Abstract

Background: Dental complications is the common problem faced all over the world. Subjects with poor oral hygiene and patients undergoing radiotherapy for oral cancers are developing signs of decalcification of enamel, lesions and Caries. Hence a well-designed treatment is essential to protect the teeth among the patient population. Objective: To determine the annealing effect of radiated tooth by testing maximum micro hardness of the teeth before and after 30 days of radiation. Methodology: In our study, we collected 30 intact caries free human molar teeth and were sectioned mesio-distally. The sectioned teeth were divided into 3 groups as control, ACP CCP Coated teeth and ACP CCPF coated teeth. All the samples were maintained in artificial saliva before and after radiation to sustain oral environment. Samples were subjected to Radiation dosage of 70Gy and the microhardness profile was assessed before, after and after 30 days of radiation treatment. The results obtained were statistically analysed by performing bonferroni adjustment for pairwise comparisons and one way ANOVA for multiple comparison test at P
