Clinical evaluation of adhesive restorations with and without Proanthocyanidins in Non Carious Cervical Lesions– 1 Year Follow up

Introduction & Objective: The deterioration of the hybrid layer in an adhesive restoration takes place over time resulting in the failure of restoration. The objective of this study was to compare the clinical efficacy of dentin adhesive applied over proanthocyanidin(PA) treated dentin for composite restorations in Non Carious Cervical Lesions (NCCLs) using the modified US public health service (USPHS) criteria. Materials and Method: Seventy NCCLs in selected subjects were assigned to two groups. In experimental group, the PA solution was applied during the bonding procedure and restored with nanofilled composite. The second group served as a control, where resin restoration was placed without modifying the dentin. Two examiners recorded clinical performance after 1week, 6 months and 12 months using modified USPHS criteria. Observation was recorded and statistical analysis was done. Results: PA group showed better result for various clinical criteria in comparison to the control group at 6 months and 12 months but there was no statistical significance. When evaluated within the group at different time interval the control group showed statistically significant difference for the retention (p=0.009) and marginal adaptation (p= 0.002). There was a loss of retention at 6 months and no further loss at the end of one year. Interpretation and Conclusion: PA conditioning during the adhesive procedure for composite restoration in NCCLs did not improve the various clinical parameter in comparison to control group when evaluated for a period of 1year.
