Abstract:
The aim of this study was to evaluate the sealing ability of a new organically modified ceramic, Ormocer, in comparison with MTA as a root-end filling material using a dye penetration technique. Twenty-eight obturated human anterior teeth were divided into 4 groups. Each root was apically resected. Nail polish was applied to the root surfaces of the first 3 groups. Apical cavity preparations were performed on all teeth. The retropreparations were filled either with-MTA (group 1, n=10 teeth), Ormocer (group 11, n=10 teeth), or only covered with nail polish (group III, n=4 teeth). In group IV (positive control, n=4 teeth) no retro-filling and no nail polish was applied. The specimens were suspended in methylene blue dye for 7 days. The teeth were sectioned longitudinally and the depth of linear dye penetration was measured. Theresults indicated that MTA had significantly (p-0.022) less microleakage than Ormocer. MTA is superior to Ormocer in preventing microleakage when used as a root-end filling material.
