CLEANING EFFECT OF TOOTHBRUSHING WITH 3 DIFFERENT TOOTHPASTES AND WATER

The cleaning effect of three different toothpastes and water was studi ed in vivo using a laser reflexion technique. Ten healthy persons form ed the test group. Light reflexion measurements on the upper front tee th were performed before and after the removal of a 72-hour plaque-pel licle. The results suggest that the toothpaste containing sodium bicar bonate as abrasive was less effective than a toothpaste containing alu minium silicate, calcium carbonate and dicalcium-phosphate dihydrate o r silicon dioxide and dicalcium phosphate dihydrate. The abrasivity of the toothpastes was compared in vitro. The in vitro results correspon d quite well to the in vivo findings.
