[Study of ultrasonography applied to dental diagnosis. Examination of gingival morphology including epulis in relation to root surface].

Examination of gingival morphology was conducted using ultrasonic imaging equipment in a 57-year-old female with epulis. The ultrasonogram showed external gingival morphology including epulis and root surface caries which was difficult to detect because of masking by gingival enlargement. It appears that ultrasonograms are useful not only in examining gingival morphology but also in detecting changes in root surfaces hidden by the gingiva.
