One Year Clinical Evaluation of Class V composite Restoration Using Tow different Placement Techniques

Abstract

AbstructSeveral techniques are proposed for the restoration of Class V cavities but there is no agreement in the literature as to which technique is more effective. The aim of this study was to compare a one-year clinical performance of class V composites using different placement technique.Thirty-eight class V cavity preparations in identical patients were prepared. One complete unit of composite and three increments of composite were used for restoration of class V preparations. The clinical criteria consisted of post-operative sensitivity, marginal discoloration, recurrent caries and marginal adaptation that were evaluated after one year.The t-test and Chi-square Pearson were used for analysis of data (P≤0.05). There was no significant difference between the two techniques regarding post-operative sensitivity and marginal adaptation. Marginal discoloration using three increments was significantly less than that of one complete unit.There was no significant difference in post-operative sensitivity between the two techniques. Marginal discoloration using 3 increments was significantly less than that of one unit. No significant failure was observed when using any of the techniques.
