FERNANDES2, 1Universidade Braz Cubas, Mogi das Cruzes, Brazil, 2Centro Universitário Nove de Julho, São Paulo, Brazil Objective: evaluate in vitro the influence of three chemical substances on the accuracy of Bingo 1020® apex locator. Methods: Thirty canals of single-root teeth were measured, using a file, from coronal reference to the foramen (real length). Electronic measurement was carried out by the apex locator, in canals filled with 17% EDTA (GI); 1% NaOCl (GII); and 0,2% chlorhexidine (GIII), after the roots were embedded in alginate. Data were treated by ANOVA (P≤0,05) and Tukey's test (P≤0,05). Results: Real measurements were coincident to electronic ones in 20% of the specimens from group I; 80% of the specimens from group II and in 90% of the specimens from group III. Conclusion: Among the tested substances, chlorhexidine showed the smallest interference on the accuracy of the electronic device, followed by NaOCl and by EDTA. | ||
