Root canal morphology of deciduous mandibular first molar was studied using roentgenographic and decalcification and clearing methods. Two groups of 15 teeth were formed. In the roentgenographic group, roots of the teeth were separated from the crown at the level of CEJ. Cut roots of the teeth were radiographed from both mesiodistal and buccolingual directions using separate IOPA films. In the decalcification and clearing group, teeth were decalcified and made transparent. Dye was injected later. The roots of the teeth were examined under 10 times for number, curvature, types and additional features of root canals. Deciduous mandibular first molar showed variability in root canal morphology. Four to five root canals were recorded. Majority of the teeth had 1-1 type of root canal anatomy, but 1-2 type anatomy was also reported. Straight, curved and S-shaped canal curvatures were recorded. Horizontal anastomosis, lateral canals and buccolingually broad root canals were also recorded.
