ETIOLOGY AND PREVALENCE OF MALOCCLUSION IN THE KINGDOM OF SAUDI ARABIA - A CROSS SECTIONAL QUESTIONNAIRE STUDY

Objective:We attempted toassess the prevalence of malocclusion, in terms of age and gender in the Kingdom of Saudi Arabia. We also attempted to identify the predominant risk factors for malocclusion and consequences of the same. Methods:A cross-sectional questionnaire study was conducted. Patients were questioned on heredity, childhood adverse oral habits and feeding habits. Questions pertaining to dental history and current oral health were also asked. Recorded data was analysed using SPSS version 17. Results:Malocclusion was more prevalent in males and below 20 years of age. Tongue thrusting increased the risk of malocclusion by 59%, bottle feeding by 18%, while heredity increased malocclusion risk by 98%. Malocclusion increased the chances of developing dental caries or periodontal disease by 26%, while the risk of dental or facial trauma was increased by 86%. Conclusion: Heredity and tongue thrust habit are the most significant risk factors for malocclusion. Patients with malocclusion are at high risk of developing dental or facial trauma, and are at slight risk of developing caries or periodontal problems.
