Abstract
The purpose of this study is to obtain opinions from medical doctors about particular problems in dental treatment for medically compromised patients. Questionnaire was administered to 186 medical doctors in 24 hospitals which locate in the middle part of Nagano Prefecture. The answer was obtained from 43 percent of the doctors (n=87). The result revealed the fact that 30 percent of the doctors had experienced a complication of dental treatments. About 60 to 80 percent of the doctors accepted the standards of dental treatments for medically compromised patients which we described in the questionnaire, excepting the matters about timing for tooth extraction in the patients with myocardial infarction and the control level of blood sugar.
