Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Erkennen von Zahnkaries und insbesondere auch zum Erkennen einer einzelnen von Karies befallenen Stelle an einem Zahn im Frühstadium.The The invention relates to a method and a device for detecting of dental caries and in particular also for recognizing an individual caries-infested spot on an early-stage tooth.
Zahnkaries ist die häufigste Zahnkrankheit infolge von Substanzverlust an Zahnhartgeweben durch einen chronisch zersetzenden Prozess. Ausgangspunkt der Zahnkaries ist bakterieller Zahnbelag, unter dessen demineralisierendem Einfluss sich die Zahnkaries zunächst als weißer Fleck zeigt. Fortschreitend erweicht dann die Zahnhartsubstanz.dental caries is the most common Tooth disease as a result of loss of substance to dental hard tissues a chronically decomposing process. Starting point of the dental caries is bacterial plaque, under whose demineralizing influence the dental caries first as white Spot shows. Progressively softens then the hard tooth substance.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung anzugeben, mit deren Hilfe es möglich ist, Zahnkaries bereits in einem frühen Stadium ihrer Bildung zu erkennen.Of the Invention is based on the object, a method and an apparatus to indicate with whose help it is possible Dental caries is already at an early stage of its formation too detect.
Zur Lösung dieser Aufgabe sieht die Erfindung mit den Merkmalen von Patentanspruch 1 vor, dass die in der Mundhöhle befindliche Luft bzw. gasförmige Mikroflora auf karies-typische Moleküle/Gasanteile untersucht bzw. analysiert wird und dass das Ergebnis angezeigt wird.to solution This object is achieved by the invention with the features of claim 1, that in the oral cavity air or gaseous Microflora examined for caries-typical molecules / gas components or is analyzed and that the result is displayed.
Die Lösung des Problems beruht somit auf der Erkenntnis, dass die gasförmigen Umwandlungsprodukte beim Vorhandensein von Zahnkaries bzw. von kariesverursachenden Bakterien andersartig sind als andere, geruchsbildende Verursacher im Bereich der Mundhöhle. Es geht aus diesem Grund darum, festzustellen, ob kariesbedingte, gasförmige Produkte grundsätzlich in der Mundhöhle vorhanden sind und in Weiterbildung der Erfindung wird unmittelbar die mit Zahnkaries befallene Stelle/Stellen von einem oder mehreren Zähnen genau lokalisiert, wobei dies auch bereits in einem Frühstadium geschieht.The solution the problem is thus based on the knowledge that the gaseous conversion products in the presence of dental caries or caries-causing Bacteria are different than other, odiferous causative agents in the area of the oral cavity. It is therefore important to determine whether caries-related, gaseous products in principle in the oral cavity are present and in development of the invention becomes immediate the body / site of one or more infested with dental caries tooth precisely localized, and this also already at an early stage happens.
In Weiterbildung der Erfindung ist ferner vorgesehen, dass die Anzeige für das Vorhandensein bestimmter Gasprodukte optisch und/oder akustisch erfolgt.In Further development of the invention is further provided that the display for the Presence of certain gas products visually and / or acoustically.
Die Vorrichtung zum Erkennen von Zahnkaries umfasst erfindungsgemäß eine mundgerechten Gasanalysator und eine Anzeigeeinrichtung.The According to the invention, a device for detecting dental caries comprises a bite-sized gas analyzer and a display device.
In Weiterbildung der Erfindung ist ferner vorgesehen, dass die Vorrichtung zugleich auch eine mundgerechte Sammeleinrichtung aufweist.In Further development of the invention is further provided that the device at the same time also has a bail-matched collecting device.
Die Gasprüfeinrichtung und die Anzeigeeinrichtung und ggf. zugleich auch die Gassammeleinrichtung sind derart zu einem kompakten Gerät zusammengefasst, dass der Proband das Ergebnis unmittelbar während der Untersuchung erhält. Dabei ist das Gerät derart klein und handlich, dass es auch unmittelbar im Bereich der Mundhöhle verwendet werden kann.The Gasprüfeinrichtung and the display device and possibly also the gas collection device at the same time are summarized in such a compact device that the Subject receives the result immediately during the examination. there is the device so small and handy that it is also directly in the field of oral cavity can be used.
Die Erfindung stellt somit ein Verfahren und eine Vorrichtung – auch zur Früherkennung – von Zahnkaries zur Verfügung, so dass es möglich ist, einen kariösen Befall eines Zahnes sofort zu erkennen und vollständig zu beheben. Grundsätzlich ist es bekannt, Karies auf optischem Wege oder auch auf andere Weise zu identifizieren, wobei Voraussetzung jedoch bisher war, dass die Zahnkaries bereits relativ weit fortgeschritten ist. In diesen bekannten Fällen war es regelmäßig notwendig, noch weiteres Zahnmaterial zu entfernen und die Zahnöffnung mit einem Ersatzwerkstoff zu füllen bzw. zu schließen. Im Gegensatz dazu lässt sich erfindungsgemäß eine beginnende Zahnkaries in einem extrem frühen Stadium erkennen, so dass dann grundsätzlich bekannte sowie gute Behandlungsmethoden zur vollständigen Behebung des Schadens gezielt eingesetzt werden können.The Invention thus provides a method and an apparatus - also for Early detection - of dental caries to disposal, so that it is possible is a carious Immediately detect infestation of a tooth and completely closed remedy. in principle It is known, caries by optical means or otherwise However, the prerequisite was that the Dental caries is already relatively advanced. In these known Cases was it is necessary regularly to remove more tooth material and the tooth opening with to fill a replacement material or close. In contrast, lets according to the invention an incipient Dental Caries in an Extremely Early Recognize stage, so that then basically known as well as good Treatment methods for complete correction the damage can be used specifically.
Wesentlich ist in diesem Zusammenhang schließlich, dass auch eine Zahnkaries an nicht sichtbaren Stellen, wie zum Beispiel im Bereich von Zahnzwischenräumen und an und unter Zahnersatz, früher als bisher und insbesondere auch im Frühstadium erkannt und lokalisiert werden können. Bei herkömmlichen Erkennungsverfahren, wie z.B. beim Röntgen, ist ein Befall erst dann zu lokalisieren, wenn ca. 30% des Zahnmaterials bereits durch Zahnkaries zerstört sind.Essential In this context, finally, that is also a dental caries in non-visible areas, such as in the area of interdental spaces and on and under dentures, earlier detected and localized as before and especially at an early stage can be. In conventional detection methods, such as. at the x-ray, is an infestation to locate only when about 30% of the tooth material already destroyed by dental caries are.
