Radiation Protection – Comparison CaviTAU & X-ray

Startseite About CaviTAU® Radiation Protection – Comparison CaviTAU & X-ray

CaviTAU® is Patient Protection in Action

CaviTAU® is the physical novelty without radiation exposure. Since the invention of X-rays and MRT, the CaviTAU® application has been a physically completely new development of imaging information acquisition in dentistry for the first time.

CaviTAU® – Diagnostic Superiority to X-rays

CaviTAU® provides further added value in image quality compared to x-rays through extensive recording of the bony structures in old extraction and surgical wounds, in the vicinity of endodontically treated teeth and dental implants.

CaviTAU® – Focus on Benefits for Professionals & Patients

CaviTAU® focuses on benefits for patients and specialist staff: Radiation-free and stress-free, inexpensive and easy to use, and providing completely new aspects of previously unrecognized pathologies.

CaviTAU® – Environment and Radiation Protection

By developing CaviTAU®, we are taking responsibility and protecting people and the environment from radiation.

The use of CaviTAU® is completely harmless because it avoids ionising X-rays. Due to the known health hazards caused by X-rays, the legislature has passed legislation to control exposure to X-rays.

The German Radiation Protection Act (Strahlenschutzgesetz, StrlSchG) forms the comprehensive autonomous national legal basis for protection from ionising radiation in Germany. The majority of the act enters into effect from 1 October 2017, with the rest of the act entering into force as of 31 December 2018. The aim of the act is to keep patients’ exposure to radiation as low as possible. Through CaviTAU®, we have created a practical alternative to radiation.

One of the guiding principles of radiation protection is the ALARA principle (As Low As Reasonably Achievable) in response to dealing with ionising radiation.

[Revised version of the German X-ray Regulation (Röntgenverordnung) as per the Federal Republic of Germany’s medical legislation, dated 1 January 2015 (Art. 10 of the Regulation of 11 December 2014].

In principle, research shows that there is a potential hazard every time X-rays are used. The intensity of the radiation is measured through the dose rate. Any ionising radiation that reaches a living cell can cause damage.

Götz B et al. Medizinisch nit indiziertes Röntgen. In: MedR 1998, Heft 11, S.506.

It is calculated that every German resident receives an average effective dose of two millisieverts per year (mSv/a) solely from X-ray diagnostics. This figure is four times higher than in the US and twice as high as in France and Switzerland, the two countries ranking behind Germany in the statistics.

[Wandtner R. Der duchstrahlte Patient. In: FAZ vom 27.08.2003 / Nr. 198; Bethge P. Strahlender Bilderregen. In: Der Spiegel 36/2003, S 136-137

The effective dose of the three procedures panoramic OPG, digital volume tomogram DVT, and computed tomography (CT) is about 1: 10: 100 [1, 2]. In the end, the use of ALARA’s principle means above all, that unnecessary examinations and duplicate examinations are to be avoided. Consequently, if no evidence of osteopathy can be reliably detected even on an OPG or 3D-CBCT scan, with the help of CaviTAU® it is possible to avoid a DVT scan or computed tomography that has a hundred fold radiation exposure compared to a conventional 2D scan, assuming anamnestic suspicion. The CaviTAU® measurement as the third imaging procedure has to be booked in contrast to OPG, DVT and the CT with zero emission load. The completely uncompromising CaviTAU® ultrasound measurement is therefore suitable for measuring bone density, to avoid further diagnostically induced radiation exposure (DVT, CT, scintigraphy or similar) in the sense of §15. A possible rejection of the uncompromising CaviTAU® ultrasound measurement on the part of payers and appraisers thus equates to an indirect request to violate §15 Strahelnschutzgesetz and hinders the avoidance of an unnecessary bodily injury according to §15 Radiation Protection Act.

Summary of these clinical studies:

“TAU was proven to be accurate at more than 99.99% in all cases totaling over 3,742 patients in peer reviewed studies. Comparing the TAU to X-Ray and enhanced MRI, the TAU was more than 2 times as accurate than the MRI and 3 times more accurate the X-Ray.”

The current S3 guideline on odontogenic infections, valid until: September 2021 is edited under the leadership of the German Society of Oral and Maxillofacial Surgery (DGMKG) and the German Society of Dental, Oral and Maxillofacial Surgery (DGZMK): This guideline is documented in 7.2.2. Imaging diagnostics for odontogenic infections with a tendency to spread: Evidence-based recommendation:
„The ultrasound examination provides a simple and efficient method to detect a smearing of an odontogenic infection and to estimate a possible spread of the odontogenic infection”
