BioMimetirc Conditioning of Human Dentin Using Citric Acid
CE Hours: 1.0 CE hour
In carious teeth, transforming growth factor beta 1 (TGF-β1) is released from the dentin matrix and possibly activated in an acidic environment. Conversely, EDTA solutions with a neutral to slightly alkaline pH are used in clinics to promote cell homing in regenerative endodontic procedures. We hypothesized that citric acid (CA) might be more beneficial.
At the conclusion, participants should be able to:
- Describe the concept of cell homing in the context of Regenerative Endodontics;
- Discuss the key role of TGF-β1 in this concept;
- Evaluate the role of pH in root dentin conditioning for regenerative procedures.
