Abstract

The World Health Organization recommends carrying out periodic epidemiological studies in order to provide a basis for the evaluation of the state of health of the population at any given time; in doing so, action strategies can be established for the treatment of different pathologies. The objective of this study is to evaluate the need for orthodontic treatment in adolescents at school aged between 12 and 15 in the Spanish autonomous region known as Comunidad Valenciana (hereafter: Valencian Region). A cross-sectional study was carried out on a sample of 539 12-year-old schoolchildren and 460 15-year-olds, respectively, selected by cluster sampling and representative of the school-aged population of the Valencian Region, using the IOTN-DHC, IOTN-AC, and DAI indices. The need for specific orthodontic treatment according to the IOTN-DHC was 12.6% at 12 years and 7% at 15. For the IOTN-AC and DAI indices, the treatment needs were 4.3% and 0.9% at 12 years and 30.1% and 20.9% at the age of 15. These results were similar to those obtained in the previous study carried out on the same target population. There was no significant association between the need for treatment and gender or social class. We conclude that the need for orthodontic treatment presents values similar to those obtained in 2010.

Keywords: DAI; IOTN; oral health; orthodontic treatment need.
