After completion of endodontic chemomechanical debridement you can expect to have
1. removed all tissue from the entire root canal system.
2. caused some temporary inflammation.
4. completely sterilized the root canal.
4. left some areas of the root canal system incompletely cleaned.

   The complex anatomy of the root canal system (e.g. lateral canals) makes debridement difficult, especially in the apical delta region. Furthermore, bacteria have been shown to invade dentinal tubules and thus they may not be removed totally by chemomechanical debridement. Thorough cleaning, shaping and irrigation with disinfectants may not result in a completely sterile root canal system. Leakage cannot be totally prevented by any material/method available today, percolation of nutrient-rich fluid followed by bacterial regrowth may occur. Temporary inflammation may occur.
