Evaluation of pH and calcium ion diffusion from calcium hydroxide pastes and MTA.
The aim of this ex vivo study was to evaluate changes in pH and calcium ion diffusion through root dentin from calcium hydroxide (Ca (OH) 2) and mineral trioxide aggregate (MTA) pastes at 7, 30 andExpand
Apical extrusion of debris by manual and mechanical instrumentation.
The aim of the present study was to assess the presence of apically extruded debris and evaluate the influence of canal curvature on the amount of debris produced by manual and mechanical techniques.Expand
Transportation of curved canals instrumented with manual and mechanical techniques.
The purpose of this study was to compare the effect of manual and mechanical instrumentation techniques in curved root canals using area of dentine removed and canal axis movement as the end-points.Expand
Shaping of curved root canals instrumented with stainless steel and nickel titanium files.
The cleaning efficiency and the quality of the surgical preparation is mainly conditioned by root canal anatomy, the instruments and the technique employed. The purpose of the present study was toExpand
