Comparative Study of Microleakage of Three Different Flowable Restorative Materials and Light-cure Glass Ionomer Cement in Class V Cavities: An In-vitro Study

Abstract

In vitro study was done to compare the sealing ability of 3 Flowable restorative materials (Flowable composite, Flowable compomer, Flowable ormocer) and a Light cure Glass-ionomer cement in class V cavities at occlusal and gingival margin after 24 hrs of dye immersion. Standardized class V cavities were prepared on the buccal aspect of forty extracted premolars. These 40 teeth were divided into 4 main groups. Group A (Flowable ormocer), Group B (Flowable compomer), Group C (Flowable composite) and Group D (Light cure Glass-ionomer cement). The samples were then sectioned bucco-lingually through the centre of restoration and examined under stereomicroscope for dye penetration. Flowable ormocer showed least microlenkage of all the material at occlusal and gingival margin after 24 hrs of dye immersion. Light cure Glass-ionomer cement showed the maximum micro leakage and lea st sealing ability of all the materials. Flowable ormocer with best sealing ability can be advocated for class V situations.
