title: [The area of dentinal diffusion at the time of the manual preparation of root canals].
abstract: In this current piece of work we study the area of dentinal diffusion obtained with various irrigating agents which eliminate the smear layer: critic acid at concentrations of 10, 25 and 50%, 15% ethylene-diamino-tetraacetic acid (EDTA), and REDTA (compound of EDTA). All the agents proved their efficiency in eliminating the smear layer, which was corroborated by use of the sweep electron microscope and objectified using computerized image analysis, thus obtaining different diffusion areas with the various irrigating solutions used.
