Ratlarda (Wistar Albino) Mandibula'nın Morfometrisi

OZET Bu calisma rat mandibulasinin kemirgen grubunda bulunmasindan kaynaklanan anatomik farkliliklari ortaya koymak ve cinsiyetler arasindaki iliskileri karsilastirmak amaciyla yapildi. Calismada 20 haftalik; 20 disi ve 20 erkek olmak uzere toplam 40 adet Wistar Albino sican kullanildi. Eter anestezisi altinda sakrifiye edildikten sonra maserasyon islemine tabi tutuldu. Elde edilen mandibula'nin uzunluk ve yukseklik olcumleri tespit edilerek istatistiksel degerlendirmeler yapildi. Total mandibula uzunlugu 2 (TMU2) ve mandibular incissiv corona uzunlugu (MICU) olcumlerinde erkek ve disi sicanlar arasinda istatistiki anlamda onem tasiyan farklar tespit edildi (p<0,05).

Total 20 female and 20 male Wistar Albino rats of 20 weeks age were used. Rats were sacrified under ether anaesthesia and macerated. Mandible were recovered, length and height measurements were determined and evaluated statistically. Measurements of the total length of mandible 2 (TMU2) and the length of the mandibular incissiv corona (MICU) had differences between sexes and the difference was statistically significant (p<0,05).
