Abstract
BACKGROUND: Due to the aging of the population on one hand and both medical and dental innovations on the other, the number of medical complications which occur during dental treatment is expected to rise. In order to prevent such complications, dental practitioners have used a medical risk-related history which includes risk determination and preventive measures (together the MRRH system). In this study, the medical complications which occurred in their practice have been compared with those recorded by a control group. METHODS: First, a tested registration form was used. In addition, the group using the MRRH system had previously attended a 1-day introductory course de voted to the MRRH system. Furthermore, a power analysis was used to determine the group sizes. The registration period was set at 1 year, during which the dentists sent in monthly reports. Only patients over the age of 18 were included, after having given their oral consent. An independent diagnosis was given of all registered medical complications by two different internists. RESULTS: A total of 208 medical complications were reported: 45 complications were reported by the 62 dentists who used the MRRH system (reference group) and 163 by the 215 dentists of the control group. First, it should be noted that some reports did not register vital signs; this is reflected in categories such as "no diagnosis," "collapse eci," and "others." Second, the study has revealed that the reference group has registered the heart rate and the frequency of breathing of patients more frequently than the control group. Also, a relatively lower percentage of complications was recorded within the reference group due to the intravenous injection of local anesthetics. CONCLUSIONS: The number of medical complications recorded in the two groups shows little variation. There is a considerable difference, however, in the nature of these complications.
