Patients and Methods: A non-blind, cross-over, comparative, non-randomized, clinical trial was planned. The sample was composed of 32 patients requiring extraction under local anesthesia of two lower bony impacted mandibular third molars. The difficulty of extraction was similar in all cases. The patients received 20 mg of methylprednisolone injected into the masseter muscle via the intrabuccal approach, immediately after suturing of the surgical wound on the right side. The left side received no intramuscular corticoid. Evaluations were made of postoperative pain and swelling. Results: A total of 32 subjects requiring surgical removal of two impacted mandibular third molars under local anesthesia were included in the present study. The patients administered methylprednisolone showed superior results after surgery in terms of pain and facial swelling parameters using self-evaluation, with statistically significant differences versus the control-side (p < 0.05). The results obtained show that 20 mg of methylprednisolone injected into the masseter muscle in the immediate postoperative period reduces swelling and pain. Conclusions: Injection of methylprednisolone is an effective therapeutic strategy to reduce swelling and pain after surgical removal of impacted lower third molars. It offers a simple, safe, painless, noninvasive, and cost effective therapeutic option for moderate and severe cases.展开更多
目的比较采用赤藓糖醇喷砂法和矽粒子旋转抛光法治疗儿童外源性牙面黑色素沉着(extrinsic black tooth stain,EBS)的临床疗效。方法筛选符合纳入标准的3~12岁儿童48名,通过改良Lobene色斑指数记录色素水平,采用自身半口对照,随机将左右...目的比较采用赤藓糖醇喷砂法和矽粒子旋转抛光法治疗儿童外源性牙面黑色素沉着(extrinsic black tooth stain,EBS)的临床疗效。方法筛选符合纳入标准的3~12岁儿童48名,通过改良Lobene色斑指数记录色素水平,采用自身半口对照,随机将左右侧分为试验组和对照组,试验组用赤藓糖醇喷砂法,对照组用矽粒子旋转抛光法清除牙齿唇颊面EBS,记录操作时间,进行治疗感受评分,评价治疗安全性,采用“色素积分(score)除以操作时间(second)”计算清洁效率(S/s),随访治疗后3个月和6个月色素再附着水平,通过SPSS23.0软件分析试验结果。结果治疗前唇颊面左右两侧色素得分差异无统计学意义,舌腭面色素得分大于唇颊面,牙面不同分区的色素得分有统计学差异。试验组的效率高于对照组[(0.06±0.05)S/s vs(0.04±0.02)S/s,P<0.001]。8例(16.7%)研究对象对喷砂治疗感到紧张,7例(14.6%)研究对象喷砂治疗过程中出现牙龈出血。治疗前、治疗后3个月、6个月试验组和对照组色素水平差异无统计学意义(P>0.05)。结论虽然赤藓糖醇喷砂更容易导致牙龈出血,使儿童紧张,但其清除色素效率更高,值得临床推广。展开更多
