Effect of curing on clinical retention. A 7-year evaluation
Research output: Contribution to conference › Conference abstract for conference › Research › peer-review
Objective: To evaluate in a prospective evaluation the retention of Class V compomer and hybrid resin composite restorations placed with a 1-step self etch system and cured with continuous, soft-start and pulse-delay curing.
Methods: 139 Class V restorations were placed and cured at random in 60 subjects with a compomer (Dyract AP;68) or resin composite (Tetric Ceram:67) and cured for 40s with continuous, soft-start and pulse-delay modes. The restorations were evaluated with slightly modified USPHS criteria yearly during 7 years.
Results: Of 135 restorations evaluated at 7 years, 29 were lost, 17 compomer (25%) and 12 Tetric Ceram (18%). The cumulative loss rates for the compomer and resin composite restorations cured with the three curing modes were. continuous cure: 26.1%/18.2%, soft-start: 22.7%/19.0%, pulse delay: 26.1%/16.7%. No statistical difference were seen between the curing modes.
Conclusions: The clinical retention of Class V compomer and resin composite erosion/abrasion restorations was notinfluenced by the curing modes used.
