Abstract

OBJECTIVE

To compare the effect of two newly formulated chlorhexidine (CHX) and cetylpyridinium chloride (CPC) mouthrinses after scaling and root planing (SRP) in terms of clinical, microbiological, patient-based variables and adverse events, with a positive control with the same active components, already marketed and tested.

METHODS

A pilot, randomized clinical trial, double-blind, parallel design with 1-month follow-up was conducted. Chronic periodontitis patients requiring non-surgical periodontal therapy were enrolled and randomly assigned to: (i) SRP and test-1 (new reformulation: 0.12% CHX and 0.05% CPC); (ii) SRP and test-2 (new formulation: 0.03% CHX and 0.05% CPC); or (iii) SRP and positive control (commercial product: 0.12% CHX and 0.05% CPC). All variables were evaluated at baseline and 1 month after SRP. Quantitative variables were compared by means of anova or Kruskal-Wallis test and qualitative variables by chi-square or McNemar tests.

RESULTS

Thirty patients (10 per group) were included. After 1 month, there were significant differences among groups in plaque levels (P = 0.016) as test-1 showed less sites with plaque than test-2 (31.15% [standard error-SE 2.21%] versus 49.39% [SE 4.60%), respectively). No significant differences were found for global patient perception of the product or in adverse effects. Test groups showed better results in levels and proportions (P = 0.022) of Capnocytophaga spp.

CONCLUSIONS

Within the limitations of this pilot study, it can be concluded that the newly formulated 0.12% CHX and 0.05% CPC mouthrinse showed larger plaque level reductions, without showing more adverse effects, when compared to the other two mouthrinses, after SRP.

摘要

目的

在接受牙周刮治和根面平整术(SRP)后,比较两种新配方的洗必泰(CHX)和氯化十六烷基吡啶(CPC)漱口液在临床、微生物学、基于患者的变量和不良事件方面的效果,与具有相同活性成分的阳性对照进行比较,该阳性对照已经上市并经过测试。

方法

进行了一项试点、随机、临床试验,采用双盲、平行设计,随访 1 个月。纳入需要非手术牙周治疗的慢性牙周炎患者,并随机分配到以下三组:(i)SRP 和测试 1(新配方:0.12%CHX 和 0.05%CPC);(ii)SRP 和测试 2(新配方:0.03%CHX 和 0.05%CPC);或(iii)SRP 和阳性对照(市售产品:0.12%CHX 和 0.05%CPC)。所有变量均在 SRP 前和 1 个月后进行评估。定量变量采用方差分析或 Kruskal-Wallis 检验进行比较,定性变量采用卡方检验或 McNemar 检验进行比较。

结果

共纳入 30 名患者(每组 10 名)。1 个月后,三组间菌斑水平有显著差异(P = 0.016),测试 1 组的菌斑少于测试 2 组(分别为 31.15%[标准误差-SE 2.21%]和 49.39%[SE 4.60%])。患者对产品的整体感知或不良事件无显著差异。测试组的 Capnocytophaga spp. 水平和比例(P = 0.022)改善更好。

结论

在本试点研究的限制范围内,可以得出结论,与其他两种漱口液相比,新配方的 0.12%CHX 和 0.05%CPC 漱口液在接受 SRP 后,显示出更大的菌斑水平降低,且没有显示出更多的不良反应。
