From AC,12.5%of children had great need and very great need for orthodontic treatment need,64.4%of children had no need.2.Research two (1) To compare the CPQ scores between the different degrees of malocclusion groups:the CPQ scores were statistically significant differences(P<0.05). In four dimensions:oral symptoms, oral function and emotional aspects of score differences were statistically significant (P<0.05). Social aspects of score differences were no significant differences (P>0.05).(2) To compare the PPQ scores between the different degrees of malocclusion groups:the PPQ scores were statistically significant differences(P<0.05). All four dimensions:oral symptoms, oral function, emotional and social aspects of score differences were statistically significant (P<0.05).(3) To compare the CPQ scores and PPQ scores, the CPQ and PPQ had significant correlation. Also this correlation was showed in four dimensions:oral symptoms, oral function, emotional and social aspects.(4) To compare the FIS scores between the different degrees of malocclusion groups:the FIS scores were statistically significant differences(.P<0.05). In four dimensions:Parental activity, parental emotions and family conflict of score differences were statistically significant (P<0.05). The scores in financial burden were no significant differences (P>0.05).Conclusion:1.Research one:32.9%of children had great need and very great need for orthodontic treatment need.AC is lesser than DHC.2.Research two:(1) This study indicates that malocclusion affects child’s quality of life from oral symptoms, oral function and emotional aspects.(2) This study indicates that malocclusion has the impact on family life from parental activity, parental emotions and family conflict.(3) The CPQ and PPQ had significant correlation.
