Surgical Endodontics
Indications |
.Large periapical pathologies
.Incomplete or difficult Endodontic Treatments .Endodontic accidents and overfilling .Teeth non-responsive to endodontic therapy .Obstructions in the canal such as posts .Fractures in the apical third of the root |
|
|
Surgical endodontics
Contra indications? |
.Whenever endodontic treatment is possible
.Short roots .Acute phase of disease .Non-treated non-stable systemic conditions .Multiple surgical attempts - consider extraction and implants |
|
|
Surgical endodontics
Techniques? |
.Surgical periapical drainage
.Periapical curettage .Apicectomy .Apicectomy + retrograde filling .Fenestration .Rizectomy / hemisection .Decompression / marsupialization |
|
|
Apicectomy is done before or in conjuction with the periapical curettage.
T/F |
False
It is done after or in conjunction with the periapical curettage |
|
|
