Abstract

Objective: The purpose of this study was to assess the sealing ability of three different temporary restorative materials on endodontic access cavities as compared to radiated and nonirradiated teeth. Materials and Methods: All teeth were randomly divided into two main groups according to the presence or absence of the radiotherapy. The specimens in these groups were then divided into three subgroups of 12 teeth each, and into two control groups of eight teeth each as negative and positive control groups. In radiotherapy groups, radiotherapy (1.8 Gy) was applied daily over 35 days resulting in a total application of 63 Gy. Standardized occlusal endodontic access cavities were prepared in all groups. A cotton pellet was placed on the pulp chamber. The access cavities were restored with three temporary filling materials; first fill, Cavit-G and Cavisol. The specimens were immersed in 2% methylene blue solution and centrifuged at 3000 rpm for 5 min. Results: Although there was no statistical difference among the three materials for the groups in which radiotherapy was not applied (P > 0.05), it was found that the sealing abilities of Cavit-G and Cavisol were not affected by radiotherapy (P > 0.05). However, the leakage values of the light-cured polymerized temporary filling material, first fill, were increased when radiotherapy was performed (P < 0.05). Conclusion: The radiotherapy application reduces the sealing ability of the light-cured temporary filling material, first fill.
