ABSTRACT
AIM: The current study aimed to evaluate the penetration depth and sealing ability of three different endodontic sealers.
MATERIALS AND METHODS: A total of 60 extracted human mandibular premolars for orthodontic reasons with a single canal were divided randomly into three groups of 20 samples-Group I: Tubli-Seal [zinc oxide-eugenol (ZOE)-based sealer], group II: Endosequence [bioceramic (BC) sealer], group III: AH Plus (epoxy resin-based sealer). At the coronal, middle, and apical thirds, three transversal segments of 1 mm thickness were created using a low-speed precision IsoMet cutter running at 200 rpm while being continuously cooled by water. Following a gold-palladium sputtered coating, these slices were seen at ×1000 magnification using a scanning electron microscope (SEM). The gaps in between the sealer and the canal wall were measured by analyzing images. Data was recorded and statistically analyzed.
RESULTS: The maximum sealing ability was found in Endosequence BC sealer i.e., 3.96 ± 0.16 followed by AH Plus sealer i.e., 2.32 ± 0.08 and Tubli-Seal sealer i.e., 1.04 ± 0.10. On intergroup comparison at coronal third; a statistically significant difference was obtained between Tubli-Seal sealer vs Endosequence BC sealer and Endosequence BC sealer vs AH Plus sealer. At middle and apical third, significant difference was obtained between Tubli-Seal sealer vs Endosequence BC sealer, Tubli-Seal sealer vs AH Plus sealer and Endosequence BC sealer vs AH Plus sealer (p < 0.001).
CONCLUSION: On conclusion, according to the current investigation, Endosequence BC sealer had the best sealing ability, followed by AH Plus sealer and Tubli-Seal sealer.
CLINICAL SIGNIFICANCE: The effectiveness of endodontic therapy depends on proper root canal closure. There are many endodontic sealers available; finding easy-to-use and effective items is crucial to providing quality patient care. When a root canal system is fully sealed, oral pathogens cannot colonize and re-infect the root and periapical tissues. How to cite this article: Mohan D, Lahiri B, Sreenivasalu PKP, et al.
