Evaluation of Sealing Ability of Three Different Sealers, Bioroot RCS, Guttaflow II, AH Plus - An in-Vitro Study

This in-vitro study compared the sealing ability of three different sealers Bioroot RCS, Guttaflow II and AH Plus using glucose leakage model. The study was done on 45 extracted single rooted human mandibular premolars. The teeth were decoronated and instrumentation was done till size F3 using Protaper rotary universal system. The specimens were randomly divided into three groups based on the sealers used. All the specimens were obturated with F3 single cone and the sealers were placed using the master cone. Group A single cone with Bioroot RCS, Group B single cone with Guttaflow II, Group C single cone with AH Plus. All samples were incubated for 1 week and microleakage measurement were made using glucose leakage model at an interval of 1 day, 1 week, 2 week and 4 week respectively. To compare the mean leakage values between the groups, repeated measures ANOVA followed by Tukeys HSD post hoc test were used. The three experimental groups showed significant difference in the leakage values at all test periods (p=0.05). At the end of 1 day, Bioroot showed better sealing ability followed by AH Plus and Guttaflow II. At all other time periods, Bioroot RCS had better sealing ability followed by Guttaflow II and AH Plus. At the end of experimental time period, it is concluded that none of the sealer provided complete seal but Bioroot RCS provided superior sealing ability compared to Guttaflow II and AH Plus.
