Objectives: (1) To assess the effectiveness of the Orthognathic Quality of Life Questionnaire (OQLQ) and the Child Oral Health Impact Profile (COHIP) to detect differences in Oral Health-Related Quality of Life (OHRQoL) between pediatric patients with dentofacial deformities and controls. (2) To assess for correlations between scores from the OQLQ and COHIP domains with the type and severity of the skeletal mal-relationship. (3) To assess if the COHIP and OQLQ were identifying unique or overlapping OHRQoL concerns.
Materials and methods: Subjects were under age 18, presented with a dentofacial deformity, and completed both surveys. Matched controls completed the same. Severity for conditions was recorded via overjet, overbite, and ANB values and subjects were classified as skeletal Class I, II, or III.
Results: Enrollment yielded 30 subjects and 31 controls. For the OQLQ, significant differences between subjects and controls were found for the Facial Esthetics domain, Oral Function domain, and total score. For the COHIP, significant differences were found for the Social/Emotional Well-Being and Self-Image domains plus total score. There were no significant correlations between the severity of the condition as measured by overjet and reported OHRQoL for any domains.
Conclusions: The OQLQ and COHIP are effective at detecting significant OHRQoL differences between pediatric patients with dentofacial deformities and controls. Although there is some overlap in the results, the instruments appear to identify different OHRQoL concerns.
