Seafaring: a risk for seamen's oral health?

Information about the oral status and dental health behavior and the working history of 369 Finnish seamen on different types of ships was gathered by means of a questionnaire. A control group of workers on shore was formed for sailors 35-44 years of age. Removable dentures were worn by 16% of the seamen. Oral disorders during the week before the study were reported by one-third. During the previous 2 years 14% of the sailors had had at least one episode of oral troubles, 15% twice and 9% three or even more times. One-third of seamen with oral trouble had needed pain-killing tablets or antibiotics. Sick leave days had been needed by 3% of respondents during the previous 2 years because of oral disorder (mean length of sick leave period was 1.4 days). The control group reported gum bleeding more often than the seafarers. Even though there were no signs of poorer dental condition in sailors than in the controls on shore, the possibility that the seafaring could constitute a risk for the oral health of seamen in other age groups cannot be excluded.
