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

Abstract

Several 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.
