Abstract

AIM: The aim of the present study was to assess the association of sex, age, group of teeth, and type of accident (exposure) with dental fractures (outcome: enamel-dentine fracture without [EDF] or with pulp exposure [EDPF] and root fracture RF]).

METHODS: In total, 1046 patients were selected. Logistic binary regression was used.

RESULTS: The findings showed that EDF has less change of affecting individuals ≤9 years of age than ≥40 years of age (odds ratio [OR]: 0.58, 95% confidence interval [CI]: 0.35-0.95). Violence (OR: 3.07, 95% CI: 1.77-5.31), traffic accidents (OR: 1.50, 95% CI: 1.05-2.13), and sporting accidents (OR: 1.70, 95% CI: 1.19-2.44)] were associated with EDF. Regarding EDPF, the mandibular lateral incisors had a 10 times higher chance of being injured than canines and posterior teeth (OR: 10.43, 95% CI: 1.74-62.4). Those aged ≤9 years (OR: 0.21, 95% CI: 0.07-0.58) and 10-19 years (OR: 0.38, 95% CI: 0.17-0.88) had a significantly lower chance of being affected by RF.

CONCLUSION: EDF and RF are associated with individuals ≥40 years of age; violence and traffic and sporting accidents are also associated with EDF, and mandibular incisors have a greater chance of being affected by EDPF.
