摘要： 目的: 探讨2019年1~12月吉林省口腔疾病患者中牙内陷患病率和影像表现,为临床制定治疗方案提供基础。方法: 选取2019年1~12月吉林大学口腔医院共3038例患者CBCT资料。观察到患牙类牙釉质密度影像由冠方向根方凹陷或可形成根管样结构时,记录患牙牙位,内陷程度及患者的性别。结果: 在符合条件的3038例患者影像资料中共发现90例牙内陷患者,牙内陷在人群中的发病率约为3.00%。双侧牙内陷病例48例,单侧牙内陷病例42例。检测样本中总牙数67543颗,其中牙内陷患牙共139颗,可知牙患病率约为0.21%。根据Oehler’s牙内陷分类法分组,发现OehlersⅠ型牙内陷患牙数最高,约占总患牙数的71.94%。上颌侧切牙发生牙内陷最多,约占87.05%。根据牙位分析可知牙内陷患牙多集中于上颌前牙区。通过秩和检验和χ2检验可得牙内陷的发生以及严重程度与性别无明显相关。结论: 牙内陷并没有以往认为的那样罕见,应引起临床医生的重视,适当采用新技术治疗。

Abstract: Objective: To explore the prevalence of dens invaginatus and imaging features in a sample of dental patients in Jilin province from January 2019 to December 2019. Methods: The data was collected from examination of 3038 CBCT radiographs. When the enamel image of the tooth was observed to be sunken from crown to the root or to form a root canal-like structure, the position of the affected tooth, the degree of invagination, and the gender of the patient were recorded. Results: Teeth with dens invaginatus were found in 90 subjects out of 3038 subjects. The person prevalence was about 3.00%. Bilateral dens invaginatus was seen in 48 patients, whereas unilateral dens invaginatus was demostrated in 42 patients. Den invaginatus was detected in 139 teeth out of 67543 teeth with a tooth prevalence of 0.21%. According to Oehler’s classification of dens invaginatus, Oehlers type I was the highest percentage of teeth with dens invaginatus, accounting for about 71.94% in the affected teeth. Maxillary lateral incisors were the most common teeth affected with the dens invaginatus, accounting for about 87.05%. The teeth with dens invaginatus were mostly concentrated in the maxillary anterior region. The prevalence and Oehler’s classification of teeth with dens invaginatus was not significantly related to gender. Conclusion: Dens invaginatus are not as rare as previously thought, and should be paid attention to by dentists, and new techniques should be used for treatment.
