12 MONTH CLINICAL EVALUATION OF DIFFERENT COMPOSITE RESINS USEDWITH A SELF-ETCH ADHESIVE SYSTEM IN THE RESTORATION OF NON-CARIOUS CERVICAL LESIONS

26196

Objective: The aim of this study was to evaluate the 12 month clinical performance of cervical restorations using nanohybrid and flowable composite resins. Material andMethod: 21 patients with at least 2 pairs of cervical lesions participated in this study.Atotal of 134 cervical lesions were restored, 67 with a nanohybrid composite resin (Grandio); 67 with a flowable composite resin (Grandio Flow), following the manufacturer s recommendation.Aone-step self-etch adhesive system (Futura Bond NR) was used as adhesive system for all groups.All restorations were placed by one dentist. No additional retention or bevel was performed. The restorations were clinically evaluated by two examiners at baseline, 6 and 12 month using modified USPHS criteria. The survival rates of restorations were calculated by the Kaplan-Meier and Log rank test. The comparison of two types of resin composites for each modified USPHS criteria was performed with the Pearson Chi Square test. Results: All patients attended the 12-month recall and all restorations were evaluated. At 6 month, the retention rate for nanohybrid composite resin, Grandio was 66 % and 58.2 % was for flowable composite resin, Grandio Flow. The retention rates at 12 month were 61.1 % for Grandio and 57 % for Grandio Flow. There were no statistically significant differences in retention rates among the adhesive systems after 6 or 12 months (p 0.05). No secondary caries, marginal discoloration or marginal adaptation was detected in association with any restorations and no postoperative sensitivity was observed. Conclusion: No difference was observed between the clinical performance of nanohybrid and flowable composite resins used in the restoration of servical lesions (p 0.05).
