doi:10.13701/j.cnki.kqyxyj.2018.07.013

Abstract

Abstract: Objective: To measure the furcation anatomy of mandibular first molar with cone beam computed tomography, and to provide theoretical data for the diagnosis, treatment, and prognosis of furcation involvement. Methods: Cone beam computed tomography images of 203 mandibular first molars were collected.The length of root trunk and the width of 2mm under the root furcation opening were recorded and analyzed. Results: The length of the root trunk was (3.06±0.71)mm larger than that of the buccal (2.48±0.74)mm. The width of 2mm under the root furcation opening in the buccal side (1.63±0.55) mm was larger than that in the lingual side (1.08±0.46) mm (P<0.05). There was no significant difference between the length of root trunk and the width of 2mm under the root bifurcation opening in different gender. Conclusion: Compared with the buccal side, the width of 2mm under the root furcation opening in the lingual side of the mandibular first molar was narrower and the root trunk was longer.
