INTRODUCTION: Chewing betel nut (BN) is a well-established risk factor for several oral conditions, including periodontal diseases, but direct evidence linking BN chewing to pulpal and periapical (PA) pathology remains scarce. This study aimed to assess the association between BN chewing and apical periodontitis (AP).
MATERIALS AND METHODS: A cross-sectional observational study was conducted at two dental institutions in India from January 2021 to March 2023. A total of 222 participants were enrolled, comprising 113 habitual BN chewers (≥1 packet/day for ≥1 year) and 109 nonchewers with no history of tobacco use. Demographic, clinical, and radiographic data were collected through interviews, clinical, and radiographic examinations. Two calibrated endodontists evaluated radiographs to identify PA radiolucencies. Statistical analysis included chi-square tests, Mann-Whitney U tests, and Poisson log-linear regression models to assess the association between BN chewing and the number of AP lesions (α = 0.05).
RESULTS: BN chewers presented a higher number of AP lesions than nonchewers (p < 0.05). Poisson regression analysis showed that BN chewing was significantly associated with a higher number of AP lesions in both unadjusted (incidence rate ratio [IRR] = 1.504, p < 0.001) and fully adjusted models (IRR = 1.290, p = 0.034). Further analysis revealed a dose-dependent relationship, with each additional packet of BN chewed per day increasing the likelihood of AP lesions by ~11% and each additional year of BN use by around 3%-4%. No differences in the prevalence of carious lesions were observed between groups (p > 0.05).
CONCLUSION: BN chewing was independently associated with a higher prevalence of radiographic AP. Longer chewing duration was associated more strongly with PA lesion counts than chewing frequency. Given the cross-sectional design, these findings indicate association rather than causation, and longitudinal studies accounting for additional confounders are needed.
