Regenerative endodontic therapy – What is it?
Regenerative endodontic therapy technique for the revitalization of a necrotic immature tooth.
- Tooth must be necrotic pulp with immature apex
- Minimal to no dentinal manipulation
- Place intracanal medicament (usually triple antibiotic) DAP better cause no stain of minocycline (metronidazole and ciprofloxacin) Sabrah 2013
- mTAP (modified TAP) ciprofloxacin, metronidazole, cefaclor Thibodea 2007 Jan/Feb Ped Dent. Showed no stain but Akcay 2014 JOE said did. Akcay said only DAP=no stain
Step by step for regenerative endodontic therapy with ADA dental codes
Step 1 Code 3351 Debride without dentinal wall manipulation and irrigate with 1.25%-3% NaOCl, place triple antibiotic, and seal.
Interim step if needed 3552 Repeat step 1
Step 2 3354 pulpal regeneration Remove medicine with 1.25%-3% NaOCL, EDTA (CA?), create blood clot, place PRF?, seal MTA and filling. Do not use vasoconstrictor.
Regenerative endodontic therapy research
10% citric acid could give a better biological response than EDTA according to Ivica 2019 JOE.
