Prevalence of narrow zone of attached gingiva and improper attachment of labial frena in youths.
An epidemiologic study comprising 1542 girls and boys aged 15--17 revealed that the occurrence of the narrowest attached gingiva zone (greater than 0, less than or equal to 1 mm) was more frequent in the mandible (23.0%) than in the maxilla (2.0%). At the same time, the first type of labial frena attachment (mucosal type) was observed most often, again dominating in the mandible (71.0%).
