The purpose of this study was to evaluate the oral health of Iranian workers in Japan and their general life conditions, 125 Iranian subjects aged 20-43 yr congregating in Yoyogi and Ueno Parks in Tokyo were examined. The mean decayed, missing, and filled teeth (DMFT=7.8) and filled teeth (FT=2.3) scores were lower than the Japanese national average. The mean decayed teeth (DT=3.4) and missing teeth (MT=2.2) scores were higher than the Japanese national average. Calculus was the predominant periodontal problem, and shallow pockets prevailed in persons aged 30-34 yr. 39.7% of the subjects had complaints about their oral health, but only 16.8% desired dental treatment in Japan. Most of the subjects could not undergo dental treatment because of the high cost. Analysis of the results showed poor dental health in this survey group and emphasizes the necessity of improving the (dental) health service programs for foreigners.
