The dental histories of 100 long-term members of the Royal Australian
Air Force were obtained from their dental records. Data relating to de
ntal health status, as measured by the DMF indices and the T-Health sc
ores, were tested to determine if there were any correlations present
between changes in dental health and certain risk factors which had be
en identified by previous studies in the General Dental Service in Sco
tland. These studies had demonstrated positive relationships between t
he frequency of dental examination and the frequency with which patien
ts changed their dentist, with the amount of dental treatment the pati
ents received. However, within the potential limitations imposed by th
e sample size, the present long-term study did not detect any signific
ant associations between the frequencies of dental examination or chan
ge of dentist, with changes in dental health.
