Histologic Response of Bone to Sectioning by High-Speed Rotary Instruments

Abstract

SYNOPSIS IN INTERLINGUA RESPONSA HISTOLOGIC DE OSSO AL SECTION AGE PER INSTRUMENTOS ROTATORI DE ALTE VELOCITATE.—Con le utilisation de fluorescentia inducite per tetracyclina, le guarition de defectos ossee in crestas mandibulo- e maxillo-alveolari, in le margine inferior del mandibula, e in le femores de canes esseva studiate comparativemente post le production del defectos per fresas in rotation a velocitates de 200.000 rpm e, in le mesme animales, post lor production per fresas in rotation a velocitates de 5.000 rpm. Le marcage con tetracyclina revelava osso nove in omne le defectos 14 dies post le operation. Quaranta-duo dies post le operation nulle differentias quantitative o qualitative esseva observabile in le natura del responsa reparatori inter le defectos effectuate a basse e a alte rapiditates.
