This patient presented complaining of pain from a discoloured upper right lateral incisor.
|
| |
|
|
 |
|
X-ray taken showed failed root canal treatment and a large apical cyst around the tooth apex. |
| |
|
|
 |
|
We first retreated the root canal and placed a new well packed root filling.
This ensures that the inside of the root canal is clean. |
| |
|
|
 |
|
We then raised a gum flap to have access to the cyst inside the bone at the end of the tooth root. |
| |
|
|
 |
|
You can now see the root apex once the bone around it is removed. |
| |
|
|
 |
|
Here you can see the cyst being removed from around the root. |
| |
|
|
 |
|
You Can now see the extent of bone loss caused by the cyst. |
| |
|
|
 |
|
The very apex of the root is then removed. |
| |
|
|
 |
|
End of root MTA root filling material was placed to seal the very end of the root. |
| |
|
|
 |
|
We placed bovine derived bone graft material known as (Bio-Oss) to fill in the bony cavity created by the cyst. |
| |
|
|
 |
|
The gum flap was then closed with resorbable sutures. |
| |
|
|
 |
|
The X-ray taken at the end shows the root filling, Apicectomy and bone graft. |
| |
|
|
| |
|
|
| |
|
|
| |
|
|
| As you can see from the above case, its important not to allow a cyst to expand and damage more bone. If a root filling has failed, prompt treatment is critical in order to prevent cyst formation and bone loss. |

| Root Canal Treatment |
| |
|
|
| |
|
|
 |
|
This patient presented with grossly decayed tooth with buccal cervical decay extending below the bone level.
Such deep decay would pose a serious problem for any dentist wishing to restore this tooth. |
| |
|
|
 |
|
We Initially thought about extracting this tooth and placing an Implant.
However due to medical problems, this patient only has 60% bone density.
Also this tooth was her only lower right molar tooth still present in her mouth.
Extracting this tooth would have left this patient with no posterior bite on that side. |
| |
|
|
 |
|
So we root filled and crowned the tooth in order to save this tooth.
Note how deep the crown margin extends well below the bone level.
You can see a well packed root filling and a very good crown margin. |
| |
|
|
 |
|
This is the crown visible in the mouth.
She did not suffer any pain during the procedure. |

| Failed Molar Root Canal Treatment |
| |
| |
|
|
| |
|
|
 |
|
This patient presented with pain from his lower 1st molar.
The tooth had been root filled a few years ago but the root filling had failed. |
| |
|
|
 |
|
We did a re-root canal treatment with strict rubber dam isolation for a sterile field.
The canal lengths were measured with X-ray. |
| |
|
|
 |
|
The tooth was re-root filled after copious irrigation and cleaning.
As root canal treatment makes the tooth more brittle, this tooth will need a crown to prevent fracture of the tooth.
The tooth behind needs a filling as it has decay. |
