CUETO, Alfredo et al. Prevalence of Dentomaxillary Anomalies and Treatment Needs in Adolescents. Int. J. Odontostomat. [online]. 2017, vol.11, n.3, pp.333-338. ISSN 0718-381X.

Dentomaxillary anomalies are a public health problem in Chile, resulting in the need for screening and prioritization of treatment. Dentomaxillary anomalies affecting the aesthetics can be a barrier to social integration of adolescents. The Dental Aesthetic Index (DAI) is an instrument to prioritize the need for treatment of malocclusions. The purpose of this research was to characterize the malocclusions, orthodontic treatment needs and esthetic self-perception in schoolchildren from 12 to 15 years through DAI. Prevalence Study in 12 to 15 year-old adolescents from Viña del Mar. The exclusion criteria was previous orthodontic treatment. The sample was 204 subjects selected by uniform allocation with a confidence level of 95 %. Variables included age, type of educational establishment, sex, aesthetic perception and DAI by component. Prevalence of dentomaxillary anomalies by DAI was 63 % [56 % - 70 %], Treatment needs were 44.2 % treatment elective, 31.01 % highly desirable and 24.81 % mandatory. The Community’s DAI was 29.5. The relationship between DAI and aesthetic perception was significant (p-value: 0.006; Rho: 0.343). The prevalence of dento-maxillary anomalies measured by DAI reaches 63 % and the communal DAI was 29.54 stating that the group "requires elective treatment for definite malocclusion"; in private schools, it is underestimated because some cases had already been treated prior to this investigation.
