摘要： 目的: 通过曲面断层片分析青岛市学龄儿童第一恒磨牙异位萌出的发病率、分布及严重程度。方法: 选取2020年8月1日~2022年12月10日于青岛市口腔医院儿童口腔科就诊,5~8岁的学龄儿童曲面断层片进行影像学分析,评估并统计第一恒磨牙异位萌出患儿的年龄、性别、异位萌出牙数、牙位及严重程度,使用SPSS 24.0软件进行统计学分析。结果: 在对8939例患儿回顾性影像学分析中,发现295例(3.31%)被诊断为第一恒磨牙异位萌出。男性(164例,3.4%)的发病率略高于女性(131例,3.2%)。上颌骨的发病率(84.4%)明显高于下颌骨(15.6%),二者比较差异有统计学意义(P<0.001);左侧(47.7%)与右侧(52.3%)发病率相似,二者比较无统计学意义(P>0.001)。双侧(63.1%)第一恒磨牙异位萌出比单侧(36.9%)更常见。重度和极重度的异位萌出在上颌骨比在下颌骨更常见(P<0.001)。结论: 第一恒磨牙异位萌出的发病率男性略高于女性,但二者比较差异无统计学意义;第一恒磨牙异位萌出好发于上颌骨且严重程度高于下颌骨,在左右侧颌骨的发病率大致相同。双侧第一恒磨牙异位萌出比单侧更为常见。

Abstract: Objective: To learn the incidence, distribution, and severity of ectopic eruption of first permanent molars of school-age children in Qingdao by panoramic radiographs. Methods: The panoramic radiographs of school-age children from 5-8 year-old were selected. These children came to the Pediatric Stomatology Department of Qingdao Stomatological Hospital from August 1, 2020 to December 10, 2022. The age and gender of the subjects and the tooth number, tooth location, and severity of ectopic eruption of the first permanent molar were counted by SPSS 24.0 software. Results: In 8939 cases, 295 cases (3.31%) were diagnosed as ectopic eruption of the first permanent molar. The prevalence of males (164 cases, 3.4%) was higher than that of female (131 cases, 3.2%). The incidence of maxilla (84.4%) was significantly higher than that of mandible (15.6%, P<0.001). The incidence of the left (47.7%) was similar to that of the right (52.3%, P>0.001). Bilateral (63.1%) ectopic eruption of the first permanent molar was more common than unilateral (36.9%). Severe and very severe ectopic eruptions were more common in the maxilla than in the mandible (P<0.001). Conclusion: The incidence of ectopic eruption of the first permanent molar was slightly higher in males than in females. The ectopic eruption of the first permanent molars is more common in the maxilla than in the mandible, and the incidence is roughly the same in the left and right maxilla. Bilateral first permanent molar eruption is more common than unilateral eruption.
