This study was performed to use 12 teeth from 11 patients that were indicated to treat with metal crown restration. Each tooth was temporarily set 2 different shaped metal crowns for 4 weeks, one of these was made with under-contoured proximal surface and the other had over-contoured proximal surface. One week after temporarily setting the crown, the plaque accumulated on the crown was stained with disclosing solution and photographed with standerdized method. After this procedure, plaque on the proximal surface was removed with interdental cleaning devices, and the remained plaque stained and photographed with the same manner. The accumulation of plaque and the removal effect of plaque by interdental brush or dental floss were studied quantitatively at 1 week intervals on the color photograph. The following results were obtained: 1) The accumulation of plaque on the both shaped crowns could not be found significant differences. 2) It was shown that cleaning effect of dental floss was more effective on the distal surface than the mesial surface. 3) Using 3 strokes of both interdental cleaning devices, 90% of plaque was removed. 4) Plaque accumulated on the crown margins of under-contoured restration was more removed with interdental brush than with dental floss.
