arises. A blurred perception of older adults’ needs for support, combined with shortcomings in collaboration, communication, and the exchange of digital information systems, has led to a lack of knowledge about one another and inadequate dental healthcare for this vulnerable group. The various user groups suggested different solutions; however, several key issues emerged as urgent to address. There is a need to build and integrate systems into home healthcare’s digital administrative and health record systems to support the clarification and identification of eligible patients, as well as to develop a digital coordination and communication system to connect the two levels of service. Conclusions Unpacking the perspectives of the different user groups uncovered that an intervention must take into account the views of all groups. Understanding and incorporating the perceptions of all the different user groups were crucial for developing an intervention that enables a preventive and collaborative dental care approach.

  Background There is little knowledge about home care services personnel competencies and beliefs concerning oral healthcare for home-dwelling, dependent older adults. This study aims to map oral healthcare beliefs among home care services personnel, and have the following question: How do the education level, years of work experience and training in oral health have impact on home care services personnel oral healthcare beliefs? Methods A cross-sectional study among home care services personnel working with older people receiving home care services was conducted across four municipalities in south-eastern Norway. The questionnaire consisted of background information (gender, education level, years of work experience, training in oral healthcare, employment status) and the nursing Dental Coping Beliefs scale. Ethics approval for this study was obtained from the Norwegian Centre for Research Data. Results Two hundred and sixty-two homecare services personnel responded to the questionnaire, 16.5% males and 83.5% females; 40.5% had had training in oral healthcare. Home care services personnel believed that gum diseases and cavities can be prevented by dental flossing (61.4%) and toothbrushing (98.4%). 59% disagreed that preventing sickness and medicines from destroying teeth is impossible. However, the majority of the home care services personnel were uncertain about how oral mucosal disorders can be treated. Having more than three years of higher education was positively associated with being in higher quartiles of oral healthcare beliefs, and external locus of control, and having training in oral healthcare was positively associated with being in the lower quartiles of internal locus of control and self-efficacy dimensions. Males were more likely to be in the lower quartile of oral healthcare beliefs, which wasn’t positive. Conclusion In the population studied, the home care services personnel beliefs about oral healthcare improved with an increasing level of education and having had training in oral healthcare. This suggests that home care services personnel need more education and training in oral healthcare.

  Background Providing dental services to dependent older adults might be challenging because of physical and cognitive decline. The present study aimed to explore current practices, knowledge, and experienced challenges related to the treatment of older adults in home health care services (HHCS) among dentists and dental hygienists in Norway. Methods An electronic questionnaire survey was distributed to Norwegian dentists and dental hygienists, inquiring about background characteristics, current practices, self-perceived knowledge, and challenges when providing oral health care for older HHCS patients. Results Four hundred and sixty-six dentists and 244 dental hygienists treating older HHCS patients responded to the survey. The majority were female (n=620; 87.3%) and worked in the public dental service (PDS) (n=639; 90%). When older HHCS adults attended the dental practice, the treatments provided were most frequently aimed at relieving acute oral problems, although dental hygienists reported to focus on improving oral health more often than dentists. Dentists reported to have more self-perceived knowledge than dental hygienists regarding patients with complex treatment needs, cognitive or physical impairment. Exploratory Factor Analysis (EFA) was carried out on the 16 items related to challenges, three factors were extracted and Structural Equation Models (SEMs) were performed. Challenges related to dental care for older HHCS adults were related to time, practical organization and communication. Variation within these categories was associated with sex, graduation year and country, as well as time used per patient and work sector, but not with professional status. Conclusions The results indicate that dental care for older HHCS patients is time-demanding and more often aimed at relieving symptoms than improving oral health. A substantial proportion of dentists and dental hygienists in Norway lack confidence when providing dental care for frail elderly.

  Aim To examine factors that affect the performance of oral health care (OHC) for older people receiving nursing care at home. Background Oral health is often neglected by health care providers caring for older people. Research shows that health care providers' provision of OHC may be influenced by various factors (barriers and facilitators). When this research was conducted, health care providers from home healthcare services (HHCS) and nursing homes were grouped together despite setting differences; therefore, this study focuses on the performance of OHC by home health care providers (HHCPs) as a single group. Design Explorative design with a qualitative approach. Methods The managers of four HHCS units recruited 17 HHCPs to participate in focus group interviews. One interview was conducted per unit, and there were four to five participants in each interview. The analysis of interviews was based on theoretical thematic analysis and the PRECEDE constructs in the PRECEDE–PROCEED model. Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines were used in reporting this study. Findings The analysis resulted in two themes with predisposing factors (HHCPs' professional responsibilities, older people's attitude), five themes with enabling factors (knowledge and skills, older people/carer trust, available time, available equipment and collaboration with public dental service (PDS)), and two themes with reinforcing factors (routines and OHC focus on the workplace) that affect the provision of OHC. The factors were categorised as individual, organisational and collaboration factors. Conclusions In addition to individual factors found in previous studies, factors related to the organisation of services and communication between HHCPs and PDS seem to affect HHCPs' provision of OHC for adults receiving HHCS. Implications for Practice This study provides in-depth knowledge that can contribute to increasing HHCPs' provision of OHC and thereby prevent oral and dental disease among older people receiving HHCS.

  Objective To map the literature on subjective and objective oral health indicators and oral health-related quality of life (OHRQoL) in older adults receiving home health care services (HHCS). Background The proportion of older adults in need of HHCS will increase in the coming years. Previous studies indicate that frail and dependent older adults are at increased risk for oral diseases, due to challenges with daily oral hygiene and regular access to dental services. Materials and methods Four databases were searched in November 2020 for relevant literature. Search terms included a comprehensive list of terms for adults 65 years or older receiving HHCS, clinical and subjective oral health indicators, and OHRQoL. The literature was reviewed based on inclusion and exclusion criteria. Results Of the 3114 sources identified, 18 were included. Data on oral diseases and symptoms among older adults receiving HHCS were limited and heterogeneous. Overall, older adults often lacked some of their natural teeth and often had removable dentures that needed repair. In addition, plaque, caries, xerostomia, and chewing and swallowing problems were common among the population group. Data on OHRQoL were scarce and indicated a positive association with a higher number of present teeth, while decayed teeth, root remnants, and dry mouth had substantial negative impacts on the daily activities of older adults receiving HHCS. Conclusion This scoping review show that older adults above 65 years receiving HHCS generally have poor oral health status and that there is a knowledge gap regarding their OHRQoL.

  Objectives The aim of this study was to compare periapical status transitions in teeth after post placement compared with other post-endodontic treatments in root-filled teeth. Material and methods This retrospective longitudinal radiographic study included radiographs of 284 patients with root filled and restored teeth with composite fillings (Endo-fill group, n = 100), crown or fixed prosthesis (Endo-crown group, n = 82) or post and core restorations (Endo-post group, n = 102). All post and core restorations were made of gold alloy. The radiographs taken at the end of endodontic treatment, at the end of post-endodontic treatment and at least 8 months after post-endodontic treatment were evaluated. Post-operative periapical status was assessed according to the periapical index (PAI) and all teeth included in the study had no apical periodontitis preoperatively. Multi-state Markov analysis was used to assess periapical status transitions among the treatment groups. Results Of 284 root-filled teeth without apical periodontitis at baseline, 7.7% developed clear apical pathology within a minimum of 8 months observational period. In the Endo-post group 11 (10.78%) teeth transited from Healthy (PAI 1) to Disease (PAI 2-4) state compared with eight (9.75%) in the Endo-crown group and four (4%) in the Endo-fill group. The transition probabilities from Healthy (PAI 1) to Mild diseased (PAI 2) were 17.5% in the Endo-post group, 13.1% in the Endo-crown group and 5.3% in the Endo-fill group. Multivariate analysis showed that teeth in the Endo-fill group had 60% lower hazard to transit from Healthy (PAI 1) to Mild diseased (PAI 2) state [HR 0.40; 95% CI 0.12, 0.94]. A period exceeding 8 months between the end of the endodontic treatment and prosthetic treatment significantly increased the hazard of disease progression by three times compared with a period of ≤8 months [HR 3.16; 95% CI 1.06, 9.42]. Conclusions Teeth without radiographic lesions at baseline and restored with posts had higher hazard to transit from healthy to diseased periapical status compared with teeth restored with composite restorations. Controlled clinical trials with longer follow-up periods are needed to validate these findings.

  Background Stainless-steel crowns (SSCs) are recommended for restorative treatment of young teeth severely affected by caries, fractures or dental developmental disorders (DDDs). However, despite recommendations and clinical evidence, SSCs are not widely used by general dentists, who favour extraction and more conventional restorations. The present study aimed to investigate the views of and use of SSCs among Norwegian and Finnish dentists. Methods The present study was a cross-sectional survey among Norwegian and Finnish dentists. An electronic questionnaire was sent to Norwegian and Finnish dentists asking whether they used SSCs and on which indications. In addition, the questionnaire assessed reasons for non-use and dentists’ perceptions regarding advantages and challenges in the use of SSCs, as well as the need for additional training. Distributions of background characteristics, use of and views on SSCs were calculated, and statistical significance of the associations between respondents’ background and their answers were evaluated. Results Of the 574 Norwegian and 765 Finnish respondents, only 12.0% and 12.9% reported to use SSCs, respectively. The most frequently reported barrier reported by those who did not use SSCs was lack of practical training. The most frequent challenge reported by those using SSCs was difficulties in crown adjustment followed by aesthetic issues, and the most frequently reported advantage was that SSCs maintain the function and occlusion. The majority of respondents reported a need for more information and practical training in the use of SSCs, with hands-on course as their most frequently preferred education type. Conclusion Although the value of SSCs for restoring young molars is recognized by Norwegian and Finnish dentists, SSCs are rarely used by general dentists. The majority of the respondents reported lack of training and materials and was interested in receiving more information and education.

  Background - The SARS-CoV-2 pandemic put a pressure on all healthcare professionals and has affected the delivery of health care services globally. There is a need to understand the impact on different health care professionals in different countries. The aim of the present study was to explore the psychological impact of the pandemic among dental staff in Norway in relation to background characteristics, work situation and preparedness of the service.<p> <p>Methods - A structured questionnaire sent electronically to dentists, dental hygienists and dental assistants inquired information about the lockdown period in Norway (13 March-17 April 2020). Distributions of background characteristics, perceptions of preparedness and psychological impact were calculated. Exploratory factor analysis was performed, and Structural Equation Models (SEMs) were used to compare psychological impact between dental professionals treating patients versus not during lockdown.<p> <p>Results - Among the 1237 respondents, 58.8% worked clinically with patients. The majority were concerned of becoming infected (71.9%), of infecting others (85.4%) and/or of their family becoming infected (76.9%). Respondents who treated patients felt significantly more insecure about whether having become infected or not. The minority felt discriminated (6.7%), worried about death (11.7%), felt that life was threatening (9.8%) or felt loss of control of their lives (8.9%). More than 80% agreed that their workplace handled the situation well. Four factors were retrieved from the factor analysis. SEMs showed that gender and work experience had a significant effect on the factors Instability, Infection and Concerns. Respondents with work experience ≥10 years were less likely to express fear about Instability and Infection. Personnel reporting that their workplace had adequate equipment were also less concerned, however having adequate equipment did not reduce the factor Loss of control.<p> <p>Conclusion - The present study showed a considerable psychological impact of the COVID-19 pandemic on dental personnel in Norway regardless of working clinically with patients or not. However, working with patients increased the insecurity about own infection status and of infecting people close to them. A safe working environment and adequate infection control measures are associated with less fear of infection and feeling of instability.

  Objective The project aims to evaluate whether inhalation of particles released upon grinding of dental composites may pose a health hazard to dentists. The main objective of the study was to characterize the dust from polymer-based dental composites ground with different grain sized burs and investigate particle uptake and the potential cytotoxic effects in human bronchial cells. Methods Polymerized blocks of two dental composites, Filtek™ Z250 and Filtek™ Z500 from 3M™ ESPE, were ground with super coarse (black) and fine (red) burs inside a glass chamber. Ultrafine airborne dust concentration and particle size distribution was measured real-time during grinding with a scanning mobility particle sizer (SMPS). Filter-collected airborne particles were characterized with dynamic light scattering (DLS) and scanning electron microscopy (SEM). Human bronchial epithelial cells (HBEC-3KT) were exposed to the dusts in dose-effect experiments. Toxicity was measured with lactate dehydrogenase (LDH) assay and cell counting kit-8 (CCK8). Cellular uptake was observed with transmission electron microscopy (TEM). Results Airborne ultrafine particles showed that most particles were in the size range 15−35 nm (SMPS). SEM analysis proved that more than 80% of the particles have a minimum Feret diameter less than 1 μm. In solution (DLS), the particles have larger diameters and tend to agglomerate. Cell toxicity (LDH, CCK8) is shown after 48 h and 72 h exposure times and at the highest doses. TEM showed presence of the particles within the cell cytoplasm.

The Norwegian Centre for Research Data (NSD) approved the study.<p> <p><i>Results</i> - Thirty-five percent of the dentists and 10% of the dental hygienists had treated five or more drug users per month (p <  0.05). The majority of dentists and dental hygienists used more time for examination and treatment of drug users compared to other patient groups. Over 70% of dental clinicians considered drug users as demanding patients due to fear, missing appointments, and poor compliance with oral hygiene advice. Multivariable logistic regression analyses showed that attitudes and experiences with dental treatment of drug users were significantly associated with background characteristics of professionals. The overall perception was that drug users often had higher expectations of dental treatment than what could be defined as necessary care and provided by the PDS. One-third of dental professionals reported that they were satisfied with the collaboration they had with RIs. Most of the respondents agreed that personnel from RIs could positively influence interprofessional collaboration by having sufficient knowledge of drug users statutory rights to free of charge dental treatment, as well as by close follow-up and motivation of patients before dental treatment.<p> <p><i>Conclusions</i> - Dental professionals perceived the management of drug users as demanding due to dental fear, difficulties in coping with appointments, poor compliance to preventive measures, and disagreement between dental treatment defined as necessary and drug users’ expectations. Attitudes and experiences related to dental treatment of drug users were significantly associated with background characteristics of clinicians. Organizational barriers regarding leadership, accessibility, and collaborative routines, as well as lack of interprofessional communication, suggest current models of health care delivery to drug users need reviewing.

  We aimed to investigate the management of urgent dental care, the perception of risk and workplace preparedness among dental staff in Norway during the COVID-19 pandemic. An electronic questionnaire regarding the strictest confinement period in Norway (13 March–17 April 2020) was distributed to dental staff. Among the 1237 respondents, 727 (59%) treated patients, of whom 170 (14%) worked in clinics designated to treat patients suspected or confirmed to have COVID-19. Out of them 88% (143) received training and 64% (103) simulation in additional infection prevention procedures, while 27 (24%) respondents reported deviation. In total, 1051 (85%) respondents perceived that dental staff had a high risk of being infected, 1039 (84%) that their workplace handled the current situation well, 767 (62%) that their workplace had adequate infection control equipment and 507 (41%) agreed that their workplace is well equipped to handle an escalation. Before an appointment, 1182 (96%) respondents always/often inquired per phone information if a patient experienced symptoms of COVID-19, and 1104 (89%) asked about a history of travel to affected areas. Twice as many patients on average per week were treated by phone than in a clinic. A lower proportion of dental staff in high incidence counties applied additional infection prevention measures compared to low and medium incidence counties. To conclude, urgent dental health care was managed relatively well in Norway. Additional training of the dental staff in adequate infection prevention and step-by-step procedures may be needed. These results may be used to improve the dental health service’s response to future outbreaks.

  Abstract Dental health care professionals have the opportunity to play a key role in tobacco prevention and cessation among adolescents. Snus use has increased in Norway, especially in the age group 16–24, whereas there has been a decline in smoking. This study investigated attitudes and activities related to snus prevention among dental health care professionals working in the Public Dental Service (PDS) in south‐eastern Norway. A web‐based survey with a total of 557 dentists and dental hygienists in seven counties in Norway, with a response rate of 53.5%, was carried out in 2017. Dentists’ and dental hygienists’ activities regarding preventive snus use intervention were analysed using the chi‐square test. Intervention was measured with a score (1–5) based on four questions. Bivariate and multivariate linear regression analyses were used to investigate the associations between the explanatory variables of attitudes/activities and the outcome intervention variable. Approximately 87% of the dentists and 58% of the dental hygienists were not familiar with the “minimum intervention method” for tobacco prevention and cessation. Dental hygienists were most active in informing and supporting their patients in prevention and cessation of snus use. The PDS is an underutilized arena for tobacco prevention and cessation among adolescents, and the intervention potential is particularly high among the dentists.

  Background Current knowledge on treatment strategies and choice of restorative materials when treating deep caries or severe dental developmental defects (DDDs) in young individuals is scarce. Therefore, the aim was to investigate Norwegian dentists´ treatment decisions and reasons for treatment choice when treating deep caries in primary teeth and severe DDDs in permanent teeth in children. Methods A pre-coded questionnaire was sent electronically to all dentists employed in the Public Dental Service (PDS) in Norway (n = 1294). The clinicians were asked about their background characteristics and how often they registered DDDs. Three clinical cases were presented to the dentists and asked to prioritize treatment options and reasons for their choice. Results After three reminders, 45.8% of the dentists answered. Most clinicians were general practitioners (96.3%), females (77.9%), under 41 year-olds (59.4%), graduated in 2001 or later (61.1%), and representing all regions of Norway. The respondents registered molar incisor hypomineralisation (MIH), other DDDs and dental fluorosis (DF) frequently, 523 (91.1%), 257 (44.8%) and 158 (27.5%), respectively. In case 1a with severe dental caries in a primary molar, the preferred treatment was resin-modified glass ionomer cement (RMGIC) (58.3%), followed by glass ionomer cement (GIC) (17.9%) and zinc oxide-eugenol (ZOE) (13.2%). Extraction, compomer or stainless steel crowns (SSC) were preferred by 0.9, 0.7 and 0.4%, respectively. In case 1b, which was identical to case 1a, but treated under general anaesthesia, the preferred treatment alternatives were RMGIC (37.1%), resin composite (RC) (17.6%) and GIC (17.2%). Extraction and SSC were chosen by 15.1 and 7.2%, respectively. In case 2, showing a severely hypomineralised and symptomatic first permanent molar, the dentists preferred RC (38.4%), followed by RMGIC (26.6%) and GIC (19.0%). Extraction and SSC were chosen by 8.7 and 5.4%, respectively. The treatment choices were not significantly affected by the dentists’ background characteristics. The reasons for dentists’ treatment decisions varied for each patient case; patient cooperation, prognosis of the tooth and own experience were the dominant reasons. Conclusions A notable disparity in treatment choices was shown indicating that Norwegian dentists evaluate each case individually and base their decisions on what they consider best for the individual patient.

  «Nano» is a term that are increasingly used in advertising and marketing of dental products. A nanometer (nm) is a billionth of a meter (10-9 m). Nanotechnology is the manufacture and application of processes on the nano-scale. The “bottom-up” approach of nanotechnology implies manipulation of the single atoms to design structures with desired properties and function. It is tailoring on the atomic and molecular level. Nanotechnology is a new discipline. The application in dentistry is still rather simple, for example to make small particles from bigger structures (“top-down”). Nanoparticles are nano-objects that are used in current dental materials as fillers. A nanoparticle is defined as a structure having at least one dimension between 1 and 100 nanometer. Such particles exist in the domain between quantum chemistry and bulk chemistry, which cause the particles to behave differently than larger ones, due to high surface activity relative to the volume. The particles’ small size they may be so small that the do not interfere with light, making materials more transparent than their counterparts with coarser particles. So far, the main application of nanoparticles in dental products has been as passive fillers in restorative materials, represented in the so called nano hybrids and nano composites. Such materials show smooth surfaces, but there is still a lack of clinical data to evaluate the actual benefit of “nano-restoratives”. The application of present-day technology in restorative materials does not represent a quantum leap, but rather an evolution towards better materials. Nanomaterials with active functions are becoming more common. For example the use of antibacterial substances, e.g. nano silver or other metal oxides, in endodontic products. It is probable that the application of active nanostructures will increase, also for targeted release of minerals that can enhance mineralisation.

  Polymer-based dental restorative materials are designed to polymerize in situ. However, the conversion of methacrylate monomer to polymer is never complete, and leakage of the monomer occurs. It has been shown that these monomers are toxic in vitro; hence concerns regarding exposure of patients and dental personnel have been raised. Different monomer methacrylates are thought to cause toxicity through similar mechanisms, and the sequestration of cellular glutathione (GSH) may be a key event. In this study we examined the commonly used monomer methacrylates, 2-hydroxyethylmethacrylate (HEMA), triethylenglycol-dimethacrylate (TEGDMA), bisphenol-A-glycidyl-dimethacrylate (BisGMA), glycerol-dimethacrylate (GDMA) and methyl-methacrylate (MMA). The study aimed to establish monomers' ability to complex with GSH, and relate this to cellular toxicity endpoints. Except for BisGMA, all the monomer methacrylates decreased the GSH levels both in cells and in a cell-free system. The spontaneous formation of methacrylate-GSH adducts were observed for all methacrylate monomers except BisGMA. However, we were not able to correlate GSH depletion and toxic response measured as SDH activity and changes in cell growth pattern. Together, the current study indicates mechanisms other than GSH-binding to be involved in the toxicity of methacrylate monomers

  Background: Older adults (≥65 years) receiving municipal home health care services (HHCS) in Norway face substantial oral‑health challenges. One important reason is that HHCS and public dental services (PDS), organized at the county level, operate in separate organizational structures and use different digital systems. Currently, no integrated digital communication solution exists to support collaboration, and there is a clear need for improved cross‑sector coordination. Recent cost‑of‑illness evidence shows that poor oral health in this population entails considerable economic burden, including direct costs related to oral disease, indirect costs from increased risk of systemic illness, and productivity losses among caregivers. SYNCORAL is a digital platform embedded in electronic patient records designed to streamline patient identification, consent, and information exchange between HHCS and PDS. By enabling better coordination and earlier intervention, SYNCORAL may help shift care from costly acute treatment toward prevention. However, the key effects and costs of SYNCORAL remain uncertain. A Value of Information (VOI) analysis is therefore needed to assess whether additional evidence is required before large‑scale implementation. Aim: The aim of this VOI analysis is to quantify remaining decision‑critical uncertainty in the expected effects and costs of SYNCORAL, and to assess whether collecting additional evidence would be worthwhile. Method: We developed a Markov model (see Figure 2) and performed a probabilistic sensitivity analysis (PSA) using Monte Carlo simulation with 10 000 iterations to quantify parameter uncertainty. The model applied a lifetime time horizon, following older adults receiving HHCS from the age of 65 years old to death. Two separate analyses were conducted for adults aged 65–79 years and 80+ years. Data were obtained from epidemiological studies, national health registries, reimbursement databases, and expert assessments. Preliminary results: Substantial uncertainty across several key parameters is already evident while the VOI analysis remains in progress. Figure 3 shows the preliminary incremental cost‑effectiveness scatterplot of SYNCORAL versus current practice. Each point is one PSA simulation; the dashed line indicates a 275 000 NOK/QALY threshold, with points below the line considered cost‑effective. In these preliminary results, SYNCORAL appears cost‑effective in around 60% of simulations at this threshold. Further research: Our planned VOI work will estimate Expected Value of Sampling Information (EVSI) to quantify the value of reducing the uncertainty through new data, and Expected Net Benefit of Sampling (ENBS) to assess whether additional evidence would justify the cost of further research

  Introduction: Older adults (65+) receiving home health care services (HHCS) represent about 2% of Norway’s population. By 2050, the population aged 80+ is projected to double, which is expected to increase the demand for HHCS. Old age is associated with a high prevalence of oral diseases and poor oral health, which in turn is associated with elevated risks of systemic conditions. Despite these implications, the societal economic cost of oral health among older adults receiving HHCS is insufficiently documented. This study aimed to estimate current and future societal costs of reduced oral health among older adults receiving HHCS in Norway. Method: A cost-of-illness analysis was conducted. Direct costs included routine examinations and dental treatment, while indirect costs covered caregiver productivity losses and systemic diseases associated with reduced oral health. Data were obtained from epidemiological studies, national health registers, reimbursement registries, and expert elicitation. Results/conclusion: Older adults receiving HHCS accounted for 4.8% of dental health expenditures (NOK 1.1 billion) in 2026. In 2026, adults aged 80 years and more made up about 60% of total costs (NOK 919 million), compared with 40% for those aged 65–79 years (NOK 619 million). By 2060, this distribution is projected to shift to roughly 70% (NOK 2.3 billion) versus 30% (NOK 1 billion) Poor oral health among older adults receiving HHCS constitutes a substantial economic burden.

  Dental polymer-based composite materials are complex materials consisting of several components, the main components being filler particles (inorganic component) and polymer matrix (organic component). The organic component consists of monomers that usually are polymerized upon activation by visible light illumination. The polymerization process is never complete, and leakage of unreacted methacrylate monomers occurs during clinical service. Degradation processes may weaken the bond between the fillers and the matrix, leading to release of fillers particles and ions in addition to the organic components. Clinical handling during placement and finishing has been shown to cause release of particulate matter to the air in dental clinics, which could be followed by exposure to tissue and saliva of the patients. Thus, both dental personnel and patients could be exposed to components of polymer-based dental materials. The main objective of the thesis was to characterize the toxic potential of selected inorganic filler particles (barium glass particles and silica particles) and methacrylates (HEMA, TEGDMA, BisGMA, GDMA, MMA) used in dental composite filling materials. The results showed that both nano- and micro-sized filler particles could modulate the release of inflammatory mediators in vitro. The methacrylates investigated induced cytotoxicity, but the potency and the mechanism involved seemed to differ between the methacrylates. HEMA was found to induce apoptosis and DNA damage followed by activation of DNA damage response. To address possible exposure to multiple components of polymer-based dental composite materials the effect of co-exposure to components was studied. An additive inflammatory response was observed with particles and TEGDMA co-exposure. Studies on the mechanisms of possible adverse biological responses to substances released from polymer-based dental materials could contribute to safer dental materials.
