Abstract

The aim of this study was to determine the prevalence of tooth size discrepancy and average Bolton tooth size ratios in a group of orthodontic patients with skeletally Class I jaw relationship and normal vertical growth. A total of 850 cases were examined and according to selection criteria and 3 study groups were formed as 48 Angle Class I, 60 Angle Class II and 44 Angle Class III subjects resulting in a final sample of 152 subjects. The material comprised the standardized lateral cephafograms and dental casts obtained from the individuals before the treatment. Analysis of variance was performed to compare the mean ratios of Bolton analysis as a function of Angle classification and gender. In order to determine the prevalence of tooth size imbalances among the three malocclusion and the two gender groups, chi-square tests were performed. No statistically significant differences were determined for the mean values of Bolton's anterior and overall ratios among the groups and genders. No statistically significant differences were observed in Bolton's anterior and overall tooth size prevalence among the malocclusion groups and between the two genders. However, the prevalence of Bolton's anterior and overall tooth size discrepancies was found very high in our sample. The presence of high prevalence of tooth size discrepancies in an orthodontic patient population suggested that the measurement of inter-arch tooth size ratios before the treatment might be clinically beneficial for treatment outcome and future expectations.

Özet

Çalışmamızın amacı normal vertikal gelişim gösteren, iskeletsel Sınıf I çeneler arası ilişkiye sahip bir grup ortodonti hastasında Bolton oranları ve diş boyutu uyumsuzluğu prevelansının belirlenmesidir. 850 hasta incelenerek, seçim kriterlerine uyan 48 SınıfI , 60 Sınıf II, 44 Sınıf III malokluzyona sahip toplam 152 hasta çalışmaya dahil edilmiştir. Çalışma materyali bireylerden standart koşullarda elde edilmiş sefalometrik tümler ve ortodontik modellerden oluşmaktadır. Varyans analiziyle, 3 grup hasta arasında cinsiyet ve Angle sınıflamasının bir fonksiyonu olarak ortalama Bolton oranlarının karşılaştırılması yapılmıştır. Bu 3 grup arasında Bolton düzensizliğine bağlı dağılımlar kikare testleriyle değerlendirilmiştir. Bolton oranlarına ait ortalamalar gruplar ve cinsiyetler açısından yapılan değerlendirmelerde önemli farklılık göstermemiştir. Bolton anterior ve genel oranlarına bağlı dağılım incelemelerinde de cinsiyet ve gruplar açısından önemli dağılım farklılıkları bulunmamıştır. Bununla birlikte Bolton anterior ve genel oranlarına ilişkin uyumsuzluklar örnek grubumuzda oldukça yüksek oranda bulunmuştur. Sonuç olarak bir ortodontik hasta grubunda Bolton uyumsuzluğunun yüksek oranda saptanmış olması bu ölçümlerin tedavi öncesinde uygulanmasının tedavi sonuçları ve gelecek klinik beklentiler için faydalı olduğunu düşündürmektedir.
