[The use of photo-acoustic stimulation in dental practice].

Photo-acoustic stimulation provides a powerful stimulation of the central nervous system, whereas it relaxes the body. Authors found it useful to eliminate simple anxiety, and to reduce salivary secretion in the oral cavity. The combination of photo-acoustic stimulation with hypnotic techniques has been found as an excellent method to treat oro-facial psychogenic symptoms and denture intolerance. In the case of odonto-phobic patients, the combined method has been found less effective than hypnotic techniques alone.
