Permanent Trauma: Root treating non-vital immature incisors

Question 1

What material can be used to create a hard apical barrier?

Answer 1

Mineral trioxide aggregate

Question 2

How is MTA used to create an apical barrier?

Answer 2

• MTA placed at apex, create a 4-5mm apical plug
• Check placement radiogrpahically
• Remainder of the canal filled with MTA or backfilled with GP at a subsequent appoinment to allow inital MTA to set

Question 3

What alternative material to MTA is also used for endodontic treatment of immature teeth?

Answer 3

Calcium hydroxide
- Injecteable Ca(OH)2
- Non-setting calcium hydroxide paste can be placed 1mm of the radiographic apex
- Once apical barrier is achieved, GP with sealer is used to obturate the canal

Question 4

Why is non-setting calcium hydroxide an ideal material?

Answer 4

• Disinfects the canal
• Induces calcification of the apical tissue
