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.
