  ABSTRACT: Introduction: Root canal system obturation uses filling materials and sealers that should present, among other proprieties, a biocompatibility to the periradicular tissues. Objective: To compare, in vivo, bone tissue response to two types of biomaterials: Resilon points and gutta-percha points. Material and methods: For this purpose, 40 male albino Wistar rats were used for implantation of the biomaterial points in their previously perforated left tibia. Twenty rats received gutta-percha point implants and the other 20 rats received Resilon point implants. All animals had their right tibia partially perforated, as a control group. At the end of the 2nd, 4th, 8th and 16th week post-implantation, bone tissue samples were taken for analysis. Histological sections were stained by HE, photographed, and morphologically analyzed using TPS Dig 1.38 software. Tissue response was analyzed, taking into consideration the periosteum thickness variation in the formed bone callus area. Results: Data were statistically analyzed by ANOVA, followed by Tukey’s test (p < 0.05). There was no statistical difference between the materials tested, when the periosteum thickness was analyzed. Conclusion: Both Gutta-percha and Resilon points were biocompatible and well tolerated when implanted in bone tissue of rats.
