title: Comparison of oral-health-related quality of life during treatment with headgear and functional appliances.
abstract: BACKGROUND
  Functional and headgear are two well-known approaches in the treatment of skeletal class II malocclusion in preadolescent children. Assessment of psycho-social impacts of wearing devices during the treatment period is central to enhancing the quality of healthcare services.
  
  
  OBJECTIVE
  This study aimed to compare oral-health-related quality of life in two groups consisting of children wearing headgear or functional appliances. We also compared these groups with a non-malocclusion group.
  
  
  METHODS
  The study population consisted of 187, 11- to 14-year-old children in three groups of functional (n = 67), headgear (n = 67) and non-malocclusion (n = 53). Children were asked to complete the translated version of the short form of the Child Perceptions Questionnaire. Total scores and subscale scores of the three clinical groups were compared through ANOVA.
  
  
  RESULTS
  There was no significant difference in mean total scale score and subscale scores between functional and headgear groups (P > 0.05). Significant differences were found in both mean total and subscale scores between the malocclusion and non-malocclusion groups (P < 0.001) except oral symptoms subscale (P > 0.05).
  
  
  CONCLUSIONS
  The results of this study reveal that functional and headgear appliances do not differ in terms of impact on daily life during the treatment. Moreover, both groups have poorer OHQoL compared to malocclusion group.
