Abstract
Amaç: Mandibular trabeküler kemiğin fraktal boyut (FB) değerlerinin yaş,
cinsiyet ve ilgi alanı (ROI, Region of Interest) seçimi ile ilişkisinin
araştırılmasıdır.
Gereç ve Yöntemler: Kliniğimize ilk muayene amacı ile başvuran sistemik yönden sağlıklı 106
birey (53 kadın ve 53 erkek) çalışmaya dahil edilmiştir. Bireyler 21-25, 26-30,
31-35, 36-40 olmak üzere dört yaş grubuna ayrılmıştır. Mandibulada kondil,
angulus ve dişli alveolar kemik bölgelerinden belirlenen sağ-sol toplam altışar
ROI üzerinde White ve Rudolph’un yöntemine göre fraktal analiz uygulanmıştır.
İstatistiksel analizler SPSS v21.0 (IBM Corp, Armonk, NY, USA) programı
kullanılarak yapılmıştır. Normal dağılıma uymadığı test edilen veriler için
non-parametrik testler uygulanmış ve p<0.05 düzeyinde anlamlı kabul
edilmiştir.
Bulgular: Cinsiyete göre sağ angulus (p=0.024) ve sol kondil (p=0.009) FB
değerleri arasında istatistiksel olarak anlamlı fark bulunmaktadır. Bireylerin
yaş gruplarına göre sadece sol kondil FB değerleri istatistiksel olarak anlamlı
fark göstermektedir (p=0.000). Çenenin aynı tarafından seçilen kondil, angulus
ve dişli bölgelerin FB değerleri birbirlerinden anlamlı farklılık gösterirken
(p<0.05), sağ-sol FB ölçümlerinde istatistiksel anlamlı fark saptanmamıştır
(p>0.05).
Sonuç: Alt çenede kondil ve angulus bölgesinden seçilen bölgelerde FB
ölçümleri yaş ve cinsiyete göre değişiklik göstermektedir. Yapılacak
çalışmalarda ROI seçerken sağ-sol ayırt etmeksizin mümkün olduğunca dişli
alveolar kemik bölgesi tercih edilmelidir.
