Abstract: | OBJECTIVE: To evaluate the prevalence of malocclusion and orthodontic treatment need among Spanish adolescents and compare with other populations. METHODS: The study sample comprised 744 schoolchildren from urban and rural populations in Granada province (Southern Spain), aged from 14-20 years, who had received no orthodontic treatment. The measurement instrument was the Dental Aesthetic Index (DAI). RESULTS: The mean DAI score of the whole series was 25.6 (SD, 7.94). The distribution of the four DAI grades was: DAI 1, no anomaly or malocclusion, 58.6%; DAI 2, definite malocclusion, 20.3%; DAI 3, severe malocclusion, 11.2%; DAI 4, very severe or disabling malocclusion, 9.9%. There were no statistically significant differences in DAI score between genders or those in rural vs. urban residence, but a significant difference was found between social classes, with subjects of low social class presenting the worst scores (p<0.05). CONCLUSION: The distribution of DAI scores among Spanish adolescents is similar to that reported in other populations. |
