In Vitro Evaluation of Microleakage And Resin Tag Formation for Resin Cement of Composite Inlay
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 11
Abstract
Aim:The aim of the study was to assess the microleakage level and subsequent resin tag formation of various luting agents used to lute inlays. Methodology:Standardized cavity preparation with 4mm length, 3mm width and 1.5mm depth were prepared on buccal surface, 2mm above and 2mm below the cementoenamel junction. Impression of the prepared cavity was made with poly vinyl siloxane and inlay was made in the laboratory. Then the inlay was cemented and the following groups were made: Group 1: total etch, bond, lute with Rely X ARC. Group 2: enamel etch, lute with Rely X U100, Group 3: total etch, bond, lute with Rely X U100, Group 4: enamel etch, lute with Rely X U 200, Group 5: total etch, bond, lute with Rely X U200 and Group 6: control group. The resin cements were used as per the manufacturer’s instructions. Microleakage evaluation was done and resin tag formation was assessed using scanning electron microscopy and the results were tabulated. Results:Total etch U200 shows the least microleakage level both in the enamel and cemental margins, whereas the enamel etch U100 shows the maximum microleakage in both the levels. Total etch U200 shows the maximum amount of resin tag formation in the coronal dentin level whereas enamel etch U 200 shows the maximum resin tag formation in root dentin level. Conclusion:It can be concluded that total etch Rely X U200 produces the low microleakage when the cavity is pretreated by etching and bonding. Also the resin tag formation is maximum for total etch Rely X U200 which contributes to better bonding and low microleakage levels.
