“…The three-dimensional obturation of the root canal system has been widely accepted as one of the key factors for successful endodontic treatment. 1,2 Obturation with inadequate apical sealing can cause microleakage due to voids or gaps in the root canal which allow the entry of oral microorganisms, thus leading to endodontic treatment failure. 2,3 A frequently used obturation material that has become the standard material to date is gutta-percha in combination with a root canal sealer.…”

Obturation with a sealer material that provides an adequate apical sealing ability is required to prevent endodontic treatment failure due to microleakage. However, there are no sealers that meet all the physical and chemical properties to be able to hermetically seal the root canal system to date. Various sealer materials have been developed in recent years including the use of bioceramic materials which are claimed to have excellent biocompatibility to tissues. This study aimed to compare the apical sealing ability of bioceramic-based and zinc oxide eugenol (ZOE)-based sealer in root canal treatment. A total of 27 extracted mandibular premolars were decoronated to the standard root length of 14 mm. The root canals were prepared with a crown-down technique using manual instrument to file F3 (30/.09). The samples were then divided into three groups: obturation with bioceramic-based sealer (n=9); ZOE-based sealer (n=9); and control group (n=9). Microleakage was measured using a dye penetration method with 1% methylene blue and observed under stereomicroscope at x20 magnification. The mean of the maximum penetration length from the lowest to the highest was found in the bioceramic-based sealer group (0.825 mm), the ZOE-based sealer group (3.850 mm), and the control group (4.444 mm). One-way ANOVA test showed a significant difference in the maximum penetration length between the three groups (p<0.05). The post hoc LSD test showed a significant difference in the maximum penetration length between the bioceramic-based and ZOE-based sealer groups (p<0.001). Obturation with bioceramic-based sealer provides a better apical sealing ability than that with ZOE-based sealer.

Aim: to compare the push out bond strength of the root canal filling with epoxy resin-based (Adseal), MTA-based (MTA Fillapex) and Bioceramic-based (Endosequance BC) sealers. Materials and Methods:Forty five extracted mandibular human first premolars with straight fully formed roots were selected for this study and were de-coronated at 17 mm from the apex. All root canals were prepared by using the ProTaper Universal Ni Ti rotary system in a crown down manner up to F4 according to manufacturer's instruction to the their working length. The canals were irrigated with 17% EDTA to remove the smear layer and the final rinse was performed with 5 mL 5.25% sodium hypochlorite. The roots were randomly assigned to three groups, fifteen for each (n=15). Adseal, MTA Fillapex and Endosequence BC sealers were used with gutta percha size F4 by lateral condensation technique for groups I, II and III respectively. All roots stored in 100% humidity at 37ºC for one week for completing setting of sealers. The roots were embedded in self cure acrylic resin, and transversely sectioned perpendicular to the long axis of the root 2 mm thickness slices. Apical diameter of 0.88 ± 0.02 mm in all slices were selected for the pushout test by universal testing machine. The dislodging force was measured in Newton for all slice samples and tabulated. Push out bond strength (MPa) for every slice sample is calculated and the three groups were compared. The slices were then examined under stereomicroscope and categorized into adhesive, cohesive or mixed type of bond failure mode. The data were tabulated and statistically analyzed.Results: Endosequence bioceramic represented the highest bond strength followed by Adseal then MTA Fillapex which represented the lowest bond strength with a significant difference between them at P≤0.05. Comparison between Adseal and Endosequence bioceramic groups and between MTA Fillapex and Endosequence bioceramic groups showed a significant difference between them at P≤0.05 with higher bond strength of Endosequence bioceramic sealer. Adseal represented higher bond strength than MTA Fillapex with no significant difference between them at P≤0.05. Comparison between the three tested groups of sealers regarding the bond failure categories showed no significant difference between them at P≤0.05. (1708) Recently, MTA Fillapex (Angelus, Londrina, PR, Brazil) is MTA-based sealer presented in a paste-paste system and composed of resins, bismuth oxide, silica nanoparticles, and pigments. It is a modification of the MTA original formulations to improve the characteristics such as good radiopacity, flow, setting time, alkaline pH and adhesion, Conclusion: Within the limitations of this study, Endosequence bioceramic sealer show promising results as root canal sealer and exhibited a greater resistance to push out than MTA Fillapex and epoxy resin-based sealer (Adseal) with gutta-percha as a root canal filling.
