Tele-dentistry in COVID-19 era: A conduit for dental care in uncertain times.

Tele-dentistry encompasses all sorts of digital technologies that involve the exchange of patient's clinical data from a distant site for the provision of dental health care. Tele-dentistry has emerged from the concept of telemedicine, which has been in practice since the 19th century. In recent times, an upsurge in the digital technologies was noted, which has made the possibility of remote access to dental care. The outbreak of COVID- 19 pandemic has restricted the normal routine ways of clinical practice. In these challenging times, tele-dentistry serves as effective platform for providing dental health care. Tele-dentistry has vast applications across various disciplines of dentistry, including preventive dentistry, paediatric dentistry, oral medicine, and oral pathology etc. In these pandemic times, tele-dentistry can be efficiently used for identification of dental emergencies, allowing effective triage and subsequent management. There are different communication platforms available for tele-dentistry. The most common technologies used are web-based video conferencing and smart phone-based applications. As the clinicians are not aware of these digital technologies utilised in tele-dentistry, there are certain challenges associated with its use. In conclusion, tele-dentistry serves as an effective tool in providing health care in challenging times, but it has been underutilised by the dental fraternity. The legislative authorities should establish proper standard protocols to ensure the safety and confidentiality of patient information while using these digital platforms.

Oral health status of institutionalized older adults receiving domiciliary dental care: A cross-sectional retrospective study.

AIM: This study aimed to evaluate the oral health of care-dependent institutionalized older adults receiving domiciliary dental care. METHODS AND RESULTS: Dental health records of institutionalized adults receiving regular domiciliary dental care were examined (observation period: 5 years). Relevant demographic and oral health information were extracted. Statistical analyses included descriptive and non-parametric tests (α = .05). Records of 398 nursing home residents (mean-age: 84.9 ± 6.4 years) were included. Average time spent by the residents in the institution was 2.8 ± 1.5 years. The mean number of teeth present and the overall DMF-T score was 14.7 ± 9.1 and 27.4 ± 6.2, respectively. The DMF-T score increased until the 3-year recall, with a significant increase in the number of decayed teeth (2-year: p = .013; 3-year: p = .010). An improvement in the residents' periodontal health was seen during the observation period but was not statistically significant. CONCLUSION: The findings of this cross-sectional study confirmed that regular domiciliary dental care provision to institutionalized older adults helps maintain gingival and periodontal health. However, the incidence of dental caries might still be a problem that needs to be addressed with effective measures that improve the daily oral care provision to these older adults.

Association between early childhood caries and parental education and the link to the sustainable development goal 4: a scoping review.

BACKGROUND: The goal of the United Nations Sustainable Development Goal (SDG) 4 is to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all. The aim of this scoping review was to map the current evidence on the association between the prevalence of early childhood caries (ECC) and parental education; and to identify possible pathways by which parental education may protect against ECC. METHODS: The two questions that guided this review were: what is the existing evidence on the association between maternal and paternal education and ECC; and what are the pathways by which parental education protects against ECC? The initial search was conducted in January 2023 in PubMed, Web of Science and Scopus. Articles published in English between January 2000 and October 2022 that reported on the association between parental education and ECC were screened, and the extracted data were compiled, summarized, and synthesized. Review papers and non-primary quantitative research papers were excluded from the full-text review. Open coding was applied to develop a conceptual framework. RESULTS: In total, 49 studies were included: 42 cross-sectional, 3 case-control and 4 cohort studies. The majority (91.8%) reported on the associations between ECC and maternal (n = 33), paternal (n = 3), and parental (n = 9) level of education, and 13 (26.7%) reported on the association between parental education and the severity of ECC. Mothers with more than primary school education (n = 3), post-secondary/college/tertiary education (n = 23), and more than 4-12 years of education (n = 12) had children with lower risk for ECC. Two studies reporting on parental education found an association between maternal but not paternal education and ECC. The review suggests that achieving the SDG 4.1 may reduce the risk of ECC. Possible pathways by which maternal education protects from ECC were feeding practices, oral hygiene practices, and the use of dental services. CONCLUSION: The study findings suggests that higher maternal educational level may reduce the risk for the consumption of cariogenic diet, poor oral hygiene practices and poor use of dental services for caries prevention. However, the association between paternal education and ECC was not consistently observed, with significant associations less frequently reported compared to maternal education. Future studies are needed to define the magnitude and modifiers of the impact of maternal education on the risk for ECC.

Awareness and Incorporation of the Dental Home Concept Among General Dentists and Dental Therapists in Malaysia.

Background The dental home concept (DHC) refers to an approach in oral healthcare that emphasizes establishing a long-term, comprehensive, and family-centered relationship between a patient and their primary dental care. This study determined the awareness and incorporation of the DHC among general dentists and dental therapists in Malaysia. Methodology A total of 154 general dentists and 137 dental therapists providing oral healthcare services at the Ministry of Health (MOH) primary care facilities throughout Malaysia participated in this cross-sectional study. A self-administered questionnaire was used to measure the respondents' awareness of the DHC and incorporation of the DHC characteristics into their practice. Results Most dentists and dental therapists (61.7% and 67.2%, respectively) had not heard of the term DHC and were unaware of the concept. The respondents' awareness was not associated with their age, sex, years of service, facility location, and percentage of treatment given to children aged five years and below. However, most dentists and dental therapists responded positively about incorporating most DHC characteristics into their current practice. Conclusions Most dentists and dental therapists serving the MOH primary oral healthcare facilities were unaware of the DHC, although most DHC characteristics have already been incorporated into their practice. This study provides evidence of the incorporation of the DHC into the MOH primary oral healthcare services and suggests an effort to increase the awareness of the workforce regarding the concept and its implementation.

Socio-demographic predictors of not having private dental insurance coverage: machine-learning algorithms may help identify the disadvantaged.

BACKGROUND: For accessing dental care in Canada, approximately 62% of the population has employment-based insurance, 6% have some publicly funded coverage, and 32% have to pay out-of pocket. Those with no insurance or public coverage find dental care more unaffordable compared to those with private insurance. To support the development of more comprehensive publicly funded dental care programs, it is important to understand the socio-demographic attributes of all those, who find dental care unaffordable. METHODS: This study is a secondary analysis of the data collected from Ontarians during the latest available cycle of the Canadian Community Health Survey (2017-18), a cross-sectional survey that collects information on health status, health care utilization, and health determinants for the Canadian population. First, bivariate analysis was conducted to determine the characteristics of Ontarians who lack dental insurance. Afterwards, we employed machine learning (ML) to analyze data and identify risk indicators for not having private dental insurance. Specifically, we trained several supervised ML models and utilized Shapley additive explanations (SHAP) to determine the relative feature importance for not having private dental insurance from the best ML model [the gradient boosting (GBM)]. RESULTS: Approximately one-third of Ontarians do not have private insurance coverage for dental care. Individuals with an income below $20,000, those unemployed or working part-time, seniors aged above 70, and those unable to afford to have their own housing are more at risk of not having private dental insurance, leading to financial barriers in accessing dental care. CONCLUSION: In the future, government-funded programs can incorporate these identified risk indicators when determining eligible populations for publicly funded dental programs. Understanding these attributes is critical for developing targeted and effective interventions, ensuring equitable access to dental care for Canadians.

[Improving the effectiveness of local anesthesia in patients with arterial hypertension in the provision of emergency dental care]. / Povyshenie effektivnosti mestnogo obezbolivaniya u patsientov s arterial'noi gipertenziei pri okazanii neotlozhnoi stomatologicheskoi pomoshchi.

THE AIM OF THE STUDY: Was to evaluate the use of Ketorol Express as a preventive analgesia to increase the effectiveness of local anesthesia in providing emergency dental care to patients with arterial hypertension. MATERIALS AND METHODS: The study was conducted on the basis of the state autonomous healthcare institution of the Moscow region «Royal Dental Clinic¼ with the participation of 83 people. The patients were divided into two groups. In group 1, Ketorol Express was prescribed as a preventive analgesia in a dosage of 20 mg before local anesthesia. Patients of group 2 underwent dental interventions without the use of preventive analgesia. A 3% solution of mepivacaine was used as a local analgesic solution. For a subjective assessment of the effectiveness of anesthesia, use a visual analog scale. All patients had their blood pressure and heart rate measured before and after the interventions and hemodynamic parameters were continuously monitored during emergency dental care. RESULTS: In group 1, the effectiveness of combined anesthesia with the infiltration method of local anesthetic administration was 93±1.17%, according to the patient, 94±1.47%, according to the doctor, with the conductive method of anesthesia at the mandibular orifice - according to the patient it was 91±1.01%, according to the doctor 92± 1.36%. In group 2, when providing emergency dental care with the infiltration method of administration of 3% mepivacaine the anesthesia was effective in 80±1.97% of cases according to the patient and in 80±1.17% of cases according to the doctor, with the conductive method of anesthesia at the mandibular orifice, the effectiveness of anesthesia according to the patient was 82±1.11%, according to the doctor 85±1.23%. CONCLUSION: The results of the study demonstrated a statistically significant increase in the effectiveness of local anesthesia performed with a 3% solution of mepivacaine in patients with arterial hypertension due to the use of preventive analgesia with Ketorol Express at a dosage of 20 mg (2 tablets of 10 mg) in emergency dental care with registration and analysis of changes in hemodynamic parameters.

Dental Profile of Brazilian Patients with Rare Skeletal Genetic Disorders: Clinical Features and Associated Factors.

The aim of this study is to compare the dental profiles of Brazilian patients with rare genetic skeletal disorders and normotypical patients. A cross-sectional study was carried out with 210 individuals aged between 2 and 54 years old [105 with rare diseases (Mucopolysaccharidosis/MPS n = 27 and Osteogenesis Imperfecta/OI n = 78) and 105 without rare diseases] and their parents/caregivers. The parents/caregivers answered a questionnaire about individual aspects of their child and the dental profile was identified from questions related to dental history and the presence/absence of dental problems. The patients' oral cavity was also examined by three examiners for dental caries, malocclusion, gingivitis, and dental anomalies. The average age of individuals with a rare disease was 14.1 years (±12.2) and the median was 9.5 years. Participants who had already used the public health system (SUS) dental care services had a 2.24 times higher chance of belonging to the group with a rare disease (OR = 2.24; 95% CI: 1.07-4.89). Patients with rare diseases are 14.86 times more likely to have difficulty receiving dental treatment (OR = 14.86; 95% CI: 5.96-27.03) and 10.38 times more likely to have one or more dental problems (OR = 10.38; 95% CI: 1.95-35.17). Individuals with rare disorders have a greater history of difficulty in accessing dental treatment, using the SUS, and were diagnosed with more dental problems compared to normotypical individuals.

Artificial Intelligence through Wireless Sensors Applied in Restorative Dentistry: A Systematic Review.

The integration of wireless sensors with artificial intelligence could represent a transformative approach in restorative dentistry, offering a sophisticated means to enhance diagnostic precision, treatment planning, and patient outcomes. This systematic review was conducted to pinpoint and assess the efficacy of wireless sensors in restorative dentistry. The search methodology followed the guidelines outlined by PRISMA and involved the utilization of prominent scientific databases. Following the final phase of evaluating eligibility, the systematic review included six papers. Five experiments were conducted in vitro, while one was a randomized clinical trial. The investigations focused on wireless sensors for cavity diagnosis, toothbrush forces, facial mask applications, and physiological parameter detection from dental implants. All wireless sensors demonstrated efficacy in achieving the objectives established by each study and showed the validity, accuracy, and reproducibility of this device. The investigations examined in this systematic review illustrate the potential of wireless sensors in restorative dentistry, especially in the areas of caries detection, dental implant systems, face masks, and power brushes. These technologies hold promise for enhancing patient outcomes and alleviating the workload of dental practitioners.

Is there an association between head and neck cancer diagnosis and self-reported dental fear? A dual-center cross-sectional study.

Introduction: Mental distress is highly reported in cancer patients, resulting in anxiety and depression most of the time. Both conditions, in turn, are recognized to be related to dental fear in adults; however, there are no studies on patients suffering from head and neck cancer. Thus, the present study aimed to investigate whether newly diagnosed patients with head and neck cancer are more prone to self-reported dental fear. Material and Methods: This dual-center cross-sectional study was conducted with 25 healthy outpatients and 25 patients with a recent diagnosis of head and neck cancer, all requiring dental care. The patients were informed at the first appointment about their dental therapy planning and the Brazilian Portuguese Version of the Dental Fear Survey (DFS) questionnaire was then applied after appropriate instructions. Results: The DFS total scores did not differ statistically between the groups (Mann-Whitney U test, P = 0,120) but the Cancer Group presented a slightly higher mean score (32.2 ± 10.0) than the Control Group (30.0 ± 14.2). Conclusion: Within the limitations of this study, newly diagnosed patients with head and neck cancer and healthy individuals seem to experience similar self-reported dental fear.

Surgical outcomes of the surgical techniques following management of iatrogenic trigeminal nerve injuries: A systematic review.

Objective: To investigate the effectiveness of the microsurgical treatment in restoring full sensory recovery following trigeminal nerve injuries caused by iatrogenic oral and maxillofacial surgical interventions. Methods: A detailed search was conducted on the Cochrane central register of controlled trials, Medline and Embase. Clinical studies with at least twelve months of follow up were included and assessment of risks of bias was made using the Robbin I assessment tool. Results: Six studies were identified in the searches which include 227 patients. The lingual nerve was the most common injured nerve, followed by the inferior alveolar nerve. Third molar removal was the most frequent cause of nerve injury, followed by root canal treatment, pathology excision, coronectomy, orthognathic surgery, dental implants and then local anaesthetic injections. Overall, surgical interventions for nerve injuries showed neurosensory improvement postoperatively in the majority of patients. Conclusion: Direct neurorrhaphy is still the gold-standard technique when the tension at the surgical site is minimal. Promising results have been noted on conduit applications following traditional repair or grafting. Further research is needed on the efficacy of allografting and conduit applications in nerve repair.

Using virtual reality to manage pain and anxiety during dental treatments in patients with stroke: A case series.

Dental anxiety is common post-stroke, with many patients unable to receive standard anesthetics. Virtual reality has been increasingly used to manage pain and anxiety in dentistry, though its use in individuals with stroke is largely unexplored. A case series of two patients with a history of stroke and dental anxiety was conducted at a specialized dental clinic. Patients watched 360°-virtual reality videos in a dental chair using a head-mounted display. Outcomes (patient: dental anxiety and pain, reactions to virtual reality; dental team: system usability, impact on workflow) were assessed using a standard observation tool, questionnaires, and interviews. Both patients wore virtual reality throughout the procedure and reported that the device was comfortable, provided a distraction, and had potential to reduce anxiety/pain. The dentist reported a positive impact on patient anxiety and time to complete procedures, and intends to continue using virtual reality with other stroke patients and clinical populations.

Fissure Sealants or Fluoride Varnish? A Randomized Pragmatic Split-Mouth Trial.

This study aimed to compare the clinical effectiveness of resin-based fissure sealants (FS) and fluoride varnish (FV) in children at high caries risk. A practice-based split-mouth randomized clinical trial was conducted at 9 Public Dental Service (PDS) clinics in Norway. In total, 409 children age 6 to 10 y at high caries risk (d3mft > 0) meeting inclusion criteria were recruited by dentists and dental hygienists during routine examination. Eligibility criteria were 2 fully erupted first permanent molars (FPMs) in the same jaw, with sound occlusal surfaces or with initial caries. Participation was voluntary, caregivers and eligible children were informed about the study, and written parental consent was obtained. FS and FV were randomly applied on contralateral FPMs in the same jaw, with each participant serving as their own control. FS was applied at baseline and thereafter maintained according to clinicians' conventional procedures, whereas FV was applied at baseline, 6 mo, and 12 mo. The study outcome was success, with no need for invasive treatment (caries control), while failure was defined as dentin carious lesion or restoration. Two-level mixed-effects logistic regression analysis was used to compare FS and FV groups. Of 409 recruited children, 369 (90%) children/tooth pairs were examined after 36 mo. Intention-to-treat analysis showed 94.1% adjusted predicted probability (aPP) of success (95% confidence interval [CI] 91.7 to 96.4) in the FS group and 89.6% aPP (95% CI 86.5 to 92.7) in the FV group. In the adjusted analysis, the FV group had a lower OR for success compared with the FS group (OR 0.54, 95% CI 0.24 to 0.87). In the population studied, the clinical effectiveness of FS was statistically significantly higher compared with FV but below the estimated minimal clinically important difference of 10%.

Nursing home residents' perspectives on oral health: An in-depth interview study.

Background: Oral health is associated with general health and care dependency, but is often neglected in nursing homes. Integration of oral care into general care is necessary, but is hampered by multiple barriers at different levels. This study is part of research into the implementation of the new Oral Health Section for use within the interRAI Long-Term Care Facilities instrument, which is used to assess care needs of nursing home residents. This new Oral Health Section evaluates nine aspects of oral health and results in two Collaborative Action Points. Objective: To identify residents' perspectives on oral health, oral care, and on the assessment of their oral health using the new Oral Health Section. Design: Qualitative design using in-depth interviews. Settings: Three nursing homes. Participants: Residents were selected using purposeful sampling in nursing homes participating in research evaluating the use of the new Oral Health Section. The selection was based on their oral status for maximum variation and on their cognitive performance score. Twenty-two residents from three Flemish nursing homes agreed to participate. Methods: Residents' oral health was assessed using the new Oral Health Section and dental indices. In-depth interviews were conducted, including the validated short-form Oral Health Impact Profile to evaluate the impact of oral conditions on residents' well-being. The interviews were coded and analysed by three researchers and mapped into a model to understand participants' oral health behaviours. Results: Low Oral Health Impact Profile scores indicated a low impact of oral health issues on participants' lives. However, despite 77.3 % of the participants reporting satisfaction with their oral health, 86.4 % had poor oral hygiene and 68.2 % required referral to a dentist, suggesting a tendency to overestimate their oral health. Their oral health behaviour was determined by a lack of oral health knowledge (Capability), positive attitudes towards oral health and autonomy (Motivation), upbringing and social support (Opportunity). Participants considered assessments with the new Oral Health Section acceptable. Conclusions: This study shows how older people perceive their oral health and oral healthcare. Understanding their wishes and needs will not only facilitate their involvement in their oral care, but is also likely to enable the improvement of their oral hygiene and the development of effective oral care strategies for the future. Policy makers and managers of care organisations may use these results to foster integration of oral care guidelines into care protocols within nursing homes, including collaboration with dentists and dental hygienists. Tweetable abstract: Oral health assessments with the new Oral Health Section for use within interRAI were positively perceived by nursing home residents.

Factors associated with dental interns and professors perception of the management of disabled patients: A cross-sectional study under multivariable analysis.

Background: Patients with disabilities experience oral health inequalities, including increased disease prevalence and unmet healthcare needs. The aim of this study was to assess factors associated to the perceived management of patients with physical disabilities among dental interns and professors at a university located in the capital city and a branch in a province in Peru. Methods: This cross-sectional, observational, and analytical study included 100 dental interns and 75 Peruvian dental professors and was conducted from January to April 2022. A validated perception scale was used to evaluate the management of disabled patients. For the statistical analysis, the study employed Pearson's chi-square test and Fisher's exact test, along with a Poisson regression model that used robust variance. The adjusted prevalence ratio (APR) was utilized to evaluate perception while taking into account factors such as gender, age, marital status, origin, professional experience, previous treatment of a patient with physical disability, and previous cohabitation with a disabled patient. The significance level was set at p < 0.05. Results: The 86 % of dental interns and 88 % of dental professors had a poor perception of managing disabled patients, with no significant association between them (p = 0.698). Male and female dental interns displayed significant differences in perception (p = 0.004), while no other variables showed significant differences (p < 0.05). Conversely, dental professors displayed significant differences in all variables analyzed (p < 0.05). In dental interns, gender was found to be the only influential variable, with females having a 41 % higher likelihood of perceiving disabled patient management poorly compared to males (APR = 1.41; 95 % CI: 1.04-1.91) (p = 0.028). However, gender was not found to be a significant factor for dental professors (p = 0.449). Conclusion: The majority of dental interns and professors had a poor perception of managing disabled patients, with no significant differences observed between them. Moreover, gender significantly influenced the perception of managing patients with physical disabilities among dental interns specifically. On the other hand, neither age, marital status, origin, professional experience, previous treatment of a patient with physical disability, nor previous cohabitation with a disabled patient were found to be associated factors among dental interns and professors.

Painless cost control as a central strategy for universal oral health coverage: A critical review with policy guide.

AIM: This study aimed to critically review the methods used to control the significantly increasing costs of dental care. METHODS: Through a comprehensive search of the available literature, the cost control (CC) mechanisms for health services were identified from a healthcare system perspective. The probable applicability of each CC method was evaluated mainly based on its potential contribution to oral health promotion. Each mechanism was then classified and discussed under any of the two headings of financing and service provision. An operational guide was finally presented for policy-making in each of the three main models of healthcare systems, including National Health Services, social/public health insurance and private insurance. RESULTS: From a total of 142 articles/reports retrieved in PubMed, 73 in Scopus and 791 in Google Scholar, 35 were included in the final review after eliminating the duplicates and screening process. Totally ten mechanisms were identified for CC of dental care. Seven were discussed under the financing function, including cost sharing, preauthorization, mixed payment method and an evidence-based approach to benefit package definition, among others. Three further methods were classified under the service provision function, including workforce skill mix with emphasis on primary oral healthcare providers, development of primary healthcare (PHC) network and an appropriate use of tele-dentistry. CONCLUSION: Painless control of dental expenditures requires a smart integration of prevention into the CC plans. The suggested policy guide emphasizes organizational factors; particularly including the development of PHC-based networks with midlevel providers (desirably extended-duty dental hygienists) as the frontline oral healthcare providers.

Tooth Discoloration from 2 Silver Fluorides Used in Adults with Special Needs: A Randomized Trial.

BACKGROUND: Discoloration of carious lesions after application of silver diamine fluoride lowers patient acceptance and limits its wider use for caries arrest. OBJECTIVE: To assess lesion and tooth color changes from 2 novel silver fluoride (AgF) products and its relationship to caries activity (clinical visuo-tactile scores) and bacterial load (using laser fluorescence with the DIAGNOdent). METHODS: A split-mouth design was followed, with matched smooth surface carious lesions in the same arch in adults with special needs randomized for 1-min treatments with AgF/potassium iodide (KI) (Riva Star Aqua, SDI) and AgF/stannous fluoride (SnF2) (Caries Status Disclosing Solution; Whiteley). Standardized images taken at baseline, immediately postoperatively, and at 3-mo review were subjected to digital image analysis to calculate delta-E and to track changes in luminosity of carious lesions. RESULTS: Twelve participants were recruited in the study. A total of 56 teeth (28 pairs) were included. Significantly greater changes were seen in treated lesions than in the adjacent noncarious natural tooth structure, both immediately after treatment and at the 3-mo review (P < 0.0001). Color change and caries activity were not affected by tooth type, tooth location, plaque status, salivary status, or special needs condition. AgF/SnF2 caused transitory darkening immediately on application, while AgF/KI caused the immediate formation of yellow deposits (silver iodide). Both products caused significant darkening of treated lesions at 3 mo (P = 0.0009; P = 0.0361), with no differences between them (P = 0.506). Responding lesions showed larger and more perceptible color changes immediately after either AgF application (P = 0.002; P = 0.024). CONCLUSIONS: Both AgF products were highly effective for caries arrest in this patient population. Despite minor differences in the appearance of treated lesions at the time of application, both products lead to similar darkening of treated sites at 3 mo. KNOWLEDGE TRANSFER STATEMENT: This study shows the usefulness of silver fluoride used in conjunction with potassium iodide or stannous fluoride for achieving caries arrest in smooth surface lesions in adults with special needs. Patients need to be informed that long-term staining of the lesion occurs with both, similar to silver diamine fluoride.

Primary care dentistry: An Australian perspective.

INTRODUCTION: Primary care dentistry is the first point of contact that someone has with the dental system and is predominantly focused on the treatment and prevention of dental caries and periodontal disease. The aim of this paper was to review the Australian primary dental care system. METHODS: This paper reviews the primary dental care system in Australia, drawing on data reporting on the dental workforce, funding sources for dental care, oral health outcome measures and dental visiting patterns. RESULTS: Primary dental health care in Australia is predominantly provided by dentists working in private practice, with the number of dentists per 100,000 people in Australia increasing from 46.9 in 2000 to 65.1 in 2022. However, there has been a gradual shift over the past twenty years towards greater service provision by other members of the dental team who now represent one quarter of the dental workforce, and some expansion of publicly funded dental care. Despite this dentistry remains isolated from the rest of primary health care, and the lack of government funding means that many people continue to miss out of necessary dental care, particularly those living in regional and rural Australia and from low-income groups. CONCLUSIONS: Australians should be able to access primary dental care services when and where they need it with adequate financial protection, from services that are well integrated into the broader primary health care system to ensure they are able to achieve optimal oral and general health. For many Australians, this is not currently the case. CLINICAL SIGNIFICANCE: Australia is at a crossroads with respect to access to dental care, and there is a need for stronger advocacy from stakeholders to improve oral health outcomes and reduce inequalities.

Assessing the role of dental insurance in oral health care disparities in Canadian adults.

Background: This study examines the association of dental insurance with oral health care access and utilization in Canada while accounting for income and sociodemographic factors. It contributes to a baseline of oral health care disparities before the implementation of the Canadian Dental Care Plan (CDCP). Data and methods: This retrospective study of Canadians aged 18 to 64 years is based on data from the 2022 Canadian Community Health Survey. Multivariable logistic regression was employed to evaluate the association of dental insurance with the recency and frequency of dental visits, as well as avoidance of dental care because of cost. Results: Overall, 65.7% of Canadians reported visiting a dental professional in the previous year: 74.6% of those with private insurance, 62.8% with public insurance, and 49.8% uninsured. Cost-related avoidance of dental care was 16.0%, 20.9%, and 47.4% for the privately insured, publicly insured, and uninsured, respectively. After adjustment, adults with private (odds ratio [OR]=2.54; 95% confidence interval [CI]: 2.32 to 2.78) and public (OR=2.17; 95% CI: 1.75 to 2.68) insurance were more likely to have visited a dental professional in the last year compared with those without insurance. Similarly, both private (OR=0.22; 95% CI: 0.20 to 0.25) and public (OR=0.22; 95% CI: 0.17 to 0.29) insurance holders showed a significantly lower likelihood of avoiding dental visits because of cost when compared with uninsured individuals. Interpretation: This study showed the significant association of dental insurance with access to oral health care in Canada, contributing to setting a critical benchmark for assessments of the CDCP's effectiveness in addressing oral health disparities.

Advancing dental care access for patients with disabilities: A global scoping review of predoctoral training.

OBJECTIVE: To examine predoctoral training programs that address the unique needs of patients with special healthcare needs (SHCN) and provide an overview of current global training initiatives, while exploring innovative approaches to enhance dental students' preparation in managing SHCN patients. METHODS: A scoping review (SR) was conducted focusing on three key concepts: dental education, pre-doctoral training, and intellectual disability/developmental disability. The search encompassed five databases including Medline, Embase, Dentistry and Oral Sciences Source (EBSCO), Global Health (EBSCO), and WHO Global Index Medicus, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. EndNote and Covidence were utilized to prevent duplication and facilitate title/abstract screening. RESULTS: After screening abstracts, a total of 2309 articles were initially identified with 28 articles meeting eligibility criteria for data extraction relevant to the research question. Two major categories characterized the key findings included in the review: 12 interventional studies and 16 perception-based studies. CONCLUSION: This SR revealed that dental students are not adequately trained to treat special needs populations; consequentially, dental students lack confidence in providing high-quality care to this demographic. The absence of standardized training poses a global challenge, exacerbating care disparities. Addressing this issue is crucial to better prepare dental students and advance equitable access and quality care for underserved populations.
