| الوصف: | Cilj istraživanja: Cilj istraživanja bio je mjeriti i analizirati vertikalnu silu i okretni moment tijekom kemomehaničke obrade korijenskog kanala kod ručne i strojne ProTaper, ProFile, step-back i Endo-Eze tehnike do promjera otvora 0,25mm, te analizirati utjecaj dobivenog opterećenja na nastanak vertikalne frakture korijena (VFK). Analizirano je i vrijeme instrumentacije. Materijal i metode: Istraživanje je provedeno na 100 izvađenih jednokorijenskih ljudskih zubi s ravnim kanalom. Podijeljeni su u 5 grupa, 20 u svakoj. Mjerenje verikalne sile, okretnog momenta i vremena instrumentacije učinjeno je uređajem koji je konstruiran za potrebe ovog rada. Rezultati su izraženi kao medijan, maksimalna i minimalna vrijednost, a statistička značajnost između pojedinih instrumenata i grupa testirana je Mann-Whitney U–testom za P Objectives: The purpose was to measure and analyze the vertical force and torque developed in the root canal systems during mechanical preparation using rotary and hand ProTaper, ProFile, step-back and Endo-Eze instrumentation technique. The influence of the vertical force and torque to orginate vertical root fractures was also analysed. Preparation time was also mesured and analysed. Material and Methods: One hindered extracted human teeth with straight canals were divided in five groups, twenty in each. The root canals are prepared using different hand and rotary instruments. Measurements of the force and torque were done by a device constructed for this purpose. Differences between the groups were statistically analyzed by Mann-Whitney U–test with the significance level set to P |
