Resumo: Objective: This study tested rat connective tissue response to RealSeal, RealSeal primer or AH Plus after 7, 15, 30, 60 and 90 days of implantation. Material and methods: Thirty Wistar rats had subcutaneous sockets created on their back and received four implants each of polyethylene tubes containing one of the materials tested according to the groups: AH (AH Plus Sealer); RS (RealSeal Sealer); RP (RealSeal Primer); CG (control group – empty tube). After histological processing, sections were analyzed to identify the presence of neutrophils, lymphocytes and plasma cells, eosinophils, macrophages and giant cells, as well as fibrous capsule and abscesses, by an examiner using ligth microscope. Kruskal-Wallis and multiple comparisons test were used for statistical analysis. Significance level was set at 5%.Results: Lymphoplasmacytic infiltrate scores significantly higher than of the control group were observed at 14 and 60 days in AH group, and at 90 days in RS group (p<0.05). There were no differences in terms of presence of macrophages, giant cells, eosinophils, neutrophils and fibrosis. AH Plus group scored higher for abcesses at seven days than any other period (p=0.031)RP group scored higher for lymphoplasmacytic infiltrate at 14 days than at 90 days. Conclusion:The main contribution of this study was to demonstrate that issues involved with tissue tolerance of a Resilon-containing sealer, RealSeal Sealer, cannot be attributed to its primer content.
