The aim of this study is to assess the morphology of nasopalatine canal (NPC) with cone beam computed tomography (CBCT).
A total of 460 subjects of both genders were subjected to CBCT with NewTom machine, and sagittal and coronal sections were used for evaluation of the shape of NPC and width of buccal cortical plate. Types of NPC were also assessed.
Of 460 subjects, males were 210 and females were 250. The difference was nonsignificant (p = 0.1). Type III canals were mostly seen in both males and females, followed by types I and II. The mean length of NPC in males and females showed statistical significant difference (p < 0.05). Males showed significantly higher diameter of nasal opening, oral opening, and width of the buccal bone plate over the oral opening as compared with females.
The exact location, morphology, and dimensions of NPC can be well visualized with CBCT. All findings were higher in males as compared with females.
The success of dental implant in maxillary anterior region may be affected by the approximation with NPC. The exact location and morphology play an important role for the correct placement of implant. Cone beam computed tomography is a useful tool providing three-dimensional images in all sections.
本研究旨在通过锥形束计算机断层扫描（CBCT）评估鼻腭管（NPC）的形态。
使用NewTom机器对460名男女受试者进行CBCT检查，利用矢状面和冠状面评估NPC的形状以及颊侧皮质骨板的宽度。同时评估NPC的类型。
460名受试者中，男性210名，女性250名。差异无统计学意义（p = 0.1）。III型管在男性和女性中最为常见，其次是I型和II型。男性和女性NPC的平均长度显示出统计学显著差异（p < 0.05）。与女性相比，男性的鼻口直径、开口直径以及开口上方颊骨板宽度明显更大。
CBCT能够很好地显示NPC的精确位置、形态和尺寸。与女性相比，所有测量结果在男性中均更高。
上颌前部区域种植牙的成功可能会受到与NPC接近程度的影响。精确的位置和形态对于种植体的正确植入起着重要作用。锥形束计算机断层扫描是一种在所有层面提供三维图像的有用工具。
