A Clinical Study to Compare Two Revascularization Protocols to Treat Non-vital Teeth With Incomplete Root Formation

Both methods tested in this study disinfect the non-vital root canals and induce blood clot formation inside the root canal. One method places calcium hydroxide inside the root canal after disinfection and the blood clot is induced four weeks later. The other method performs disinfection and induction of blood clot in one appointment. The investigators hypothesize that both methods will obtain the same success rate in eliminating infection, increase in root length and canal walls thickness.

Collagen is placed on top of the blood clot, followed by white MTA. Glass ionomer is used to seal the access to the canal, which will be replaced by a permanent restoration 3 months later.
