Evaluation of the incidence of malocclusions among school-age children in Lublin

Journal Title: Forum Ortodontyczne - Year 2017, Vol 13, Issue 3

Abstract

The evaluation of the incidence of malocclusions is the first step to assess the demand for orthodontic treatment in a given population, to plan prophylactic activities, to set priorities for early treatment, and to determine the efficacy and effectiveness of therapeutic activities to be introduced. Aim. To assess malocclusions in primary school students at the age of 10–12 years in Lublin. The epidemiological study was aimed to assess the presence of dental abnormalities, but without complete specialised orthodontic diagnostics. Material and methods. The study group included 242 children at the age of 10–12 years, namely 118 girls and 124 boys who were students at randomly selected primary schools in Lublin. A clinical examination of the masticatory organ was conducted in school dental offices. Results. Normal occlusion was observed in 15.3% of children in the study group. Malocclusions ranging from mild to severe were observed in 84.7% of subjects. Class I malocclusion was diagnosed in 57% of the study group, class II – in 24.3%, and class III – in 3.3%. In a group of 10–12-year-old children the most common orthodontic abnormality included increased overbite that was observed in 52.1% of subjects, followed by crowding of lower incisors diagnosed in 45.9% of subjects. Conclusions. Among 10-12-year-old students of Lublin schools malocclusions were observed in the significant majority of children. Class I and class II malocclusions were predominant therapeutic needs in a group of 10-12-year-old children according to studies conducted. With regard to class I malocclusions the most frequently diagnosed abnormalities requiring orthodontic treatment included: increased overbite, crowding of lower incisors and transverse abnormalities.
