替牙期非龋源性乳牙根尖周脓肿临床分析

Clinical Analysis of Non-carious Periapical Abscesses of Deciduous Teeth in Mixed Dentition

目的:探讨替牙期非龋源性乳牙根尖周脓肿的发病原因及疗效评价。方法:对符合入选要求的37例经治患儿的42颗患牙进行松动度、龈沟完整度、患牙牙合接触的检查,并记录发病牙位;再把患儿随机分成3组,1组(开髓引流+药物)、2组(切开排脓+药物)以及3组(单纯药物)分别采取对应的治疗方案;观察治疗后1-3天的疗效。结果:替牙期冠部完整乳牙根尖周脓肿的发病原因与乳牙松动度及龈沟完整度高度相关,且多发于乳后牙,但与牙合接触无相关;乳牙根尖周脓肿的前期治疗方案中,"开髓引流+药物"和"切开排脓+药物"明显优于"单纯药物"治疗。结论:替牙期非龋源性乳牙根尖周脓肿的主要病因为乳牙松动度及龈沟完整度,前期治疗的最佳方案为开髓引流辅以全身抗菌治疗。

Objective： To explore the etiopathogenisis and efficacy evaluation of non-carious periapical abscesses of deciduous teeth in mixed dentition. Methods： Examining the tooth mobility, integrity of gingival crevieular, occlusal contact and tooth site of 42 restored teeth of 37 cases. The 37 children were randomly divided into 3 groups ： Group 1 （open pulp cavity and medicine）,group 2 （open abscess and medicine）,and group 3 （medicine only）. The efficacy was observed after treatment 1-3 days. Results： The morbidity was mostly associated with tooth mobility and integrity of gingival crevicular, but not occlusal contact. The primary molar suffered most time. Group 1 and 2 received better therapeutic efficacy than group 3. Conclusion： Tooth mobility and integrity of gingival crevicular might be the main cause of non-carious periapical abscesses of deciduous teeth in mixed dentition. In the prophase of treatment ,the open pulp cavity and medicine might be the best choice.
