Bad breath Semiconductor sensor Hydrogen Volatility sulfur compounds

项目摘要

In the fixed quantity of bad breath, it is a worldwide standard to make VSC(Volatility sulfur compounds) an index. However, there is an example that is not detected VSC even if stinking in the sensory inspection. and this is a problem of the bad breath science. Then, it was not all densities that were able to be detected though the stink elements other than VSC were analyzed by the gas chromatography.Might it be guessed that hydrogen is generated with the stink in the reluctance fermentation in the enteric canal, too, and measuring this hydrogen become the index of the stink.This is a reason why it starts the research that we measure hydrogen from the mouth air.The device that detected the hydrogen contained in the gas of the mouth with a semiconductor sensor with uniqueness to hydrogen was developed.The concentration of hydrogen in a human mouth was 1 to 200ppm, and the detection sensitivity endured practical use. The resident's agreement was obtained and hydrogen and VSC were measured. Moreover, the relation to the question paper investigation of the digestive organs symptom was examined.Results1)The concentration of hydrogen that had been obtained from intraoral gas was 2.4ppm in average.2)A plain correlation was not admitted between hydrogen and the VSC concentration.3)The tendency with high concentration of hydrogen of the person who appealed for the slump to a digestive tube was shown.4)The correlation was seen between periodontitis and the concentration of hydrogen.5)There is a possibility that hydrogen can be used as indices of the bad breath in the mouth other than VSC that could not be measured so far.ConclusionBad breath and digestive organs have some relations.There are some relations up to the concentration of hydrogen and the periodontal pocket in the mouth, and it becomes the starting point of a new research.

在固定数量的口臭中，将VSC（波动性硫化合物）变为索引是全球标准。但是，即使在感觉检查中臭味，也没有检测到的示例。这是口臭科学的问题。然后，并非所有的密度都能被检测到，尽管通过气体色谱对VSC以外的其他臭元素进行了分析。可能会猜测，氢在肠道内的不情愿发酵中也会产生氢，也可以测量该液体的氢气。我们的氢气始终是氢的。开发了具有半导体传感器的口腔，对氢的独特性开发了。人口中的氢浓度为1至200ppm，检测灵敏度持续了实际用途。获得了居民的一致性，并测量了氢和VSC。此外，检查了与问题论文对消化器官症状的研究的关系。回报1）从口内气体获得的氢的浓度平均为2.4ppm。2）氢气与vsc浓度之间的氢气浓度不高。牙周炎和氢的浓度。5）有可能将氢用作口腔中口臭的指标以外的VSC以外的其他无法测量的氢。ConclusionBad呼吸和消化器官有一定的关系。有一些关系，直到氢气和口腔中的牙周口袋的浓度，这就是一项新的研究点。
