摘要:
目的 研究非阻生第三磨牙对其邻牙健康状况的影响，对是否预防性拔除非阻生第三磨牙提供理论依据。方法 选择2017年1月~12月在十堰市太和医院医院口腔外科就诊并拍摄全景曲面断层片的858例患者为研究对象，分析其第三磨牙阻生与非阻生情况，及其对第二磨牙远中邻面龋、远中根吸收和牙槽骨吸收的影响。结果 第三磨牙缺失时，其相邻第二磨牙远中发生邻面龋、根吸收、牙槽骨吸收的患病率分别为4.55%、0.32%、10.31%；第三磨牙存在时，患病率分别为15.91%、2.39%、24.94%，其中第三磨牙非阻生状态时，患病率分别为5.22%、0.38%、13.84%。结论 第三磨牙的存在较第三磨牙缺失更易增加其邻牙发生病变风险。非阻生第三磨牙对相邻第二磨牙发生龋病和根吸收并无明显影响，但可显著增加相邻第二磨牙发生牙槽骨吸收风险，采取预防性拔除第三磨牙，可能会避免其对邻牙造成进一步损害。
Abstract:
Objective To study the effect of unimpacted third molar on the health of adjacent teeth and to provided a theoretical basis for whether to preventive extraction of the unimpacted third molar.Methods From January to December 2017, 858 patients who were admitted to the Department of Oral Surgery, Taihe Hospital, Shiyan city, and took panoramic radiography were selected as the study subjects.We made analysis of impaction and non-impaction of their third molars,and their effects on the distal surface caries, distal root resorption and alveolar bone resorption of the second molar.Results When the third molar was missing, the incidence of adjacent surface caries, root resorption and alveolar bone resorption were 4.55%,0.32% and 10.31% respectively.When the third molar was present, the prevalence rate was 15.91% and 2.39% and 24.94%, respectively.When the third molar was unimpacted, the prevalence rate was 5.22%,0.38% and 13.84%, respectively.Conclusion The presence of the third molar is more likely to increase the risk of lesions in the adjacent teeth than the loss of the third molar. Unimpacted third molar have no significant effect on caries and root resorption in adjacent second molars, but can significantly increase the risk of alveolar bone resorption in adjacent second molars. Prophylactic removal of third molars may avoid It causes further damage to adjacent teeth.
