Abstract 

Objectives

This randomized controlled clinical trial evaluated the 2-year clinical performance of S3 Bond (S3) and G-Bond (GB) in 108 non-carious cervical lesions.

Methods

Twenty-three patients, 12 male and 11 female (mean age: 61.8 years, range: 30–79 years) regularly visiting the Nagasaki University Hospital of Medicine and Dentistry, participated in the study. Each patient received both materials randomly. All restorations (53 restorations for S3 and 55 restorations for GB) were placed by one dentist. The restorations were blindly evaluated by two examiners at baseline, 6 months, 1 and 2 years using modified USPHS criteria. The data were statistically analyzed using the Cochran Q test and Fisher's exact test.

Results

One restoration of each material was lost during 2 years. The only minor clinical problem was the integrity of the enamel margin. Slight marginal staining occurred adjacent to 11 restorations of both S3 and GB. There was no significant difference in the clinical performance between S3 and GB for each variable.

Conclusions

Under the protocol used in this study, S3 and GB have demonstrated an acceptable clinical performance up to 2 years.
