In this randomized clinical trial, 64 patients who had mandibular first and second molars with irreversible pulpitis were randomly divided into two groups ( = 32) by stratified permuted block randomization. The experimental group used 60 mg KTP every 6 hours, and the control group received 400 mg ibuprofen tablets every 6 hours for 1 day. The severity of pain experienced by patients was quantified before and at 2, 4, 8, 12, 24, and 48 hours after endodontic treatment, using the numerical rating scale (NRS). Data were analyzed by using the -test, Mann-Whitney test, and generalized estimating equation (GEE) (alpha = 0.05).
The pain score was not significantly different between the two groups at the baseline or any other postoperative time point ( > 0.05). The reduction in the pain score was significant in both groups from 2 to 10 hours and 10 to 48 hours, postoperatively ( < 0.001). The interaction effect of time and group was not significant on the postoperative pain score in the abovementioned time intervals, and the pattern of pain reduction was the same over time in both groups ( > 0.05).
Both KTP and ibuprofen effectively decreased postendodontic pain. Considering the comparable pattern of pain reduction, KTP can be used as an alternative to ibuprofen tablets for effective pain control after endodontic treatment of mandibular first and second molars with irreversible pulpitis.
在这项随机临床试验中,64 名患有不可复性牙髓炎的下颌第一、二磨牙患者,采用分层区组随机化分组法分为两组(n=32)。实验组每 6 小时使用 60mg KTP,对照组每 6 小时使用 400mg 布洛芬片,治疗持续 1 天。采用数字评分量表(NRS)在牙髓治疗前和治疗后 2、4、8、12、24 和 48 小时分别量化患者的疼痛程度。采用 t 检验、Mann-Whitney 检验和广义估计方程(GEE)(α=0.05)进行数据分析。
两组患者在基线或任何其他术后时间点的疼痛评分均无显著差异(>0.05)。两组患者的疼痛评分均从术后 2 小时至 10 小时和 10 小时至 48 小时显著降低(<0.001)。在上述时间间隔内,时间和组之间的交互效应对术后疼痛评分没有显著影响,两组的疼痛缓解模式随时间变化相同(>0.05)。
KTP 和布洛芬均可有效减轻牙髓治疗后的疼痛。考虑到疼痛缓解的模式相似,KTP 可作为布洛芬片的替代药物,用于治疗不可复性牙髓炎的下颌第一、二磨牙的牙髓治疗后有效控制疼痛。
