Abstract
BACKGROUND: This study aimed to evaluate facial photoanthropometric parameters in patients with OI. MATERIAL AND METHODS: We selected 20 Brazilian patients diagnosed with OI treated at the Extension Service for Minors in Need of Specialized Treatment of the Dentistry Course at the Federal University of Ceará (Fortaleza, Brazil), of both sexes, without age restriction, and able to understand and sign the informed consent form (ICF). As a control group, 38 non-syndromic Brazilian individuals, categorized as ASA I, able to understand and sign the ICF, matched by sex, age, and Legan and Burstone facial profile were selected. The exclusion criteria were: previous orthodontic treatment, craniofacial trauma and/or surgery, and the presence of any other systemic diseases. Photoanthropometric analysis of the 18 facial parameters proposed by Stengel-Rutkowski et al. (1984), previously established in the literature for craniofacial syndromes, were conducted. A single examiner digitally performed all effective and angular measurements with the CorelDRAWX7® software. RESULTS: Horizontally shortened ears (p<0.001) but larger in height in relation to the face (p=0.012) were shown to be alterations belonging to individuals with OI. CONCLUSIONS: OI patients present distinct photoanthropometric parameters inherent in this condition.
