Short summary
Higher BMI and waist circumference are significantly associated with increased tooth wear severity (BEWE scores ≥ 14) in Pakistani adults, though overall oral health quality of life (OHRQoL) did not significantly differ across wear categories.

Key points
- Higher BMI and waist circumference are significantly associated with increased tooth wear severity in Pakistani adults (p < 0.001).
- 22.3% and 28.8% of participants in increased and higher-risk BMI categories, respectively, had BEWE scores ≥ 14.
- Overall Oral Health-Related Quality of Life (OHRQoL) did not significantly differ across tooth wear categories (p = 0.956).
- Participants in higher tooth wear risk groups showed significantly greater impairment in taste perception (p < 0.05).

Abstract
This study evaluated the association between tooth-wear risk and obesity-related measures, and explored its impact on the Oral-Health-Related Quality of Life (OHRQoL) among Pakistani adults. This single-centred cross-sectional study examined tooth wear using the Basic Erosive Wear Examination (BEWE) in 406 participants visiting the dental clinics of a tertiary care hospital, aged 18–65 years. The Oral Health Impact Profile-14 (OHIP-14) questionnaire, available in English and a validated Urdu translation, was completed. Age, sex, weight, height, Body-Mass Index (BMI), and waist circumference (WC) were recorded. Data were analysed using. SPSS version 23.0. Higher BMI and WC were significantly associated with increased tooth wear severity ( p < 0.001). Thirty-five (22.3%) and 44 (28.8%) participants in the increased and higher-high risk BMI categories, respectively, had BEWE scores ≥ 14. Fifty-seven (32.8%) males and 19 (17.3%) females in the excessive risk group for WC had BEWE scores ≥ 14. Multinomial logistic regression showed that increasing BMI and WC were significantly associated with higher odds of being in the medium- and high-risk tooth wear groups. A slight increasing trend in OHIP-14 scores was observed with increasing wear severity, differences across risk groups were not statistically significant ( p = 0.956). However, specific functional impacts were observed; participants in higher tooth wear risk groups and those reporting frequent GERD symptoms showed significantly greater impairment in taste perception ( p < 0.05). Higher BMI and waist circumference were associated with higher BEWE tooth-wear categories among Pakistani adults. BMI and waist circumference represent general and central adiposity, respectively. However, the cross-sectional design precludes conclusions regarding causality or tooth-wear progression. Overall OHRQoL did not differ significantly across tooth-wear categories, although an exploratory association with worsening taste perception was observed.
