Comparison of the microleakage between two different flowable composite resin restorations with 8th generation bond system in Class II cavity: An in vitro stereomicroscopic study.
Comparison of the microleakage between flowable composite resins with 8th generation bond system.
Abstract
Introduction Marginal adaptability of composite resins is one of the prime factors for the success of class II cavity restoration. Materials and Methodology: Forty non-carious extracted mandibular molar with fully formed apices were collected and Class II box type cavities were prepared on both mesial and distal surfaces of every tooth using a new straight fissure diamond bur and high-speed airrotor handpiece. According to the type of restorative materials used, teeth were divided into Group I (n=20): Restored with SDR (Smart Dentin Replacement) and Group II (n=20): Restored with Tetric Eva Flow Bulk Fill. After 24 hours of storage in distilled water at 37˚C, the restored specimens were subjected to artificial aging by thermocycling. The teeth were then immersed in a 2% methylene blue dye for 24 hours. All samples were cut longitudinally through the center of the restorations with the help of an isomet diamond saw. The sections were then observed under a stereomicroscope at 25X for scoring the depth of dye penetration at cervical and axial walls toward the pulp. Results: Mean score of Group Ia is 0.4±0.83 and Ib was 0.55±0.88 respectively while the mean score of Group IIa was 0.75±1.118 and in IIb was 0.75±1.019 respectively. Microleakage was found to be highest in Group IIa and minimum in Group Ia. Conclusion: Use of a flowable composite SDR above and below the CEJ in Class II composite resin restorations showed good results.
