PURPUSE: To investigate the canal morphology of bilateral mandibular first premolar using cone-beam CT (CBCT). METHODS: Ninety-seven CBCT images of bilateral mandibular first premolar were selected . The images were analyzed with NNT software for the number and morphology of canal, groove, position of bifurcation and symmetry of bilateral canal classification. RESULTS: The canal configuration of mandibular first premolar was type I :83.5%, type III:3.6%, type V:8.8% and C-shaped canal:4.1% by Vertucci's classification. The incidence of groove in complicated canal (75%)was obviously higher than single canal (3.7%). 56.3% of complicated canal bifurcated in middle third, and 31.3% in apical third. 93.8% of mandibular first premolar had bilateral canal symmetry, the symmetry rate of single canal (95.2%) was higher than complicated canal (66.7%). CONCLUSIONS: CBCT can provide accurate information of canal system, the canal anatomy of mandibular first premolar is complex. Supported by Research Fund of Science and Technology Commission of Shanghai Municipality(08DZ2271100). [ABSTRACT FROM AUTHOR]
