The purpose of this study was to investigate the clinical variables influencing endodontic flare-ups. Three hundred and thirteen teeth receiving endodontic treatment at the Endodontic Department, Chang Gung Memorial Hospital were studied from December 1992 to February 1993. Among them, 21 teeth with significant pain and 9 with apical swelling were noted after the first appointment of treatment. Three teeth with persistent pain and one with apical swelling were also found one week after completion of endodontic therapy. The results showed significant improvement of clinical symptoms and signs one week after completion of endodontic treatment in comparison with pretreatment and after the first appointment (p < 0.025). The factors such as presence of pretreatment complaints, periapical lesions and vital pulp had significant effects on the incidence of endodontic flare-ups after the first appointment of treatment (P < 0.025). In contrast, patients' sex, the number of visits, and whether this was a retreatment case or not had no significant effect on the frequency of these endodontic flare-ups.
本研究的目的是调查影响牙髓病急性发作的临床变量。1992年12月至1993年2月，对长庚纪念医院牙髓病科接受牙髓治疗的313颗牙齿进行了研究。其中，首次治疗后有21颗牙齿出现明显疼痛，9颗牙齿出现根尖肿胀。在牙髓治疗完成一周后，还发现3颗牙齿持续疼痛，1颗牙齿出现根尖肿胀。结果显示，与治疗前和首次治疗后相比，牙髓治疗完成一周后临床症状和体征有显著改善（p < 0.025）。治疗前存在的主诉、根尖周病变和活髓等因素对首次治疗后牙髓病急性发作的发生率有显著影响（P < 0.025）。相比之下，患者的性别、就诊次数以及是否为再治疗病例对这些牙髓病急性发作的频率没有显著影响。
