Abstract
:
Objectives: The aim of this study was to assess the prevalence of malocclusion and orthodontic treatment needs in a Saudi sample of Jeddah city. Materials & Methods: A cross-sectional (descriptive) study was performed in 2017 among 3016 subjects (1507 females and 1509 males) selected according to a stratified random sampling design. The inclusion criteria were Saudi students aged between 14 to 18 years with no craniofacial deformities or syndromes and no orthodontic treatment carried out. Malocclusion were assessed by using modified Bjork et. al. system and Angle’s classification and orthodontic treatment needs assessed by using the IOTN (DHC). Descriptive, associations & gender differences were assessed by one-way ANOVA, Chi-square and Fisher exacts tests. Data were analyzed using STATA Version 13.0 (StataCorp, College Station, Texas, USA). Statistical significance was set at P<0.05. Results: Approximately 12% of the participants had normal occlusion, 57% had Class I malocclusion, 17% had Class II malocclusion, and 14% had Class III malocclusion. The highest prevalence of malocclusion traits was for displacement followed by crossbite. The IOTN results revealed slight need for orthodontic treatment in (n=795-26 %), moderate/ borderline in (n=1166-39%), and great need in (n=1055-35%). Class II and III malocclusion, OJ, reverse overjet, scissor bite, open bite, midline discrepancies and crowding were significantly higher in males than females (P<0.05). Conclusion: Overall there was a high prevalence of malocclusion and high orthodontic treatment need. The most common malocclusion was class I and the most common orthodontic treatment need was moderate to border line. Keywords: Malocclusion, Prevalence, IOTN (DHC), KSA
