Eficacia de diferentes tipos de aguja de irrigación en la remoción de debris en dientes Bovinos

Abstract

Objective: Compare the efficacy of the open-end needle (Flat) with the notched open-end needle (Notched) and the closed-end needle with lateral ventilation (Side-port) in the removal of debris of the apical third on bovine teeth.

Materials and Methods: A transverse in vitro study was performed using 108 bovine teeth which were standardized to a length of 16mm and were apically prepared to a K # 60 file, were longitudinally divided and a groove was created in the apical third of the vestibular segment, which was filled with a mixture of debris and irrigant, the teeth were reassembled and distributed in three groups to be irrigated with 8ml of 5.25% sodium hypochlorite using three types of needles, finally dried with paper points . The teeth were disassembled for observation and take photographs of the grooves under the stereomicroscope at 30x. The evaluation of the effectiveness of debris removal was performed by two blinded and previously calibrated observers looking at the images obtained using the score described by van der Sluis. The tabulation and data analysis was performed in "SPSS vs.20" and the Chi Square test was performed
