Assessment of the Sealing Ability and Penetration Depth of Different Endodontic Sealers: A Scanning Electron Microscope Study.

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.
