Radiographic Comparison Quality of Obturation Three Sealers Endoseal MTA, MTA Fillapex and Adseal in the Root Canal of Human Teeth

Background and purpose: To achieve a successful root canal treatment, it is necessary to have a sealer with ideal characteristics that seal the permanent filling of the tooth canal. Over time, various sealers with different compositions have been introduced to increase the obturation quality of tooth root canals, and many studies are still ongoing to find the ideal sealer. This study aims to evaluate the obturation quality of Endoseal MTA sealer based on the void and spreader track in the root canal using intraoral digital radiography (PSP) and compare it with Adseal and MTA Fillapex. Materials and methods: This laboratory study was conducted on 36 central maxillary single-canal permanent human teeth with the same shape and in the pre-clinic of the dental school of Mazandaran University of Medical Sciences. Root canal preparation was done with the Denco rotary system up to size F3 according to the manufacturer's instructions. During preparation, sodium hypochlorite 5.25% was used for washing, and finally EDTA 17% and sodium chlorite 5.25% were used to remove the smear layer. The teeth were dried with a paper cone. The samples were randomly divided into 3 groups and were filled with gutta-percha and sealers; MTA Fillapex, Endoseal MTA, and Adseal by lateral compaction method using Master Cone 35 and cone 20. After the sealers were set completely for 24 hours, PSP imaging was done with a parallel technique, buccolingually and mesiodistally, from the root canal of the teeth, and the presence of void and gaps in the form of spreader track in the three apical, middle and coronal regions, was evaluated with 3 independent observers. The data were evaluated with chi-square or Fisher's exact test, and items less than 0.05 were considered significant. Results: In the current study, the obturation quality of MTA Fillapex, Endoseal MTA, and Adseal sealers was investigated on 36 teeth based on void and gap in the form of spreader track. These evaluations were done according to the direction and location of the sealers. In these evaluations, Adseal sealer had the lowest and MTA Fillapex had the most prevalence of spreader track prevalence, although these differences were not significant based on the chi-square test and there was no significant difference between the prevalence of Spreader track among the three sealers. The void was observed only in the Endoseal group in coronal (mean: 0.5) and apical (mean: 0.7) areas. The results of the Chi-square test showed that th
