Objective To investigate the prevalence of oral diseases in the Armed Policed Forces in Tibet, and to provide ba- sis for preventing dental diseases of them. Methods According to the 3rd national oral diseases epidemiological survey and Oral Health Survey of WHO, 1520 military persons in Lhasa were recruited by the cluster sampling method. They were divided into 4 groups according to length of military service. All the samples were asked to fill in a questionnaire and examined. Results There was no sig- nificant difference between the new recruit group and the 1-4 year service group, 5-9 year service group, ≥10 year service group in o-ral health behavior. Significant differences were found between the new recruit group and the 1-4 year service group, 5-9 year service group, ≥ 10 year service group in relevance ratio of caries, gingivitis, periodoutitis and actinic cheilitis （P 〈0.05 ）. As the length of military service increased, the detection rate was improving statistically. Conclusions With the increase of garrison durations, the de-tection rate of oral diseases in Armed Policed Forces in Tibet is elevated statistically. Therefore, oral hygiene instruction should be strengthened for them. Oral health supporting conditions should be improved along with timely prevention and treatment of oral disea-ses.
