Abstract
The invention relates to a method for detecting dental cavities, enabling the detection of dental cavities at a very early stage using especially simple means. According to the invention, the air or gaseous microflora in the oral cavity is examined and analysed for gas constituents or molecules typical of cavities and the result is then displayed.
Description
Beschreibung Verfahren und Vorrichtung zum Erkennen von Zahnkaries Description Method and device for detecting dental caries
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 invention relates to a method and a device for recognizing dental caries and, in particular, also for detecting a single caries-affected area on a tooth in the early stage.
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 dental disease due to loss of substance to dental hard tissues due to a chronic disintegrating process. The starting point of dental caries is bacterial plaque, under the demineralizing influence of which the dental caries first appears as a white spot. 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.The invention has for its object to provide a method and a device by means of which it is possible to recognize dental caries already at an early stage of their formation.
Zur Lösung dieser Aufgabe sieht die Erfindung mit den Merkmalen von Patentanspruch 1 vor, dass die in der Mundhöhle befindliche Luft bzw. gasförmige Mi- kroflora auf karies-typische Moleküle / Gasanteile untersucht bzw. analysiert wird und dass das Ergebnis angezeigt wird.To achieve this object, the invention with the features of claim 1 provides that the air or gaseous microflora located in the oral cavity is examined or analyzed for caries-typical molecules / gas fractions 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.
In Weiterbildung der Erfindung ist ferner vorgesehen, dass die Anzeige für das Vorhandensein bestimmter Gasprodukte optisch und/oder akustisch erfolgt.The solution to the problem is thus based on the finding that the gaseous conversion products in the presence of dental caries or caries-causing bacteria are different than other, odor-causing causative agents in the oral cavity. It is therefore for this reason to determine whether caries-related, gaseous products are basically present in the oral cavity and in the invention of the invention directly infected with dental caries body / points of one or more teeth is precisely located, and this is already happening in an early stage , In a further development of the invention, it is further provided that the display for the presence of certain gas products takes place optically and / or acoustically.
Die Vorrichtung zum Erkennen von Zahnkaries umfasst erfindungsgemäß eine mundgerechten Gasanalysator und eine Anzeigeeinrichtung.The device for detecting dental caries comprises according to the invention 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 a further development of the invention it is further provided that the device also has a bite-sized collection device at the same time.
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 gas testing device and the display device and possibly also the gas collecting device are combined in such a compact device that the subject receives the result directly during the investigation. The device is so small and handy that it can also be used directly in the area of the oral cavity.
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 a device - also for early detection - of dental caries available, so that it is possible to detect a carious involvement of a tooth immediately and completely remedy. Basically, it is known to identify caries optically or in other ways, with the condition, however, has been that the dental caries is already relatively advanced. In these known cases, it was regularly necessary to remove even more tooth material and fill the tooth opening with a replacement material or close. In contrast, according to the invention, incipient dental caries can be recognized at an extremely early stage, so that fundamentally well-known and good treatment methods can be used in a targeted manner to fully repair the damage.
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.
It is essential in this context, finally, that a dental caries in non-visible areas, such as in the field of interdental spaces and on and under dentures, earlier than previously and especially at an early stage can be detected and located. In conventional Detection method, such as the X-ray, an infestation is only localize when about 30% of the tooth material is already destroyed by dental caries.
