To evaluate the incidence of flare-ups and identify the risk factors including age, gender, tooth type, number of root canals, initial diagnosis, the type of irrigation regimen, treatment modality and the number of visits, in patients who received root canal treatment from January 2002 to January 2008.
Records of 1819 teeth belonging to 1410 patients treated by 1 endodontics specialist during 6-year period were kept. Patient, tooth, and treatment characteristics were evaluated and the relationships between these characteristics and flare-ups were studied. Statistical analysis was carried out by using Pearson Chi-square test, Fisher's Exact test, and Binary Logistic regression analyses.
The incidence of flare-ups was 59 (3.2 %) out of 1819 teeth that received endodontic therapy. Pulpal necrosis without periapical pathosis was the most common indication for flare-up (6 %) (p < 0.01). Teeth undergoing multiple visits had a higher risk of developing flare-ups compared to those with single appointments (OR: 3.14, CI: 1.414-7.009, p < 0.01). There were also no statistically significant differences in the incidence of flare-ups regarding to age, gender, tooth type, number of root canals, treatment modality, and the irrigation solutions that used during the treatment.
The incidence of flare-up is minimal when teeth are treated in one visit. Absence of a periapical lesion in necrotic teeth is a significant risk factor for flare-ups.
评估2002年1月至2008年1月期间接受根管治疗的患者中病情突然加重的发生率,并确定包括年龄、性别、牙齿类型、根管数量、初始诊断、冲洗方案类型、治疗方式和就诊次数在内的风险因素。
保存了1名牙髓病专科医生在6年期间治疗的1410例患者的1819颗牙齿的记录。对患者、牙齿和治疗特征进行了评估,并研究了这些特征与病情突然加重之间的关系。采用Pearson卡方检验、Fisher精确检验和二元逻辑回归分析进行统计分析。
在接受牙髓治疗的1819颗牙齿中,病情突然加重的发生率为59例(3.2%)。无根尖周病变的牙髓坏死是病情突然加重最常见的指征(6%)(p<0.01)。与单次就诊的牙齿相比,多次就诊的牙齿发生病情突然加重的风险更高(比值比:3.14,置信区间:1.414 - 7.009,p<0.01)。在病情突然加重的发生率方面,年龄、性别、牙齿类型、根管数量、治疗方式以及治疗期间使用的冲洗液之间也没有统计学上的显著差异。
一次就诊治疗牙齿时病情突然加重的发生率极低。坏死牙齿中无根尖周病变是病情突然加重的一个重要风险因素。
