clean n shape final

  • Endodontic treatment is divided into 3 main phases
  • Bio mechanical preparation
  • Disinfection
  • Obturation
  • The first step for effective BMP is straight line access
  • Next step is exploration of the canal, extirpation of remaining pulp tissues and gross debridement of necrotic tissues
  • Followed by proper instrumentation, irrigation and debridement and disinfection of the root canal
  • Heat, probably during sterilization cycles could even¬† restore the molecular structure of NiTi (Nickel Titanium instruments: Applications in endodontics)
  • Sterilization procedures are safe and produced a significant increase in fatigue resistance of the instruments (IEJ 39,709;2006)
  • Cryogenic treatment resulted in microhardness but this increase was not detectable clinically(IEJ,38,364,2005)
  • Linear deforming forces shunted into stepwise transformation from austenitic to martensitic form-leads to elastic deformation of 7%
