Development of Screening melhod for oral walodor-Introducing to was oral health examinations-

本调查的目的是将口腔异味筛检系统引入口腔健康检查。采用便携式硫化物监测仪对2672名18 ~ 64岁的人（第一次调查）和201名35 ~ 60岁的人（第二次调查）进行口腔异味检测。此外，测量受刺激的唾液流速和唾液中的血红蛋白浓度，并评估牙周状况，包括探诊时出血、口袋探诊深度和附着丧失。临床检查前，对被试进行病史调查和口臭自我诊断。实际挥发性硫化合物（VSC）与自我诊断之间没有相关性。在男性和女性之间，以及不同年龄组之间，VSC值没有显著差异。唾液流量与VSC无相关性。舌苔与VSC有显著的相关性。唾液中的血红蛋白浓度和平均袋深等牙周参数不能反映口腔空气中VSC值的水平。然而，牙周袋深度为6mm或以上的部位的百分比与VSC之间存在显著相关性，附着体损失为6mm或以上的部位的百分比与VSC之间存在显著相关性。

The purpose of this survey was to introduce oral malodor screening system to the mas oral health examinations. Oral malodor was measured using a portable sulphide monitor in 2,672 people aged 18 to 64 years (1st survey) and in 201 persons aged 35 to 60 years (2nd survey). In addition, stimulated salivary flow rate and a hemoglobin concentration in saliva were measured, and periodontal conditions including bleeding on probing, pocket probing depths and loss of attachment were assessed. Before clinical examination, subjects were interviewed about their medical history and self-diagnosis of bad breath. No correlation was found between actual volatile sulphur compounds (VSC) and self-diagnosis. There were no significant differences observed in the VSC values between males and females, and among age groups. No correlation was found between salivary flow rate and VSC.There was a significant correlation observed between tongue coating and VSC.Periodontal parameters such as hemoglobin concentration in saliva and mean pocket depths could not reflect the level of VSC values in mouth air. However, significant correlations were found between the percentage of sites with periodontal pocket depth of 6 mm or more and VSC,and between the percentage of sites with attachment loss of 6 mm or more and VSC.
