摘要/Abstract

摘要： 目的： 通过锥形束CT（cone-beam CT, CBCT）分析儿童及青少年下颌骨骨折患者牙损伤（dental injuries, DIs）的发生情况及类型,探讨DIs与下颌骨骨折的相关性。方法： 回顾2021年1月—2023年12月河北医科大学第三医院收治的81例下颌骨骨折患者的病例资料,根据CBCT图像获取下颌骨骨折类型、DIs类型及牙位等,分析下颌骨骨折类型与DIs的关系。采用SPSS 26.0软件包对数据进行统计学分析。结果： 81例患者中,63例（77.78%）出现DIs,男女比例为2∶1。共有231颗牙损伤（247例DIs）,乳牙与年轻恒牙最常见DIs类型为部分脱位（29.17%,40.00%）,恒牙最常见DIs类型为牙冠折（39.60%）。上颌前牙为最常见的损伤牙位,骨折类型与DIs发生牙位之间的差异具有统计学意义（P=0.047）。乳牙多发生涉及软组织的损伤（83.30%）,牙发育类型与涉及软硬组织的DIs类型的差异具有统计学意义（P<0.001）。年轻恒牙多发生轻度损伤（88.00%）,牙发育类型与发生DIs严重程度的差异具有统计学意义（P=0.001）。结论： 通过CBCT能够对下颌骨骨折及DIs进行全面诊断,DIs的发生和类型与下颌骨骨折密切相关。

Abstract: PURPOSE: To analyze the occurrence and type of dental injuries(DIs) in children and adolescents with mandibular fracture by cone-beam computed tomography(CBCT), and to explore the correlation between DIs and mandibular fracture. METHODS: The data of 81 patients with mandibular fracture admitted to the Third Hospital of Hebei Medical University from January 2021 to December 2023 were reviewed, the mandibular fracture type, DIs type and dental position were obtained according to CBCT images, and the relationship between mandibular fracture type and DIs was analyzed. SPSS 26.0 software package was used for statistical analysis. RESULTS: DIs occurred in 63 patients(77.78%), with a male/female ratio of 2:1. A total of 247 DIs occurred in 231 teeth, the most common type of DIs was extrusive luxation in primary teeth(29.17%) and immature permanent teeth(40.00%), and crown fracture(39.60%) in permanent teeth. Maxillary anterior teeth were the most common damaged tooth sites, and the difference between fracture types and DIs sites was statistically significant (P=0.047). The lesions involving soft tissue were more common in primary teeth (83.30%), and the difference between tooth development type and DIs type involving soft and hard tissue was statistically significant(P<0.001). There were more mild injuries in immature permanent teeth(88.00%). The difference between the type of tooth development and the severity of DIs was statistically significant(P=0.001). CONCLUSIONS: CBCT can be used for comprehensive diagnosis of mandibular fracture and DIs. The occurrence and type of DIs are closely related to mandibular fracture.
