Özet:

 Objective: Radiation-induced oral mucositis is a major problem associated with radiotherapy. This study aimed to investigatetheeffectiveness of polyether silicone-based PE and polyvinyl siloxane PVS impression materials in protecting adjacent tissuesfrom radiation scattered from dental materials. Materials and Methods: Amalgam, zirconium, and titanium dental material specimens were covered with 5 mm PE and PVSinthestudy group. The dental materials were placed in a linear accelerator device at a distance of 100 cm from the radiation sourceandcoincided with a field size of 15x15 mm. Samples placed perpendicular to the central beam were irradiated with 6 MV photonsat a fractional daily therapeutic radiation dose of 2 Gy. Thermoluminescent dosimeters TLD-100 placed 90 degrees lateral tothespecimens were used to record the scattered dose data. In the control group, uncovered dental materials were irradiated, andscattered doses were measured by TLD. The TLD data of the study and control groups were compared by independent t-test toanalyze the shielding effect of PE and PVS. In addition, the photon stopper properties of PE and PVS were compared. The photoninteraction parameters and effective atomic numbers of dental materials were calculated. Results: It was calculated that the PE and PVS significantly prevent the dose enhancement caused by dental materials p0.05. There was no difference between impression materials in the photon-stopping properties p0.05. Conclusion: PE and PVS can be used as scatter dose shields for the 2 Gy daily fractional dose. This study demonstratestheradiation-shielding properties of PE for the first time.
