Abstract

This study evaluated apical periodontal healing after root-end sealing using 4-META/MMA-TBB resin (SB), and root-end filling using reinforced zinc oxide eugenol cement (EBA) or mineral trioxide aggregate (MTA) when root canal infection persisted. Apical periodontitis was induced in mandibular premolars of beagles by contaminating the root canals with dental plaque. After 1 month, in the SB group, SB was applied to the resected surface following apicoectomy. In the EBA and MTA groups, a root-end cavity was prepared and filled with EBA or MTA. In the control group, the root-end was not filled. Fourteen weeks after surgery, histological and radiographic analyses in a beagle model were performed. The bone defect area in the SB, EBA and MTA groups was significantly smaller than that in the control group. The result indicated that root-end sealing using SB and root-end filling using EBA or MTA are significantly better than control.
