This study was carried out to know the plaque accumulation relative to the contour of artificial crowns. A total of 32 molar teeth from 17 patients being set artificial crown on one side of a jaw and the teeth of opposite side having no treatment were selected. The surface of the teeth and artificial crowns were polished. Then the patients were indicated not to use the tooth cleaning devices for 48 hours and the accumulation of plaque was measured. The length from gingival margin to the most convex point of the natural teeth and artificial crowns were measured facially and lingually. The following results were obtained: 1) On the artificial crown, plaque was less accumulated. 2) It was seemed that the accumulation of plaque was observed more on the overcontoured crown than undercontoured crown.
