Instrumentation of finely curved canals.

The conclusion to be reached should not be that one method of enlargement is better than another in finely curved canals, or that one filling material is better than another but rather that all materials and methods have strong points and weak points which should be taken into consideration when endodontic therapy is performed. The stepback enlargement technique is probably the best technique for enlarging finely curved canals, but problems may be experienced with it also if careful procedures of instrumentation and cleansing are not followed. If these factors are kept in mind it will help us to provide the highest possible quality of endodontics.
