To assess the relationship between dental follicle width and maxillary impacted canines' descriptive and resorptive features with three-dimensional (3D) cone-beam computed tomography (CBCT).
The study comprised 102 patients with cone-beam computed tomography 3D images and a total of 140 impacted canines. The association between maxillary impacted canine dental follicle width and the variables of gender, impaction side (right and left), localization of impacted canine (buccal, central, and palatal), and resorption of the adjacent laterals was compared. Measurements were analyzed with Student's -test, Kruskal-Wallis test, and Mann-Whitney statistical test.
According to gender, no statistically significant differences were found in the follicle size of the maxillary impacted canine between males and females ( > 0.05). Widths of the follicles were determined for the right and left impaction sides, and no statistically significant relation was found ( > 0.05). There were statistically significant differences between root resorption degrees of lateral incisors and maxillary impacted canine follicle width ( < 0.05). Statistically significant higher follicle width values were present in degree 2 (mild) resorption than in degree 1 (no) and degree 3 (moderate) resorption samples ( < 0.05).
No significant correlation was found between follicle width and the variables of gender, impaction side, and localization of maxillary impacted canines. Our study could not confirm that increased dental follicle width of the maxillary impacted canines exhibited more resorption risk for the adjacent lateral incisors.
通过三维（3D）锥形束 CT（CBCT）评估牙囊宽度与上颌埋伏尖牙的描述性和吸收特征之间的关系。
本研究纳入了 102 名接受锥形束 CT 3D 成像检查的患者和总共 140 颗埋伏尖牙。比较了上颌埋伏尖牙牙囊宽度与性别、埋伏侧（右侧和左侧）、埋伏尖牙定位（颊侧、中央和腭侧）和相邻侧切牙吸收之间的关系。使用 Student's t 检验、Kruskal-Wallis 检验和 Mann-Whitney U 检验对测量值进行分析。
根据性别，男性和女性上颌埋伏尖牙的牙囊大小无统计学差异（>0.05）。对右侧和左侧埋伏侧的牙囊宽度进行了测定，未发现统计学差异（>0.05）。侧切牙的根吸收程度与上颌埋伏尖牙牙囊宽度之间存在统计学差异（<0.05）。在轻度吸收（2 度）样本中，牙囊宽度的统计学值显著高于无吸收（1 度）和中度吸收（3 度）样本（<0.05）。
牙囊宽度与性别、埋伏侧和上颌埋伏尖牙定位等变量之间无显著相关性。我们的研究不能证实上颌埋伏尖牙的牙囊宽度增加会增加对相邻侧切牙的吸收风险。
