Abstract:

The purpose of this paper is to prove that corect access cavity is an important step in endodontic treatment and all the other steps depend on this preliminary phase.Material and method. In our study we used a number of 50 monoradicular and pluriradicular teeth, with different grades of radicular curvature. Cavity access was made using the adequate burs in order to obtain outline form and facilitate the action of canal instruments. Results. In order to obtain outline form cavity walls often have to be extended to permit both corect cleaning and shaping and corect tridimensional obturation. Discussions. An access cavity that has been prepared improperly in terms of position, depth or extent will hamper the achievement of proper results in endodontic treatment and will ultimately lead to failure by either root perforation, „ledge” or „shelf” formation within the canal, instrument breakage, zipping or apical transportation. Conclusions. Complete control of the clinician over the enlarging instruments is very important and this is very easy to obtain by creating a corect access cavity
