Tooth wear and obesity: investigating the impact of BMI

Tooth wear and obesity: investigating the impact of BMI, waist circumference, and oral health-related quality of life. Download PDF 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. 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.
