成都正常人群上颌前牙区鼻腭管相关解剖结构的锥形束CT研究
Cone-beam computed tomography evaluation of nasopalatine canal anatomy at maxillary anterior region in Chengdu normal population
摘要
Abstract
Objective To provide an anatomical guidance for surgical operations,we evaluated the general anatomical morphology of nasopalatine canal(NPC) and maxillary anterior region.Methods Seven hundred and twelve conebeam computed tomography(CBCT) images of normal people were collected.Three experienced oral radiologists used INFINITT software to evaluate the relevant parameters of the NPC and labial bone.Results Seven hundred and twelve subjects ranged in age from 5 to 80,including 306 males(43.0％) and 406 females(57.0％).The mean length of the NPC was (13.58±2.22) mm,the mean diameter was (3.37±1.58) mm and the mean thickness of labial bone was (7.63±1.50) mm.The ratio of the thickness between NPC and labial bone is 0.46±0.19,and the ratio of their length is 0.69±0.10.Conclusion The study revealed statistically significant differences in the diameter of the NPC,length of the NPC and thickness of the labial bone.The mean diameter of the NPC was shorter(P＜0.000 1) and the labial bone was thicker(P＜0.000 1) in children.We also found that the mean length and diameter of the NPC had a trend to become longer with age,while the labial bone became thinner.Additionally,our study showed that gender exerted a significant influence upon the NPC and the labial bone,with larger values in males than in females.关键词
