Authors report on a cohort of Swedish dentists (3585 males, 1150 females) for the period 1961-70. The study shows that suicide rates among dentists are similar to that of the general Swedish population regardless of sex. Male dentists, however, exhibit an almost 2-fold elevation in suicide rates compared to other male academics. Results indicated an elevatedstandardized mortality rate for males when compared to other male academics: female dentists did not exhibit any increased risk. 15 Refs.
