Effect of two types of composite resin on oral bacterial plaque. "In vitro qualitative and quantitative study".
160 specimens of composite (80 chemical and 80 light cured) were prepared in teflon mold 4 mm x 2.5 mm in dimension. Plaque samples were collected using absorbent paper points from 20 normal persons and 20 persons with cervical carious teeth. The samples were inoculated in TSB containing both types of composites. Duplicate cultures were done for aerobic and anaerobic incubations at 37 degrees C. There was no effect of both types of composite on the quality of the isolated organisms from normal group or patient group. Chemical and light cured composite increased significantly the count of aerobic bacterial plaque from normal group. While they decreased the count of aerobic bacterial plaque from patient group and also the anaerobic bacterial plaque from both normal and patient group.
