Changing trends in Dental Restorative Treatment needs of Naval recruits 1987–1989—Disease or Diagnosis?
Keyword(s):
AbstractThe restorative treatment needs of 9960 young men and women who entered the Naval Service at HMS Raleigh between January 1987 and April 1989 are summarised. A marked increase in the numbers of fillings required and a decrease in the proportion considered to be dentally fit occurred in May 1988 and has continued as a trend thereafter. Weighted non-orthogonal analysis of variances have been conducted to assess the significance of clinical and period variables upon the changes.
