An In Vitro Study of Sealing Ability of Commercially Available Root Canal Sealers

Abstract

Objective: The current study aimed to explore the sealing ability of commercially available root canal sealers after obturation by using stereomicroscope. Study Design: Experimental laboratory-based study. Place and Duration of Study: The study was conducted at Zoology Department, National Centre of Excellence in Geology and Department of Pathology at College from 10 January 2021 to 31 March 2022. Materials and Methods: Teeth used in this study were divided randomly into four experimental (fourcommercially available sealers) and one control group (only gutta percha without using sealer) (n=10) denoted by EG1, EG2, EG3, EG4 and CG5 respectively. After obturation, specimens were coated with varnish except for 1-2mm of apical area and immersed in 2% methylene blue for 1 week. Specimens were analyzed using Stereomicroscopy, Scanning electron microscopy and Energy Dispersive X-ray Analysis (SEM, EDX). Kruskal Wallis and Mann-Whitney U-tests were employed to measure statistical significance. Results: Fifty percent samples of Endomethasone sealer had a score of 2 and the rest score 3. Sixty percent of Sealapex sealer had score of 2 and Forty (40) percent had score of 3. Fifty percent of Adseal sealer had score of 2 and remaining fifty (50) percent of Adseal sealer had score of 3. Fifty percent of AH Plus sealer had score of 2.Forty (40) percent had a score of 1 and remaining ten percent had score of 3 (Table. I). Conclusion: AH Plus proves to have better sealing ability with minimal dye penetration when compared to other endodontic sealers.
