Opinions from the participants

  1. Although it is revealed that an intraoral disease is intimately related with whole body, there is little study and approach in the field of dentistry, and the evidence is not made apparent yet.
    In hope for the further studies of dentists and I think educational organizations are needed in the future.
    As the result of these attempts, and systematic the future of dentistry could be built newly.
  2. It gives a new direction of dentistry in the future to changing from subjective evaluation to scientific and objective evaluation, while it has often been influenced by the study and the quality of the specialty, in other words, apprenticeship-like technique in the past dentistry.
  3. In the past dentistry, at formality was regarded important tended to assume all if form was regulated well.
    However, we may not solve the problem if we do not turn our consciousness to existing lifestyle, and child care, the environment including the growth behind intraoral various symptoms and illness to develop in a growth process.
    In our body, constancy must be kept while feeding back by an antagonistic system of the muscle balance, and adjusting it.
    Therefore, I think that big viewpoints of neurophysiology are necessary to handle in the oral cavity.
  4. A device detecting the activation of the cranial nerve domain controlling the excellent unpleasantness of the frontal lobe was used this time by adjustment work for the crown restoration, but because it detects only high occlusion, it is not much effective.
    However, if the pleasantness and unpleasantness under the consciousness is detectable, I think that this device can become epoch-making.
  5. Up until now, the checking of the occlusion of crown restoration and the denture has been performed using an extremely thin articulating paper mainly, but it is based on empirical technique and tends to be lacking in objectivity.
    It must be desirable to become study the medical care based on scientific data and information of brain and nerve.
  6. As the device uses chewing cycle, it is an exercise of associated organizations which are approximately equal to real chewing.
    Therefore unknown information until now may be more likely to be provided.
    I think that we must consider oral medicine in scientifically corresponding brain function in the future.

Katayama seminar by making use of the video

Video Show of the seminars

The Katayama seminar (seminar of 30 hours for four days in total) began in 1981was held 30 times in total, and was completed in 1996.
Fortunately, the valuable lectures were recorded in videos.

Meetings to see those videos were already held over four times till 2006.
The sound of video is surprisingly good, and photographs over 1,600 slides covering 30 cases are digitalized one by one moderately, and, it seems you are actually listening the lecture of Dr. Katayama really.
The people participated for the first time talked about an impression that they never had seen such a great thinker in the world of dentistry.

In addition, there are quite a few participation of person over 60 years old who wish to review the clinical practice once again and want to make it fresh start of their practice. There are some such people

The lecture of Dr. Katayama talking about the true dentistry that nobody has taught him in the new viewpoints enthusiastically has not lost brightness regardless of the passing of time.
And it reminds a participant of new impression and self-respect whenever it repeats the number of times.
