Familial Presentation of Ankyloglossia and Localized Periodontitis.

An association between ankyloglossia and periodontitis has not previously been reported. This case series describes three sisters who each had ankyloglossia and a molar/incisor pattern of localized periodontitis. The concurrent presentation of both conditions within the family suggests that further investigation of genetic factors that might concurrently affect the pathogenesis of both disorders may be warranted.
