A review of existing research & death investigations of dentists known to have committed suicide in the state of Iowa during the period 1968-1980 lead the authors to conclude that suicide rates for dentists are elevated over the age-sex rate of the general population. Rates appear to be higher for those entering the profession (24-44) & those concluding their careers (65+). However, the authors state that accuracy in certifying deaths as suicides & other factors may affect the study’s validity.
