Nav. Med. Serv. FD BMJ Publishing Group Ltd SP 85 OP 91 DO 10.1136/jrnms-75-85 VO 75 IS 2 A1 Alexander, D. C. C. A1 Pethybridge, R. J. YR 1989 UL http://jrnms.bmj.com/content/75/2/85.abstract AB The 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.
