Abstract OBJECTIVES: The objective of this study was to describe the prevalence of malocclusion in a population of Central Anatolian adolescents in relation to gender. METHODS: The sample comprised 2329 teenagers (1125 boys and 1204 girls), aged between 12 and 17 years (mean age: 14.6 yrs). Occlusal anteroposterior relationships were assessed using the Angle classification. Other variables examined were overjet, overbite, crowding, midline diastema, posterior crossbite, and scissors bite. RESULTS: The results showed that about 10.1\% of the subjects had normal occlusions, 34.9\% of the subjects had Class I malocclusions, 40.0\% had Class II Division 1 malocclusions, 4.7\% had Class II Division 2 malocclusions and 10.3\% had Class III malocclusions. Over 53.5\% had normal overbites, and 18.3\%, 14.4\%, 5.6\%, and 8.2\% had increased, reduced, edge-to-edge or anterior open bite values, respectively. Overjet relationship was normal in 58.9\%, increased in 25.1\%, reversed in 10.4\%, and edge-to-edge in 5.6\%. A posterior crossbite registered in 9.5\% and scissors bite in 0.3\%. Anterior crowding was present in 65.2\% of the sample and midline diastema in 7.0\%. No clear gender differences were noted, except for normal overbite (most frequent in girls, P<.001) and increased overbite (most frequent in boys, P<.05). CONCLUSIONS: Class II Division 1 malocclusion is the most prevalent occlusal pattern among the Central Anatolian adolescents and the high values (25.1\% and 18.3\%) of increased overjet and overbite were a reflection of the high prevalence of Class II malocclusion.
