prep without local anaesthetics will not inflict any discomfort. This will act to confirm

the pre-treatment diagnosis that the abscess or draining fistula originated from said tooth.

Overfilled Sealer Often Indicates Presence of Lateral Canals and Does

Not Affect Healing

Healing will commence once thorough cleaning, shaping, and disinfection of the root
canal system has been completed. However, a properly obturated system further

illustrates the thoroughness of the previous steps. Clinically, obturation is aided by the
use of sealer, as it is difficult getting warmed gutta percha into all small and irregular
accessory canals. The sealer needs to be biocompatible to not interfere with healing. Dr.
Schilder recommended materials that can be resorbed by the body in a reasonable time,
allowing enough time for the macrophages to engulf the sealers, but not too fast that it

abolishes the apical seal prior to healing resulting in reinfection of the apical portion. This
way, at the six-months or one-year follow-up radiographs, healing of the apical lesion,
reformation of lamina dura, and resorption of the overfilled sealer will be seen.
