Author: Awad, Razan A.; Abuaffan, Amal H.
Abstract: Objective: The aim of this study was to assess the prevalence of malocclusion in a sample of Sudanese medical students, using the index of orthodontic treatment need (IOTN). Materials and Methods: Digital photographs of 97 university students (43 males and 54 females) which include a lateral and anterior view, using the DHC and AC charts to analyze each photograph. Results: AC Grade 2 being the most common grade 36 (37.1%); grades 6, 7, 9 and 10 had no students that fall under their category. DHC Grade 2 being the most common grade which was 38 (39.2%); whilst the least common grade was Grade 5 which was 1 (1%). DHC Grade 2 is the highest number of students for both genders being 22 for females and 16 for the males. The least common is Grade 5 which had no females but only one male. AC Grade 2 is the most common grade for both sexes being 21 for females and 15 for males. The least common is Grade 6, 7, 9 and 10 had no students fall under their categories. Based on aesthetically impaction, one male student falls under the grade 8 AC category. Based on present or potential dental health and functional indications, 16 students fall under the grade 4 and 5 category in DHC. From these 16 students 8 females and 7 males are a grade 4 DHC, whilst one male and no females fall under the grade 5 DHC categories. Conclusions: One male student falls under the grade 8 AC category, in a great need of orthodontic treatment. 16 students fall under the grade 4 and 5 category in DHC. There’s one male and no females that fall under the grade 5 DHC category. Therefore they are eligible for orthodontic treatment. Students that are either Grade 2 AC or DHC do not need orthodontic treatment.
