In recent years, three multicenter studies have been conducted to evaluate the clinical efficacy of an active 5% dental gel to reduce pain when placed into periodontal pockets before initiating scaling and root planing procedures. In each of the clinical studies, the researchers found statistically significant differences between the pain scores of the active dental gel group and the placebo gel group that favored the active gel for the control of pain during periodontal scaling and root planing procedures. This article reviews each of the three studies and highlights some of the differences among them.
近年来，已经开展了三项多中心研究，以评估一种活性5%牙科凝胶在进行龈下刮治和根面平整手术前放入牙周袋时减轻疼痛的临床疗效。在每项临床研究中，研究人员发现活性牙科凝胶组和安慰剂凝胶组的疼痛评分之间存在统计学上的显著差异，这表明在牙周刮治和根面平整手术期间，活性凝胶在控制疼痛方面更具优势。本文回顾了这三项研究，并强调了它们之间的一些差异。
