title: [Evaluation of the canal shaping duration with Pro Taper: 50 cases--clinical experience].
abstract: BACKGROUND
  Shaping canal is one of the most important steps in endodontic treatment. It allows the cleaning solutions to reach the totality of the canal and to control any infection of the canal system. To achieve this goal is not without difficulty with the steel instruments, because of their rigidity. Recently, the Nickel Titanium instruments were introduced in Endodontics, to allow a setting form technically simplified and faster The aim of this study was to evaluate the duration of the canal shaping with the Pro Taper system.
  
  
  METHODS
  This exploratory study was carried out in Conservative Odontology and Endodontics service (OCE) of the department of Odontology of Faculty of Medicine, Pharmacy and Odonto-Stomatology of the University CheikhAnta Diop of Dakar in 2006. Sixty nine root canals (50 teeth) were shaped with ProTaper.
  
  
  RESULTS
  The results showed that an average time of 17.35 minutes was necessary for the shaping of the long canals against 15.38 minutes for the middle canals and 14.29 minutes for the short canals. The average duration of canal shaping of the one-root teeth is 13.76 minutes and 17.77 minutes for the plural root teeth.
  
  
  CONCLUSIONS
  Taking into account the necessity of maintaining the teeth on the arcade during long year; include that we have now to respect imperatively the biological principles during the canal shaping in a restricted duration to realize a dense and hermetic canal obturation of the canal system in the same meeting. The Pro Taper system is so a reliable means.
