The purpose of this population-based epidemiologic study was to clarify the tempromandibular disorders prevalence, the maxillofacial trauma experience rate and the relation between maxillofacial trauma and tempromandibular disorders in 6-14 and 16 years old korean children who were selected through the stratified random sampling method, the results are as follows;
1. The prevalence of tempromandibular clicking sounds was 1.28% in elementary students, 11.05% in middle school students, 20.07% in high school students, with an overall 6.30%. The result of the statistical test showed that girls experienced more tempromandibular clicking sounds than boys(p (0.05).
2. The prevalence of tempromandibular pain was 0.51% in elementary students, 1.95% in middle school students, 7.04% in high school students, with an overall 20.07%.
3. The prevalence in mouth opening limitation. was_ 0.04% in elementary students, 1.36% in middle school students, 5.85% in high school students, with an overall 1.06%.
4. The percentage of treatment experience for the tempromandibular disorders was 0.00% in elementary students, 0.77% in middle school students, 2.12% in high school students, with an overall 0.46%.
5. The maxillofacial trauma experience rate was 5.45% in elementary students, 9.11% in middle school students, and 11.89% in high school students, with an overall 7.22%. Males experienced more maxillofacial trauma than females(p(0.01), and urban students experienced more than rural students(p (0.05).
6. The results of the relation between maxillofacial trauma and tempromandibular disorders showed there were statistically significant relationship between the tempromandibular experience and the clicking sound(odds ratio 1.86), and between the maxillofacial trauma and tempromandibular disorders(odds ratio 1.79).
