FARKLI SAGİTTAL İSKELETSEL İLİŞKİYE SAHİP PEDİATRİK ORTODONTİK BİREYLERDE FRONTAL SİNÜS BOYUTLARININ İNCELENMESİ≠

Amac : Bu calismanin amaci; farkli sagittal iskeletsel iliskiye sahip bireylerde, frontal sinus morfolojisini postero-anterior sefalometrik radyograflar kullanarak arastirilmasidir. Gerec ve Yontem : 75 bireyden olusan calisma cenelerin sagittal iskeletsel iliskisine gore 3 gruba ayrilmistir (Sinif I bireyler; ortalama yas: 15,14±1,40 yil, Sinif II bireyler; ortalama yas: 15,21±1,77 yil, Sinif III bireyler; ortalama yas: 15,16±1,57 yil). Frontal sinusun sag ve sol maksimum yuksekligi ve genisligi, maksiller genislik, nazal genislik, kranial genislik ve antegonial genislik parametreleri 75 postero-anterior sefalometrik radyograf uzerinde olculmustur. Veriler bagimsiz t, Mann Whitney U, tek yonlu varyans analizi ve Kruskal-Wallis testleri kullanilarak analiz edilmistir. Bulgular : Sag frontal sinus yuksekligi, sol frontal sinus yuksekligi ve genisligi gruplar arasinda istatistiksel olarak anlamli farklilik gostermistir ( P <0.05). Ayrica, Sinif III bireylerde sag frontal sinus genisligi erkeklerde kadinlardan daha genis bulunmustur ve bu fark istatistiksel olarak anlamlidir ( P <0.05). Sonuc : Frontal sinus boyut parametreleri farkli sagittal iskeletsel cene iliskisine sahip bireylerde farklilik gosterebildiginden adli dis hekimligine farkli bir bakis acisi getirebilecektir.

Materials and Methods: The study sample consisted of 75 subjects divided into three according to their jaw sagittal skeletal relationship groups (Class I subjects; mean age: 15.14±1.40 years, Class II subjects; mean age: 15.21±1.77 years, Class III subjects; mean age: 15.16±1.57 years). The right and left maximum height and width of the frontal sinus, maxillary width, nasal width, cranial width, antegonial width parameters were measured in 75 postero-anterior cephalometric radiographs. The data were analyzed using independent t, Mann Whitney U, one-way analysis of variance and Kruskal-Wallis tests. Results: Right frontal sinus height, left frontal sinus height and width show statistically significant differences among groups ( P <0.05). Moreover, right frontal sinus width was larger in males than females in Class III subjects and this difference was statistically ( P <0.05). Conclusion: The frontal sinus dimension parameters may bring a different perspective to forensic dentistry because they may differ in individuals with different sagittal skeletal jaw relationship .
