问题陈述
适当的菌斑控制对于维持健康的口腔粘膜是必不可少的。义齿清洁剂是假牙佩戴者常用的清洁方法。一种新的片状清洁剂的临床效果尚未在体内进行测试。用于在体评估义齿清洁剂效果的方法往往没有标准化。
目的
这项活体研究的目的是开发一种新的方法，通过使用数字成像来评估义齿上的菌斑水平，并使用该方法和经过验证的视觉评分方法来评估义齿上的菌斑积聚。
材料和方法
35名受试者被随机分为两组：(1)用新清洁剂浸泡义齿，或(2)用水浸泡义齿。疗程为14天。在基线、第2天和第14天通过数字图像分析和视觉评分技术评估斑块。结果采用方差分析，可信区间为95%。
结果
与水相比，新清洁剂在第2天的平均视觉斑块减少了51%(P=0.0002)，在第14天的平均视觉斑块减少了42%(P=0.0014)。在数字成像中也看到了类似的结果。
结论
这种新型义齿清洁剂被证明能有效地防止义齿上的菌斑堆积。对数字图像的分析得出了与视觉计分方法类似的结果。
STATEMENT OF PROBLEM
Adequate plaque control is essential for the maintenance of a healthy oral mucosa. Denture cleansers are a popular method used by denture wearers for cleaning. The clinical effectiveness of a new cleanser in tablet form has not been tested in vivo. Methods used for the in vivo assessment of denture cleanser effectiveness are often not standardized.
PURPOSE
The aims of this in vivo study were to develop a new method for assessing plaque levels on dentures by using digital imaging and to use this methodology, together with a validated visual scoring method, to evaluate plaque buildup on dentures.
MATERIAL AND METHODS
Thirty-five subjects were randomized to 1 of 2 treatment groups: (1) dentures soaked in a new cleanser, or (2) dentures soaked in water. The treatment period lasted 14 days. Plaque was assessed at baseline and on days 2 and 14 by using digital image analysis and a visual scoring technique. Results were analyzed with ANOVA at the 95% confidence interval.
RESULTS
The new cleanser showed a statistically significant reduction in mean visual plaque of 51% at day 2 (P = 0.0002) and 42% (P = 0.0014) at day 14 compared with water. Similar results were seen with digital imaging.
CONCLUSION
The new denture cleanser proved to be effective at preventing plaque accumulation on dentures. The analysis of digital images gave similar results as the visual scoring method.
