1. The prevalence of malocclusion and orthodontic treatment needs in Al- qudaimi school Aljeraf-sana’a city 2024 Dental assistant Supervised by DR: Mohammed Alsafadi Modern specialized collage for medical & technical sciences

2. Introduction Malocclusion of the teeth is not really a disease in the way that dental caries and periodontitis are, it is more a reflection of the natural variation that occurs in any biological system. Malocclusion or “bad bites” is one of the most common dental problems. When you have malocclusion, your upper and lower teeth don’t align when you close your mouth. Malocclusion typically happens when your teeth are crowded — meaning your teeth are too large for your mouth — or are crooked and it also happen when there are so much spaces between your teeth. Left untreated, malocclusion can cause several health problems. Apart from causing dental problems such as decayed teeth, losing teeth or developing gum disease. The prevalence of malocclusion varies from one region to another and among different ethnic groups, age- groups, and gender groups.
