Apexification

Question 1

What is the purpose of apexification?

Answer 1

Induce root end closure at apex of necrotic tooth with incomplete roots

Question 2

How does Calisept function?

Answer 2

Stimulates Root End Closure via Hertwig’s Epithelial Root Sheath (HERS)

Also pH 12.4 –> Bactericidal

Question 3

What does calcium hydroxide do?

Answer 3

stimulate formation of dentine bridges and hard tissue barrier in roots

Question 4

Apexification technique with Calasept

Answer 4

Working length = 2mm short of apex

Recall 3mo to check for calcific barrier –> if not, redo CaOH Q3mo

Question 5

What is MTA?

Answer 5

Mineral Trioxide Aggregate
(tricalcium silicate)

Has bone healing properties as well

Question 6

MTA pros/ cons:

Answer 6

Pros: 1 appt apexification

Cons:
4 hours setting
(req moisture to set)
$$$$

Question 7

MTA vs Calisept

Answer 7

1) more studies on MTA
2) better apical tissue regeneration
3) better histological outcome
4) better clinical success rate
5) worse handling
