Abstract

Patients receiving radiation therapy as source of treatment are commonly known to have restorations on their tooth composed of resin or non-resin restorative materials. Any interaction between ionising radiations and these restorative materials can have adverse effects which can be of clinical significance. Hence in this study we investigated the effects of ionising radiation on 3 restorative materials (Impress Direct, Glass Ionomer Gold Label Type 9 and Te- Econom Plus) by testing their microhardness property. All the 3 composite materials showed increased mean micro hardness values among the radiated groups and was found to be statistically significant (P<0.05). The results obtained indicated that restorative materials has undergone increased degree of polymerisation strengthening the bonds sustaining its stability. Hence the above effect will have no adverse effects on the human health, hence these materials are suitable for endodontic treatment among patients undergoing radiotherapy for head and neck cancer.
