– To explore the association between incisal trauma and occlusal characteristics using oral examination and health interview data from the Third National Health and Nutrition Examination Survey 1988–1994 (NHANES III). Incisal trauma examinations were performed on 15 364 individuals 6–50 years of age using an ordinal scale developed by the National Institute of Dental and Craniofacial Research. Occlusal examinations were performed on 13 057 individuals 8–50 years of age. We fitted separate multivariate logistic regression models for maxillary and mandibular incisor trauma adjusting for socio‐demographic variables (age, gender, race‐ethnicity) and occlusal characteristics (overbite, overjet, open bite). 23.45% of all individuals evidenced trauma on at least one incisor, with trauma more than four times more prevalent on maxillary (22.59%) than on mandibular incisors (4.78%). Males (OR = 1.67) had greater odds of trauma than females; Whites (OR = 1.37) and non‐Hispanic Blacks (OR = 1.37) had greater odds of trauma than Mexican–Americans. The odds of trauma increased with age, peaked from age 21 to 30 (OR = 2.92), and declined. As overjet increased, so did the odds of trauma. Compared to individuals with ≤0‐mm overjet, odds of trauma increased from 1–3 mm (OR = 1.42) to 4–6 mm (OR = 2.42) to 7–8 mm (OR = 3.24) to >8 mm (OR = 12.47). Trauma to incisors is prevalent but mostly limited to enamel. Trauma to maxillary incisors is associated with overjet, gender, race‐ethnicity, and age, while trauma to mandibular incisors is associated with gender, age, and overbite.
