Resumen

PEDREROS, Valentina; PEIGNA, Gonzalo; GONZALEZ, Luis  y  PEREZ-FLORES, Antonieta. Orthodontic treatment need in 12-year- old adolescents, city of Diego de Almagro, Atacama Region, Chile. Int. j interdiscip. dent. [online]. 2020, vol.13, n.3, pp.127-131. ISSN 2452-5596.  http://dx.doi.org/10.4067/S2452-55882020000300127.

Objective:

To determine the orthodontic treatment need in 12-year-old adolescents from the city of Diego de Almagro, Chile, according to the Dental Aesthetics Index (DAI)

Materials and Methods:

descriptive, observational, cross-sectional and non-probabilistic study. The DAI was applied to 97 12-year-old students belonging to the city of Diego de Almagro, Atacama Region. The sample was of census type. The information was obtained through a standardized clinical examination performed by a previously calibrated researcher, fulfilling the recommendations described by the World Health Organization for this type of studies. The DAI criteria were analyzed descriptively.

Results:

97 out of 118 students met the inclusion criteria, 45 (46.3%) were males and 52 (53.7%) females; 17.52% of the children examined obtained DAI scores ≤ 25, indicating a normal occlusion or minimal malocclusion, which determines that the treatment is unnecessary or not necessary; 16.49% obtained a score between 26 and 30, indicating a manifest malocclusion and an optional treatment need; 16.49% obtained a score between 30 and 35 with severe malocclusion and a treatment need desirable by the patient; 49.48% had a DAI score ≥ 36, indicating a very severe or disabling malocclusion with a compulsory treatment need.

Conclusions:

There is a high mandatory orthodontic treatment need in the 12-year-old adolescent population, based on the fact that 65.97% of the studied sample through DAI presented a severe or very severe malocclusion.
