Gingival contour was changed in ten Macaca fuscatus either by use of an overcontoured class V inlay set on the facial surface of teeth or by removal of the tooth structure on the surface of teeth. The changes thus induced in the gingival tissue were observed clinically and histopathologically for 12 weeks. Effects of difference in gingival contour of the facial surface of teeth were examined on the basis of the observation data. The results were as follows : 1. In the non-plaque control side, gingival inflammation and plaque formation increased clinically with time in overcontour, normalcontour, and undercontour. 2. In the non-plaque control side, gingival inflammation and plaque formation increased slightly greater clinically in overcontour than in normalcontour. Little difference however was observed histopathologically. 3. In the non-plaque control side, little difference was observed clinically and histopathologically between normalcontour and undercontour. 4. Gingival inflammation in overcontour, normalcontour, and undercontour in the non-plaque control side increased clinically and histopathologically as compared with the plaque control side and the brushing side. 5. In the plaque control side and the brushing side, no increase with time in gingival inflammation and plaque formation was observed clinically in overcontour, normalcontour, and undercontour. 6. In the plaque control side and the brushing side, little difference was observed clinically among overcontour, normalcontour, and undercontour. 7. Between the plaque control side and the brushing side, little difference was observed clinically and histopathologically in overcontour, normalcontour, and undercontour.
