The aim of this study was to evaluate the epidemiology of impacted and transmigrated mandibular canines in a large orthodontic population referred to the University of Turin.
Panoramic radiographs, intraoral photographs, and dental casts of 2119 patients referred to the Department of Orthodontics at the University of Turin, Italy, between 1995 and 2022 were reviewed. These patients were divided into two groups. Group A included 1479 patients found in the Dental School archive before 2017, more specifically between 1995 and 2017. These patients were examined in order to calculate the prevalence of impacted and transmigrated mandibular canines. From 2017 to 2022, the records of 640 new patients were examined (GROUP B) in order to calculate the incidence of these occurrences.
The prevalence of mandibular canine impaction in Group A was found to be 1.7%, with a total of 25 patients having mandibular canine impaction. A prevalence of 0.3% was found for mandibular canine transmigration (Group A). The incidence of mandibular canine impaction was found to be 2%, with a total of 13 patients with mandibular canine impaction (Group B). Mandibular canine transmigration was found in 1 of 640 participants (Group B).
Twenty-five of 1479 patients had impacted mandibular canines, resulting in a prevalence value of 1.7%. The incidence was found to be 2%, with 13 of 640 patients having impacted mandibular canines. These results show higher prevalence and incidence rates of mandibular canine impaction when compared with previously published data.
本研究旨在评估转诊至都灵大学的大量正畸患者中下颌阻生犬牙和异位萌出犬牙的流行病学情况。
回顾了1995年至2022年间转诊至意大利都灵大学正畸科的2119例患者的全景片、口内照片和石膏模型。这些患者被分为两组。A组包括2017年之前，更具体地说是1995年至2017年间在牙科学院档案中找到的1479例患者。对这些患者进行检查以计算下颌阻生犬牙和异位萌出犬牙的患病率。2017年至2022年期间，检查了640例新患者的记录（B组），以计算这些情况的发病率。
A组下颌犬牙阻生的患病率为1.7%，共有25例患者存在下颌犬牙阻生。下颌犬牙异位萌出的患病率为0.3%（A组）。下颌犬牙阻生的发病率为2%，共有13例患者存在下颌犬牙阻生（B组）。640名参与者中有1名出现下颌犬牙异位萌出（B组）。
1479例患者中有25例存在下颌阻生犬牙，患病率为1.7%。发病率为2%，640例患者中有13例存在下颌阻生犬牙。与先前发表的数据相比，这些结果显示下颌犬牙阻生的患病率和发病率更高。
