Clinical performance of various bonding agents in noncarious cervical defects

Abstract

Aim: Four bonding agents and a composite restorative resin were evaluated in patients having noncarious cervical defects. Materials and Methods: This clinical trial was conducted in patients having at least 4 noncarious cervical defects in posterior teeth evaluating the clinical effectiveness in relation to retention, discoloration at margins, and postoperative sensitivity of 5 th , 6 th , 7 th , and 8 th generations of bonding agents over a period of baseline, 3, 6, 12, and 24 months. Statistical Analysis: Data were recorded and put into statistical analysis using Chi-square tests. Results: At 24 months, retention rate was found out to be 92.6% for the 7 th generation which was better than 5 th (66.7%) and 6 th (70.4%) generation whereas significant marginal discoloration was seen at 6 months follow-up in which 5 th generation showed maximum results. However, all the four generations have an equal score of postoperative sensitivity at all the time intervals. Conclusions: The 7 th generation adhesives performed better than other generations in terms of retention. Changes in marginal discoloration were detected at 6 months with maximum score in 5 th generation adhesives.
