Introduction:The study compared accuracy of J Morita-Root ZX mini (multiple frequency based), Woodpecker gold V (multiple frequency based), Coltene Canal pro (multiple frequency based) apex locators with the irrigating solutions, NaOCl, Endosolv, Citric acid, HEBP. Methodology:The actual root canal length of teeth were measured using a 10 size K file under a dental operating microscope. The samples were mounted in alginate model and the electronic working length was recorded in both dry and wet (with irrigants).Variation in the readings of EALs after blockage was compared with actual length (measurement under microscope). The error was subjected to statistical analysis (ANOVA test and Post hoc Bonferroni test). Results:The mean overall (dry and wet canal) error for Root zx mini was 0.116 mm with maximum and minimum error range of:-2.1 to 1.5mm. The overall (dry and wet canal) mean error for Woodpex 5 was 0.305 within a range of: -1 mm to 1.80mm.The overall (dry and wet canal) mean error for Coltene canal pro was 0.271 within a range of : -2.100 to 1.80. Conclusion:Root ZX mini was the most accurate EAL amongst all the three EALs used in this study in both wet and dry conditions. Amongst the 4 irrigants used, all the three EALs recorded the highest deviation from actual length in presence of Citric acid.
Introduction: Endodontic management of immature permanent teeth is a challenge for both clinicians and researchers. Open apex is an unusual wide apical foramen that results due to multiple reasons such as incomplete development, extensive apical resorption, caries leading to pulpal necrosis or trauma before complete root formation, root-end resection, or due to over instrumentation. Aims: To prevent the risk of subsequent microbial contamination. Case Report: This article is a case report showing the management of open apex with MTA plug and a thermoplasticized Gutta Percha technique for obturation. Discussion: Traditionally, calcium hydroxide was used for inducing the formation of an apical barrier. Conclusion: Currently, biomimetic materials like mineral trioxide aggregate (MTA) and biodentin have shown promising results for apexification procedures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
