Barriers and facilitators for oral health screening among tobacco users: a mixed-methods study

ObjectivesTobacco consumption adversely affects general and oral health and is considered one of the significant public health burdens globally. The present study aims to assess the barriers and facilitators for attending oral and dental health screening among tobacco users who seek cessation advice.MethodologyThe present mixed-methods study used group concept mapping (GCM) to identify the facilitators/barriers to attending oral health screening among young adults attending face-to-face and virtual Tobacco Cessation Clinic at King Saud University (Riyadh, Saudi Arabia) between September 2022 and April 2023. Study investigators included healthcare social workers, dental interns, and oral and maxillofacial medicinists. Information about demographics, general health, oral/dental health and tobacco use were collected using self-completed questionnaires. The barriers and facilitators were assessed following GCM by brainstorming, sorting, rating, and interpretation activities. Descriptive, multidimensional scaling and hierarchical cluster analysis were used to describe the study participants and produce concept maps of the generated statements.ResultsThe study included 148 participants who generated 67 statements summarised into 28 statements as facilitators or barriers. Based on a 5-point importance scale, the participants indicated the importance of facilitators under health-related cluster [e.g. when I feel pain] as the highest, followed by personal [e.g. to maintain my mouth hygiene], social [e.g. the quality of treatment] and financial clusters [e.g. the reasonable cost]. Concerning barriers, financial factors [e.g. high cost] acted as the highest-rated barrier, followed by personal [e.g. lack of dental appointments] and health-related [e.g. worry that dental problems will worsen]. The social factors were the least considerable barrier [e.g. lack of time]. Clustering these facilitators/barriers on the concept map indicated their conceptual similarity by an average stress value of 0.23.ConclusionPain was the most important facilitator to attending oral health screening by young adults seeking tobacco cessation advice. Notable barriers included the high cost of dental treatment and the lack of scheduled appointments. Thus, oral health care providers need to consider scheduling periodic and timely dental check-ups to prevent and reduce the burden of tobacco-associated and pain-causing oral diseases.

Estimation of Oral Disease Burden among Older Adults in LTC: A Scoping Review.

Oral health is an essential part of healthy aging and very little data exists around the disease burden for older adults in a long-term care setting. The aim of this scoping review was to estimate the disease burden of dental caries, periodontal disease, and tooth loss among older adults in Long-Term Care (LTC). This scoping review was conducted in accordance with the Joanna Briggs Institute methodology. A detailed strategy was used to conduct a comprehensive search of electronic databases: PubMed, Embase, and Dentistry and Oral Sciences Source (DOSS). The Rayyan AI platform was used to screen abstracts for assessment by one of five co-investigators. Results indicate that only one in three might have a functional dentition upon entry into LTC, and among those who are dentate, most might expect to develop at least one new coronal and one new root caries lesion each year. There is a need to better document the disease experiences of this group to tailor approaches to care that might reduce the avoidable suffering as a result of dental caries and periodontal disease.

Dental Caries among the Elderly in Iran: A Meta-analysis.

The prevalence of dental caries among the elderly is high worldwide, and dental caries cause the major burden of oral diseases. This meta-analysis aimed to determine the dental caries experience among the elderly in Iran. A systematic review of the published and grey literature on Iranians aged 65 years or older was performed. Six international and local databases provided the most comprehensive population-based studies. National oral health surveys and national disease and health surveys were considered other primary data sources. The quality of remained studies was assessed by a modified tool designed based on the STROBE statement checklist to evaluate the cross-sectional studies. R Version 3.6.0 was used for statistical analysis. Heterogeneity was assessed using Cochran's Q and F statistics. Subgroup analysis was performed to detect the source of heterogeneity. Funnel plots and Egger's regression intercept test were used to assess publication bias and selective reporting. Overall, 3099 sources were found. After excluding ineligible studies, 46 data points with 10411 people ≥65 years were included in the meta-analysis. The mean pooled decayed, missing, and filled teeth (DMFT) among older people was 26.84 (range, 26.41-27.28). The DMFT was 26.78 (range, 26.12-27.43) in women and 26.91 (range, 26.32-27.50) in men. The mean number of decayed teeth was 1.48 (range, 1.32-1.65). The mean pooled missing teeth was 24.83 (range, 24.20-25.46), and the mean pooled filled teeth was 0.14 (range, 0.12-0.17). The majority (92%) of the DMFT was related to missing teeth. Iranian elderly have almost 5 sound teeth in their mouth on average. The Iranian oral health policymakers should address this considerable burden of dental caries in designing and implementing better oral health policies for the population, especially older Iranian adults.

Dentifrices. Part 1: a general introduction

This comprehensive review traces the evolution of dentifrices from ancient concoctions to modern formulations, evaluating their role in oral health and environmental impact. Despite the global burden of oral diseases, notably dental caries and periodontitis, advancements in dentifrice technology have contributed to the decline in caries prevalence, although periodontitis remains a challenge. The historical perspective outlines the transition from abrasive powders to fluoride-enriched pastes, emphasizing the significance of toothbrushing frequency and technique, alongside the use of dentifrices, for effective plaque control and caries prevention. The modern era has seen a proliferation of dentifrice variations, with a focus on cosmetic attributes often overshadowing therapeutic benefits. The review also discusses the environmental considerations of dentifrice production and disposal, highlighting the shift towards sustainable packaging and ingredient transparency. The market analysis reveals a mature industry with a projected growth, influenced by consumer preferences and oral hygiene awareness. CPD/Clinical Relevance: Regular toothbrushing with fluoridated dentifrice remains a cornerstone of oral hygiene practices, directly influencing the reduction of plaque accumulation and the incidence of caries and periodontitis.

Oral frailty among dentate and edentate older adults in long-term care

BackgroundThe objectives of this study were to compare oral frailty (OFr) among edentate and dentate older adults living in long-term care facilities (LTCF) and to clarify how edentulism and oral disease burden (ODB) of dentate older adults are associated with OFr.MethodsThe population of this study comprised 94 edentate and 209 dentate residents in LTCF in Helsinki, Finland, who had previously participated in a nutritional study. The participants underwent a clinical oral examination. The dentate residents were further divided into three ODB groups based on asymptotic dental score. The edentate and different ODB groups were compared with each other regarding demographics and oral and medical findings. OFr was defined as ≥ 2 of following: having a diet of soft/pureed food, residue of food in the oral cavity, inability to keep the mouth open during examination, unclearness of speech, dry mouth. The association between OFr and edentulousness and various levels of ODB was analyzed by a multivariate logistic model.ResultsParticipants with low ODB had significantly less OFr than their edentate peers (p = 0.009). Furthermore, the edentate and dentate with high ODB had similar odds for OFr.ConclusionsEdentulousness and high ODB are equally harmful conditions and may predispose to OFr. This study suggests that maintaining healthy natural teeth and good oral health (low ODB) may protect against OFr.Trial registrationThe Ethics Committee of the Hospital District of Helsinki and Uusimaa approved the protocols for the nutritional status and oral healthcare studies and the merging of the data, including patient medical records (Register number HUS/968/2017).

A mixed methods evaluation of the effectiveness of an oral health training program for disability care workers in Burkina Faso

BackgroundWhile efforts to improve the oral health of vulnerable populations have received little attention in general, the situation of children with disabilities in low- income countries (LICs) remains especially challenging. The present study evaluated the effectiveness of an oral health training provided to disability care workers in Ouagadougou, Burkina Faso thereby contributing to closing the knowledge gap in disability research in relation to oral health in LICs.MethodsThis was a single-arm pre-post study following an embedded mixed methods design using the New World Kirkpatrick training effectiveness evaluation model. For the purposes of this study, three levels of the Kirkpatrick (KP) evaluation were considered: reaction, learning and behaviour.ResultsA total of 44 care workers from 6 disability centres participated in the study. Care worker post-training scores (Md = 17) were significantly higher compared to pre-training scores (Md = 13) [Wilcoxon signed-ranks test: Z= -5.53, p < .001, r = .59.] The median value for care worker confidence in applying training material in their everyday job was 7 out of 10 points (IQR = 3). At the 1-month training follow-up, 3 centres had implemented daily toothbrushing for people with disabilities.ConclusionThese findings suggest that tailored training led to an increase in care worker confidence and motivation to implement oral health activities, in knowledge about oral health and a partial implementation uptake of daily toothbrushing in disability centres. Further long-term evaluations with dental care provision in rural and urban settings are needed to lower the high oral disease burden of people with disabilities in Burkina Faso.

Factors affecting oral health in children and adolescents in Ecuador

Globally, the highest prevalence of caries in permanent teeth is found in the Andean region of Latin America. In countries such as Ecuador, the burden of oral diseases has shown an increase in recent years. The present study aimed to identify the risk factors associated with dental pain in children and adolescents aged 5 to 18 years in Ecuador, in order to base preventive actions to improve oral health in this population. Using the database of the National Health and Nutrition Survey, a sample of 23,621 participants was analyzed. The analysis included variables such as ethnic self-identification, region of residence, housing area, and maternal educational level, in addition to the economic impact of dental pain. The results showed that approximately one third of children and adolescents experienced dental problems that affected their quality of life in the last 12 months. The data revealed that dental pain, difficulties in chewing, speaking, and sleeping, as well as school absences due to dental problems, were common. Significant differences were found in the impact on quality of life associated with ethnicity, region, area of residence and maternal educational level. Residents of rural areas, indigenous people and children of mothers with basic education had a higher prevalence of dental problems. The conclusions highlight the need to develop preventive strategies adapted to risk groups, promoting specific interventions to reduce dental pain and improve oral health

Evaluation of oral health services and challenges faced by oral health practitioners working in Nyarugenge, Rwanda.

Oral healthcare professionals encounter considerable challenges while providing services to curb the oral disease burden. The aim of this study was to explore the challenges faced by oral health practitioners providing oral health services in Nyarugenge, Rwanda and to appraise the availability and adequacy of oral hygiene equipment, instruments, and materials. This was a cross-sectional concurrent mixed methods study. The quantitative and qualitative parts were independent during data collection and analyses and merged during the interpretation phase. All seven public health facilities and 14 dental professionals working in Nyarugenge were included in the study. Data were collected using an audit checklist and an in-depth interview guide. Descriptive statistics were used to analyze the quantitative data. The interviews were analyzed using thematic content analysis. Most of the dental health professionals were dental therapists (n = 11), women (n = 9), aged 31-40 years (n = 7), and with 11-20 years' experience as oral health practitioners (n = 6). There were five health centers and two hospitals that were audited for equipment, instruments, and materials. The audit of the facilities revealed that most facilities have dental equipment and instruments, but none have adequate preventive dental instruments and materials. Four broad themes emerged from the interviews with the oral health practitioners, namely human resources, supply chain management, patients' oral health awareness and service rendering, and strategic management and administration. The most significant challenges oral health practitioners faced included high dental practitioner/patient ratios, lack of adequate and appropriate equipment and materials, patients' lack of oral health awareness, and a lack of administrative support. Well-established community preventive interventions, such as a mobile oral health App, could reduce the patient/provider ratio by increasing population awareness of oral health and encouraging healthy behaviours. The management of the health facilities should address the human resource challenges and equipment supply chain issues.

It emphasizes the potential for enhancing access to healthcare resources to create a healthier community and maintain social harmony.

Oral Health, Social and Emotional Well-Being, and Economic Costs: Protocol for the Second Australian National Child Oral Health Survey.

Given the significant investment of governments and families into the provision of child dental care services in Australia, continued population oral health surveillance through national oral health surveys is imperative. The aims of this study are to conduct a second National Child Oral Health Survey (NCOHS-2) to (1) describe the prevalence, extent, and impact of oral diseases in contemporary Australian children; (2) evaluate changes in the prevalence and extent of oral diseases in the Australian child population and socioeconomic subgroups since the first National Child Oral Health Study (NCOHS-1) in 2012-2013; and (3) use economic modeling to evaluate the burden of child oral disease from the NCOHS-1 and NCOHS-2 and to estimate the cost-effectiveness of targeted programs for high-risk child groups. The NCOHS-2 will closely mimic the NCOHS-1 in being a cross-sectional survey of a representative sample of Australian children aged 5-14 years. The survey will comprise oral epidemiological examinations and questionnaires to elucidate associations between dental disease in a range of outcomes, including social and emotional well-being. The information will be analyzed within the context of dental service organization and delivery at national and jurisdictional levels. Information from the NCOHS-1 and NCOHS-2 will be used to simulate oral disease and its economic burden using both health system and household costs of childhood oral health disease. Participant recruitment for the NCOHS-2 will commence in February 2024. The first results are expected to be submitted for publication 6 months after NCOHS-2 data collection has been completed. Thematic workshops with key partners and stakeholders will also occur at this time. Regular surveillance of child oral health at an Australian level facilitates timely policy and planning of each state and territory's dental public health sector. This is imperative to enable the most equitable distribution of scarce public monies, especially for socially disadvantaged children who bear the greatest dental disease burden. The last NCOHS was conducted in 2012-2014, meaning that these data need to be updated to better inform effective dental health policy and planning. The NCOHS-2 will enable more up-to-date estimates of dental disease prevalence and severity among Australian children, with cost-effective analysis being useful to determine the economic burden of poor child dental health on social and emotional well-being and other health indicators.

Developing a Traditional Oral Health Education Folktale for Primary School Pupils in Ibadan, Oyo State, Nigeria

BACKGROUND: Worldwide oral diseases are a major public health problem among children. Oral health education directed at major aetiological factors such as diet, oral hygiene and dental clinic attendance has helped to reduce the burden of oral diseases in children. Folklore, which includes folktales, puppet shows, dramas, folk music, and dance, appears to be a promising tool that could gain and engage young people's interest. Traditional folktale in school-based health education in Nigeria has not yet undergone much research or evaluation.&#x0D; AIM: This paper aims to report how a local traditional folktale for oral health education among primary school pupils was developed with a view to providing information on how the folktale can be developed in other languages as well as how other oral health education folktales can be developed.&#x0D; METHOD: Oral health professionals, linguist and theater arts experts from the University of Ibadan, Nigeria, developed a traditional folktale represented on a graphically designed banner (comic strips) for use as an oral health education tool for primary school pupils. Developing the tool involved certain processes which were validated and evaluated at every step. These processes included developing oral health messages on adequate dietary and oral hygiene practices as well as good dental clinic attendance. The messages were used to develop a folktale using improvisation circle method.&#x0D; RESULTS: A banner of 6 feet by 4 feet containing graphically designed illustrations (comic strips) of the traditional folktale was developed. The message of which was basically diet, oral hygiene and dental clinic attendance instructions aimed at improving the attitude and practice of primary school pupils in Ibadan to oral health. The folktale was primarily developed in English language, the official language in Nigeria, then translated to Yoruba, the indigenous language of the people of Ibadan. Many skills such as team-building, effective communication and leadership were developed from the many phases and meetings required in the development of the folktale.&#x0D; CONCLUSIONS: The early years are the formative years. Hence developing a tool to improve the oral health education of children using traditional folktale is a valuable and culturally advantageous project which has substantial future potentials.

Trends inprevalence, treatment use, anddisease burden inpatients with eosinophilic granulomatosis with polyangiitis inJapan: Real-world database analysis.

We report the prevalence of eosinophilic granulomatosis with polyangiitis (EGPA) and describe oral corticosteroid (OCS) use and disease burden before and after the mepolizumab approval in 2018 for EGPA in Japan. Two retrospective studies (GSK IDs: 218083 and 218084) used two databases: (1) the JMDC insurer database (Japanese health insurer claims) was used to report annual EGPA prevalence and OCS use in mepolizumab-treated patients and (2) Medical Data Vision database was used to report annual treatment use, OCS dose, relapses, and healthcare resource utilization in patients with EGPA. EGPA prevalence (95% confidence interval) increased from 4.2 (0.1, 23.4) in 2005 to 58.6 (53.2, 64.5) per 1,000,000 in 2020. Median OCS dose (mg/day) decreased from a range of 4.8-7.7 during 2010-2017 to 4.5-4.8 during 2018-2020 (lowest dose in 2020). The proportion of patients with prednisolone-equivalent daily OCS dose >10 mg decreased from 2017 (11.9%) to 2020 (10.3%), while the median dose halved. The proportion of patients with EGPA relapses (64.3% to 41.6%) and hospitalization (27.8% to 23.6%) decreased from 2010 to 2020. EGPA prevalence increased between 2005 and 2020. With the introduction of mepolizumab for EGPA in 2018, real-world OCS use, relapses, and healthcare resource utilization decreased.

Oral health status, treatment needs, and patterns of utilization of dental services among village volunteers in Andhra Pradesh: A cross-sectional multi-stage cluster survey.

Community health depends on the leadership duties of a diverse population, such as village volunteers. Hence, a study was conducted to assess oral health status, treatment needs, and patterns of utilization of dental services among village volunteers in Andhra Pradesh state. A cross-sectional study was conducted among 400 village volunteers in Andhra Pradesh state, India. A multi-stage cluster sampling procedure was employed in sample selection. A questionnaire was used to review the pattern of utilization of dental services. World Health Organization Oral Health assessment form 1997 was used to evaluate oral health status and treatment needs. Data collected were analyzed using IBM SPSS Statistics for Windows, Version 25.0. Descriptive statistics were done. Out of 400, 18% had never visited the dental clinic in their lifetime. The majority (33.5%) considered that dental problems were not a serious concern. Dental caries was seen in 69.5%, and 78.5% were presented with periodontal conditions. About 19.8% and 24.3% had crowding and spacing in incisal segments, respectively. The prevalence of oral mucosal disorders and dental fluorosis was 4.25% and 8.75%, respectively. Overall, 94% of the study participants needed dental treatment for various reasons. This study provides sufficient evidence to conclude that this population's oral health was poor, with increasing unmet dental treatment needs. Selected interventions and strategies should focus on these factors to decrease the burden of oral diseases among village volunteers.

Descriptive Study of Oral Health in an Indigenous Child Population of Baka Pygmies in Cameroon.

Indigenous populations around the world experience a disproportionate burden of oral diseases and health conditions. These inequalities are likely due to a complex web of socioeconomic, cultural, and health determinants. The Baka pygmies of southern Cameroon find themselves in this context of an indigenous population with health inequities. The purpose of this study was to describe the oral health status, diet, hygiene habits, and access to health services of the Baka pygmy children, from which different care needs will emerge in order to develop health strategies. A descriptive cross-sectional study was conducted in 22 Baka pygmy camps randomly selected. The study population consisted of children aged 5-6 years and 11-12 years chosen by a consecutive sampling technique. The examination was performed using a data sheet based on World Health Organization (WHO) criteria and recommendations which consisted of an oral health questionnaire for children and an oral health assessment form for children. A total of 120 children participated in the study. Extraoral examination of the study population revealed the presence of noma (1%) in the age range of 5-6 years. A total of 2713 teeth were examined, and the DMFT/dft index of the sample was 0.71 with a predominant caries component. The periodontal status showed 87% bleeding on probing. Seven percent of the sample presented a need for immediate urgent treatment due to pain and/or infection. Eighty-seven percent of the sample reported never having been examined by a dentist. The examination and oral care they received was only from nongovernmental organizations (NGOs). The conclusion of this descriptive study is that the precarious oral health situation of pygmy children combined with the absence of care services in general for the Baka pygmies generate a situation of great vulnerability.

Proteomic and single-cell analysis shed new light on the anti-inflammatory role of interferonβ in chronic periodontitis.

Periodontitis, a condition that results in periodontal attachment loss and alveolar bone resorption, contributes to the global burden of oral disease. The underlying mechanism of periodontitis involves the dysbiosis and dyshomeostasis between host and oral microbes, among which the macrophage is one of the major innate immune cell players, producing interferon β (IFNβ) in response to bacterial infection. The objective of this research was to examine the interaction of macrophages with periodontitis and the role and mechanism of IFNβ on macrophages. IFNβ has been shown to have the potential to induce the differentiation of M1 to M2 macrophages, which are stimulated by low levels of lipopolysaccharide (LPS). Additionally, IFNβ has been demonstrated to promote the production of ISG15 by macrophages, which leads to the inhibition of the innate immune response. Moreover, our investigation revealed that IFNβ has the potential to augment the secretion of ISG15 and its downstream cytokine, IL10, in LPS-stimulated macrophages. Single-cell analysis was conducted on the gingival tissues of patients with periodontitis, which revealed a higher proportion of macrophages in the periodontitis-diseased tissue and increased expression of IFNβ, ISG15, and IL10. Gene Set Enrichment Analysis indicated that bacterial infection was associated with upregulation of IFNβ, ISG15, and IL10. Notably, only IL10 has been linked to immunosuppression, indicating that the IFNβ-ISG15-IL10 axis might promote an anti-inflammatory response in periodontitis through IL10 expression. It is also found that macrophage phenotype transitions in periodontitis involve the release of higher levels of IFNβ, ISG15, and IL10 by the anti-inflammatory M2 macrophage phenotype compared to the pro-inflammatory M1 phenotype and myeloid-derived suppressor cells (MDSCs). This implies that the IFNβ-induced production of IL10 might be linked to the M2 macrophage phenotype. Furthermore, cell communication analysis demonstrated that IL10 can promote fibroblast proliferation in periodontal tissues via STAT3 signaling.

Current status of geriatric dentistry education in selected dental schools in Latin America and the Caribbean.

Latin American and Carribean (LAC) are currently experiencing a rapid aging of their population, coupled with a significant burden of oral diseases. Despites this, there is a scarcity of evidence regarding the manner in wich geriatric dentistry is being taught in dental schools across LAC. So, the objective of this study is to investigate the current status of geriatric dentistry education at undergraduate and postgraduate levels in selected LAC dental schools. An electronic questionnaire was developed and emailed to all 539 dental schools in 19 LAC countries. The questionnaire recorded activity levels, contents and methodology of geriatric dentistry education as part of dental degree programmes. Reminders by email and telephone calls were used to encourage non-responders to complete the questionnaire. In total, 317 schools from 17 countries responded to the questionnaire (response rate: 58.8%). Geriatric dentistry was taught in 54.6% of the schools at the undergraduate level and in 6.9% at the postgraduate level. Thirty two percent of the schools had a programme director trained in geriatric dentistry. Geriatric dentistry was taught as an independent course in 14.5% of the schools. Dry mouth, periodontal disease, denture-related conditions and prosthodontic management, oral mucosal disease and age-related changes of the orofacial complex were the most frequently covered topics. Clinical teaching of geriatric dentistry was reported by 26.5% of the schools, with 38.0% providing clinical training in outreach facilities. Geriatric dentistry education remains incipient in LAC, with only one in every four dental school offering it as a standalone course. There is an urgent need to further develop geriatric dentistry education in the continent, including further research to develop a minimum geriatric dentistry curriculum.

Oral Health Literacy Levels of Nursing Professionals and Effectiveness of Integrating Oral Health Training into Nursing Curricula: A Systematic Review

This systematic review assessed the evidence for the oral health literacy levels (i.e., knowledge, attitudes, barriers, oral care and practices, and trainings and resources) of nursing professionals and the effectiveness of integrating oral health training into nursing training. Four electronic databases were searched; however, for relevance, only evidence published between 2013 and 2023 was considered. Overall, 70 studies that focused on five key themes, namely, (i) knowledge of oral healthcare among nurses; (ii) attitudes of nurses towards oral healthcare; (iii) barriers to oral healthcare promotion; (iv) oral care and practices; and (v) trainings and resources to promote oral healthcare, were retrieved. Nurses were found to have a lack of or suboptimal of knowledge regarding oral healthcare. Moreover, their attitudes and practices related to the provision of oral healthcare varied substantially. Key barriers that impeded oral healthcare promotion included a lack of knowledge, awareness, education, skills, and training. Integrating oral health training was considered effective for improving oral health literacy and nurses emphasized the inclusion of such training into their curricula for improving oral healthcare. In summary, nurses have an important role to play in promoting oral health. Furthermore, integration of oral health training into nursing curricula could be a feasible approach to improve the oral health literacy of nurses and reduce the burden of oral disease.

Disease burden and prediction of oral cancer attributable to smoking in China from 1990 to 2019

Objective: To analyze the trend of disease burden of oral cancer attributable to smoking in China from 1990 to 2019, and predict the mortality trend of oral cancer from 2020 to 2034, providing scientific basis for formulating targeted oral cancer prevention and treatment strategy to achieve the goal of "Healthy China 2030". Methods: Using partial data on the global burden of disease in China in 2019, attributive death and disability adjusted life year (DALY) were used to describe. The trend of changes in the burden of oral cancer disease attributed to smoking was analyzed by using the Joinpoint regression model to estimate the annual average percentage change (AAPC) of age standardized mortality and DALY rates. Meanwhile, the Bayesian age-period- cohort model is used to predict oral cancer deaths and DALY trends attributed to smoking over the next 15 years. Results: The age-standardized mortality rate and DALY rate in China from 1990 to 2019 showed an overall upward trend, with an average annual increase of 1.49% (95%CI: 1.34%-1.65%, P<0.001) and 1.41% (95%CI: 1.24%-1.59%, P<0.001) respectively, higher than around the earth and in regions with different socio-demographic index (SDI). In 2019, 46.74% (10 584/22 642) of oral cancer deaths in China were attributed to smoking. Compared to 1990, the number of attributed deaths in 2019 increased by 293.75% (7 896/2 688), while DALY increased by 257.97% (189 039/73 280). Moreover, the growth rates of attributed deaths and DALY in males [304.95% (7 584/2 487) and 265.60% (183 349/69 033), respectively] were significantly higher than those in females [154.73% (311/201) and 133.95% (5 690/4 248), respectively] (P<0.001). The age group results showed that the proportion of deaths and DALY gradually transitioned towards the elderly (>60 years old). The expected number of deaths would increase from 10 731 in 2020 to 14 125 in 2034, with a rise of 31.63% (3 394/10 731). Simultaneously, DALY would increase from 267 064 person years in 2020 to 326 634 person years in 2034, with a rise of 22.31% (59 570/267 064). Conclusions: From 1990 to 2019, the burden of oral cancer diseases attributed to smoking in China showed an increasing trend, with a higher growth rates than in the global and different SDI regions. There were differences in gender and age, and the burden of oral cancer diseases attributed to smoking in China would continue to increase in the next 15 years. It is necessary to educate on the adverse effects of tobacco consumption and to conduct vigilant oral self-examination among high-risk groups to help early detection and intervention at the same time.

Projecting the burden of dental caries and periodontal diseases among the adult population in the United Kingdom using a multi-state population model.

With the aging United Kingdom population, oral diseases are expected to increase. Exploring credible projections is fundamental to understanding the likely impact of emerging population-level interventions on oral disease burden. This study aims at providing a credible, evidence-based projection of the adult population in the United Kingdom with dental caries and periodontal diseases. We developed a multi-state population model using system dynamics that disaggregates the adult population in the United Kingdom into different oral health states. The caries population was divided into three states: no caries, treated caries, and untreated caries. The periodontal disease population was disaggregated into no periodontal disease, pocketing between 4 and < 6 mm, 6 and < 9 mm, and 9 mm or more. Data from the 2009 dental health survey in the United Kingdom was used to estimate age and gender-specific prevalence rates as input to the multi-state population model. Of the population 16 years and older, the number with carious teeth is projected to decrease from 15.742 million in the year 2020 to 15.504 million by the year 2050, representing a decrease of 1.5%. For individuals with carious teeth, the older adult population is estimated to constitute 62.06% by 2050 and is projected to increase 89.4% from 5.079 million in 2020 to 9.623 million by 2050. The adult population with periodontal pocketing is estimated to increase from 25.751 million in 2020 to 27.980 million by 2050, while those with periodontal loss of attachment are projected to increase from 18.667 million in 2020 to 20.898 million by 2050. The burden of carious teeth and periodontal diseases is anticipated to shift from the adult population (16-59 years) to the older adult population. The older adult population with carious teeth is estimated to rise from 32.26% in 2020 to 62.06% by 2050, while that for periodontal disease is expected to increase from 42.44% in 2020 to 54.57% by 2050. This model provides evidence-based plausible future demand for oral health conditions, allowing policymakers to plan for oral health capacity to address growing needs. Because of the significant delay involved in educating and training oral health personnel, such projections offer policymakers the opportunity to be proactive in planning for future capacity needs instead of being reactive.

Children's Oral Health Initiative: workers' perspectives on its impact in First Nations communities.

Since 2004, the Children's Oral Health Initiative (COHI) has been working in many First Nations and Inuit communities in Canada to address oral health disparities, specifically early childhood caries (ECC). The COHI community-based approach improves early childhood oral health (ECOH) by balancing prevention with minimally invasive dentistry. The goal is to reduce the burden of oral disease, mainly by minimizing the need for surgery. We investigated program success in First Nations communities in the province of Manitoba, from the perspective of COHI staff. First Nations community-based dental therapists and dental worker aides participated in three focus groups and an in-depth semistructured interview. The collected data were thematically analyzed. Data from 22 participants yielded converging and practitioner-specific themes. Participants reported that dental therapists and dental worker aides provide access to basic oral care in their communities including oral health assessments, teeth cleaning, fluoride varnish applications and sealants. The participants agreed that education, information sharing and culturally appropriate parental engagement are crucial for continuous support and capacity building in the community programs. Low enrolment, difficulty accessing homes and getting consent, limited human resources as well as lack of educational opportunities for dental worker aides were identified challenges. Overall, the participants reported that the COHI program positively contributes to ECOH in First Nations communities. However, increased community-based training for dental workers, community awareness about the program, and engagement of parents to facilitate culturally appropriate programming and consent processes are critical to improving program outcomes.
