ORTODONTİK MALOKLUZYONLARIN ORTA ANADOLU BÖLGESİNDE YAŞAYAN BİREYLERDEKİ PREVELANSLARININ VE KARAKTERİSTİKLERİNİN İNCELENMESİ

Abstract

Bu çalışmanın amacı, ortodontik tedavi talep eden hastalarda, ortodontik malokluzyonların dağılımlarının incelenmesi ve farklı tip malokluzyonlardaki dişsel ve iskeletsel faktörlerin tanımlayıcı özelliklerinin cinsiyetler arasında ve genel olarak değerlendirilmesidir. Çalışmamıza ortodontik tedavi öncesi teşhis kayıtları değerlendirilen 495 iskeletsel Sınıf I (ortalama yaş: 16.11 ± 3.1), 379 iskeletsel Sınıf II (ortalama yaş: 16.14 ± 2.84) ve 188 iskeletsel Sınıf III (ortalama yaş: 16.94 ± 3.27) ilişkiye sahip toplam 1062 hasta (yaş aralığı: 12.0 – 39.0 yıl) dahil edilmiştir. Lateralsefalometrik radyografiler üzerinde maksilla ve mandibula arasındaki ilişkinin belirlenmesinde, ANB açısı kullanılmıştır (Sınıf I: ANB° = 0 ° ila 4 °; Sınıf II: ANB °> 4 °; Sınıf III: ANB °<0 °). Toplamda 21 doğrusal, 12 açısal ölçüm gerçekleştirilmiştir. Tüm iskeletsel malokluzyon tiplerinde kadınların efektif maksilla ve mandibula uzunlukları ve alt yüz yükseklikleri anlamlı şekilde daha kısa bulunmuştur. Genel olarak, erkekler ve kadınlar arasında overjet miktarında, istirahat keser görünümünde, alt çene diastemasında ve üst çene çapraşıklığında farklılıklar görülmüştür. İskeletsel malokluzyon görülme sıklığı Sınıf I (%46.6)>Sınıf II (%35.7)>Sınıf III (%17.7)’dir.Ayrıca bu çalışma, Anadolu popülasyonundaki iskeletsel Sınıf I, II ve III malokluzyonlara sahip erkek ve kadın hastaların sefalometrik teşhisi için referans değerlerini ve genel olarak tanımlayıcı bilgileri de sağlamaktadır.

EVALUATION OF PREVALENCE AND CHARACTERISTICS OF ORTHODONTIC MALOCCLUSIONS IN INDIVIDUALS IN CENTRAL ANATOLIA

Abstract

The aim of this study is to examine the distribution of orthodontic malocclusions in patients who require orthodontic treatment and to evaluate the descriptive characteristics of dental and skeletal factors in different types of malocclusions between genders and in general. A total of 1062 patients (age range: 12.0 - 39.0 years) with 495 skeletal Class I (mean age: 16.11 ± 3.21), 379 skeletal Class II(mean age: 16.14 ± 2.84) and 188 skeletal Class III(mean age: 16.94 ± 3.27) relationships, whose diagnosis records were evaluated before orthodontic treatment, were included in our study. The ANB angle was used to determine the relationship between maxilla and mandible on lateral cephalometric radiographs (Class I: ANB ° = 0 ° to 4 °; Class II: ANB °> 4 °; Class III: ANB ° <0 °). In total, 21 linear and 12 angular measurements were performed. The effective maxilla and mandible lengths and lower face heights of women were significantly shorter in all types of skeletal malocclusion. In general, differences were observed between men and women in the amount of overjet, the incisor exposure in relaxed lip posture, the diastema of the mandible and the crowding of the maxilla. The incidence of skeletal malocclusion is Class I (46.6%)>Class II (35.7%)>Class III (17.7%). In addition, this study provides reference values and general descriptive information for the cephalometric diagnosis of men and women patients with skeletal Class I, II and III malocclusions in the Anatolian population.
