ICON To Evaluate The Orthodontic Need And Difficulty Of Stomatological Undergraduates In Xinjiang

Objective:Application of the Index of orthodontic treatment Complexity,Outcome and Need(ICON)to evaluation of xinjiang medical university orthodontic treatment need and difficulty of stomatological students,provide scientific basis for prevention and control.Methods:Using cluster sampling method,a total of 619 stomatological undergraduates,265 males and 354 females;Han nationality were 376,Uyghur 202 and other ethnic minorities 41;aged from 21 to 26 years were enrolled in this study.For marking plaster model,application ICON to determine the orthodontic treatment need and difficulty.Results:The results are expressed by M(P25,P75).Male ICON scores were 23(14,34.5),female scores were 21(14,33),they were no significant differences in sexes(P> 0.05).ICON scores of Han nationality were 21(14,33),Uyghur 23(14,33)and other ethnic minorities 26(19.5,34).There was no significant difference in ICON scores among ethnic groups(P> 0.05).According to ICON score,orthodontic treatment requirements: the need for orthodontic treatment of men were 34 cases(12.8%),women need to treat 29 cases(8.2%),they were no significant differences in sexes(P> 0.05).Among the inter-ethnic groups,42 cases(11.2%)needed orthodontic treatment,18 cases(8.9%)were Uyghur and the other 3 cases(7.3%),There was no significant difference among ethnic groups(P> 0.05).Orthodontic treatment difficulty: "easy" accounted for 66.6%,"easier" accounted for 28.3%,"moderate difficulty" accounted for 3.2%,"difficult" 2.4%,"very difficult" 1%.There was no significant difference among sexes and ethnic groups(P> 0.05).Conclusion:1.The stomatological undergraduates have less need and difficulty for orthodontic treatment in Xinjiang Medical University,the prevention and publicity of dental diseases in Xinjiang is effective.2.ICON is a credible,repeatable,comprehensive malocclusal epidemiology index,which is conducive to determine the need,difficulty,the results of orthodontic improvement,and recommends the use of orthodontic.
