Biodentine versus Mineral Trioxide Aggregate versus Intermediate Restorative Material for Retrograde Root End Filling: An Invitro Study
Objective The aim of this study was to evaluate the marginal adaptation of Biodentine in comparison with Mineral Trioxide Aggregate ( MTA ) and Intermediate Restorative Material ( IRM ) , as a root end filling material , using Scanning Electron Microscopy ( SEM ) . Material s and Methods : Thirty permanent maxillary central incisors were chemo-mechanically prepared and obturated . Three millimetres of the root end were resected and 3 mm retro cavity preparation was done using ultrasonic retrotips . The sample s were r and omly divided into three groups ( n=10 ) and were restored with root end filling material s : Group I – MTA , Group II – Biodentine , Group III – IRM . The root ends were sectioned transversely at 1 mm and 2 mm levels and evaluated for marginal adaptation using SEM . The gap between dentin and retro filling material was measured at four quadrants . The mean gap at 1 mm level and 2 mm level from the resected root tip and combined mean were calculated . The data were statistically analyzed , using one-way ANOVA and Tukey ’s HSD post hoc test for intergroup analysis and paired t-test for intragroup analysis . Results : The overall results showed no statistically significant difference between MTA and IRM but both were superior when compared to Biodentine . At 1 mm level there was no statistically significant difference among any of the tested material s. At 2 mm level MTA was superior to both IRM and Biodentine . Conclusion : In overall comparison , MTA and IRM were significantly superior when compared to Biodentine in terms of marginal adaptation , when used as retro grade filling material
On the basis of available evidence , MTA presented good marginal adaptation to dentine walls .
