Clinical Performance of Aesthetic Restorative Materials in Class-V Restorations

Objectives: The purpose of this study was to evaluate the clinical performance of a resin modified glass ionomer, two polyacid modified resin composites and a resin composite in Class-V restorations over a 2-year period. Methods: One hundered and thirty restorations with four restorative materials ; 24 with Vitremer (3M Dental Products), 38 with F2000 Compomer (3M Dental Products), 46 with Dyract AP (Dentsply/Detrey), 22 Valux Plus (3M Dental Products) were performed to noncaries cervical lesions of 30 patients. Over a 2-year period, two independent, calibrated examiners recorded the clinical effectiveness using the modified USPHS Criteria. Results: Retention rates were 100% for Vitremer, 67% for F2000 Compomer, 68% for Dyract AP and 70% for Valux Plus. The retention rate of Vitremer was significantly higher than the others (p<0.05). However, the most favourable performance was observed for Valux Plus at marginal adaptation, surface roughness, marginal discoloration, anatomic form and colour match criteria (p<0.05). Polyacid modified resin composites (F2000 Compomer and Dyract AP) had neither aesthetic properties like that of resin composite (Valux Plus), nor retention rate as much as that of resin modified glass ionomer (Vitremer). No secondary caries were detected around any restoration. Conclusion: Resin modified glass ionomer, polyacid modified resin composites and resin composite had divergent clinical performances in Class-V restorations.
