Eficacia de irrigación de dos sistemas ultrasónicos y dos sónicos en la remoción de debris en dientes bovinos

Abstract

Introduction: Irrigation is an essential part of debridement as it allows cleaning of the root canal system. Current methods for removing smear layer are sonic and ultrasonic activation. Objective: To compare the effectiveness of irrigation between two ultrasonic and two sonic systems in removing debris in bovine teeth. Materials and methods: An in vitro experimental study was performed using 92 bovine teeth sectioned at 16 mm in length, the samples werewere instrumented with Flexofile k files up to a diameter of #60,The teeth were divided and a groove was prepared in the apical third and filled with dentin remains, the halves were reassembled and 4 groups were formed (n= 23), group 1= ultrasonic irrigation (Newtron), group 2= ultrasonic irrigation (Ultra X), group 3=Sonic Irrigation (Endo Activator)and group 4=Sonic Irrigation (Easydo activator)), each group was irrigated with 8ml ofNaOCl 5.25%, irrigant activation was 3 cycles of 20 seconds each. Result: Statistically significant differences were found between group 1 and group 3 (p-value = 0.045 < 0.05) and between group 1 and group 4 (p-value = 0.004 < 0.05). Significant differences were also found between group 2 and group 4 (p-value = 0.008 < 0.05). Conclusions: Both ultrasonic systems demonstrated greater efficacy in removing debris in bovine teeth compared to sonic systems.
