The current study aimed to evaluate the severity and treatment difficulty of impacted maxillary canines and their relationship with gender, age group, and bucco-palatal position.
A retrospective cross-sectional study was conducted from 2017 to 2021. Patients' data and panoramic radiography were obtained from the orthodontic clinic at King Saud University's Dental University Hospital in Riyadh, Saudi Arabia. The severity factors and treatment difficulty index were used to assess the impacted maxillary canines. Statistical analyses were performed utilizing a chi-square test for categorical variables and an independent -test for numerical variables, and a -value of ≤0.05.
There were 171 impacted maxillary canines in total, with a female-to-male subject ratio (11:8) and a mean age (18.7 years). Overall, 77.2% of impacted upper canines were found to be palatal. The severity of canine impaction parameters showed no significant sex or age group predilection. Buccally impacted maxillary canines were characterized by a preferable angulation to the midline, compared to the palatally impacted maxillary canines ( = 0.012). The horizontal overlap of the impacted maxillary canine cusp tip revealed a significant association with the bucco-palatal position of the impacted canine ( < 0.001). Palatal impaction was located more frequently in sectors 3 and 4. Male patients were found to have a higher total score in terms of the treatment difficulty index relative to females ( = 0.046).
Despite the severity parameters having revealed no significant gender predilection, males were found to have higher treatment difficulty in maxillary canine impaction than females. The severity of the palatally impacted canine is greater than that of buccal impaction in terms of angulation to the midline and horizontal overlap.
本研究旨在评估上颌埋伏尖牙的严重程度和治疗难度及其与性别、年龄组和颊腭位置的关系。
本研究为 2017 年至 2021 年进行的回顾性横断面研究。从沙特阿拉伯利雅得的沙特国王大学牙科大学医院的正畸诊所获取患者数据和全景片。使用严重程度因素和治疗难度指数来评估上颌埋伏尖牙。使用卡方检验进行分类变量的统计学分析，使用独立样本 t 检验进行数值变量的统计学分析，α 值≤0.05。
共有 171 颗上颌埋伏尖牙，女性与男性的比例为 11:8，平均年龄为 18.7 岁。总体而言，77.2%的上颌埋伏尖牙位于腭侧。埋伏尖牙的严重程度参数显示性别或年龄组无明显偏好。与腭侧埋伏尖牙相比，颊侧埋伏尖牙的角度更偏向中线（ = 0.012）。埋伏尖牙牙尖的水平重叠与埋伏尖牙的颊腭位置显著相关（ < 0.001）。腭侧埋伏尖牙更多位于 3 区和 4 区。与女性相比，男性的治疗难度指数总分更高（ = 0.046）。
尽管严重程度参数显示性别无明显偏好，但男性上颌埋伏尖牙的治疗难度高于女性。在与中线的角度和水平重叠方面，上颌埋伏尖牙的严重程度大于颊侧埋伏尖牙。
