pulp regeneration Flashcards
What is pulp regeneration?
Regeneration of new vital tissue in an empty & disinfected root canal space.
Which patients are ideal candidates for pulp regeneration?
Young patients (7-12 years) with immature (open) apex and vital inflamed or necrotic pulp.
What type of anesthesia is recommended during the second visit of pulp regeneration?
3% mepivacaine without vasoconstrictor to allow bleeding.
What is the purpose of using 17% EDTA in the second visit?
To remove the medicament and allow the production of growth factors from dentine.
What concentration of NaOCl is used during the first visit?
1.5% NaOCl, 20 mL per canal, for 5 minutes.
Why should chlorohexidine be avoided in pulp regeneration?
It kills stem cells.
What is the scaffold used in pulp regeneration?
Blood clot, PRP (Platelet Rich Plasma), PRF (Platelet Rich Fibrin), natural and synthetic polymers.
What is the role of a scaffold in pulp regeneration?
It acts as a matrix to hold stem cells and allows the travel of growth factors to stimulate stem cells.
What is SCAP in the context of stem cells?
Stem Cells of Apical Papilla (SCAP).
What is the primary goal of pulp regeneration?
Elimination of symptoms and evidence of bony healing.
What is used to induce bleeding during the second visit?
Over-instrumentation with an endo file or explorer.
Why is minocycline avoided in triple antibiotic paste?
It can cause tooth discoloration.
What is the success rate range for pulp regeneration?
90% to 100%, though 100% is not typically attainable.
What are the secondary goals of pulp regeneration?
Increased root wall thickness and/or root length.
What is the tertiary goal of pulp regeneration?
A positive response to vitality testing, indicating more organized vital pulp tissue.
