Resumo
Nove suínos da raça Large White foram utilizados para estudo do processo de reparo ósseo após osteotomia com instrumento rotatório de baixa e alta velocidade, com e sem refrigeração líquida. Os autores observaram, através de análise histopatológica duplo cega, que em todos os tempos operatórios analisados, o reparo ósseo se processou mais adequadamente quando as osteotomias foram realizadas com refrigeração líquida. Nos tempos pós-operatórios finais, de quatorze e vinte e oito dias, os melhores resultados de reparo ósseo foram observados nas osteotomias realizadas com brocas de baixa rotação e com refrigeração líquida, ao passo que no tempo pós-operatório de sete dias, os resultados do reparo ósseo de osteotomias realizadas com brocas de alta rotação e com refrigeração líquida foram discretamente melhores. Os autores consideram, ainda, que o processo de reparo ósseo em suínos mostra maior proximidade nos quadros histológicos entre as variáveis estudadas, quando comparado com outros modelos biológicos. Como a maioria dos trabalhos relatados na literatura se refere a utilização de cães, os autores consideram que o presente trabalho garante sua importância no sentido de se buscar um modelo mais próximo do homem.
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.
