METHODOLOGY: This cross-sectional study involved 222 subjects (50% DS, 50% NS) who were matched by gender and age. The casts were digitized into three-dimensional images. These images were used alongside the ten occlusal characteristics of the Dental Aesthetic Index (DAI) to determine malocclusion severity and the need for orthodontic treatment.
RESULTS: There were 58 (52.3%) females and 53 (47.7%) males with a mean age of 18.4 ± 8.4 years in both groups. The most common and significant (p 30). The DS showed some impact of malocclusion traits components of the DAI.
CONCLUSION: The occurrence of malocclusion was higher in DS, implying a higher need for orthodontic treatments than for NS subjects.
