objective: This study evaluated the influence of shapes of coronary opening on the localization of root canals in lower incisors. methods: It were used 32 teeth extracted from humans, being 16 with a single canal and 16 with two root canals that received, initially, conservative oval coronary opening, followed by random setting on mannequin, for clinical evaluation of number of root canals by two specialists. After that, the openings were enlarged to non-conservative triangular shape, being submitted to a second clinical evaluation regarding the number of root canals. results: On the examination of the conservative opening, the examiners 1 and 2 obtained, respectively, 15(94%) and 14(87%) scores for the teeth with one canal, with none (0%) and 5 scores (31,2%) for the teeth with two canals. After enlarging the opening, the examiners 1 and 2 obtained, respectively, 16 scores (100%) in cases with one canal, with 5 (31,2%) and 10 (62%) scores in cases with two canals. Between the examiners, on the non-conservative opening it was obtained Kappa = 0,456 and, on the conservative, Kappa = 0,629, determining mild concordance. According to results, the non-conservative triangular coronary opening lead to a greater percentage of scores on the localization of canals of lower incisors than the oval conservative opening, being this difference statistically significant (p < 0,05).
