Comparative Evaluation of Apical Extrusion of Debris Using Hand and Rotary Assisted Instrumentation in Primary Single Rooted Teeth: An In-vitro Study
Abstract
Introduction: Extrusion of periapical debris is one of the common problem encountered during root canal treatment. As the endodontic instruments differ in terms of design and use, apical extrusion of debris may vary. Aim: To determine the quantity of debris extruded apically during various hand and rotary assisted instrumentation in extracted primary single rooted teeth. Materials And Methods: This in-vitro study was conducted in Department of Paediatric and Preventive Dentistry at Kannur Dental College, Anjarakandy, Kannur, Kerala, India, from December 2020 to May 2021. Four file systems were compared i.e, two hand files (Kedo SH and Protaper hand) and two rotary files (Kedo SG blue and Pro AF baby gold) among 60 therapeutically extracted single rooted primary teeth. The tooth was inserted into Eppendorf tube till cementoenamel junction, access opening was done, pulp extirpated, working length determined with 10 size k-file. After instrumentation, the tooth was washed with 10 mL of distilled water for debris collection. Tube was incubated at 70°c for drying and weighed to measure the collected debris. Data collected was analysed statistically using Independent t-test, One-way Analysis of Variance (ANOVA) and Least Significant Difference (LSD) Posthoc test for multiple comparison to compare between the groups were done. Level of statistical significance was set at p-value<0.05. Results: There was significant difference in the amount of debris collected between the hand file and rotary files (p-value<0.001), between Kedo SG blue and Pro AF baby gold (p-value<0.001), and Kedo SH hand file and Protaper hand file (p-value<0.05). Conclusion: Rotary files shows lesser amount of debris extrusion than the hand files. Comparing the four file system Kedo SG Blue file shows least periapical debris extrusion, the second least is Pro AF Baby Gold (rotary), then Kedo SH hand file and last Protaper hand file.
