“…AH Plus (0.893 mm) performed significantly better than Sealapex (3.136 mm) with less depth of dye penetration due to its low solubility, dimensional stability and adhesiveness the sealer that provides a sufficient seal and adequate sealing ability than that of Sealapex group [10].…”

Introduction: The purpose of the root canal obturation is to provide a hermetic seal, that inhibits the microleakage and canal reinfection, thus the health of the periapical tissues can be preserved. It has been observed that the sealer used during endodontic therapy has a direct link with the longevity of the treatment and the occurrence of postoperative pain. Aim: The goal of the present study was to assess microleakage in extracted teeth of four separate endodontic sealers (AH Plus, Sealapex, MTA Fillapex, and Ceraseal) using the dye penetration method. Materials and Methods: In this in-vitro study, 84 freshly extracted single-rooted teeth were endodontically treated and obturated using four different sealers and divided into four groups along with two control groups based on the sealer used. Microleakage was checked in apical sections using the dye penetration method under the stereomicroscope. Results: The maximum dye penetration was seen in Sealapex whereas the least microleakage was shown by Ceraseal endodontic sealer. Conclusion: Maximum microleakage was seen with calcium hydroxide based (Sealapex) while the least microleakage was noticed in bioceramic based (Ceraseal) sealer group.

“…Over 80% of microleakage studies have opted for dye penetration as the assessment method of choice [ 1 , 2 ]. In the present study, linear dye penetration was measured in millimeters to yield a true, precise and quantitative microleakage assessment.…”

“…The better sealing ability of Sealapex can be credited to the materials’ property of volumetric expansion. On the contrary, it is argued in the literature that, since Sealapex undergoes volumetric expansion via water absorption to attain an initial acceptable seal, this paradoxically causes the material to become soluble, thus deteriorating its apical seal over time [ 1 , 2 ]. The solubility of Sealapex has always been a source of contention and criticism within the dental community.…”

“…Successful endodontic therapy aims to create a favorable environment for healing of periapical tissues via complete canal disinfection and formation of a three-dimensional apical seal. The quality of an apical seal is assessed by measuring the amount of apical microleakage that presents within and in-between the endodontic materials [ 1 , 2 ]. Obturation materials and techniques that facilitate increased penetration of sealer and gutta-percha (GP) into canal complexities are regarded as an effective mechanism in preventing microleakage and subsequent treatment failures [ 3 ].…”

Exploring the Most Effective Apical Seal for Contemporary Bioceramic and Conventional Endodontic Sealers Using Three Obturation Techniques

Background and Objective: Despite a plethora of studies conducted to date, researchers continue to investigate the best sealer and obturation technique combinations. The aim of this study is to compare the apical seal provided by two bioceramic sealers (Endoseal and Endosequence) with that provided by a calcium hydroxide sealer (Sealapex), and to evaluate the effect of different obturation techniques (cold lateral condensation, continuous wave compaction and single cone) on the apical seal under a stereomicroscope. Materials and Methods: A total of 110 single-rooted mandibular premolar teeth were decoronated, cleaned and shaped using the Endosequence filing system to tip size 30/0.04 taper. Canals were irrigated with 5.25% NaOCl and 17% EDTA. The samples were randomly divided into 11 groups (9 experimental and 2 control groups) according to the designated sealer and technique. Samples were stored in an incubator for 7 days at 37 °C under 100% humidity. Samples were coated with nail varnish except for apical 2 mm and vertically placed in 0.2% rhodamine B dye solution for 48 h. Samples were split longitudinally and viewed under a stereomicroscope at 40× magnification. Results: Insignificant results were obtained between obturation techniques (p = 0.499) whereas statistically significant results were attained based on the type of endodontic sealer (p < 0.001). The overall lowest mean apical microleakage and best sealing ability was demonstrated by Sealapex (2.59 ± 1.20 mm) and amongst techniques by continuous wave compaction (3.90 ± 2.51 mm). Conclusions: Endosequence produced the best apical seal with the continuous wave compaction technique, whereas Endoseal did so with the bioceramic-coated single-cone technique. For the Sealapex sealer, the most effective apical seal was observed using cold lateral condensation. The quality and effectiveness of apical seal differed with the type of endodontic sealer and obturation technique used, and vice versa.

“…The 3-dimensional lling of the cleaned and shaped root canal system is crucial to the success of root canal treatment (1,2). To enhance the effect of root canal lling, sealers must penetrate into the dentinal tubules (3)(4)(5). The residual smear layer produced by mechanical instrumentation can act as a barrier to decrease sealer penetration into the dentinal tubules and might promote bacterial invasion of the dentinal tubules (6-9).…”

This study compared the effects of different irrigation systems on sealer penetration at the root apex. Forty-two single-rooted teeth were prepared and randomly divided into three groups (n = 14): group 1: needle irrigation (NI); group 2: passive ultrasonic irrigation (PUI); and group 3: Easydo Activator (EA). A solution of 3% sodium hypochlorite (NaOCl) was used for irrigation. Nine teeth in each group were filled with AH Plus sealer mixed with CY5 fluorescent dye and a single gutta-percha cone. The sealer penetration area, maximum penetration depth and percentage of sealer penetration at 5 mm and 1 mm from the apex were analyzed by confocal laser scanning microscopy (CLSM). The remaining 5 teeth in each group were subjected to test smear layer scores by scanning electron microscopy (SEM). The CLSM evaluation showed that increases in the area, depth and percentage of sealer penetration were detected at 1 mm and 5 mm from the root apex in the PUI group compared with the NI group, and greater increases were observed in the EA group (P < 0.05). The SEM experiment showed that the lowest scores for the smear layer and debris removal were achieved by the EA group when compared with the PUI and NI groups (P < 0.05). Our study supports EA was superior to PUI and NI regarding sealer penetration at the root apex during endodontic treatment, and it could provide a new technical idea for clinical root canal therapy.

Evaluation of Microleakage in Single-Rooted Teeth Obturated with Thermoplasticized Gutta-Percha Using Various Endodontic Sealers: An In-Vitro Study

Abstract: Obtura II-AH plus sealer was a better combination for obturation as it showed a lesser degree of microleakage. Obtura II with Sealapex group showed higher microleakage, so this combination should be avoided in single-rooted teeth.
