International Endodontic Journal, 43, 555–559, 2010. Abstract Aim To measure the minimum thickness of the distal (furcal) root dentine associated with the buccal and lingual canals of the mesial roots of mandibular first molars with different lengths. Methodology The mesial roots of 285 mandibular first molars were allocated into three groups according to their length: group I – long (24.14 mm ± 0.85), group II – medium (22.10 mm ± 0.65) and group III – short (19.97 mm ± 0.75). The minimum thickness of the distal (furcal) root dentine associated with the buccal and lingual canals of the mesial roots 2 mm below the furcation was measured. The distance between the buccal and lingual canals, and the depth of concavity in the distal surface of the mesial roots were also measured. anova and Tukey–Kramer were used to test for significant differences among the groups. Results The minimum thickness of the distal wall of the mesiobuccal canal was significantly different (P 0.05). The shortest distance between the mesiobuccal and the mesiolingual canals was observed in group III (P
