Association of orthodontic treatment needs and oral health-related quality of life in Saudi children seeking orthodontic treatment

INTRODUCTION The objective was to assess the effects of different orthodontic treatment needs on the oral health-related quality of life (OHRQoL) of Saudi children seeking orthodontic treatment as perceived by the children and their parents. METHODS A cross-sectional evaluation of orthodontic patients and their attending parents was conducted to assess the relationship between orthodontic treatment needs and the OHRQoL. The study sample comprised 120 young orthodontic patients (36 boys, 84 girls; age range, 12-15 years). Each participant was assessed for orthodontic treatment needs and OHRQoL using the Dental Health Component of the Index of Orthodontic Treatment Needs and the Michigan Oral Health-related Quality of Life Scales-Version C (child) and Version PG (parent/guardian), respectively. RESULTS Orthodontic treatment needs significantly affected mouth aching, chewing and biting, going to school, and playing. Higher income and borderline index of orthodontic treatment needs are significantly related to oral health impact on quality of life perceived by the child, while younger age and high school education are related to oral health impact on quality of life as perceived by the parent/guardians. CONCLUSION These findings emphasize the impact of malocclusion on OHRQoL in children.
