Abstract

Abstract

Objective To observe the number and variation of root and canal of mandibular first molar in Yunnan province by using cone-beam computed tomography (CBCT) , and to provide anatomical experimental basis for pulp treatment.Methods In this study, Cone-beam CT images were collected from 300 patients with a total of 600 mandibular first molars from imaging department of Yunnan Provincial Stomatological Hospital.The number of root and canals and the occurrence of distolingual root and the morphology of root canal were analyzed statistically.The root canal configurations were classified according to the method of Vertucci.Results CBCT image data of 600 mandibular first molars were obtained.The incidence of two-root was 71.2% (427/600) , and three-root was28.8% (173/600) .Two canals were found in 2.1% of mandibular first molars and 60.7% had three canals and36.8% had four canals.Most mesial roots were type IV configuration and most distal roots had a simple type I configuration and 100% of distolingual root was type Ⅰ.The incidence of distolingual root of population was 33.7% (101/300) .There was no significant difference between males and females (P>0.05) .71.3% (72/101) occurred bilaterally.The incidence of the right side of distolingual root was significantly higher than that on the left side (P<0.05) .Conclus ion The incidence of distolingual root is higher in the mandibular first permanent molar in Yunnan, and the incidence of right side is significantly higher than that of the left side. CBCT is easy to study the root canal, which can assist thetreatment of pulp and improve the success rate of root canal therapy.
