根管治疗期间急症相关因素的临床研究

Correlative factors of endodontic interappointment emergencies:a clinical research

目的对根管治疗期间急症（IAE）的相关因素进行临床评价。方法对3801例患者（共4062颗惠牙）进行临床评价，对性别、年龄、系统性疾病、过敏体质、患牙解剖位置、牙髓状况、治疗前症状、有无瘘道和根尖阴影以及封药药物等因素进行分析。结果IAE发生率女性多于男性，40～60岁发生率最高，而小于20岁者发生率最低，在有系统疾病、过敏体质者中的发生率多于无系统疾病、无过敏体质者，下颌牙发生率多于上颌牙，磨牙多于前磨牙、前牙，在牙髓无活力、治疗前有症状、根尖无阴影者中的发生率多于牙髓有活力、治疗前无症状、根尖有阴影者，封入樟脑酚者发生率最低，其差异均有统计学意义（P〈0．05）；而甲醛甲酚与氢氧化钙比较差异无统计学意义（P〉0．05）。结论IAE的发生与患者体质、患牙解剖位置、患牙病情和封药药物有关。临床操作中应予以重视。

Objective To evaluate the correlative factors of endodontic interappointment emergencies（IAE） by clinical observa- tion. Methods Evaluated the factors of 3 801 patients（4 062 teeth） ,including distinction,age, systematic disease, allergic constitu- tion,tooth location, pulp status, pretreatment pain, fistula, periapical radiolucency and medicaments. Results The occurrences of IAE under these factors had significant defferences（P〈0.05） and the following were the typical ones. Female〉male;40-year-old to 60-year-old had the highest occurrences and the under-20 year-old had the lowest;patients who had systematic diseases and allergic constitution had higher occurrences ; mandibula〉maxillary ; molar teeth〉 premolar teeth〉 anterior teeth ; novital puip〉 vital pulp ; patients who had pretreatment pain had higher occurrences;presence of periapical radiolueency〉absense of periapical radiolucency; CP had the lowest occurrences. Nevertheless, the occurrences of FC and calcium hydroxide had no statistical signifieance（P〉0.05）. Conclusion The occurrences of IAE have correlations with patients＇ constitutions,teeth location, teeth status and medicaments. While RCT operating,they should be highly respected.
