Malocclusion can have a negative impact on children's quality of life. Patients with severe malocclusions tend to smile less and look for ways to improve their smile. The mentioned study was conducted in 400 patients aged 3 to 18 years, who applied to the dental clinic for orthodontic treatment regardless of age and gender. The aim of the study was the prevalence of occlusion, dental arches and dental anomalies, most often combined occlusion anomalies, functional disorders, carious and filled teeth and periodontal diseases in the examined patients. According to the results of the research, it was established that the majority of the examined patients were female. Among occlusion anomalies, occlusion class II subclass I was detected with the highest frequency. Almost 11% of the examined had a functional disturbances oral and maxillofacial system. 6% of the examined have an anomaly of the shape of the crown of the teeth. 6.25% of cases have microdontia and 5.5% have macrodontia. 1.17% showed pathological wear and 24.55 enamel hypoplasia. 1% supernumerary tooth, of which 0.75% supernumerary tooth between central incisors, 0.25% supernumerary tooth in other area. Persistent tooth in 3.25% of cases. 5% of retentive teeth are one or several teeth at the same time. 26.75% have one or more dystopian postures. Diastema was detected in 19.75%. Most of the examined patients were female, which is explained by the perception of patients and their parents regarding facial aesthetics in relation to gender. Most of the patients turn to orthodontics in cases of occlusal anomalies that are more aesthetically pronounced and easily perceived by others. In the studied society, oral health and oral care skills are given less importance, as evidenced by high rates of periodontal diseases, caries, and filled teeth. In the mentioned population, it is very important to raise the level of knowledge of the importance of oral health, which is possible by conducting educational events in kindergartens, schools, public gathering places, dental clinics.
