Abstract
We experienced a case of Stevens-Johnson syndrom in a boy at the age of 8 years and 7 months. Our findings are as follows:
1. Dental anomalies such as white spots of the enamel, anomaly of the root formation and enamel hypoplasia were observed. As the time that the Patient was diagnosed as Stevens-Johnson syndrom corresponded with the time his crowns and root were stating to form, it was suggested that the occurence of the teeth disturbance was associated with Stevens-Johnson syndrom. A bald tongue was also observed and is considered to have been caused.
2. Mobility due to anomaly of the root formation (short roots) was observed in the maxillary bilateral incisors, mandibular bilateral incisors and mandibular right lateral incisors.
