clinical Evaluation of Self-etch Adhesives in Class V Carious Lesions

Objectives: The purpose of this randomized, controlled clinical study was to evaluate the 24-month clinical performance of four self-etch adhesive systems in combination with a nano-composite for the restoration of Class V carious lesions. Methods: Thirty-three patients with at least 2 equivalent carious cervical lesions were enrolled in the study. One hundred and twenty lesions were restored with a nano-composite (Grandio SO, Voco, Germany) (n=30/per adhesive system) according to the manufacturer's instructions by one operator. The tested adhesives were; Futurabond DC (Voco), Clearfil SE Bond (Kuraray, Japan), Adper Easy One SE adhesive (3M-Espe); G-Bond (GC- Europe). Two other independent examiners clinically evaluated the restorations for retention, color match, marginal adaptation, anatomic form, marginal discoloration, recurrent caries, post-operative sensitivity and surface texture at baseline, one year and two-years according to the modified USPHS criteria. Statistical analysis was completed using the Pearson Chi-square and Fisher's Exact Test (p<0.05). Results: Twenty-nine patients were available for recall after 2 years and 112 restorations were evaluated (recall rate of 93 %). All tested adhesives showed Alpha rating for anatomic form, recurrent caries, surface texture and post-operative sensitivity after two years. Two restorations of Adper Easy One SE and one restoration of G-Bond were lost after two years. There was no statistically significant difference between the tested adhesives after two years (p > 0.05):Conclusions: Considering all the clinical evaluation criteria, all tested adhesive systems performance was found to be acceptable for the restoration of Class V carious cervical lesions over a period of 24-months.
