A comparative study of apical microleakage of different root canal sealers by apical dye penetration

Abstract

Abstract:Objective: This study was designed to compare the level of apical microleakage of root canal sealers; Acroseal, AH Plus, Endoflas FS and Endomethasone N, with laterally condensed gutta percha by level of apical dye penetration. Materials and Methods: Freshly extracted sixty permanent maxillary anterior teeth were divided randomly into four groups. Shaping and cleaning of teeth was done followed by obturation with gutta percha and four different root canal sealers. Samples were immersed in 2% methylene blue dye solution in individual dappen dish and stored in the solution for 30 days. The roots were split longitudinally with a chisel in two halves and observed under stereomicroscope. Apical microleakage measured from the apex to the most coronal extent of dye penetration. Results: Minimum microleakage was observed with AH Plus with mean value 2.140 mm, standard deviation 0.817. The maximum microleakage was observed with Endomethasone N with mean value 3.858 mm, standard deviation 1.840. There was no statistically significant difference in microleakage between Acroseal, AH Plus, and Endoflas FS. Endomethasone N showed highest level of microleakage than other three groups under the test condition, which was statistically significant. Conclusion: The microleakage was the lowest for the AH Plus and increased in the following order, Endoflas FS, Acroseal, Endomethasone N.

Apical sealing ability of chitosan nanoparticles in epoxy-resin-based endodontic sealer

“…The results of observations and dye penetration measurements in this study showed that in all groups of obturation material occurred apical microleakage. The results are in agreement with Ayer et al, 9 which states that all root canal obturation materials allow marginal infiltration and are not impenetrable.…”

Comparison of apical sealing ability between bioceramic and zinc oxide eugenol-based sealer during root canal treatment, in vitro

“…However, this did not apply to the ZOE-based sealers due to a longer setting time of around 24-36 hours, and nonacceptable flow rates. 14,15,22 The characteristics of the ZOE-based sealer caused some samples in this treatment group to experience an incomplete setting so the sealer material dissolved when the samples were immersed in the methylene blue dye. This assumption served as the basis for obtaining insignificant differences between the ZOE-based sealer and the control groups.…”

“…14 Several studies have been conducted to evaluate the apical sealing ability of bioceramicbased sealers. 1,15,16 However, there are no studies conducted to compare this material with the most commonly used standard sealer material, namely ZOE. This study aimed to compare the apical sealing ability of bioceramic-based and ZOEbased sealers in root canal treatment.…”

Comparative Assessment of Root Canal Sealer’s Apical Sealing Ability

“…Stereomicroscope was calibrated prior to observation, digital images of specimens had been captured using attached camera(OptikamB5, Italy) on a stereomicroscope (19) ,linear dye penetration leakage from root apex to the most coronal extent of dye penetration was measured in millimeters, and scored by scoring system (20) .Dye apical leakage was scored :Score 0: if there was no leakage, score 1: if leakage was less than or equal 0.5 mm, score 2: if leakage was from 0.51mm to less than 1 mm and score 3: if leakage was more than 1 mm (14) .…”
