Title

IN VITRO COMPARISON OF MICROLEAKAGE OF NANOFILLED AND FLOWABLE COMPOSITES IN RESTORING CLASS V CAVITIES IN PRIMARY MOLARS

Pages

  47-51

Abstract

 Background: Composite resins undergo MICROLEAKAGE due to polymerization shrinkage particularly when located in cementum or dentin. The purpose of this study was to compare the MICROLEAKAGE of flowable and NANOFILLED COMPOSITEs in Class V cavities extending on to the root in PRIMARY MOLARs.Materials and Methods: Forty eight class V cavities in the cervical part of buccal and lingual surfaces of 24 intact mandibular second PRIMARY MOLARs were prepared, with occlusal margins on enamel and gingival margins on cementum. After restoring cavities randomly with nanofilled or FLOWABLE COMPOSITE by incremental technique, specimens were stored in distilled water for 24 hours, thermocycled, immersed in a basic Fuchsin solution for 24 hours and sectioned buccolingually. MICROLEAKAGE was evaluated according to the depth of dye penetration along the restoration wall using a stereomicroscope. Data were analyzed by Mann- Whitney U test at a significance level of 0.05.Results MICROLEAKAGE of flowable and NANOFILLED COMPOSITEs at the cervical margin showed no statistically significant difference, however occlusal margin in NANOFILLED COMPOSITE exhibited significantly less MICROLEAKAGE than FLOWABLE COMPOSITE (p=0.013).Conclusion: In contrast to occlusal margin, there was no statistically significant difference in MICROLEAKAGE between the 2 composites on the gingival margin. MICROLEAKAGE on the gingival wall was greater compared to occlusal wall for both composites.
