| Abstract: | Objective To explore the effective method for C-shaped root canal preparation.Methods The C-shaped canals of mandibular second molars were treated with the so-called 'drawing-fish-net' root canal preparation technique.Root canal obturation result was evaluated with routine post-operative dental film.Results The C-shaped canals were enlarged and shaped well and the well-distributed X-ray obturation images in isthmus of C-shaped canals were acquired.Conclusion The technique described in this paper is effective in preparing C-shaped canals,as well as in avoiding perforation of canals during preparation. |
