ABSTRACT
AIM: This study investigated the association between the triglyceride-glucose (TyG) index, a surrogate marker of insulin resistance, and moderate/severe periodontitis and the role of blood pressure as a mediator in this association. A second aim was to assess the role of cardiometabolic conditions such as obesity, hypertension, and dyslipidemia as potential effect modifiers. METHODS: Data from 5733 US adults aged 30-64 years and with complete periodontal examination were analyzed (NHANES 2011-2014). Participants were classified as having moderate/severe periodontitis or mild/no periodontitis according to the CDC/AAP criteria as the outcome. The exposure was the TyG index, while both systolic (SBP), and diastolic (DBP) blood pressure were tested as mediators using parametric g-formula. Analyses were adjusted for relevant confounders, namely, age, sex, ethnicity, poverty-income ratio, and smoking, using inverse probability treatment weighting. Obesity status (based on a body mass index ≥30 kg/m2), self-report of hypertension and dyslipidemia (calculated based on the thresholds provided by National Cholesterol Education Program-Adult Treatment Panel-III) were tested as effect modifiers. RESULTS: The findings showed the TyG index to be associated with increased odds of moderate/severe periodontitis [odds ratio (OR), 95% confidence interval (CI) = 1.17 (1.11-1.23)], with 50% of the total effect mediated by SBP. Stratified analysis showed a stronger association in individuals with obesity, hypertension, and dyslipidemia compared to those without these conditions. However, in those taking anti-hypertensive medications, the association was partially mitigated. Sensitivity analysis using imputed data showed consistent results. CONCLUSION: The TyG index was associated with increased odds of moderate/severe periodontitis, especially in individuals with obesity, hypertension, and dyslipidemia. SBP levels partially mediated this association.
ABSTRACT
OBJECTIVE: We investigated the bidirectional relationship between rheumatoid arthritis (RA) and periodontitis and their cross-sectional association using national administrative health care data. METHODS: The sample included 3,308,903 individuals aged 20 to 79 years who resided in Denmark in 2000 and had remained free of RA and periodontitis in the previous 10 years. RA and periodontitis were defined using diagnosis and treatment codes. Marginal structural survival models were employed to estimate the effects of RA on periodontitis incidence and vice versa from 2000 to 2017. Using a cross-sectional sample of 2,574,536 individuals from 2017, the association of periodontitis with RA was investigated using regression analyses and probabilistic quantitative bias analyses, simulating RA and periodontitis misclassification and unmeasured confounding of smoking. RESULTS: Between 2000 and 2017, 20,348 individuals developed RA and 740,799 developed periodontitis. The estimated hazard ratio (HR) for the effect of periodontitis on incident RA was 1.05 (95% confidence interval [CI] 0.88-1.25), resulting in a restricted mean survival time difference of one day. The HR for the effect of RA on incident periodontitis was 0.84 (95% CI 0.80-0.88), corresponding to a restricted mean survival time difference of 151 days. Cross-sectionally, the unadjusted prevalence ratio for the association was 1.15 (95% CI 1.11-1.19), whereas the estimate adjusted for measured and simulated confounding was practically null (0.99, 95% simulation interval 0.93-1.04). CONCLUSION: These findings challenge previously reported bidirectional relationships between periodontitis and RA, pointing to potential residual confounding as an important link and prompting reconsideration of the biologic plausibility and clinical significance of these associations.
ABSTRACT
AIM: To explore the association between periodontitis and olfactory disorders. METHODS: Clinical data were collected from 198 individuals between the ages of 18 and 60 years living in Denmark. The exposure was periodontitis, and the outcome was olfactory function (Threshold, Discrimination, Identification - TDI score), both measured clinically. Covariates included sex, age, education level, income, usage of nasal spray, tongue coating, halitosis, xerostomia, smoking, and history of COVID-19. Structural equation modeling was used to estimate the association between periodontitis and olfactory function. Periodontitis was defined using the AAP/EFP classification and dichotomized into "no" (healthy subjects) and "yes" (Stages I, II, and III). Olfactory function was treated as a one-factor latent variable, including the different olfactory scores. In addition, extra models were performed considering each olfactory component as a separate outcome and the TDI Global Score. RESULTS: The results showed that periodontitis was associated with a lower olfactory function [standardized coefficient (SC) -0.264, 95% CI -0.401, -0.118]. Additionally, periodontitis was also associated with a lower olfactory Threshold (odorant concentration required for detection) (SC -0.207, 95% CI -0.325, -0.089), Discrimination (ability to discriminate between odorants) (SC -0.149, 95% CI -0.270, -0.027), Identification (ability to identify odorants) scores (SC -0.161, 95% CI -0.277, -0.045), and TDI Global Score (SC -0.234, 95% CI -0.370, -0.099). CONCLUSIONS: This study suggests that periodontitis is associated with olfactory impairment.
ABSTRACT
OBJECTIVE: To analyze multiple-causal models, including socioeconomic, obesity, sugar consumption, alcohol smoking, caries, and periodontitis variables in pregnant women with early sugar exposure, obesity, and the Chronic Oral Disease Burden in their offspring around the first 1000 days of life. METHODS: The BRISA cohort study, Brazil, had two assessments: at the 22nd-25th gestational weeks and during the child's second year (n = 1141). We proposed a theoretical model exploring the association between socioeconomic and pregnancy factors (age, smoking, alcohol, sugars, obesity, periodontitis, and caries) and child's variables (sugars and overweight) with the outcome, Chronic Oral Disease Burden (latent variable deduced from visible plaque, gingivitis, and tooth decay), using structural equation modeling. RESULTS: Caries and periodontitis were correlated in pregnant women. Addictive behaviors in the gestational period were correlated. Obesity (Standardized coefficient - SC = 0.081; p = 0.047) and added sugar consumption (SC = 0.142; p = 0.041) were observed intergenerationally in the pregnant woman-child dyads. Sugar consumption by the children (SC = 0.210; p = 0.041) increased the Chronic Oral Disease Burden. CONCLUSIONS: Poor caries and periodontal indicators were correlated in pregnant women and their offspring. Obesity and sugar consumption act intergenerationally. Oral health in early life may change life trajectory since the worst oral conditions predict main NCDs.
ABSTRACT
Although self-reported health outcomes are of importance, attempts to validate a clinical applicable instrument (e.g., nomogram) combining sociodemographic and self-reported information on periodontitis have yet to be performed to identify periodontitis cases. Clinical and self-reported periodontitis, along with sociodemographic data, were collected from 197 adults. Akaike information criterion models were developed to identify periodontitis, and nomograms developed based on its regression coefficients. The discriminatory capability was evaluated by receiver-operating characteristic curves. Decision curve analysis was performed. Smoking [OR 3.69 (95%CI 1.89, 7.21)], poor/fair self-rated oral health [OR 6.62 (95%CI 3.23, 13.56)], previous periodontal treatment [OR 9.47 (95%CI 4.02, 22.25)], and tooth loss [OR 4.96 (95%CI 2.47, 9.97)], determined higher probability of having "Moderate/Severe Periodontitis". Age [OR 1.08 (95%CI 1.05, 1.12)], low educational level [OR 1.65 (95%CI 1.34, 2.23)], poor/fair self-rated oral health [OR 3.57 (95%CI 1.82, 6.99)], and previous periodontal treatment [OR 6.66 (95%CI 2.83, 15.68)] determined higher probability for "Any Periodontitis". Both nomograms showed excellent discriminatory capability (AUC of 0.83 (95%CI 0.75, 0.91) and 0.81 (95% CI 0.74, 0.88), good calibration, and slight overestimation of high risk and underestimation of low risk. Hence, our nomograms could help identify periodontitis among adults in Denmark.

OBJECTIVES: It is not clear if or how the incidence of systemic conditions like type 2 diabetes mellitus (DM2), rheumatoid arthritis (RA) or inflammatory bowel disease (IBD) affects dental service utilization. Using nationwide Danish register data, the aim of this study was to analyse the use of dental services 7 years before and after being diagnosed with DM2, RA or IBD between 1997 and 2011. METHODS: Information about incident DM2 was obtained from the National Diabetes Register, and incident RA and IBD were defined based on diagnosis codes of hospital contacts identified through the National Patient Register. Separately, for each of the three conditions, each individual with the incident condition was matched to one control individual based on age, gender, country of origin, municipality of residence, highest completed education, the main source of income and income using coarsened exact matching in the year of incidence. The use of dental services and treatments received within each calendar year from 7 years before to 7 years after getting the condition were analysed with generalized estimating equations. RESULTS: People with incident DM2 were less likely (by seven percentage points) to be dental service users within a year than people without incident DM2 for a period extending from up to 7 years prior to 7 years after the diagnosis. This difference even slightly increased after the diagnosis. Those with incident IBD exhibited a consistently but modestly higher proportion of dental service use (three percentage points) than those without incident IBD before and after the diagnosis. Differences in the use of services between those with or without incident RA were minor. For all three systemic diseases, detected differences mainly mirrored differences in the provision of supragingival scaling and restorative treatment. CONCLUSIONS: The findings suggest that the impact of these three systemic conditions on dental service use was minor.
ABSTRACT
AIM: To explore the association between oral conditions and their interaction with salt taste disability among American adults. METHODS: Data from the 2013-2014 NHANES cycle were used (n = 2373). The exposures were periodontitis, defined by the 2017 EFP-AAP classification, dental caries, missing teeth, and edentulism, as per the DMF-T index, and xerostomia. The outcome was salt taste disability, objectively assessed. Covariates included sex, age, educational level, poverty index, obesity, diabetes, smoking, alcohol consumption, and medications related to mouth dryness. Weighted multivariable logistic regression modeling was used to evaluate the relationship between oral conditions and their interaction and salt taste disability. RESULTS: Participants who reported xerostomia were more likely to have salt taste disability (OR 2.42; 95%CI 1.44-4.07), especially those older than 60 years (OR 3.63; 95%CI 1.72-7.63). Among participants aged 40-59, xerostomia increased the chance of salt taste disability; however, the confidence interval included the null value. The interactions between xerostomia and edentulism increased the chance of salt taste disability. CONCLUSION: Oral conditions seem to influence the ability to taste salt. Dental professionals may help identify individuals with taste alterations and raise their awareness of the risk of systemic diseases that require the reduction of salt intake.
ABSTRACT
BACKGROUND: Chewing disability is associated with impaired quality of life, potentially leading to depression, and cognitive impairment. Although the chewing-ability-cognition relationship has been explored, examining whether depression mediates this relationship remains unclear. We investigated the association between chewing disability and cognitive impairment development and a potential mediation via depression among older persons. METHODS: Older persons without cognitive impairment at baseline (nâ =â 973) from the 3 waves of the Panel on Health and Ageing of Singaporean Elderly were investigated. The outcome was incident cognitive impairment by the end of the study, while the exposure was chewing disability over the study period. Time-varying depression was the mediator. Time-fixed confounders included sex, ethnicity, education, marital status, living arrangement, and housing type, and time-varying confounders included age, smoking, cardiovascular diseases, diabetes, number of teeth, and denture wearing. We used marginal structural modeling to evaluate the effect of chewing disability on cognitive impairment development. RESULTS: After 6 years, 11% developed cognitive impairment, and chewing disability was reported by 33%. Chewing disability was associated with higher odds of developing cognitive impairment (OR 1.43, 95% CI: 1.09, 1.87), of which 85.3% was explained by the controlled direct effect of chewing disability, whereas the remaining 14.7% could be eliminated if there was no depression. CONCLUSIONS: Our findings indicate an association between chewing disability and cognitive impairment, while the role of depression could not be fully elucidated. Oral health should be incorporated as part of older persons' care for its potential to assess the risk for other systemic conditions.

AIM: Investigating the association between sugar-sweetened beverages (SSBs) and periodontitis and whether the awareness of diabetes modifies this relationship. MATERIALS AND METHODS: Cross-sectional analysis was conducted using the National Health and Nutrition Examination Survey (NHANES III) data involving US adults aged 30-50. Periodontitis was classified according to the Centers for Disease Control and Prevention and American Academy of Periodontology (CDC-AAP), and SSB consumption as dichotomous (<5 or ≥5, <7 or ≥7 and <14 or ≥14 times/week), ordinal and continuous variables. Confounders included family income poverty ratio, education, race/ethnicity, sex, age, food energy intake, smoking and alcohol. Odds ratios (ORs) were obtained by logistic regressions using inverse probability weighting. Effect modification analysis was performed considering self-reported diabetes. RESULTS: Among 4473 cases analysed, 198 self-reported diabetes. SSBs were associated with periodontitis when individuals consumed ≥5 (OR 1.64; 95% confidence interval [CI] = 1.30-2.06), ≥7 (OR 1.92; 95% CI = 1.50-2.46) and ≥14 (OR 2.19; 95% CI = 1.50-3.18) times/week. The combined effect of consuming SSBs (≥5 and ≥14 times/week) and self-reported diabetes had less impact than the cumulative effect. CONCLUSIONS: SSB consumption was associated with higher odds of periodontitis, and the estimates were reduced among those with awareness of diabetes.

OBJECTIVES: To examine trends in incidence and mortality and evaluate overall survival (OS) of oral cancer in Singapore between 1968 and 2017. METHODS: All diagnosed oral cancers by anatomical sites and population size were extracted from the Singapore Cancer Registry and the Department of Statistics Singapore. The trend of age-standardized incidence rate (ASIR) and mortality rate (ASMR) (per 100 000 person-years) of the lip, oral cavity and salivary gland cancers were evaluated by Prais-Winsten regressions for each ethnicity and gender. Kaplan-Meier curves were performed to evaluate the OS by anatomical sites in each age group by ethnicity and sex. RESULTS: Overall, 49, 3494 and 1066 people were diagnosed, and 28, 2310 and 476 died from lip, oral cavity and salivary gland cancers, respectively. The oral cavity cancer ASIR and ASMR reduced from 3.07 (1968-1972) to 2.01(2008-2012) and from 2.06 (1978-1982) to 1.21 (2013-2017) per 100 000 person-years, respectively, with both highest in Indians throughout the whole period. Male:Female ratio ranged from 3.43 (1973-1977) to 1.75 (2013-2017) and from 3.41 (1978-1982) to 2.40 (2013-2017) for ASIR and ASMR, respectively. However, both salivary gland cancer ASIR and ASMR increased from 0.50 (1968-1972) to 0.80 (2008-2012) and from 0.18 (1968-1982) to 0.42 (1988-1992) per 100 000 person-years, respectively, with both higher in males since 1993. Oral cavity cancer ASIR decreased for males aged ≥60, and Indian females ≥25, but increased among Chinese females aged ≥60. Oral cavity cancer ASMR decreased among Chinese aged 25-59, and among Malay males and Indian females. Salivary gland cancer ASIR increased among Chinese males aged ≥60 and Malay males aged 25-59; while ASMR increased among Chinese males aged ≥60. The median OS for oral cavity, lip and salivary gland cancers were 3.0, 9.3 and 18.1 years, respectively, with females surviving longer than males. CONCLUSIONS: Singapore has experienced a decline in the incidence and mortality of lip, oral cancer, an increase in in the incidence and mortality of salivary gland cancer, with an increase in the median overall survival rate. Monitoring the magnitude of oral cancer burden and the demographic, and temporal variations is necessary for tailoring health planning and setting priorities for future clinical care and research.

OBJECTIVES: To assess color change efficacy and the adverse effects of varied over-the-counter (OTC) bleaching protocols. METHODOLOGY: The study included randomized clinical trials evaluating color changes from OTC bleaching agents. Nine databases were searched, including the partial capture of the grey literature. The RoB2 tool analyzed the individual risk of bias in the studies. Frequentist network meta-analyses compared treatments through common comparators (∆Eab* and ∆SGU color changes, and tooth sensitivity), integrating direct and indirect estimates and using the mean and risk differences as effect measures with respective 95% confidence intervals. The GRADE approach assessed the certainty of the evidence. RESULTS: Overall, 37 remaining studies constituted the qualitative analysis, and ten composed the meta-analyses. The total sample included 1,932 individuals. ∆Eab* was significantly higher in groups 6% hydrogen peroxide (HP) strips (≥ 14 h). ∆SGU was significantly higher in groups at-home 10% carbamide peroxide (CP) (≥ 14 h), followed by 6% HP strips (≥ 14 h) and 3% HP strips (≥ 14 h). At-home 10% CP (7-13 h) and placebo showed lower risks of tooth sensitivity without significant differences between these treatments. CONCLUSION: Considering the low level of evidence, OTC products presented satisfactory short-term effects on tooth bleaching compared to the placebo, with little to no impact on dentin hypersensitivity and gingival irritation. CLINICAL RELEVANCE: OTC products are proving to be practical alternatives for tooth whitening. However, patients should be advised about the possible risks of carrying out such procedures without professional supervision.

OBJECTIVES: This cross-sectional school-based study explored the influence of malocclusion on temporomandibular disorders (TMD) pain complaints, and whether this association would be mediated by sleep bruxism in a representative sample of 7- to 8-year-old children. METHODS: Path analysis estimated direct, indirect, and total effects of occlusal features on sleep bruxism and TMD pain in 7- to 8-year-old children. Occlusal features were assessed with Dental Aesthetic Index (DAI), orofacial pain complaints using the TMD pain screener, possible sleep bruxism based on self-reports, and probable sleep bruxism based on self-reports combined with clinical findings. Structural equation modeling analyzed data with confounding factors. RESULTS: From 580 participants, possible sleep bruxism was observed in 136 children (31.5%), probable sleep bruxism in 30 children (6.7%), and TMD pain complaints in 78 children (13.8%). Malocclusion had no direct effect on either possible sleep bruxism [standardized coefficient (SC) 0.000; p = 0.992], or TMD pain complaints (SC - 0.01; p = 0.740). When probable sleep bruxism was set as the mediator of interest, malocclusion did not directly affect probable sleep bruxism (SC 0.01; p = 0.766), nor TMD pain complaints (SC - 0.02; p = 0.515). A direct effect of probable sleep bruxism on TMD pain complaints was observed with an SC of 0.60 (p < 0.001). However, in neither case, malocclusion indirectly affected TMD pain complaints via bruxism. CONCLUSION: Malocclusion in 7- to 8-year-old children did not directly influence possible or probable sleep bruxism or TMD pain complaints. Instead, probable sleep bruxism was strongly associated with TMD pain complaints. CLINICAL SIGNIFICANCE: The impact of occlusal features on TMD pain complaints and bruxism has been a long-standing controversy in dentistry. However, the scientific literature linking this association may be inconsistent, mainly due to biased sample selection methods with inadequate consideration of confounders. Further research should try to identify additional risk factors for TMD pain in addition to probable sleep bruxism in children.

BACKGROUND AND OBJECTIVES: Patients with dentofacial deformity (DFD) requiring orthognathic treatment have poor aesthetics, jaw function and psychological well-being, which potentially affect the quality of life. This study aimed to investigate the health-related general, oral and orthognathic quality of life, jaw function and sleep-disordered breathing at different stages of orthognathic surgical treatment. METHODS: A total of 120 consecutive patients with DFD were recruited and grouped as pre-orthodontic treatment (group 1), pre-surgery (group 2), 4 months post-surgery (group 3), 24 months post-surgery (group 4) and in addition 30 controls without DFD (group 0). Outcomes were assessed using general health Short Form Survey (SF-36), Oral Health Impact (OHIP-14), Orthognathic Quality of Life Questionnaire (OQLQ), STOP-Bang and Jaw Function Limitation Scale (JFLS) questionnaires. In addition, presence or absence of pain was recorded. Data were tested with analysis of variance, Kruskal-Wallis test, Tukey post hoc test and structural equation modelling (SEM). RESULTS: Results revealed SF-36 (p = .814) and STOP-Bang (p = .143) total scores did not differ between control and treatment groups. In contrast, OHIP-14, OQLQ and JFLS total scores differed between groups (p = .001). Higher scores were observed in groups 1 (p = .001), 2 (p = .001) and 3 (p = .041) compared to group 0, indicating poor oral health in patients with DFD. Importantly, in group 4, oral health-related quality of life was better, and OHIP-14 (p = .936) and JFLS (p = .572) scores did not differ from controls. OQLQ scores of group 4 were significantly lower than group 1 (p = .001) but higher than group 0 (p = .013). SEM results revealed a significant negative associations of pain with JFLS and OQLQ; OHIP-14 with OQLQ; OHIP-14 with SF-36; and finally STOP-Bang with SF-36. Positive associations were observed between JFLS and OHIP-14; OHIP-14 and OQLQ. CONCLUSION: Oral health-related quality of life and jaw function appears to be improved 24 months after orthognathic surgery. Pain and limitation in jaw function had a negative association with health-related quality of life.

OBJECTIVES: To examine the extent to which the effect of income inequalities on tooth loss is attributable to differential exposure and susceptibility to heavy drinking in older Brazilian adults. METHODS: We conducted a secondary analysis using data from The Brazilian Longitudinal Study of Ageing (ELSI-Brazil 2015-2016), a nationally representative sample of community-dwelling people aged 50 years and over. Causal mediation analysis based on the counterfactual outcome framework decomposed the effect of income on tooth loss mediated by heavy drinking into four components (four-way decomposition): controlled direct effect (neither mediation nor interaction), reference interaction (interaction only), mediated interaction (both mediation and interaction) and pure indirect effect (mediation only). Proportions of effect attributable to each component were calculated to estimate the differential exposure (the sum of the third and fourth components) and differential susceptibility (the sum of the second and third components) to heavy drinking. RESULTS: The analytical sample comprised 8114 participants. After adjusting for covariates, 7.3% (95% CI: 3.8%; 10.9%) and -39.5% (95% CI: -75.8%; -3.3%) of the effects of income on tooth loss were attributable to differential exposure and susceptibility to heavy drinking, respectively, consistent with the alcohol harm paradox. When setting non-functional dentition as outcome, only the effect of differential susceptibility remained (-81.7% [95% CI: -128.2%; -35.2%]). CONCLUSION: Our findings suggest that individuals of low-income groups appear to be more susceptible to the effects of heavy drinking on tooth loss.

OBJECTIVE: This study examined the effect of retirement on self-rated oral health and dental services use. METHODS: Covering 31 countries, we used harmonized panel data from the English Longitudinal Study on Aging (ELSA), Health and Retirement Study (HRS), and the Survey of Health, Aging and Retirement in Europe (SHARE). Data comprised 485 085 observations from 112 240 individuals aged ≥50 years. Official and early retirement ages were leveraged as instruments in a fixed-effects instrumental variable approach. RESULTS: We found that retirement exhibited a negative effect on self-rated oral health (ß = -0.37; 95% confidence interval (CI) -0.44- -0.30) and a positive effect on the propensity to seek dental care (ß = 0.56; 95% CI 0.53-0.60). Male retirees showed a stronger decrease in self-rated oral health and increase in dental services use than female retirees. Participants who previously worked in a physically demanding job showed a stronger effect on self-rated oral health. Conversely, participants without a physically demanding job in the past exhibited a stronger retirement effect on dental service use. Compared with other health system clusters, retirement effects on dental services use were stronger in three health system clusters: Belgium, Denmark, Finland, France, Ireland, Luxembourg, The Netherlands, and Sweden; Israel; and the United States. CONCLUSIONS: Using a quasi-experimental design, we found that transition to retirement lowers self-rated oral health and increases the use of dental services. Retirement effects appeared heterogeneous across sexes, type of previous labor, and health systems.

OBJECTIVES: Periodontitis is a non-communicable disease (NCD) that may be linked to other NCDs through shared risk factors. Accordingly, we analyzed the relationship between periodontitis and behavioral and metabolic risks common to NCDs in Brazilian adults over three decades. METHODS: Indicators of periodontitis, behavioral risks (smoking, alcohol use, sugar-sweetened beverages (SSB), and physical activity), and metabolic risks (overweight/obesity, dyslipidemia, hyperglycemia, and hypertension) in Brazilian adults (25-49 y-old) between 1990 to 2019 were obtained from the Global Burden of Disease Study 2019. Data were adjusted for Gini index. Fixed-effects and Prais-Winsten regressions were performed (p < 0.05). RESULTS: The prevalence of periodontitis has increased among Brazilians since 2005. High-SSB diet, alcohol use, and metabolic risks increased between 1990-2019, whereas smoking decreased. In crude models, periodontitis prevalence increased with alcohol use (2545.1; 95%CI: 2307.9-2782.3), high-SSB diet (365.5; 95%CI: 322.5-408.4), low physical activity (1784.4; 95%CI: 763.7-2805.0), overweight/obesity (172.3; 95%CI: 156.3-188.4), dyslipidemia (734.5; 95%CI: 624.7-844.2), and hyperglycemia (1774.3; 95%CI: 1555.9-1992.7). After adjustment for the Gini index, periodontitis prevalence raised with a high-SBB diet (1416.0; 95%CI: 1120.2-1711.8), overweight/obesity (629.9; 95%CI: 573.1-686.8), dyslipidemia (2035.8; 95%CI: 1728.1-2343.5), and hyperglycemia (8918.1; 95%CI: 7979.8-9856.3). CONCLUSIONS: Periodontitis has increased in Brazil since 2005, despite the smoking reduction. Sugar-sweetened beverage was the behavioral risk that mostly accompanied the periodontal trend. CLINICAL RELEVANCE: Our results support upstream strategies targeting commercial, social, political, and structural determinants to tackle NCDs and reduce oral health inequities.

OBJECTIVES: This study aimed to identify studies exploring oral and systemic conditions using Singapore data. METHODS: Studies were searched using the databases PubMed, Embase and Web of Science, with no publication date or language restrictions. Studies analysing Singaporean data were included in this review. RESULTS: Six domains were identified: pregnancy and gingivitis; tooth eruption, dental caries and early-life factors; Crohn's disease and oral microbiome; diabetes and periodontal diseases; number of teeth, chewing ability and cognitive status; and oral health and pneumonia. Using data from Singapore, oral-systemic studies have prompted reflections on the aetiopathogenesis of oral disorders, such as common causes connecting oral and systemic chronic conditions. Moreover, it is speculated whether oral conditions could be used as a marker to predict future systemic diseases or whether early-life factors could affect the development of oral and systemic immune responses. CONCLUSIONS: While Singapore provides opportunities to explore challenges connected to healthy ageing, it also explores health development in many stages of life. Singapore has been prioritizing investigations on a healthier life, and new initiatives are paving the way for oral health research across the lifespan.
ABSTRACT
The World Health Organization member states proposed a comprehensive "Global Strategy on Oral Health," which includes achieving universal oral health coverage by 2030. Challenges and barriers, including persistent inequalities, will hamper the achievement of universal oral health coverage. In low- and middle-income countries, the oral health of a large proportion of the population has been neglected, increasing oral health inequalities. In high-income countries, some receive excessive dental treatment, whilst particularly those with higher needs receive too little dental care. Therefore, an analysis of individual countries' needs, encompassing the training of oral health professionals in a new philosophy of care and attention and the optimisation of the existing resources, is necessary. Distancing from a person-centred focus has prompted individual and societal issues, including under-/overdiagnosis and under-/overtreatment. The person-centred approach considers the perceptions, needs, preferences, and circumstances of individuals and populations. Patient-reported outcome measures, such as self-rated and -reported health, reflect an individual's overall perception of health and are designed to mediate human biology (ie, the disease) and psychology. The usage of patient-reported outcome measures in dentistry to place the individual at the centre of treatment is delayed compared to other areas. This paper discusses some challenges and potential solutions of patient-reported outcome measures in dentistry for achieving universal oral health coverage.

Increased dental overjet in adolescence is a clinically relevant outcome associated with the complexity and high cost of treatment, indicating the need for prevention strategies. We investigated the long-term impact of breastfeeding and pacifier use on increased overjet (IOVJ) in permanent dentition. A prospective cohort nested in a randomized controlled trial was conducted from birth to 12 years of age (n = 214). Breastfeeding and pacifier use were recorded monthly until 12 months. Overjet was assessed at age 12 years. We employed a causal mediation analysis using parametric regression models assuming no interaction between breastfeeding and pacifier usage. We found a total protective effect of breastfeeding on IOVJ (OR 0.49; 95% CI 0.28-0.96), where 63.1% were mediated by pacifier use (OR 0.61; 95% CI 0.44-0.87). Breastfeeding directly decreased the odds of IOVJ by 20%; however, the confidence interval included the null estimate (OR 0.81; 95% CI 0.41-1.60). In conclusion, breastfeeding protects by half of the IOVJ in adolescence through reducing pacifier use. Oral and general health professionals should collaborate to support WHO breastfeeding guidelines during individual patient counseling. Guidelines for practice, policy or public information require messages that include a common risk approach to oral and general health.

OBJECTIVES: Federated learning (FL) has gained popularity in clinical research in recent years to facilitate privacy-preserving collaboration. Structured data, one of the most prevalent forms of clinical data, has experienced significant growth in volume concurrently, notably with the widespread adoption of electronic health records in clinical practice. This review examines FL applications on structured medical data, identifies contemporary limitations, and discusses potential innovations. MATERIALS AND METHODS: We searched 5 databases, SCOPUS, MEDLINE, Web of Science, Embase, and CINAHL, to identify articles that applied FL to structured medical data and reported results following the PRISMA guidelines. Each selected publication was evaluated from 3 primary perspectives, including data quality, modeling strategies, and FL frameworks. RESULTS: Out of the 1193 papers screened, 34 met the inclusion criteria, with each article consisting of one or more studies that used FL to handle structured clinical/medical data. Of these, 24 utilized data acquired from electronic health records, with clinical predictions and association studies being the most common clinical research tasks that FL was applied to. Only one article exclusively explored the vertical FL setting, while the remaining 33 explored the horizontal FL setting, with only 14 discussing comparisons between single-site (local) and FL (global) analysis. CONCLUSIONS: The existing FL applications on structured medical data lack sufficient evaluations of clinically meaningful benefits, particularly when compared to single-site analyses. Therefore, it is crucial for future FL applications to prioritize clinical motivations and develop designs and methodologies that can effectively support and aid clinical practice and research.
