This study evaluated the effect of a calculus scaling gel (SofScale) on time and ease of the scaling procedure in a double-blind, split-mouth clinical study of 32 subjects. The Volpe-Manhold calculus index was used to quantify the distribution and amount of calculus deposition on the lingual aspect of the mandibular 6 anterior teeth at baseline. The gel was applied directly to the calculus and subgingivally to the area to be scaled. Pre- and post-treatment gingival and stain indices were taken. Operator and subject questionnaires were completed immediately after treatment to determine ease of the scaling procedure. Results were analyzed with paired t-tests. The time difference in scaling between the product and placebo side was not significant. This study found that SofScale is safe to gingival tissues and does not promote tooth sensitivity. However, this study did not find significant differences in scaling time between product and placebo when using a 2-minute gel contact time.
本研究在一项针对32名受试者的双盲、半口对照临床研究中,评估了一种牙石刮治凝胶(SofScale)对刮治过程的时间和难易程度的影响。在基线时,使用Volpe-Manhold牙石指数来量化下颌6颗前牙舌侧牙石沉积的分布和数量。将凝胶直接涂抹在牙石上,并在龈下涂抹到要刮治的区域。记录治疗前后的牙龈指数和色斑指数。治疗后立即完成操作者和受试者问卷,以确定刮治过程的难易程度。结果采用配对t检验进行分析。产品侧和安慰剂侧的刮治时间差异不显著。本研究发现,SofScale对牙龈组织是安全的,不会引起牙齿敏感。然而,当凝胶接触时间为2分钟时,本研究未发现产品与安慰剂在刮治时间上有显著差异。
