[The medical history through a list of medical risks. Practical use in dental medicine]

A medical risk related patient-administered history (MRRH) was developed for use in routine dental treatment with or without local anesthesia by the general dental practitioner. The fixed guidelines of the ASA classification may be under discussion. Of course, there are other divisions and combinations conceivable and deviation of the standards may be inevitable. However, the present proposal is to be used for investigation purposes, which makes fixed guide-lines imperative. This MRRH, tested in Belgium, proved to be valid in comparison with the "gold standard", a verbal history taken by a physician experienced in pre-assessment control. The most reliable results can be obtained by a combination of the medical questionnaire and the additional verbal history.
