OBJECTIVE: To analyze the prognosis of uncomplicated crown fractures and the related factors.
METHODS: Clinical data of uncomplicated crown fractures treated in Department of Pediatric Dentistry, Peking University School of Stomatology from 2000 to 2006 were collected, and the follow-up period was not shorter than six months. The following information was recorded, including patients' age and gender, type of injury, with or without luxation injury, location of injured tooth, stage of root development, time elapsed between the injury and the first dental care, emergency treatment or not, pulp healing. Logistic regression was used for statistical analysis.
RESULTS: The study comprised of 307 patients with 415 uncomplicated crown-fracture teeth. The frequency of pulp necrosis was significantly higher in crown-fracture teeth with luxation injuries (34.0%) than in crown-fracture teeth without luxation injuries (22.7%) (P < 0.05). Age of patients and type of injury were significantly related to pulp prognosis in crown-fracture teeth without luxation injuries. While stage of root development and type of injury were significantly related to pulp prognosis in crown-fracture teeth with luxation injuries.
CONCLUSION: Luxation injuries was significantly related to the prognosis of uncomplicated crown-fracture teeth.
