[The effect of composite filling materials on the diameter of the blood vessels of the dental pulp in rat teeth].
The authors tested the effect of some of the characteristic types of composite filling materials in a vital-microscope test. The results show that all the four tested filling materials (Biogloss, Evicrol, Isomolar, Isopast) significantly widened the pulpal arteriola; the Biogloss was ineffective for the diameter of the venula, but employing Evicrol, Isomolar and Isopast it was significantly increased. Between the tested materials compared to each difference was observed only during the development of their effect. The hyperaemia observed by us is important in case of short-time inspections as the indicator of acute reactions. Further test is required whether is there any connection between the tested hyperaemia and the toxic effect.
