The purpose of this study was to examine the relationship between turbidity of mouth rinsed water and oral health status such as dental and periodontal conditions, oral hygiene status, flow rate of saliva and oral bacteria.
Subjects were 165 patients who visited the Dental Hospital, Tokyo Medical and Dental University. Oral health status, including dental and periodontal conditions, oral hygiene status and flow rate of saliva, was clinically examined. The turbidity was measured with a turbidimeter. Quantification of Fusobacterium spp, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and total bacteria levels was performed using real-time PCR. The Pearson correlation and multiple regression analysis were used to explore the associations between the turbidity and oral health parameters.
The turbidity showed significant correlations with the number of decayed teeth and deep pockets, the plaque index, extent of tongue coating and Fusobacterium spp, P. gingivalis, T. forsythia, T. denticola and total bacteria levels. In a multiple regression model, the turbidity was negatively associated with the flow rate of saliva and positively associated with the total number of bacteria (p < 0.001).
Current findings suggested that turbidity of mouth rinsed water could be used as an indicator to evaluate oral health condition and the amount of bacteria in the oral cavity. In addition, the turbiditimeter appeared as a simple and objective device for screening abnormality of oral health condition at chair side as well as community-based research.
本研究旨在探讨漱口水中的浑浊度与口腔健康状况（如牙齿和牙周状况、口腔卫生状况、唾液流速和口腔细菌）之间的关系。
研究对象为 165 名就诊于东京医科齿科大学口腔医院的患者。临床检查口腔健康状况，包括牙齿和牙周状况、口腔卫生状况和唾液流速。采用浊度计测量浑浊度。使用实时 PCR 定量检测 Fusobacterium spp、Porphyromonas gingivalis、Tannerella forsythia、Treponema denticola 和总细菌水平。采用 Pearson 相关分析和多元回归分析探讨浑浊度与口腔健康参数之间的关系。
浑浊度与龋齿数和深牙周袋数、菌斑指数、舌苔程度以及 Fusobacterium spp、P. gingivalis、T. forsythia、T. denticola 和总细菌水平呈显著相关。在多元回归模型中，浑浊度与唾液流速呈负相关，与总细菌数呈正相关（p<0.001）。
目前的研究结果表明，漱口水中的浑浊度可以作为评估口腔健康状况和口腔内细菌数量的指标。此外，浊度计作为一种简单、客观的设备，可以在椅旁和社区研究中筛查口腔健康异常情况。
