Abstract (2. Language): 
The purpose of this study is to provide information on the normal growth and development of the dental arches. Materials were longitudinal dental casts obtained from 30 (15 males, 15 females) children wtth acceptable occlusion. The dental casts were taken first at the earty mixed dentttion and then five years later for the purpose of assessment of dental arch changes. Six transversal, one vertical and five sagtttal measurements were made to evaluate changes in the dental arches that occurred in transition from mixed dentition to permanent dentttion. The Student's t test was used to determine if there were any differences between the measurements with regard to sex. First and second set of dental cast measurements were evaluated wtth a parred t test to determine the changes that occurred with growth The results of the Student's t test showed that there was no significant difference between males and females in the majority of the parameters. The results of paired t test showed that in the combined group, significant changes occurred both in maxiila and mandible wtth growth. It was determined that there were statistically significant changes in all the measurements except for total arch length in maxilla but the changes in distances between incisors and between canines in mandible were not significant while the changes in the other measurements were of statistical significance. The results of this study showed that changes in the dental arches that occurred in transition from mixed dentition to permanent dentttion should be well considered in order to obtain acceptable outcomes from orthodontic treatment

Bu çalışmanın amacı diş kavsinin normal büyüme ve gelişimi hakkında bilgi sağlamaktır. Bu çalışmanın materyaiini kabul edilebilir oklüzyona sahip 30 çocuğun longitudinal ortodontik modelleri oluşturmaktadır. Diş kavsindek değişiklikler hakkında bilgi elde etmek için, ortodontik modeller erken karışık dşşlenme döneminde ve beş yıl sonrasında a/ınmıştır. Karışık dişlenmeden daimi dişlenmeye geçişte diş kavsinde meydana gelen değişiklikleri değerlendirmek için 6 transversal, 5 sagtttal ve 1 vertikal ölçüm yapılmıştır. Cinsiyete göre ölçümler arasında farklık olup olmadığını değerlendirmek için Student's t testi kullanılmıştır. Büyüme ile meydana gelen deşikikleri değerlendirmek için eşleştirilmiş t testi kul/anılmıştır. Student's t testi sonuçları ölçümlerin çoğunda cnnstyet farkhıığı olmadığını göstermiştir. Eşleştirilmiş t testi sonuçları bir/eşik grupta maksilla ve mandibulada büyüme ile önemi değişikliklerin meydana geldiğini göstermiştir. Maksiilada total ark uzunluğu dışında diğer ölçümlerde istatiksel olarak önemli değişikliklerin olduğu; mandibulada ise keserler ve kaninler arası mesafe/erdeki değişikliklerin önemli olmadığı ve diğer ölçümlerdeki değişikliklerin istatiksel olarak önemli olduğu tespit edilmiştir. Bu çalışmanın sonuçları, ortodontik tedaviden iyi brr sonuç elde edebilmek için karışık dişlenmeden daimi dişlenmeye geçişte diş kavsinde meydana gelen değişikliklerin iyi binmesi gerektiğini göstermiştir.
