Prevalence and risk factors of erosive tooth wear among young adults in the Singapore military.

OBJECTIVES: Erosive tooth wear (ETW) is defined as the irreversible chemo-mechanical loss of dental hard tissues without plaque or bacteria and has been a growing phenomenon in the general population worldwide. The aim of this study was to determine the prevalence of ETW and the associated risk factors among young military personnel in Singapore. MATERIALS AND METHODS: This cross-sectional study consisted of a questionnaire and clinical examination of military personnel between 18 and 25 years. The questionnaire collected information on demographics, medical and dental history, lifestyle and dietary habits. Tooth wear was clinically evaluated using the Basic Erosive Wear Examination (BEWE) index. The participants were profiled into four risk categories (none, low, moderate, severe) based on the sum score. Multivariable logistic regression analysis was performed to determine the risk factors associated with the presence of ETW. RESULTS: Out of 1296 participants evaluated, 21.8% of them had ETW. The anterior sextants were more affected by erosion than posterior sextants for both arches. The risk factors significantly associated with ETW were GERD (OR = 2.83, p = 0.041), presence of self-reported TMD symptoms (OR = 2.51, p < 0.001), acidic food (OR = 2.03, p < 0.001) and drinks (OR = 3.07, p < 0.001), high caries risk (OR = 4.59, p < 0.001) and toothbrush stiffness (OR = 4.67, p < 0.001). CONCLUSION: ETW is prevalent among the young military population, with over half of the population at a risk of ETW. Gastric reflux disease, TMD, acidic diet, dental caries susceptibility and the use of stiff toothbrushes were identified as significant risk factors. CLINICAL RELEVANCE: A large proportion of young military personnel exhibited mild to moderate risk of ETW. Dental professionals can identify risk-susceptible individuals at a young age and educated them with preventive measures and dietary interventions to prevent the progression of the condition.

Interim therapeutic restoration approach versus treatment under general anaesthesia approach.

BACKGROUND: Although dental treatment under general anaesthesia (GA) remains the long-established approach for treating anxious children, treatment under GA presents with increased risks, costs and parental acceptability issues. Interim therapeutic restoration (ITR) has been proposed as an alternative approach. AIM: To compare the incidence and types of failures between children managed with the ITR approach and those managed under GA within 12 months of treatment completion. DESIGN: A retrospective cohort study of children who received dental treatment utilizing the ITR approach was compared to children treated under GA. Age, gender and dental disease matching was done. Statistical analyses were carried out with Independent t-test and chi-square analyses. RESULTS: A total of 132 children (GA = 66, ITR = 66) were included, and the groups did not differ in terms of initial age, sex, dmft and initial behaviour score. ITR group had a significantly higher rate (P < 0.001; 95% CI: [0.21 to 0.97]) of restorative failure and visits required when compared to the GA group. There were no difference for incidence of pain (P = 0.55; 95% CI: [-0.074 to 0.10]) and behaviour scores (P = 0.46) between the two groups at the 12-month visit. CONCLUSIONS: ITR approach may be a viable alternative to the GA approach when treating paediatric dental patients.

Accuracy of Dental Symptom Checker Web Application in the Singapore Military Population.

PURPOSE: Symptom checkers (SCs) are virtual health aids to assist laypersons in self-assessing dental complaints. This study aimed to investigate the triage performance, clinical efficacy, and user-perceived utility of a prototype dental SC, Toothbuddy, in assessing unscheduled dental complaints in Singapore. METHODS: A pilot trial was conducted amongst all unscheduled dental attendees to military dental facilities in Singapore from January to May 2023. The accuracy of Toothbuddy to tele-triage dental conditions into 3 categories-routine, urgent, and emergency-was determined. Based on the patient-reported symptoms input, clinical recommendations were provided to users for each category. Thereafter, all dental attendees were clinically assessed to determine the definitive category. Finally, a user questionnaire assessed the application's functionality and utility and the user's satisfaction. Sensitivity and specificity analyses were performed. RESULTS: During the study, 588 patients with unscheduled dental visits presented. Of these cases, 275 (46.8%) were evaluated to be routine dental conditions for which treatment could be delayed or self-managed, 243 (41.3%) required urgent dental care, and 60 (10.2%) required emergency dental intervention. The accuracy of Toothbuddy in identifying the correct category was 79.6% (468/588). Sensitivity and specificity in categorising routine vs non-routine conditions were 94.5% (95% confidence interval, 92.0%-97.1%) and 74.0% (95% confidence interval, 68.8%-79.2%), respectively. The app was generally well received and rated highly. CONCLUSIONS: Preliminary data suggest that Toothbuddy can perform accurate dental self-assessment for a suitable range of common dental concerns and this is a promising platform for virtual advice on spontaneous dental issues. Furthermore, dental facilities are typically not sized to handle the large volumes of unplanned dental visits that may occur in the military population. SC apps to self-manage or delay treatment without adversely affecting disease prognosis may preserve the limited bandwidth of dental facilities in providing acute care and managing true dental emergencies expediently.
