Abstract

Introduction: Oral health includes healthy mouth with healthy tissues, which provides for eating, speaking, and social encounters without active disease, discomfort, and dissatisfaction. The present study evaluated quality of life related to oral and dental health, effect of body and mind on oral health, and effect of oral and dental disabilities on daily life of 8-10 year-old children in Isfahan. Materials and Methods: In this descriptive, analytical, and cross-sectional study 138 children aged 8-10 were randomly selected from elementary schools in Isfahan. Children completed the Children Perception Questionnaire (CPQ). Then they were clinically examined and their DMFT (permanent teeth), dmft (deciduous teeth), MIH (molar-incisor hypoplasia), TDI (dental traumatic injuries) indexes and malocclusion were determined. To evaluate the reliability of CPQ, 70 of these children completed the questionnaire two weeks later without any dental interventions during the period. ANOVA, Spearman’s correlation coefficient, Cronbach's alpha and intra-class correlation coefficient (ICC) were used to determine the relationship between the indexes (α=0.05). Results: The mean score of CPQ was 14.68 with a standard deviation of 10.6, which was higher in girls than in boys. Cronbach's alpha and ICC were 0.86 and 0.82, respectively. Oral health-related quality of life did not exhibit any significant relationship with carious lesions in the deciduous and permanent teeth, molar-incisor hypoplasia, dental traumatic injuries and malocclusion (p value < 0.05).   Conclusion: The Children Perception Questionnaire translated into Persian is valid and reliable for use in 8-10 year-old Persian children and can assess the effect of oral and dental disorders on quality of life.   Key words: Caries, Dental trauma, Hypoplasia, Malocclusion, Oral and dental disease, Psychometric projection, Quality of life.
