OBJECTIVE: To histologically evaluate the behavior of the subcutaneous tissue of rats after placement of polyethylene tubes filled with calcium hydroxide-based root canal sealers (SealapexTM, ApexitTM e Sealer 26TM). STUDY DESIGN: The study employed 60 rats, which were divided into eight groups, being four experimental groups with 10 rats each, and four control groups with five rats. Analysis was conducted at 48 hours, 7, 21 and 60 days. RESULTS: Histological analysis revealed that all sealers were irritant; however, the intensity varied between each sealer and as a function of time. At the initial periods (48 hours and seven days), all materials demonstrated similar outcomes, with inflammatory reaction from severe to moderate, respectively. At the final periods (21 and 60 days), the tissue reactions to the implants containing SealapexTM displayed an active status yet with regression, compared to the ApexitTM and Sealer 26TM. The control groups exhibited less inflammatory cells than the experimental groups, keeping a reaction status with regression. CONCLUSIONS: The results achieved in this study revealed that the SealapexTM sealer was the most compatible, followed by ApexitTM and Sealer 26TM.

Root Canal Sealers

Utilisation of root canal sealers to perform obturation procedures is an endorsed method in endodontics and has an indispensable role in the success of treatment. The objective of this study was to explore the pediatric dentists’ preference for root canal sealers for obturating permanent teeth. 360 permanent teeth with gutta-percha obturation done by pediatric dentists were analyzed for the study. The variety of root canal sealers that are utilised for obturating the permanent teeth by pediatric dentists were assessed. The data were obtained from a patient management software. Chi-square test was performed. Out of the 360 permanent teeth, 186 teeth were obturated using resin-based sealers, 101 teeth using zinc oxide eugenol-based sealers and 73 teeth were obturated using calcium hydroxide-based sealers, with statistically significant difference between the three materials (P<0.05). Based on the findings of the present study, resin sealers followed by zinc oxide eugenol sealers and calcium hydroxide sealers were more preferred by pediatric dentists for root canal therapy in permanent teeth.
