RESUMEN
Objective To evaluate the effect of basic aloe mastic on the healing process after tooth extraction in rats. Methods The models of tooth extraction wound were established by extracting the left and right maxillary first molares in 60 Wistar rats,and randomly divided into two groups. Right sides of teeth extraction socket were used as experimental groups,experimental group 1 was filled with 30% aloe mastic ,experimental group 2 was filled with 50% aloe mastic. Left sides of teeth extraction socket were used as control group. The histological observation was performed after tooth extraction at 2,4,6,8,11,and 15 days. Results There was a significant difference of the wound areas between experimental groups and control group at early stage (15 d) after tooth extraction (P
