Visually impaired patients are unable to visualize the plaque on tooth surfaces resulting in inadequate plaque removal and therefore the progression of dental caries and inflammatory disease of the periodontium. The objective of the study was to assess the effectiveness of herbal mouth wash in reduction of plaque and gingivitis among visually impaired children.
Randomized controlled clinical trial was conducted with parallel groups study, comprising 6 to 20 year old visually impaired children, 20 in each group (herbal mouth wash or chlorhexidine mouthwash or placebo mouthwash). Plaque and gingival index were recorded at baseline and at the end of the study. Children were asked to use the mouth wash twice daily for two weeks. Analysis was done using Chi-square test for categorical data and Mann-Whitney U test/independent t-test and one way analysis of variance/Kruskal-wallis H test for quantitative data. The level of significance was set at P<0.05.
Participants showed fair oral hygiene (mean plaque scores of 1.14±0.53) and moderate gingivitis (mean gingival scores of 1.12±0.45) with no significant difference between three groups (P=0.47 and 0.84, respectively). Significant reduction of plaque and gingivitis was seen at follow-up with no significant difference between herbal and chlorhexidine mouthwash. However, significant difference was found between placebo and herbal/chlorhexidine mouthwash.
Herbal mouthwash showed significant effect on reducing plaque formation and gingivitis in visually impaired students. The effectiveness of herbal mouthwash was analogous to the gold standard chlorhexidine.
视力受损患者无法看到牙齿表面的牙菌斑,导致牙菌斑清除不充分,进而引发龋齿和牙周炎。本研究的目的是评估草药漱口水在减少视力受损儿童牙菌斑和牙龈炎方面的效果。
采用平行组随机对照临床试验,研究对象为6至20岁的视力受损儿童,每组20人(草药漱口水组、洗必泰漱口水组或安慰剂漱口水组)。在基线和研究结束时记录牙菌斑和牙龈指数。要求儿童每天使用漱口水两次,持续两周。分类数据采用卡方检验分析,定量数据采用曼-惠特尼U检验/独立t检验以及单因素方差分析/克鲁斯卡尔-沃利斯H检验。显著性水平设定为P<0.05。
参与者口腔卫生状况一般(平均牙菌斑评分为1.14±0.53),牙龈炎程度中等(平均牙龈评分为1.12±0.45),三组之间无显著差异(分别为P=0.47和0.84)。随访时牙菌斑和牙龈炎显著减少,草药漱口水和洗必泰漱口水之间无显著差异。然而,安慰剂漱口水与草药漱口水/洗必泰漱口水之间存在显著差异。
草药漱口水对减少视力受损学生的牙菌斑形成和牙龈炎有显著效果。草药漱口水的效果与金标准洗必泰类似。
