Post-treatment periodontal status of labially erupted maxillary canines

This study evaluates the level of the gingival margin of labially erupted maxillary canines after orthodontic treatment in a sample of 47 individuals with a mean age of 14.2 years. Gingival recession was found in 33% of the canines with a high labial eruption pattern, and in 11% of those with a moderate labial eruption. A highly significant correlation was found between the clinical crown height and the original degree of high labial eruption. The evidence of this study supports the case for implementation of interceptive orthodontic treatment in order to prevent high labial eruption of maxillary canines.
