Comparación in vitro de la conformación bio-mecánica de los conductos mesiales del primer molar inferior entre los sistemas de instrumentación mecanizada Wave One y Wave One Gold
During the biomechanical preparation of the root canals, there is a tendency to remove dentin, especially in the danger zone; access with rotating instruments can cause excessive tooth wear, decreased hardness and thinning of the walls, without preserving the original anatomy of the dental conduit....

Ավելացրեք ցուցիչ | Ամփոփում: | During the biomechanical preparation of the root canals, there is a tendency to remove dentin, especially in the danger zone; access with rotating instruments can cause excessive tooth wear, decreased hardness and thinning of the walls, without preserving the original anatomy of the dental conduit. The objective of this research compared the mechanical conformation between the systems Wave One and Wave One Gold, in the mesial conduit of the lower first permanent molar. An comparative study was carried out - in vitro of a descriptive type, using the analytical method; the type of sampling was random for convenience. 40 lower molars extracted were selected and divided into two groups. The distal root was sectioned and the mesial roots were homogenized to 18 mm in the apex-coronal direction; initial photographs were taken through a steromicroscope, to 5 mm below furca. Group A: 20 lower molars instrumented with the rotary system Wave One Gold, group B: 20 lower molars instrumented with the system Wave One, after the preparation, post-operative photographs were taken, that were edited with the Program AutoCAD, comparing the difference of the initial extension of dentin and dentin post instrumentation. The millimeters were compared from one system to another, after the biomechanical preparation and there is no statistical significant difference (p <0,05) when instrumented, with the two systems at 5 mm below the furcation area in relation to tooth wear; and in relation to the degree of deformation the two systems conserve the original anatomy of the conduit.
