ABSTRACT: Aim: To evaluate invitro the effect of post obturation materials on reinforcement of peri-cervical dentin (PCD) Materials and Method : Sixty extracted, maxillary premolar teeth were selected.After preparation of standardized access, crowns were resected so that a final dimension of 4 mm from one mm below highest point of proximal cervical line was achieved. Then, the enamel was carefully removed.After obturation with gutta percha and AH plus sealer, post obturation protocol was followed: Group 1: Obturation + nRMGIC, Group 2: Obturation + silorane composite , Group 3: obturation + temporary cement and Group 4: No obturation + temporary cement.The specimens were tested for fracture resistace in universal testing machine.Data was analysed with student ‘t’ test and one way ANOVA. Results: Samples restored with nRMGIC and silorane composite presented with higher mean fracture resistance values of 941.20 & 929.17 N respectively when compared to obturated samples with tempoarary (490.50 N) followed by unbturated samples with temporary(396.11N) Conclusion: nRMGIC and silorane composite significantly reinforce PCD.Obturation also plays an important role in reinforcement of PCD.
