title: Malocclusion and crowding in an orthodontically referred Turkish population.
abstract: This study was conducted to evaluate malocclusion and crowding in 1356 patients (793 girls, 563 boys) referred to the Department of Orthodontics, Suleyman Demirel University, Turkey. Class I was the most frequently seen malocclusion in this referred Turkish orthodontic population whereas Class II, division 2 was the least frequently seen. Comparison of mean ages of the malocclusion groups indicated statistically significant difference between Class I and Class II, division 1 groups (P < .05). The lowest mean age was present in the Class II, division 1 group. Mild mandibular crowding was the most common finding whereas severe mandibular crowding was seen least frequently in all malocclusion groups. Cross tabulation of maxillary and mandibular crowding indicated that mild maxillary and severe mandibular crowding in the same patient was rarely seen in all types of malocclusions. Moderate maxillary and severe mandibular crowding in the same patient was another rare finding for all malocclusion groups.
