BACKGROUND
The aim of the study is to determine the distribution, location, diameter, and distance measurements of Canalis Sinusosus (CS) in relation with age and sex.
METHODS
300 Cone-Beam Computed Tomography (CBCT) images were evaluated. The distance between CS and nasal cavity floor (NCF), buccal cortical bone margin (BCM), alveolar ridge (AR), respectively.The presence of CS smaller than 1 mm, and the diameter of CS larger than 1 mm were determined. Accessory canals (AC) were classified according to their position relative to the teeth.
RESULTS
435 CS with a diameter of at least 1 mm and 142 CS < 1 mm were identified. The most frequently observed location of CS was the region of the right central incisors. The mean diameter of the canals ( CS ≥ 1) was 1.31 ± 0.19 on the right side and 1.29 ± 0.17 on the left side. No gender differences were found in canal diameter were observed (p > 0.05). There was no significant difference between men and women in the distance between CS and the NCF on the right side, and a significant difference was found in the distance of CS-NCF on the left side (p = 0.047). There were no significant differences between age groups in all parameters.
CONCLUSION
CBCT is a useful tool for identifying CS. Location and diameter of ACs could not be associated with a specific age group or sex.
背景
本研究旨在确定与年龄和性别相关的窦腔（Canalis Sinusosus，CS）的分布、位置、直径和距离测量值。
方法
对 300 例锥形束 CT（Cone-Beam Computed Tomography，CBCT）图像进行评估。测量 CS 与鼻腔底（nasal cavity floor，NCF）、颊侧皮质骨缘（buccal cortical bone margin，BCM）、牙槽嵴（alveolar ridge，AR）之间的距离。确定直径小于 1mm 的 CS 及直径大于 1mm 的 CS 的存在情况。根据相对牙齿位置对副根管（accessory canals，AC）进行分类。
结果
确定了 435 个直径至少为 1mm 的 CS 和 142 个 CS＜1mm。CS 最常见的位置是右侧中切牙区域。直径大于 1mm 的 CS 右侧平均直径为 1.31±0.19mm，左侧平均直径为 1.29±0.17mm。未发现性别间的根管直径存在差异（p＞0.05）。右侧 CS 与 NCF 之间的距离在男性和女性之间无显著差异，而左侧 CS-NCF 之间的距离存在显著差异（p=0.047）。各参数在不同年龄组之间无显著差异。
结论
CBCT 是识别 CS 的有用工具。AC 的位置和直径不能与特定的年龄组或性别相关联。
