Evaluation of the Apical Sealing Ability of Bioceramic and AH Plus Root Canal Sealers – An In Vitro Study

Abstract

OBJECTIVE: Evaluation of apical sealing ability of Bioceramic and AH plus root canal sealers, an in-vitro study.METHODOLOGY: This in vitro non-probability convenient sampling study was conducted at the Department of Operative Dentistry, Liaquat University of Medical and Health Sciences, Jamshoro from June-December 2018. Fresh extracted 32 teeth were included and their crowns were sectioned at Cemento-Enamel Junction/service to obtain 12mm standard root length. The access cavity was gainedusing endodontic instruments. The teeth were divided into two groups, in Group A (n=16) MTA Bioceramic and in Group B (n=16) AH Plus was used as root canal sealers by single cone obturation technique. The obturated specimens were stored in humid conditions for one week. Analysis was done using SPSS version 20.RESULTS: Mean and standard deviation of dye leakage for Bioceramic were 2.25±0.9 whereas for AH Plus was significantly lower, 1.19±0.75. Teeth included in Group A were central incisors 37.5%, lateral incisors 18.8%, canine 12.5%, lower first premolars 12.5% and second premolars 6.3%, whereas Group B consisted of central incisors 18.8%, lateral incisors 12.5 %, canine 12.5%, lower first premolars 18.8 % and second premolars 6.3%. Dye leakage was higher in Group A compared to Group B with a significant P-value < 0.001.CONCLUSION: It can be concluded based on this study that AH Plus offers a better apical seal as compared to Bioceramic-based MTA Fillapex sealers.
