Anatomy and Clinical Significance of the Root Canal System of Maxillary First Premolars

Wang Huiming, Zhong Sheng, Huang XiaojingSchool of Stomatology, Fujian Medical University, Fuzhou 350004, China  
Objective The aim of this study was to investigate the root canal system of maxillary first premolar.Methods147 maxillary first premolars extracted were studied by observation directly, radiographs, and transparent specimen methods.Results Of all the teeth studied 69.39%(102/147) were found to have one root, 30.61%(45/47) were found to have two. About 53.06%(78/147) of apical foramens did not locate at their apices, and the mean deviation was (0.84±0.63)mm. In single rooted teeth ,32.35%(33/102)of their roots bended distalward. In the double rooted teeth, about 33.33%(15/45) of the buccal roots bended palatineward, of which the average curvature was(15.59±8.470)°; and about 30.2% (14/45) of the palatine roots bended buccalward, of which the average curvature was 16.62(16.62±5.19)°.Four types of root canal system were observed by radiographs, and six types were observed by transparent specimen methods. ConclusionThe root canal system of maxillary first premolars were very complex, and must be paid attention in our clinical practice.
