Clinical investigation of G-Bond resin-based adhesive to non-carious cervical lesions over five years Academic Article uri icon

abstract

  • BACKGROUND: The aim of this study was to evaluate the clinical performance of G-Bond all-in-one adhesive with Gradia Direct resin composite placed in non-carious cervical lesions (NCCLs) over a five-year period. METHODS: Forty-seven restorations were placed in NCCLs in 10 subjects (age 45-75 years) after written informed consent was obtained. Institutional ethical approval for the trial was obtained before recruitment. Restorations were placed according to the manufacturer's instructions and using 50% phosphoric acid to etch uncut enamel margins. Patients were recalled annually for five years and restorations reviewed for presence and marginal staining. Photographic records were obtained prior to restoration, immediately after placement and at each recall. RESULTS: At five years, 6 of the original 10 subjects were available for recall, meaning 27 restoration sites could be evaluated. All restorations remained intact apart for one partial failure at four years. This resulted in a cumulative retention rate of 97.5% of restorations at five years. Marginal staining occurred around seven restorations during the study. Staining tended to be isolated to a few patients. CONCLUSIONS: It was concluded that G-Bond with Gradia Direct resin composite showed excellent results over the five years of the study. This material combination seems very suitable for the restoration of NCCLs.
