Abstract

Introduction: Ceramic inserts are claimed to reduce polymerization shrinkage and MICROLEAKAGE in posterior tooth-colored restorations. The purpose of this study was to evaluate the gingival MICROLEAKAGE in tooth colored restorations with ceramic-inserts (Cerana) in primary pulpotomized molar teeth.Materials & Methods: In this experimental in vitro study forty extracted human primary second molars were prepared with standardized MOD cavities so that the gingival margin was located on the dentin in mesial box and on the enamel in distal box. The teeth were randomly divided into 4 groups with 10 teeth in each and restored as follows: Group 1: light-cure GLASS IONOMER, Group 2: light-cure GLASS IONOMER with CERANA, Group 3: composite resin, Group 4: composite resin with CERANA. The high intensity program (HIP) was used for light-curing. After thermocycling (1000 cycles, 5-55oc) and load cycling (250000 cycles), micro leakage was evaluated by “dye penetration” technique. Data were statistically analyzed by Ordinal regression and Wilcoxon at significance level of 95%.Results: No statistically significant differences were found between the groups with and without CERANA. MICROLEAKAGE at the dentin margin was greater than that of the enamel margin significantly.Conclusion: Use of CERANA with HIP does not reduce MICROLEAKAGE at gingival margin in class II restorations. However, the effectiveness of CERANA with other restorative techniques and light curing methods needs to be assessed in further studies.
