Objective: To assess dental utilization of resettled adult refugees in Washington (WA) state and the demographic factors associated with dental utilization.

Methods: Data were collected between January 1, 2015, and December 31, 2015 for newly arrived adult refugees (>21 years) enrolled in Washington State dental Medicaid program. Three state agencies provided enrollment and claims data that included demographic information as well as number and types of dental claims, and time to first dental claim for the newly resettled adult refugee population.

Results: A total of 1294 adult refugees resettled in WA State in 2015. Approximately, 67% were aged 21-39 years and 32.4% White race and 93.9% without any disability. Over half (57%) of adult refugees had at least one dental claim within 12 months, and the median time to first dental utilization was 4.1 months [IQR:2.4-6.8]. Black refugees had a 74% greater chance of a first dental claim within 12 months of resettlement compared to White refugees (p < .001), and people from countries with high volume of refugees also had a 31% greater chance than those from countries with low volume of refugees (p = .005).

Conclusions: Over half of all the adult refugees resettled in WA utilized dental services within 12 months of arrival. Understanding the mosaic of demographic backgrounds of newly resettled refugees in any given state will improve early utilization of dental care needs and therefore improve their oral health.

Childhood primary dentition caries prevalence and experience is higher among Qatari than non-Qatari nationality children in Qatar but only this bivariate association has been described.

Objectives: There were two objectives. First, to understand the variation of primary dentition caries among 4- to 8-year-old children in Qatar across nationality classified into four groups, and second, to explore whether the association persisted in the presence of socio-demographic and behavioural indicators.

Methods: The study used data from the Qatar Child Oral Health Survey 2017 (QCOHS 2017). Detailed information was collected through a parental dual-language questionnaire and an oral epidemiological examination conducted by calibrated dentist examiners. Children in 20 kindergartens and 40 schools across Qatar were recruited. Data were weighted to represent the Qatar child population.

Results: Overall, 1154 children aged 4-8 years old (48.9% female, 51.1% male) participated. Qatari children made up 26.3%, Non-Qatari (N-Q) Arabic children 44.2% N-Q Indian sub-continent 16.4% and N-Q Other 13.1%. There were no significant differences by nationality for age or sex, but differences existed for kindergarten/school type and parents' highest level of education. Among behavioural indicators, Qatari and N-Q Arabic children began toothbrushing later, and more N-Q Other children brushed 2+ times a day and had made a check-up visit in the last 12 months. More Qatari children were in the highest tertial for sugar intake and drank bottled water with no fluoride. All N-Q children had a significantly lower prevalence and experience of caries. The means ratio (95% CI) for N-Q Arabic (0.78; 0.65-0.94), Indian (0.58; 0.46-0.72) and other children (0.61; 0.42-0.88) were all significant against Qatari nationality children. Multivariable models showed an attenuation of the association with caries with the means ratio for N-Q Arabic (0.92; 0.73-1.16), Indian (0.79; 0.57-1.11) and other children (0.94; 0.61-1.44) being non-significant compared to Qatari nationality children. The variables which were significantly associated with caries were parental education, toothbrushing frequency, sugar intake and check-up visiting in the last 12 months in the multivariable models.

Conclusions: Primary dentition caries in children resident in Qatar differed by nationality. The association of primary dentition caries with nationality was markedly attenuated and non-significant in the presence of socio-demographic and behavioural variables, pointing towards the importance of these variables as the pathways to improving primary dentition caries prevalence and experience of children in Qatar.

Objective: To identify vulnerable areas and populations with limited access to dental care in Virginia, the study aimed (1) to calculate travel time and accessibility scores to dental care in Virginia using a transit-based accessibility model for all dental clinics and dental clinics participating in the Medicaid dental program and (2) to estimate factors associated with accessibility to dental clinics participating in the Medicaid dental program in Virginia.

Methods: The study used building footprints as origins of transit trips to dental care services (or destinations). The study then computed transit-based origin-destination travel time matrices based on the detailed trip information, including in-vehicle and out-of-vehicle travel time. Accessibility scores were calculated by counting the number of dental clinics that can be reached within 60 min. Regression analysis was used to measure factors associated with accessibility scores to dental clinics participating in Medicaid.

Results: Residents in smaller regions spent longer travel time to dental clinics by public transit compared with those who resided in larger regions. Medicaid participants also faced longer travel time compared with the general population. Residents spent more than three-fourths of the time waiting for public transit and walking to clinics regardless of where they live and what type of insurance they have. Associations between sociodemographic factors and accessibility scores to dental clinics participating in the Medicaid dental program varied across regions.

Conclusions: Disparities in dental care accessibility exist depending on the size of regions and Medicaid participation in Virginia. The disparities in transit-based access to dental clinics and a disproportionate amount of time spent waiting for public transit and walking to dental clinics could be improved through tailored interventions taking into account the sociodemographic and geographic characteristics of each region.

Objective: To systematically assess current evidence on the extent to which social relationships are associated with tooth loss in adults aged 60 years and older.

Methods: A systematic literature search was conducted on PubMed, Embase, Web of Science, CINAHL and The Cochrane Library databases to identify relevant studies published from 1966 up to March 2024. Cross-sectional or cohort studies investigating the association between structural, functional and/or combined (structural and functional) components of social relationships and the number of remaining teeth or edentulism among community-dwelling or institutionalised older adults were included. Data were extracted on participants' and study characteristics, including study design, the type of measures used to assess social relationships (structural, functional, and combined), outcome measures and association estimates. The quality of the studies was assessed using the Newcastle-Ottawa Scale (NOS) for cohort studies and the adapted NOS for cross-sectional studies. The reported association between social relationships and the number of remaining teeth or edentulism was summarised using meta-analysis with robust variance estimation.

Results: Twenty studies were included in the review and 12 studies (125 553 participants) in the meta-analysis. Across the 12 studies, the average odds ratio (95% confidence interval) was 1.15 (1.01-1.32), indicating a 15% higher likelihood of having a lower number of teeth or edentulism for those with weaker social relationships. The GRADE certainty of the body of evidence was low.

Conclusions: Weak social relationships were associated with a lower number of teeth or edentulism in older adults. Our findings may inform potential public health approaches that target and modify social relationships to prevent and address older adults' oral diseases. Still, the directionality and the underlying mechanisms connecting social relationships and tooth loss need to be further explored by longitudinal studies with follow-up long enough for oral health outcomes or changes in social relationships to occur.

Objectives: The objectives were to: (i) assess the accuracy of dental data for adults obtained from the Swedish Quality Register on Caries and Periodontitis (SKaPa); (ii) explore whether Latent Class Analysis (LCA) can identify groups of people based on caries data; and (iii) characterise the dental, medical and behavioural characteristics of people in the LCA-derived classes.

Methods: Caries data from the SKaPa register were compared with clinical data collected by five experienced dentists in a nested subgroup of the Malmö Offspring Study (MOS), namely the Malmö Offspring Dental Study (MODS) (n = 724) for validation. Dental data from SKaPa were then used to classify 61 984 adult participants of the Västerbotten Intervention Programme (VIP) into five classes using LCA and DMFS-based quintile ranking, respectively. Dental status (including caries progression over 5 years), medical, anthropometric and behavioural characteristics were compared between the groups. Analyses were replicated in 2767 adults in the MOS.

Results: DMFS-scores and number of teeth recorded within -2 to +2 years showed excellent agreement between the SKaPa and reference data with intra-class correlations > 0.90. The five LCA classes differed in mean DMFS from 10.0 to 94.4. There were strong associations between LCA class and health, and health and behavioural measures respectively, including some associations that were not detected using DMFS-ranked quintile groups. LCA class was associated with incremental change in DMFS, DFS, and number of teeth. The results in the MOS cohort were consistent with the results in the VIP cohort.

Conclusions: Dental data for adults from the SKaPa registry were considered accurate within 2 years of recording. The LCA approach can classify participants into caries subtypes based on dental charting. These groups differ in health and behavioural characteristics and future caries increment. The LCA approach may capture some information that is missing from DMFS-ranked quintile groups, but is also heavily influenced by total DMFS, meaning that applying LCA in cumulative, highly age-determined diseases, such as caries, is a challenge.

Background: Antimicrobial resistance is a significant threat to global health. Antimicrobial stewardship is reducing inappropriate antimicrobial prescribing to counter it. Dentists prescribe ~10% of all antibiotics worldwide, yet up to 90% of antibiotic prescriptions by dentists are inappropriate. The aim of this systematic review was to update a 2017 review evaluating the effects of antibiotic stewardship interventions in dental settings, using the international consensus on core outcomes for dental antibiotic stewardship.

Methods: Systematic database searches were undertaken in April 2023, of the: Cochrane Oral Health Group Trials Register, Cochrane Central Register of Controlled Trials, MEDLINE via OVID, EMBASE via OVID, Dentistry and Oral Sciences Source, the US National Institutes of Health Trials Register, the World Health Organisation International Clinical Trials Registry Platform and the ISRCTN registry databases. Randomised controlled trials (or non-randomised studies with clearly reported mechanism of group formation and inclusion criteria) of interventions to optimise and/or reduce dental antibiotic prescribing were eligible for inclusion. Two authors independently screened for eligible studies. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool, certainty of evidence assessed using GRADE. Meta-analysis was planned whether the results of studies reported similar outcomes, otherwise narrative synthesis was undertaken.

Results: Three eligible studies randomising 2148 participants were included. The interventions were combinations of education, audit and feedback and written behaviour change messages, guideline summary, practice visits and patient leaflets. None of the control groups received an intervention. All three included studies measured the quantity of antibiotics prescribed and two measured the appropriateness of prescribing. None measured patient-reported or adverse outcomes. Two included studies were assessed as 'high risk' and one with 'low risk' of bias. There was high-certainty evidence that audit and personalised feedback with individualised behaviour change messages can be effective. Evidence for in-person education was low-certainty. Guideline dissemination alone was ineffective at improving antibiotic prescribing. Due to different outcomes reported, meta-analysis was inappropriate.

Conclusion: Although various dental antibiotic stewardship interventions have been reported in the literature, none provided high-certainty evidence of effectiveness and only three have been evaluated using a randomised design. To strengthen the body of evidence, well-powered, robust, randomised controlled trials are required, with adequate follow-up, reporting the internationally-agreed core outcomes and including a parallel process evaluation is recommended.

Objectives: To evaluate the relationships of cognitive function and care dependency with oral health in a Norwegian older adult population.

Methods: This cross-sectional study included 2623 participants aged 70 and older from the fourth wave of the Trøndelag health study (HUNT4 70+) and the city of Trondheim (Trondheim 70+). Neurocognitive disorders (NCDs) were diagnosed by clinical experts according to the DSM-5 framework. Care dependency referred to nursing home residency. Oral health was assessed by using the Revised Oral Assessment Guide-Jönköping (ROAG-J). Individuals were considered as 'having oral problem' if the score was two or three in at least one of the nine ROAG-J items. Poisson regression was used to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs).

Results: The prevalence of having oral problems was 19% higher in participants with NCDs than those with normal cognitive function after adjusting for potential confounders (PR 1.19, 95% CI: 1.09-1.29). Further analysis showed a higher prevalence of having oral problems for home dwellers with NCDs (PR 1.23, 95% CI: 1.13-1.33) and nursing home residents (PR 1.32, 95% CI: 1.20-1.45) compared to home dwellers with normal cognitive function.

Conclusions: NCDs were associated with an increased prevalence of oral problems in this Norwegian older adult population. The study suggests the need for increasing oral care for home dwellers with NCDs and nursing home residents.

Objectives: This qualitative study aimed to explore the experience and perception of the mouth, oral health, functioning and the social environment amongst adults with disabilities and complex health conditions.

Methods: Purposive sampling using the maximum variation strategy was performed to select participants with a wide range of experiences in terms of demographics, disability and health conditions. Consent was sought, and semi-structured interviews were conducted, recorded and transcribed verbatim. Within the interpretivist tradition, a phenomenological approach was used to describe the lived, contextualised experience of people in relation to their mouths, as described by participants. Thematic analysis was undertaken.

Results: Eighteen participants with disabilities and complex health conditions were interviewed. Twelve individuals had an intellectual disability. Three main themes were identified: perception of the mouth and oral health; symptomatic perceptions and responses to oral health problems; and inter-relationships between the mouth, oral health and the socio-medical environment. The mouth had a central place in the lives of the participants, but its importance was only recognised when oral health problems interfered with daily life, function, social relationships, family life or autonomy. Certain social determinants of health were identified: social exclusion, financial insecurity, lack of autonomy, nutrition and negotiation of services. Oral problems were perceived as an additional burden to those with disabilities or complex health conditions.

Conclusion: This study provided insight into the daily lives of adults with disabilities and complex health conditions. It helps to fill the gaps in the existing literature regarding the perceptions of the mouth and oral health, connecting oral function, general health and social environment for this population.

Trial registration: This study was registered into ClinicalTrials.gov (NCT04815434).

Objectives: To investigate whether timing, accumulation and trajectories of poverty are associated with dental caries in young adolescents.

Methods: The study was conducted within the Generation R Study, which is an ongoing population-based prospective cohort study conducted in Rotterdam, the Netherlands. This study included 2653 children. Information about household income and number of children and adults living in a household at six time points from pregnancy to 13 years old was retrieved from parental questionnaires to construct the poverty variable. Dental caries was assessed with the decayed, missing and filled teeth index through intraoral photographs at the age of 13 years. Sociodemographic and oral health-related characteristics were included as possible confounders. The association between poverty and dental caries was analysed on the basis of the three lifecourse theories, that is, critical period, cumulative risk and social mobility model. For the latter, we used latent class growth analysis (LCGA) to identify poverty trajectories over time. Next, the associations were studied with Hurdle Negative Binomial Models.

Results: Poverty at birth and intermittent poverty up to the age of 13 were significantly associated with dental caries at 13 years of age (OR 1.41, 95% CI 1.01-1.99; OR 1.36, 95% CI 1.01-1.83 respectively) and with an increased mean number of decayed teeth by 34% (95% CI 1.02-1.76; 95% CI 1.05-1.71, respectively). LCGA showed four trajectories for the probabilities of poverty. All trajectories were significantly associated with dental caries at 13 years of age, with the 'downward mobility' trajectory showing the strongest association with dental caries (OR 1.55, 95% CI 1.05-2.29) and an increasing mean number of decayed teeth by 58% (95% CI 1.18-2.12) than the 'stable absent' trajectory.

Conclusion: Poverty at birth, intermittent poverty and downward poverty trajectory were associated with higher odds and higher mean number of decayed teeth at 13 years of age. The three lifecourse models influenced dental caries status during adolescence, hence strategies and policies targeted to improve socioeconomic conditions on deprived children should be implemented.

Objective: Causal analysis including causal inference and causal mediation is pivotal to inform effective interventions. In modern epidemilogy, causal analysis involves four key steps: formulating causal questions, employing directed acyclic graphs (DAGs), conducting data management and selecting statistical strategies. Our objective was to conduct a scoping review to assess how longitudinal observational studies (LOSs) in dental field have integrated these four steps to contribute leverage evidence that inform oral public health interventions.

Methods: LOSs focusing on determinants of dental caries published from 2012 to 2024 were systematically retrieved from five major databases. The Joanna Briggs Institute-scoping review guidance and the Covidence application were employed to identify eligible LOSs for being reviewed.

Results: Out of the 85 eligible LOSs, none formulated causal hypothesis by applying 'what if' question or investigated mediation across three levels of the determinants of oral health. A minority (18 studies, ~21.2%) employed DAGs to visualise relationships among study variables, while only one third (33 studies, ~39%) clearly defined confounders. The majority (64 studies, ~75%) incorporated a time-varying feature of their data, yet only a few (11 studies) fully leveraged this advanced aspect. Among these studies that fully utilised time-varying data, more than half encountered challenges in employing robust statistics to address confounders arising from such data dynamics.

Conclusions: Dental LOSs have, to date, mostly focused on investigating associations over causality, often neglecting the four-step causal analysis and not fully utilising time-varying data. Researchers necessitate to shift their focus to causal inference and prioritise building capacity in causal analysis with a consistent four-step approach to advance the field. Studies exploring mechanisms linking determinants of dental caries across levels and leveraging time-varying data are strongly encouraged.
