title: Photogrammetric analysis of facial profile in Persian adults.
abstract: When facial photographs are analyzed for the purpose of identifying esthetics norms, differences in dentofacial relationships among ethnic and racial groups must be taken into consideration. Therefore, it is necessary to establish standards for various populations. The purpose of this study was to establish norms of photogrammetric soft tissue profile analysis for Persian adults. Pretreatment lateral photographs of 147 subjects (66 men and 81 women aged 18-35 years) with a Class I skeletal pattern were collected. Twelve angular parameters were evaluated in the subjects. Values for men and women were compared with a t test. Statistically significant sexual dimorphism was found for nasofrontal (P < 0.059), nasal (P < 0.059), nasal dorsum (P < 0.001), cervicomental (P < 0.001), facial convexity (P < 0.004), and total facial convexity (P < 0.002) angles. The mean values obtained from this study can assist in orthodontic diagnosis and treatment planning for Persian adults.
