Osteotomia com brocas de alta e baixa rotação, com e sem refrigeração líquida: estudo histopatológico duplo cego em suínos

Nine swines of the White Large race were used for study of the process of bony repair after osteotomy with rotating instruments of low and high-speed, with and without liquid refrigeration. The authors observed, through double blind histopathological analysis, that in every analyzed operative time, the bony repair was processed more appropriately when the osteotomies were accomplished with liquid refrigeration. In the final postoperative times, of fourteen and twenty-eight days, the best results of bony repair were observed in the osteotomy accomplished with drills of low rotation and with liquid refrigeration, while in the postoperative time of seven days, the results of the bony repair of osteotomy accomplished with drills of high rotation and with liquid refrigeration they were better. The authors consider, still, that the process of bony repair in swine display larger proximity in the histological pictures among the studied variables, when compared with other biological models. As most of the works told in the literature it refers the use of dogs, the authors consider that the present work guarantees your importance in the sense of looking for a closer model of the man. ; Nueve cerdos Large White fueron utilizados para estudiar el proceso de curación del hueso después de la osteotomía con baja y alta rotación, con y sin refrigeración líquida. Se observó a través de histopatología doble ciego, que en todos los tiempos estudiados la reparación ósea ocurrió más apropiadamente cuando osteotomías se realizaron con refrigeración por líquido. En los postoperatorios de catorce y veintiocho días., se observaron los mejores resultados de reparación en osteotomías realizados con los taladros de baja velocidad y refrigeración por líquido. En el postoperatorio de siete días, los resultados de la curación del hueso en osteotomías realizadas con los taladros de alta velocidad y refrigeración por líquido, fueron ligeramente mejores. Se considera que el proceso de reparación ósea en los cerdos muestra la similitud con ...
