The objective of this study was to compare postobturation flare-ups following single and two-visit endodontic treatment of molar teeth with periapical radiolucency.
A total of 100 patients with asymptomatic molar teeth with periapical radiolucency were selected. They were randomly allocated into two groups. Fifty patients received complete endodontic treatment in one-visit. Fifty patients received treatment by debridement and instrumentation at the first visit followed by obturation at the second visit.
10% of patients had flare-ups in the single visit group and 8% of patients had flare-ups in the two-visit group. Number of visits did not affect the success of endodontic treatment (p>0.05). Age, gender and tooth type had no effects on the occurrence of flare-ups regardless the number of visits (p>0.05).
One-visit endodontic treatment was as successful as two-visit endodontic treatment as evaluated by rate of flareups in asymptomatic molar teeth with periapical radiolucency.
本研究的目的是比较对有根尖周透射区的磨牙进行单次和两次就诊的根管治疗后根管充填后疼痛发作情况。
共选择100例有根尖周透射区的无症状磨牙患者。他们被随机分为两组。50例患者接受一次性完成根管治疗。50例患者在第一次就诊时进行清创和根管预备，第二次就诊时进行根管充填。
单次就诊组10%的患者出现疼痛发作，两次就诊组8%的患者出现疼痛发作。就诊次数不影响根管治疗的成功率（p＞0.05）。无论就诊次数如何，年龄、性别和牙位对疼痛发作的发生均无影响（p＞0.05）。
以有根尖周透射区的无症状磨牙疼痛发作率评估，一次性根管治疗与两次就诊的根管治疗同样成功。
