Description
Die Neuerung betrifft einen Diagnoselichtstift für &ggr; Approximelkeriee. |The innovation concerns a diagnostic light pen for &ggr; Approximel chemotherapy. |
Kariesdiagnostik ist an einsehbaren Gebieten für den | Zahnarzt. relativ einfach, da ein Substanzverlust und/oder eine Farbveränderung mit den üblichen MittelnCaries diagnosis is relatively easy for the dentist in visible areas, since a loss of substance and/or a change in colour can be detected using the usual means.

Problematischer ist die Diagnose in Gebieten, die nicht einsehbar oder dem Zugang der Sonde nicht zugänglich sind. (Approximalkaries und schmelzunterminierende Defekte)Diagnosis is more problematic in areas that cannot be seen or are not accessible to the probe (approximal caries and enamel-undermining defects).
Da der Strukturverlust des Dentins zur Veränderung der optischen Eigenschaften führt, stellen sich diese Läsionen im Röntgenbild als Aufhellungen dar. Eine andere Darstellungsmöglichkeit bietet die Diaphanoskopie, bei der die unterschiedlichen Transparenz- und Transluzenzeigenschaften zwischen gesundem und krankem Zahnhartgewebe zur Diagnostik herangezogen werden können. Im Frontzahnbereich kann das Licht der Behandlungseinheit dazu benutzt werden. Im Seitenzahnbereich ist dies nicht möglich, da das Licht nicht in den Approximalraum gelangt. Glasfaseroptiken mit extraoralen Lichtguellen können Abhilfe schaffen. Sie sind aber sehr teuer und aufwendig, da die Länge des Lichtleiters hohe Lichtintensitäten notwendig macht. Zudem stellt die Sterilisation von Glasfaserkabeln ein ein Problem dar, da die zur Verfügung stehenden Sterilisationsmethoden zur Einschränkung der optischen Eigenschaften des Lichtleiters führen. Eine Desinfektion, die dieses Problem nicht auftreten läßt, ist sicherlich nicht ausreichend, da das Glasfaserende mit pathogenen Keimen in Kontakt kommt.Since the loss of structure in the dentin leads to a change in the optical properties, these lesions appear as lightening in the X-ray image. Another possible way of imaging is diaphanoscopy, in which the different transparency and translucency properties between healthy and diseased dental hard tissue can be used for diagnosis. In the anterior tooth area, the light from the treatment unit can be used for this purpose. In the posterior tooth area, this is not possible because the light does not reach the approximal space. Fiber optics with extraoral light sources can provide a solution. However, they are very expensive and complex because the length of the light guide requires high light intensities. In addition, the sterilization of fiber optic cables is a problem because the available sterilization methods lead to a restriction of the optical properties of the light guide. Disinfection that does not allow this problem to occur is certainly not sufficient because the end of the fiber optic cable comes into contact with pathogenic germs.

Der Neuerung liegt die Aufgabe zugrunde, einen preiswerten, netzunabhängigen Diagnoselichtstift zu schaffen, der leicht zu handhaben ist und keine Sterilisationsprobleme aufwirft.The innovation is based on the task of creating an inexpensive, mains-independent diagnostic light pen that is easy to handle and does not pose any sterilization problems.
Die weitere Ausbildung des Neuerungsgegenstandes geht aus den Unteransprüchen hervor.The further development of the subject matter of the innovation emerges from the subclaims.
- der Preis kann durch das einfache Konstruktionsprinzip gering gehalten werden;- the price can be kept low thanks to the simple design principle;
- die integrierte Stromversorgung macht den Zahnarzt vom Stromnetz unabhängig;- the integrated power supply makes the dentist independent of the power grid;
das kurze Stück Lichtleiter, das mit dem Approximalraum in Kontakt kommt, kann als kostengünstiger Wegwerfartikel konzipiert werden, da für die kurze Wegstrecke auch Leiter mit nicht optimalen optischen Eigenschaften verwandt werden können. Durch überstreifen eines Fingerlings kann eine Kontamination des Lichtstabes vermieden werden. Sterilisationsprobleme werden so umgangen.The short piece of light guide that comes into contact with the proximal space can be designed as a cost-effective disposable item, since even guides with less than optimal optical properties can be used for the short distance. Contamination of the light rod can be avoided by slipping a finger cot over it. Sterilization problems are thus avoided.
Der Diagnoselichtstift für Approximalkaries bietet eine Alternative zu den bisher notwendigen Röntgenaufnahmen in der täglichen Praxis. Durch seine speziellen Vorteile eignet er sich besonders für den Einsatz bei Screeinguntersuchungen z.B. in Kindergärten und Schulen.The diagnostic light pen for approximal caries offers an alternative to the X-rays that were previously necessary in daily practice. Due to its special advantages it is particularly suitable for use in screening examinations, e.g. in kindergartens and schools.
