【 摘 要 】

OBJECTIVE: This study aimed to evaluate oral and maxillofacial trauma caused by falls during epileptic seizures. METHOD: A prospective case-control study was carried out among patients recruited from both the Epileptic Outpatient Clinic and the Emergency Room of Hospital de Base during 2006. The study group was composed of patients with epilepsy that had been diagnosed by a specialist. Oral and maxillofacial trauma was diagnosed using a questionnaire together with physical and radiographic examinations. A control group was formed from non-epileptic relatives or neighbors of the patients. The two groups were compared with regard to the number and type of oral and maxillofacial trauma events suffered. Odds ratios with a 95% confidence interval, dependency analysis and the Pearson c² test were used for statistical analysis, and the significance level was set at p≤0.05. RESULTS: A total of 159 patients with epilepsy (91 males; 57.3%) and 68 control individuals (28 males; 41.1%) were enrolled in the study. The frequencies of oromaxillary trauma in the study and control groups were 23.9% and 4.4%, respectively. Generalized tonic-clonic, generalized and non-classified seizures were strongly associated with trauma. The commonest lesions were fractures of dental tooth crowns (32.9%), followed by tooth avulsion (7.6%), tooth luxation (5%) and fracturing of prostheses in edentulous patients (3.8%). CONCLUSION: This work shows that injuries to the face and teeth are statistically more common in patients with epilepsy than in the general population, and that individuals who suffer seizures without aura are the most affected.
