Post obturation pain is the pain of any degree after endodontic treatment. There are different opinions regarding incidence of post obturation pain related to single and multi visit root canal treatment. This prospective study was conducted to evaluate the incidence of post obturation pain in single visit and multi visit root canal treatment and to compare the incidence of pain between the two treatment groups. A total of 120 cases of endodontically involved asymptomatic non vital single rooted teeth were selected for this study. The patients were assigned and divided in to two treatment groups, sixty patients each. In single visit group, all teeth were prepared and filled using the standardized preparation and lateral condensation filling technique. In the multi visit treatment group, at the first appointment, the teeth were prepared, and dressed with calcium hydroxide paste for 7 days. At the second appointment, the teeth were prepared and obturated by using lateral condensation technique. The frequency of post obturation pain was recorded as no pain, slight, moderate and severe pain and evaluated at the day 1 and at the day 7 after obturation. The data were analyzed statistically by using SPSS version-12. P value <0.05 was taken as significant. The study showed that the post obturation pain in the single visit treatment group was more than multi visit treatment group, which is significant (p value <0.044). Out of the 120 patients, 86(71.7%) patients had no pain, 19(15.8%) had slight pain and 15(12.5%) patients had moderate pain at the day 1 after obturation. At the day 7 after obturation, 108(90%) patients had no pain, 9(7.5%) had slight pain and 3(2.5%) patients had moderate pain. No patient noticed severe pain during the follow up period. Older patient had significantly more post obturation pain than the younger patient. There was higher incidence of post obturation pain following the single visit root canal treatment. In multi visit root canal treatment with intra-canal medicaments seems to reduce the post obturation pain.
根管充填后疼痛是牙髓治疗后出现的任何程度的疼痛。关于单次就诊和多次就诊根管治疗相关的根管充填后疼痛发生率，存在不同观点。本前瞻性研究旨在评估单次就诊和多次就诊根管治疗中根管充填后疼痛的发生率，并比较两组治疗中疼痛的发生率。本研究共选取了120例牙髓受累的无症状非活髓单根牙病例。将患者分配并分为两个治疗组，每组60例。在单次就诊组中，所有牙齿均采用标准化预备和侧向加压充填技术进行预备和充填。在多次就诊治疗组中，首次就诊时，对牙齿进行预备，并用氢氧化钙糊剂封药7天。第二次就诊时，对牙齿进行预备并采用侧向加压技术进行充填。根管充填后疼痛的频率记录为无疼痛、轻微疼痛、中度疼痛和重度疼痛，并在充填后第1天和第7天进行评估。使用SPSS 12.0版对数据进行统计学分析。P值<0.05被视为具有统计学意义。研究表明，单次就诊治疗组的根管充填后疼痛多于多次就诊治疗组，差异具有统计学意义（P值<0.044）。在120例患者中，86例（71.7%）患者在充填后第1天无疼痛，19例（15.8%）有轻微疼痛，15例（12.5%）患者有中度疼痛。在充填后第7天，108例（90%）患者无疼痛，9例（7.5%）有轻微疼痛，3例（2.5%）患者有中度疼痛。在随访期间，没有患者出现重度疼痛。老年患者的根管充填后疼痛明显多于年轻患者。单次就诊根管治疗后根管充填后疼痛的发生率较高。在多次就诊根管治疗中使用根管内药物似乎可以减少根管充填后疼痛。
