Q
2) aim of study
A
to find out if revascularization and ingrowth of new pulp tissue is influenced by removal of original pulp tissue before autotransplantation?
3
Q
- Background:
when autotransplanting teeth:
A
- you might enlarge the apical foramen
- you might cryopreserve the teeth
- pulp doesn’t survive the cryo process when it’s kept in the tooth
- it has been demonstrated previously that revascularization and ingrowth of new tissue can occur in an empty pulp chamber
4
Q
- Results:
A
- in the group with pulp left in situ, 80% of teeth had 1/3 - 2/3 chamber filled with live pulp 90 days later
- in the group with pulp removed, 80% had little or no vital tissue in pulp chamber
- the necrotic masses that develop in the original pulp tissue after transplantation may stimulate repair of the pulp.
5
Q
- Conclusion
A
in case of autotransplantation of teeth, it is advisable to leave the pulp tissue in situ to stimulate the revascularization and ingrowth of new tissue after transplantation
