There were statistical significance between the prevalence rate of caries, gingivitis and dental calculus of male and female (x2=101.14, P<0.01,χ2=40.45, P< 0.01,χ2 =78.61, P< 0.01). The prevalence rate of caries in Han was 36.68% and in Tibetan, Mongolian, Uyghur were 58.19%, 51.05%, 50.42% respectively; It was statistically significant (x2=47.783, P=0.000, x2=17.877, P=0.000,χ2=16.309, P=0.000), and caries incidence in Han is less than other three minorities. There was statistical significance (x2=7.311, P<0.01) between the prevalence rates of gingivitis in Uygur (39.08%) and Han (30.30%). The detection rates of dental calculus between Mongolian (36.82%) and Han (45.86%), it was statistically significant (x2=6.795, P<0.01).
