IntroductionOral health-related quality of life (OHRQoL) involves many aspects such as chewing ability, sleeping, social interactions, self-esteem, and satisfaction with life and oral health. The increasing research interest in OHRQoL began only after the shortcomings of previous approaches of treating symptoms only and neglecting the patient's self-perception were revealed.Patients And MethodsThe current study design is a cross-sectional study of patients who attended King Abdulaziz University Dental Hospital (Jeddah, Saudi Arabia) and King Saud University Dental Hospital (Riyadh, Saudi Arabia). After obtaining their verbal consent, young adult and adult patients (mean age 25.19±7.29 years old) with anterior spacing or crowding were recruited to participate in the study. They filled the Arabic short version of the oral-health impact profile-14 questionnaire after a clinical evaluation of the severity of their spacing or crowding. Parameters of spacing/crowding severity assessment were as follows: <4, mild; 4-8, moderate; and >8, severe. Data were analyzed using the chi-square test in SPSS statistical package. The level of significance was set to <0.05.ResultsThe sample size of this study was 308 subjects. Findings indicated a statistically significant (p=0.001) association between anterior spacing malocclusion (ASM) with Q5 "self-consciousness", since 64.2% of patients with ASM reported being self-conscious. Results indicated a statistically significant association between educational level with anterior crowding malocclusion (ACM; p=0.02) and ASM (p=0.01) with Q3 "painful aching". Moreover, findings indicated a statistically significant association (p=0.04) between income and ACM with Q5 "self-consciousness". On the other hand, results showed no significant association between gender with either ACM or ASM.ConclusionThis study sheds light on how anterior malocclusion (crowding or spacing) impacts OHRQoL negatively, especially heightening self-consciousness about their appearance. These effects should be addressed by the orthodontist during the course of treatment.
