Description

【0001】
【発明の属する技術分野】
本発明は、ウ蝕,歯周病,口内炎,カンジダ感染症等およびこれらに伴う口臭の有無を簡便に判定できる唾液性状検査用キット、および口腔内疾患の有無を判定する方法に関するものである。
【0002】
【従来の技術】
近年、食生活等の生活習慣の変化や高齢化の進行に伴って、ウ蝕,歯周病,口内炎,カンジダ感染症などの感染症およびこれらに伴う口臭等の口腔内トラブルに関する問題がますます増加してきている。
【0003】
これらは医師の診断や検査等によって、その種類や進行程度を知ることができるが、疾患が自覚症状として顕れていない場合や疾患を原因の一つとすることの意識が低い口臭判定では、専門家の補助無く簡便に行なえる評価が好ましい。
【0004】
ところで、本来唾液は無臭であるのみならず、ウ蝕を進行させる口腔内pHの低下を軽減する緩衝作用を有し、細菌や真菌の感染を予防および軽減するリゾチーム,ラクトフェリン,免疫グロブリンであるIgA等を含み、また、口腔内の雑菌や有臭物質等を洗浄する作用も有している。従って、唾液分泌量が口腔内疾患や口臭の有無の指標となるとの考えから、唾液量やその粘度を測定して口腔内の状態を判断する技術が開発されている。
【0005】
例えば、特許文献1には、唾液の量や粘性を判定することができる唾液検査用具が記載されている。当該用具は浸透性を有する支持体からなり、唾液量やその浸透度,浸透速度,および粘度を簡便に判定することができる。
【0006】
しかし、この様な用具では唾液量等を測定できるのみであり、直接的に口腔内疾患や口臭の有無を判定できるわけではない。
【0007】

【0008】
【発明が解決しようとする課題】
上述した様な状況のもと、本発明の解決課題は、口腔内疾患およびそれに伴う口臭の有無を従来の簡便な方法より高い精度で判定することができ、且つ専門家の補助が無い場合であっても簡便かつ簡易に実施することができる技術を提供することにある。
【0009】
【課題を解決するための手段】
本発明者らは、上記課題を解決すべく鋭意研究を行なったところ、口腔内疾患の進行、即ちウ蝕や歯周病等の原因菌の増殖に伴って、その代謝による不溶性物質が増加するという新たな知見のもと、唾液中に含まれる不溶性物質の量を測定すれば口腔内疾患やそれに伴う口臭の有無の目安になることを見出して、本発明を完成するに至った。
【0010】
即ち、本発明に係る唾液性状検査用キットは、一定量の唾液を装入する透明容器、該唾液中に含まれる不溶性物質の量を測定する手段、および該不溶性物質量により唾液性状を評価する手段を有することを特徴とする。
【0011】
また、唾液中に含まれる不溶性物質の量と唾液の濁度には相互関係があることから、本発明の唾液性状検査用キットは、唾液を装入する透明容器、該唾液の濁度を測定する手段、および該濁度により唾液性状を評価する手段を有するものであってもよい。
【0012】
更に、本発明の唾液性状検査用キットは、唾液中に含まれる不溶性物質の量と濁度の両方を測定することができるもの、つまり、一定量の唾液を装入する透明容器、該唾液中に含まれる不溶性物質の量を測定する手段、該唾液の濁度を測定する手段、並びに該不溶性物質量および該濁度により唾液性状を評価する手段を有するものであってもよい。
【0013】
上記唾液性状検査用キットは、唾液の色調を測定する手段を備えることによって、更に多面的な口腔内疾患等の判定が可能となる。
【0014】
また、本発明に係る口腔内疾患判定方法は、一定量の採取唾液中に含まれる不溶性物質量により口腔内疾患の有無を判定し、或いは、採取唾液の濁度により口腔内疾患の有無を判定することを特徴とする。
【0015】
【発明の実施の形態】
本発明に係る唾液性状検査用キットと口腔内疾患判定方法が享有する最大の特長は、唾液に含まれる不溶性物質の量またはその濁度を測定するという極めて簡便な作業のみで口腔内疾患や口臭の有無を判断できる点にある。即ち、これまでにも唾液のpHや緩衝能、唾液中の口腔内疾患原因菌の存在を測定することによってウ蝕の有無や口腔内環境を簡便に判断する技術はあったが、本発明は、唾液に含まれる不溶性物質の量または唾液の濁度と口腔内疾患の進行度には密接な関係があるとの新しい知見のもと、簡便に且つより高い精度で口腔内疾患等の有無の判断を可能としたものである。
【0016】
以下に、斯かる特徴を発揮する本発明の実施形態、及びその効果について説明する。
【0017】
本発明に係る第1の唾液性状検査用キットは、一定量の唾液を装入する透明容器、該唾液中に含まれる不溶性物質の量を測定する手段、および該不溶性物質量により唾液性状を評価する手段を有している。
【0018】
「一定量の唾液を装入する透明容器」は、一定量の唾液を装入することができるものであり、且つ採取した唾液の性状を外部から観察できる透明のものであればよい。また、その容量は、数分で採取できる唾液の一般的な量に対応させ5ml程度以下であれば十分であり、採取唾液量を示す目盛りが付されているものであってもよく、濁度を測定するための記号等が底面或いは側面に設けられていてもよく、更に、より細長い形状のものであれば不溶性物質の沈殿率等を測定し易いが、本発明の範囲はこれらに拘束されない。但し、内径が過剰に大きいものであると不溶性物質を定量し難い場合があるので、その内径は1cm程度以下であることが好ましい。その様な「一定量の唾液を装入する透明容器」としては、例えば小型の試験管やテストチューブ等を挙げることができる。
【0019】
唾液の採取は、上部が唾液を採取し易い形状(例えば、ロート状等)にされた「一定量の唾液を装入する透明容器」に直接行なってもよいが、別容器に採取した後に一定量を量り採り「一定量の唾液を装入する透明容器」に装入すれば採取が容易であることから、複数サンプルを比較する際に便利である。
【0020】
「唾液」には、特別な刺激がなくても絶えず分泌される安静時唾液と、咀嚼等の刺激によって分泌される刺激唾液があるが、本発明では何れも使用できる。但し、複数の被験者を検査する場合には、安静時唾液であるか又は刺激唾液であるかを統一することが望ましい。唾液性状がその種類により異なる場合があるからである。また、一般的には、採取量の面から刺激唾液が使用し易い。更に、唾液性状等は食事の影響を受け易いため、食後から一定時間後の唾液等、採取時間を定めておくことが好ましい。
【0021】
「唾液中に含まれる不溶性物質の量を測定する手段」は、一定量の唾液中に含まれる不溶性物質の量を客観的に測定できるものであれば特に制限されず、例えば、採取唾液を濾過した後に不溶性物質量を測定するものであってもよい。しかし、濾過後では後述する「濁度」を測定することができないことや、より簡便に当該量を測定するために、本発明では沈殿率として測定することが好ましい。この「沈殿率」の測定は必ずしも厳密なものである必要はなく、例えば、一定量の採取唾液を一定時間静置し、全体唾液量(「透明容器」中での唾液高さであってもよい)に対する沈殿した部分の量(同様に、「透明容器」中での沈殿分高さであってもよい)の割合として算出したものでもよい。沈殿を促進するために遠心分離機等を使用してもよいが、評価を簡易簡便とするためには静置することが好ましい。
【0022】
口腔内疾患の種類は特定できないまでも、「唾液中に含まれる不溶性物質の量を測定する手段」により測定された不溶性物質量を、客観的にウ蝕等の口腔内疾患やそれに伴う口臭の有無の目安とすることができる手段をいう。例えば、口臭の有無をハリメーター(モリタ社製)等の口臭測定機器で定量的に測定しておき、当該定量値と沈殿率との相互関係をデータとして蓄積しておけば、測定した沈殿率等の不溶性物質量を口臭の有無の指標とすることが可能となる。この場合においては、「唾液性状検査用キット」に含まれる「不溶性物質量により唾液性状を評価する手段」の一例としては、口臭の程度と沈殿率等との関係を示すデータシートを挙げることができる。
【0023】
本発明に係る第2の唾液性状検査用キットは、唾液を装入する透明容器、該唾液の濁度を測定する手段、および該濁度により唾液性状を評価する手段を有する。
【0024】
「唾液を装入する透明容器」は、前述した「一定量の唾液を装入する透明容器」と同様のものを使用することができるが、濁度のみを測定する場合等には、必ずしも一定量を量り採る必要はない。
【0025】
「唾液の濁度を測定する手段」は、簡便に濁度を測定できるものであれば特に制限なく使用することができる。例えば、一定厚みの採取唾液を通しての印刷された記号や模様の見え具合により判定するという、従来用いられている方法を使用することができる。しかし、本発明では図1に示す様に、濃色太線と濃色〜白のグラデーション線を並列させた濁度判定用見本を用いれば、簡便でより客観的な判断が可能となる。即ち、唾液中に含まれる不溶性物質は一般的に白色であるので、採取唾液を濃色線上にかざせば、その濁度が濃いほど透過して見える色は白色に近づき、唾液が不溶性物質で占められている場合には光は透過せず白色に見えることとなる。この透過光とグラデーション線上の色とがほぼ一致する点をスコアの点数として読み取れば、測定結果を数値として得ることが可能となる。ここで「濃色」は、濃色から白色へのグラデーションが明確に表現できる色であれば特に制限されないが、例えば黒,緑,青,赤を挙げることができ、最も好適に使用されるのは黒である。
【0026】
「濁度により唾液性状を評価する手段」は、「不溶性物質量により唾液性状を評価する手段」と同様に、例えば、口臭の定量値と濁度との相互関係をデータとして蓄積しておき、これを測定した濁度の標準とするようにすればよい。この場合における「濁度により唾液性状を評価する手段」の一例としては、口臭の程度と濁度との関係を示すデータシートを挙げることができる。
【0027】
本発明の唾液性状検査用キットは、一定唾液量に含まれる不溶性物質量と唾液濁度の両方を測定できるものであってもよい。即ち、この場合の唾液性状検査用キットは、上記で説明した「一定量の唾液を装入する透明容器」、「該唾液中に含まれる不溶性物質の量を測定する手段」、および「該唾液の濁度を測定する手段」を有し、更に測定した不溶性物質量と濁度により唾液性状を評価する手段を必須要素として含むものである。
【0028】
また、本発明の唾液性状検査用キットは、「唾液の色調を測定する手段」を有していてもよい。つまり、本来唾液は無色透明であるが、歯肉炎や口内炎等に伴う出血によって薄桃色となり、出血が甚だしい場合には薄褐色まで着色する。また、口臭の原因の一つであるアミン化合物や膿等により薄黄色に着色することもある。更に、カレー,キムチ等の食物やコーヒー,タバコ等の嗜好品によっても唾液は着色し、これらは直接に口臭の原因となる。従って、キット中に印刷等された色調判定用見本を含めておき、これと採取唾液の色調とを比較することによって、口腔内疾患や口臭の有無を判断することが可能となる。
【0029】
本発明に係る口腔内疾患判定方法は、一定量の採取唾液中に含まれる不溶性物質量で口腔内疾患の有無を判定するものと、採取唾液の濁度により口腔内疾患の有無を判定するものである。
【0030】
即ち、本発明の方法は、「唾液中に含まれる不溶性物質は、口腔内粘膜および舌上皮細胞の剥離したものや口腔微生物等の細胞成分が主であり、この不溶性物質の量や唾液の濁度を測定すれば口腔内疾患や口臭の有無を判定できる」との新しい知見により完成されたものであり、前述した唾液性状検査用キットの各構成要素の説明に準じて実施することができ、口腔内疾患の有無、ひいては口臭の有無を判定することができる。
【0031】
本発明は以上のように構成されており、本発明によれば、唾液を採取してその性状を評価するという非常に簡便かつ簡易な手段によって口腔内疾患や口臭の有無を判定することができる。
【0032】
次に、本発明に係る唾液性状検査用キットに含まれる「判定用見本」の一例を、模式図として図2に示し、当該図を用いてその使用方法を説明する。
【0033】
(濁度の測定)
一定量の唾液を「透明容器」に採取し、濁度を測定する。図2の模式図では、「濁度判定用見本部」Aの上部の黒太線上に「透明容器」をかざして下部のグラデーション線の色と比べることにより濁度をスコアとして測定する方法を採用している。
【0034】
(沈殿量の測定)
唾液を採取した「透明容器」を一定時間静置し、「沈殿量測定部」Bにより唾液量と沈殿量を読み取って、唾液量に対する沈殿量の割合を不溶性物質量の目安とすることができる。

(色調の測定)
唾液を採取した「透明容器」を一定時間静置し、「判定用見本」の白色背景に「透明容器」の上澄み部分をかざして「色調判定用見本部」Cの色調と比べることによって、唾液の色調を判定することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a saliva property testing kit that can easily determine the presence or absence of dental caries, periodontal disease, stomatitis, candida infection and the like, and the presence or absence of halitosis associated therewith, and a method for determining the presence or absence of an oral disease.
[0002]
[Prior art]
In recent years, with changes in lifestyle such as eating habits and the aging of society, problems related to infectious diseases such as dental caries, periodontal disease, stomatitis, candida infection, and oral problems such as bad breath accompanying these are increasing. It is increasing.
[0003]
The type and degree of progress can be known by a doctor's diagnosis or examination, but if a disease is not manifested as a subjective symptom, or if there is a low awareness that the disease is one of the causes, an expert in bad breath judgment It is preferable that the evaluation can be performed easily without the assistance of the user.
[0004]
By the way, saliva is not only odorless by nature, but also has a buffering action to reduce a decrease in oral pH that promotes caries, and lysozyme, lactoferrin, and IgA which is an immunoglobulin that prevents and reduces bacterial and fungal infections. And the like, and also has an action of cleaning bacteria and odorous substances in the oral cavity. Accordingly, a technique for measuring the amount of saliva and its viscosity to determine the state in the oral cavity has been developed, based on the idea that the amount of saliva secreted is an indicator of the presence or absence of oral diseases and bad breath.
[0005]
For example, Patent Literature 1 discloses a saliva testing tool that can determine the amount and viscosity of saliva. The device is made of a permeable support, and the amount of saliva and its permeability, penetration rate, and viscosity can be easily determined.
[0006]
However, such a device can only measure the amount of saliva and the like, and cannot directly determine the presence or absence of oral diseases or bad breath.
[0007]
[Patent Document 1]
Japanese Patent Application Laid-Open No. 2000-329763 (Claim 1 etc.)
[0008]
[Problems to be solved by the invention]
Under the circumstances as described above, the problem to be solved by the present invention is that the presence or absence of oral diseases and accompanying bad breath can be determined with higher accuracy than conventional simple methods, and in the absence of expert assistance. It is an object of the present invention to provide a technique that can be easily and simply implemented.
[0009]
[Means for Solving the Problems]
The present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result of progress of oral diseases, that is, with the growth of causative bacteria such as dental caries and periodontal disease, insoluble substances due to their metabolism increase. Based on this new finding, the inventors have found that measuring the amount of insoluble substances contained in saliva can be a measure of oral diseases and the presence or absence of bad breath associated therewith, and have completed the present invention.
[0010]
That is, the saliva property testing kit according to the present invention is a transparent container for charging a certain amount of saliva, means for measuring the amount of insoluble substance contained in the saliva, and evaluates saliva property by the amount of the insoluble substance. It is characterized by having means.
[0011]
In addition, since there is a correlation between the amount of insoluble substances contained in saliva and the turbidity of saliva, the saliva property testing kit of the present invention is a transparent container into which saliva is loaded, and measures the turbidity of the saliva. And means for evaluating saliva properties based on the turbidity.
[0012]
Furthermore, the saliva property testing kit of the present invention can measure both the amount and turbidity of an insoluble substance contained in saliva, that is, a transparent container into which a certain amount of saliva is charged, May have means for measuring the amount of the insoluble substance contained in the above, means for measuring the turbidity of the saliva, and means for evaluating the salivary properties based on the amount of the insoluble substance and the turbidity.
[0013]
The above-mentioned saliva property testing kit includes a means for measuring the color tone of saliva, so that a more multifaceted determination of intraoral diseases and the like can be made.
[0014]
Further, the method for determining an oral disease according to the present invention determines the presence or absence of an oral disease based on the amount of insoluble substance contained in a fixed amount of collected saliva, or determines the presence or absence of an oral disease based on the turbidity of the collected saliva. It is characterized by doing.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
The greatest feature of the saliva property testing kit and the method for determining an oral disease according to the present invention is that an oral disease or bad breath is achieved only by a very simple operation of measuring the amount of insoluble substance contained in saliva or its turbidity. The point is that the presence or absence can be determined. That is, there has been a technique for easily determining the presence or absence of dental caries and the oral environment by measuring the pH and buffering capacity of saliva and the presence of oral disease-causing bacteria in saliva. Based on new knowledge that the amount of insoluble substances contained in saliva or the turbidity of saliva and the degree of progress of oral diseases are closely related, the presence or absence of intraoral diseases etc. can be easily and more accurately determined. This allows the judgment.
[0016]
Hereinafter, embodiments of the present invention exhibiting such characteristics and effects thereof will be described.
[0017]
The first saliva property test kit according to the present invention is a transparent container for charging a fixed amount of saliva, a means for measuring the amount of insoluble substance contained in the saliva, and evaluating the saliva property by the amount of the insoluble substance. It has means to do.
[0018]
The “transparent container into which a fixed amount of saliva is charged” may be any transparent container into which a fixed amount of saliva can be charged and from which the properties of the collected saliva can be observed from the outside. In addition, the volume is sufficient if it is about 5 ml or less, corresponding to the general amount of saliva that can be collected in a few minutes, and a scale indicating the amount of collected saliva may be attached. May be provided on the bottom surface or side surface, and if it has a more elongated shape, it is easy to measure the precipitation rate of insoluble substances, but the scope of the present invention is not limited to these. . However, if the inner diameter is excessively large, it may be difficult to quantify the insoluble substance. Therefore, the inner diameter is preferably about 1 cm or less. Examples of such a “transparent container into which a certain amount of saliva is charged” include a small test tube and a test tube.
[0019]
The saliva may be collected directly into a “transparent container into which a fixed amount of saliva is to be placed” in which the upper portion is formed into a shape (eg, a funnel) for easily collecting saliva. It is convenient to compare a plurality of samples because they can be easily collected by measuring the amount and placing it in a “transparent container that holds a certain amount of saliva”.
[0020]
“Saliva” includes resting saliva that is constantly secreted without special stimulation, and stimulated saliva that is secreted by stimulation such as mastication, and both can be used in the present invention. However, when examining a plurality of subjects, it is desirable to unify whether it is saliva at rest or stimulated saliva. This is because saliva properties may vary depending on the type. Further, in general, stimulated saliva is easy to use from the viewpoint of the amount of collection. Furthermore, since saliva properties and the like are easily affected by a meal, it is preferable to determine a collection time for saliva and the like a certain time after a meal.
[0021]
`` Means for measuring the amount of insoluble substance contained in saliva '' is not particularly limited as long as it can objectively measure the amount of insoluble substance contained in a certain amount of saliva, for example, filtering collected saliva After that, the amount of the insoluble substance may be measured. However, in order to prevent the “turbidity” described below from being measured after filtration or to more easily measure the amount, it is preferable to measure the precipitation rate in the present invention. The measurement of the “sedimentation rate” does not necessarily have to be strict. For example, a fixed amount of collected saliva is allowed to stand for a certain period of time, and the total saliva amount (even if the saliva height in the “transparent container”). Calculated as a ratio of the amount of the precipitated part to the amount of the precipitated part (similarly, the amount of the precipitated part in the “transparent container”). A centrifugal separator or the like may be used to promote the precipitation, but it is preferable to leave it still for easy and simple evaluation.
[0022]
Even if the type of oral disease cannot be specified, the amount of insoluble substance measured by `` means for measuring the amount of insoluble substance contained in saliva '' can be objectively measured for oral diseases such as dental caries and associated bad breath. Means that can be used as a measure of presence or absence. For example, if the presence or absence of bad breath is quantitatively measured by a bad breath measuring device such as a harimeter (manufactured by Morita) and the correlation between the quantitative value and the precipitation rate is accumulated as data, the measured precipitation rate can be measured. And the like can be used as an indicator of the presence or absence of bad breath. In this case, as an example of the “means for evaluating saliva properties based on the amount of insoluble substances” included in the “saliva property test kit”, a data sheet showing the relationship between the degree of bad breath and the precipitation rate and the like may be mentioned. it can.
[0023]
A second saliva property testing kit according to the present invention has a transparent container into which saliva is charged, means for measuring the turbidity of the saliva, and means for evaluating the salivary properties based on the turbidity.
[0024]
As the “transparent container for loading saliva”, the same “transparent container for loading a certain amount of saliva” described above can be used, but when measuring only turbidity, etc. There is no need to weigh.
[0025]
The “means for measuring turbidity of saliva” can be used without particular limitation as long as it can easily measure turbidity. For example, a conventionally used method of determining by the appearance of a printed symbol or pattern through a collected saliva having a certain thickness can be used. However, in the present invention, as shown in FIG. 1, a simple and more objective judgment can be made by using a sample for turbidity judgment in which a thick dark line and a gradation line from dark to white are arranged in parallel. That is, since the insoluble substance contained in saliva is generally white, if the collected saliva is held over a dark line, the color that is seen through the darker the turbidity becomes closer to white, and the saliva is occupied by the insoluble substance. In this case, light does not pass through and looks white. If a point at which the transmitted light substantially matches the color on the gradation line is read as the score of the score, the measurement result can be obtained as a numerical value. Here, the “dark color” is not particularly limited as long as it is a color that can clearly express a gradation from dark color to white, but examples thereof include black, green, blue, and red. Is black.
[0026]
`` Means for evaluating saliva properties by turbidity '' is, for example, as in `` means for evaluating saliva properties by insoluble substance amount '', for example, the correlation between the quantitative value of halitosis and turbidity is stored as data, This may be used as a standard for the measured turbidity. As an example of the “means for evaluating saliva properties by turbidity” in this case, a data sheet showing the relationship between the degree of bad breath and turbidity can be mentioned.
[0027]
The saliva property testing kit of the present invention may be one that can measure both the amount of insoluble substance and the salivary turbidity contained in a fixed amount of saliva.

【Example】
Hereinafter, the present invention will be described in more detail with reference to Examples and Test Examples, but the scope of the present invention is not limited thereto.
[0037]
(Example 1)
At the time of the first consultation, 21 subjects (age: 5 males, 16 females) at the age of 19 to 60 who complain of bad breath were checked for bad breath by a sensory test, and then the amount of saliva, the turbidity of saliva, and the sedimentation rate were measured. Bad breath was measured using a halimeter as a measuring instrument.
[0038]
After the initial consultation, oral physiology recovery training for each subject, lifestyle and dietary guidance, toothbrush immediately after getting up and just before going to bed using Excellent Breath Toothpaste (Margaret Josephine), and using Celabres mouthwash (AlfaNet) The morning and evening gargle was performed for 3 weeks.
[0039]
After completion of the halitosis treatment for 3 weeks, the same measurement as that at the time of the first medical examination was performed. The results are shown in Table 1 below.
[0040]
[Table 1]
Figure 2004108976
[0041]
* 1: The subject was made to open his / her mouth and hold his / her breath, and the odor generated in the oral cavity was directly sucked through the nose, and the smell was smelled to check for bad breath.
[0042]
* 2: Saliva generated for 5 minutes without chewing anything was collected in a measuring cup, and the amount of saliva was measured.
[0043]
* 3: The saliva when measuring the amount of saliva was placed in a test tube having an inner diameter of 10 mm, placed on the thick black line of the “sample for turbidity determination” shown in FIG. 2, and the thick black line was almost intact depending on the appearance of the thick black line. The cases from visible to completely invisible were examined in four stages (0, 1, 2, 3).
[0044]
* 4: The test tube whose turbidity was measured was placed on a stand and allowed to stand for 10 minutes, and the amount of saliva and the amount of sediment were read and calculated by the following equation.
[0045]
Precipitation rate (%) = [precipitation amount (ml)] / [saliva amount (ml)] × 100
From the above results, there is a close correlation between the turbidity of saliva and the amount of insoluble substances (precipitation rate) and bad breath, and according to the saliva property testing kit of the present invention, the salivary property It was revealed that properties such as turbidity could be measured.
[0046]
【The invention's effect】
The method for determining an oral disease of the present invention can determine the presence or absence of an oral disease and its associated bad breath by a very simple and simple means of collecting saliva and measuring the amount or turbidity of the insoluble substance contained therein.
