Abstract
Objective To investigate the morphology of the maxillary first premolar of youth and junior in Chengdu region by cone beam computed tomography (CBCT) three-dimensionally (3D) reconstruction and to provide anatomic data and therapy basis. Methods One hundred and twenty maxillary first premolar were subjected to standardized CBCT and collected. From CBCT data, teeth were tissue segmented and then three-dimensionally (3D) reconstructed. The 3D reconstructed models were measured including many dental anatomy index measurements. Using SPSS software, the data were analyzed. Results CBCT images created good three-dimensional dental model of maxillary first premolars. The anatomic data between the right and left position of the same gender had no statistically significant differences. Between difference genders, the data including depth of dental crown, the ratio of height of dental crown and length of dental root, length of dental root had no statistically significant differences. But there was a significant difference between the other data. Conclusion The anatomic data of the maxillary first premolar may provide some therapy basis for clinical treatment, education and scientific research in dental clinic.关键词
