Abstract Background. The epidemiology of the population living in a country plays an important role in the planning and implementation of dental services. Correct identification of the need for orthodontic treatment in individuals is a very complex subject and requires detailed analysis. The aim of this study was to measure the prevalence of malocclusion among randomly selected subjects aged 12-15 years attending secondary schools regardless of any socio-economic or social status in Northern Cyprus.Methods. After the approval of the competent authorities in the Ministry of National Education and the Ministry of Health of Northern Cyprus and of the parents whose subjects were to take part in the study, the evaluation was carried out by a team of three people, two of whom are in the process of specializing in orthodontics and one doctoral student at the qualification stage. The study included a randomly selected sampling composed of 426 subjects (203 females and 223 males). Results. The statistical evaluation of the samples collected in the study found that 20.6% of the subjects had no occurrence of occlusion, 74.4% had Class I, 21.1% had Class II (part 1, 18.8%, part 2, 2.3%) and 4.5% had Class III malocclusion. Of the 419 patients, 86 (20.2%) were in need of orthodontic treatment. Although not statistically significant, it was determined that 19.7% of female patients and 20.7% of the male patients were in need for orthodontic treatment.Conclusions. The most common orthodontic malocclusion in Cyprus is Class I, the least common malocclusion is Class II division 2.
