説明

<p>Abstract : Purpose : The purpose of this study was to evaluate the apical sealing of MTA-based root canal sealer (MTA-Fillapex, Endoseal) and resin-based root canal sealer (AH plus jet) as a control.</p><p> Materials and Method : A total of 72 plastic teeth (Thermafil training block) were prepared for the experiment. The remainder teeth prepared 7% tapered #25 canal. The six groups were separated and obturation by single cone technique and THERMA-PREP 2 with Guttacore. The sealing ability of MTA-based root canal sealers was evaluated by dye leakage test. A one-way analysis of variance (ANOVA) and Scheffe’s test were used to compare and identify any statistically significant differences at p<0.05.</p><p> Results : The sealing ability of MTA-based root canal sealers was significantly lower than that of AH plus jet. The sealing ability of MTA-Fillapex was better than that of Endoseal, although not significantly different from those of single GPP and/or THERMA-PREP 2 with Guttacore for each root canal sealer.</p><p> Conclusions : This study confirmed that the sealing ability of MTA-based root canal sealers was significantly lower than that of resin-based root canal sealer.</p>
