Impact of malocclusion on oral health-related quality of life (OHQoL) using the Oral Health Impact Profile (OHIP-14)

Aim: The present study aims to examine the oral health-related quality of life (OHRQoL) using the Oral Health Impact Profile (OHIP-14) among the 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 (73 females and 77 males) patients aged between 12 and 34 years. 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 negatively affects the OHRQoL. The increasing severity of malocclusion causes lower OHRQoL.   How to cite this article: Topal R.
