“…Another advantage of this method is that there is no destruction of the sample 14 (2010) which showed it to be reliable, without destructive sectioning of the specimens or loss of the root material during sectioning. Previous studies showed that CBCT used to evaluate root canals prepared with NiTi rotary instruments provided a nondestructive and reproducible method 12,14,21,22 . Data obtained with this technique enable the identification of morphologic changes associated with different biomechanical preparations including canal deviation, dentin removal and final canal preparation.…”

“…Cone beam computed tomography (CBCT) imaging techniques have been evaluated as noninvasive methods for the analysis of canal geometry and efficiency of shaping techniques. Using this technique it is possible to compare the anatomic structure of root canal before and after instrumentation 1,12 . The present study was set out to determine the changes in root canal anatomy using the ProTaper Universal™, Twisted File™ and M two ™ rotary systems analyzed by CBCT.…”

“…Devido à busca de metodologia superior ao exame radiográfico, utilizou-se neste estudo a tomografia computadorizada que trás como vantagens entre outras: a possibilidade de medida da área apical e a visualização da morfologia interna dos canais radiculares em três planos (PAULA-SILVA et al, 2009;REUBEN et al, 2008), gerando imagens de qualidade superior em comparação aos outros métodos existentes (BERNARDES, et al, 2010;LOIZIDES, et al, 2007).…”

“…O preparo rotatório mecanizado com instrumentos de NiTi foi utilizado baseado em suas inúmeras vantagens salientadas em vários estudos (BERNARDES et al, 2010;ESPOSITO & CUNNINGHAN, 1995;GAMBARINI, et al, 2002;GRANDE, et al, 2007;HULSMANN, et al, 2003;KUNERT, et al, 2010;PETERS, 2004), preparando melhor e em menor tempo, quando comparado com a instrumentação manual (BERNARDES et al, 2010;GUELZOW et al, 2005;PETERS, 2004).…”

“…Este fato foi confirmado na análise da quantidade de dentina remanescente onde se observou, que nos níveis 4 e 5 (tabelas 4 e 5), sua espessura diminuiu significativamente para o lado da voltado para furca. Este resultado também foi observado de acordo com estudos prévios (YUN; KIM, 2003;BERGMANS et al, 2003;BERNARDES et al, 2010) Quando avaliou-se a quantidade de dentina removida no nível da furca, não foram encontradas perfurações ou "rasgos", o que indica que todos os sistemas avaliados foram seguros nesse item, embora tenhamos observado que no nível 4, direção 4 (Ver Tabela LOST, 2002), sendo que a forma final da modelagem pode variar de dente para dente.…”
