Abstract

Aim and background:Dental adhesives have three-step, two-step, and one-step bonding systems available. Multicomponent bonding systems are being replaced by user-friendly, simplified, consolidated adhesives. The aim of this research was to restore noncarious cervical lesions (NCCLs) and compare the in vivo therapeutic effectiveness of two self-etch adhesives to etch-and-rinse adhesives over 12 months. Materials and methods: A double-blind, randomized, parallel, longitudinal study with a total of 60 teeth with NCCLs was randomly allocated to three groups: group I—Adper single bond 2, (control) group II—Clearfil SE, group III—G-bond. The teeth were restored with nanocomposite. The restored teeth were scored using modified United States Public Health Service (USPHS) criteria regarding retention, marginal discoloration, marginal adaptation, sensitivity, surface texture, and color match, which were evaluated at three different time intervals, that is, at baseline, 6 months, and 1 year. The Kruskal–Wallis test was used for statistical analysis. Results: At baseline, all the restorations of all three groups scored α for all evaluated variables. At 6 months, restorations of both Clearfil SE and G-bond groups showed 100% retention rates, and at 1 year, the retention rates were 95 and 100%, respectively. Slight marginal discoloration and lower marginal adaptation occurred with both the self-etch adhesives; however, none of the results was statistically significant when compared to the control group. Conclusion: Self-etch adhesives showed good clinical performance in comparison to the etch-and-rinse system; however, a longer observation period is required to support the results of this investigation. Clinical significance: Self-etch adhesives showed comparable clinical efficacy to etch-and-rinse adhesives. They are a good alternative to traditional adhesives as they have limited steps and are less technique-sensitive.
