Abstract

Background and Aims: The aims of this article were to examine the reliability of regression equations suggested for Turkish population and develop new equations to increase the predictive accuracy. Materials and Methods: Crown widths were measured on dental casts of 198 patients. Correlation coefficients were determined to evaluate the two prediction methods suggested for Turkish population. Pearson correlation coefficient was used to determine which sum of permanent tooth widths has the best predictive ability. New regression equations were calculated Results: There were statistically significant differences between genders and arches ( P < .05) in the widths of teeth. Sum of permanent upper first molar, lower central and lateral incisors had the highest correlation. The linear regression equations were determined to be: Y= 5.243 – 0.249(X0) + 0.386(X1) for the maxilla, and Y= 5.008 – 0.227(X0) + 0.378(X1) for the mandible, where Y was the sum of the unerupted permanent canine and premolar widths, X0 indicates gender, and X1 was the sum of permanent upper first molar, lower central and lateral incisors. Conclusion: The new regression equations developed in this study can be used for an accurate mixed dentition analysis in the orthodontic treatment planning of Turkish children.

Özet

Amaç: Amaçlarımız Türk popülasyonu için önerilmiş regresyon denklemlerinin güvenilirliğini değerlendirmek ve tahmin doğruluğunu arttırmak için yeni denklemler geliştirmekti. Materyal ve Metod: 198 hastanın modelleri üzerinde dişlerin kron genişlikleri ölçüldü. Türk popülasyonu için önerilen iki tahmin metodunun güvenilirliğini değerlendirmek için korelasyon katsayıları belirlendi. Hangi daimi dişlerin tahmin kesinliğinin en yüksek olduğunu belirlemek için Pearson korelasyon katsayısı kullanıldı. Yeni regresyon denklemleri hesaplandı. Bulgular: Diş genişliklerinde cinsiyetler ve dental arklar arasında istatistiksel olarak anlamlı farklar vardı ( P<.05). Daimi üst birinci molar, alt santral ve lateral keserlerin diş boyut genişlikleri toplamı en yüksek korelasyona sahipti. Lineer regresyon denklemleri şu şekilde bulundu: Maksilla için Y= 5.243 – 0.249(X0) + 0.386(X1) ve mandibula için Y= 5.008 – 0.227(X0) + 0.378(X1). Bu denklemlerde Y sürmemiş daimi kanin ve premolar genişliklerini, X0 cinsiyeti ve X1 daimi üst birinci molar, alt santral ve lateral keserlerin diş boyut toplamını göstermektedir. Sonuç: Bu çalışmada hesaplanan yeni regresyon denklemleri Türk çocuklarının ortodontik tedavi planlamasında doğru bir karma dentisyon analizi için kullanılabilir.
