Abstract
OBJECTIVE: The clinical suitability of low-shrinkage resin composites for class V cavities has not been investigated in vivo. The purpose of this double-blind randomized clinical trial was to compare the clinical performances of low-shrinkage resin composite Filtek silorane and nanoceramic resin composite Ceram X mono in non-carious cervical lesions (NCCLs) over 36 months. MATERIALS AND METHODS: Two calibrated operators restored 144 NCCLs in 24 patients by using Filtek silorane with silorane system adhesive (FS/SSA) and Ceram X mono with Clearfil SE (CXM/CSE) or XP bond (CXM/XPB). Then, two blinded, calibrated evaluators assessed the restorations at the baseline and 6, 12, 24, and 36 months thereafter by using the modified US Public Health Service criteria. Data were analyzed with the Freidman and Wilcoxon signed-rank tests at a significance level of 5 % (P < 0.05). RESULTS: No restoration was associated with postoperative sensitivity or secondary caries. Further, no group showed significant changes until 12 months. The retention rates of the FS/SSA (97.5 %), CXM/CSE (97.5 %), and CXM/XPB (92.31 %) restorations did not differ significantly (P > 0.05). Six (4 CXM/XPB, 1 FS/SSA, and 1 CXM/CSE) of the 121 restorations evaluated at 36 months were completely lost. However, no significant intergroup differences were observed in the other evaluation criteria. CONCLUSION: The 3-year clinical performances of the restorative materials in NCCLs were not significantly different. CLINICAL RELEVANCE: Filtek silorane is suitable for restoring NCCLs.
