Microleakage of Different Restorative Materials in Class V Restorations: In-Vitro Study
Abstract: Microleakage is a major factor contributing in the occurrence of secondary carious lesions around restorations. This study aimed to evaluate the microleakage around class V restorations using different restorative materials. In this in vitro study, 32 standardized class V cavities were prepared on buccal and lingual surfaces of 16 human teeth (extracted within a period of 6 months) using bevelled conventional preparation, where occlusal margin was located at the enamel and cervical margin at the cementum/dentin level. Specimens were randomly divided into 4 groups (N= 8) for restoration with (A) GC Fuji II LC (Resin modified glass ionomer) (B) Prime&Bond universal + SDR plus (Smart dentin replacement) (C) FuturaU Bond + Admira Fusion Flow (Ormocer-based nanohybrid flowable composite) (D) Palfique universal bond + Palfique universal flow. After being stored in distilled water and finished, teeth were immersed for 24 hours in 2% methylene blue dye. Teeth were sectioned bucco-lingually and dye penetration on occlusal and cervical margins was scored using a stereomicroscope. The results were analyzed using Chi square test and Kruskal-wallis test (? = 0.05). There was statistical significant difference between microleakage at occlusal margin and at the cervical margin (p
