Clinical evaluation of SonicFill restorations in Class II cavities up to 2 years
Objectives: This clinical study evaluated the clinical performance of a bulkfill resin composite in Class II cavities up to 2 years.
Methods: Methods: Between March-2013 and January-2014, a total of 52 patients (15 male, 37 female, mean age: 27.2±11 years old), received 111 direct Class II restorations in premolars and molars by two operators and were followed up until April 2015. After conditioning the tooth with one-step etch-and-dry adhesive system with selective etching technique, restorations were made using a bulk fill nano-hybrid resin composite (SonicFill, Kerr/Sybron) according to the manufacturer`s instructions. Two independent calibrated operators evaluated the restorations 1 week after placement (baseline), at 6 months and thereafter annually up to 2 years using USPHS criteria for anatomic form, marginal adaptation, color match, surface roughness, marginal discoloration, secondary caries, post-operative sensitivity and gingival health. The changes in the USPHS parameters were analyzed using McNemar test (alpha= 0.05) and Kaplan-Meier.
Results: Mean observation period was 17 months. No secondary caries were observed until the final recall. One restoration received endodontic treatment after 2 months following the restorative procedure and accepted as failure. The overall success rate was 99.1% at final recall (Kaplan-Meier). Color match deteriorated from Score 0 to Score 1 (good color match) in 8 restorations from baseline to 6 months and final recall (p=0.008). Six restorations showed marginal staining and received Score 1 (slight staining, can be polished away) at final recall (p=0.031).
Conclusions: Bulkfill resin composite (SonicFill) showed acceptable clinical performance up to 2 years of service but colour match to tooth started showing deterioration already within the first 6 months.
