Impact of malocclusion on Oral Health-Related Quality of Life (OHRQoL) using the Oral Health Impact Profile (OHIP-14)

Abstract

Aim: The present study aims to examine the oral health-related quality of life (OHRQoL) using the Oral Health Impact Profile (OHIP-14) among patients with orthodontic complaints in terms of malocclusion classification from the aspects of gender and age. Methods: The present study was carried out using face-to-face interviews with 150 patients (73 females and 77 males) aged between 12 and 34 years. Demographic information, including age and gender, was requested from the patients via the questionnaire form. Participants were requested to complete the abbreviated version of the OHIP-14 to assess the OHRQoL. Patients were classified into three groups: Class I (n = 50), II (n = 65), and III (n = 35) by Angle classification. In order to measure the OHRQoL, the patients were asked to answer the Turkish version of the Oral Health Impact Profile (OHIP-14). The statistical analyses were performed using ANOVA, Bonferroni, and the Student’s t-test. The statistical significance level was set at p < 0.05. Results: In OHRQoL, the Class III group was found to have statistically significantly higher values when compared to the Class II and Class I groups (p < 0.05). The mean scores in the psychological discomfort and handicap subscales were found to be statistically significantly higher (p < 0.05). Conclusion: Malocclusion has a negative effect on OHRQoL. The increasing severity of malocclusion causes lower OHRQoL. How to cite this article: Topal R.
