1. What are the indications for a vital pulp therapy?
Vital pulp therapy is indicated in teeth with incomplete apical development, primary teeth, teeth that would be difficult to be treated endodontically and teeth with pulpal inflammation confined to a small segment of the coronal pulp.
2. What is Apexogenesis?
A pulpotomy procedure that is indicated in a tooth with an open apex to allow completion of apical closure, with a vital pulp is called as Apexogenesis.
3. What is a Blunderbuss canal?
When trauma or decay causes a pulpal exposure or periapical involvement prior to the completion of root formation, an open apex results in which there is no conical taper to the canal. The canal is wider towards the apex than the cervical area. This is called a blunderbuss canal.
4. What are the materials used to fill the canal in apexification?
A thick paste that contains calcium hydroxide and CMCP is placed in the canal till it reaches the apical portion, to stimulate the tissues to form a calcific barrier.
5. What are the possible apical conditions in 6 months follow up radiograph of a patient treated by Apexification?
- No radiographic change, but an inserted instrument encounters blockage
- Radiographic evidence of calcified material at the apex.
- Closure of the apex with no change in the canal space
- Continuous apical development with canal space closure
- No radiographic evidences, persistence of symptoms and an increase in the size of the periapical lesion.
