COMPROMISED TEETH 3

Posted on by Jonathan Wong

Here is a 79yo healthy female with non-remarkable medical history. She presented with a history of massive palatal swelling due to perforation of the palatal root from attempted retreatment by her dentist. As you can see, a part of the previous casted post remains in the palatal root. We have identified the perforation on 2D imaging and confirmed with CBCT (we area aware of an untreated MB2 canal; however, there is no evidence of periapical pathology and retreatment will not be attempted until we can confirm that we have rectifed the palatal pathology). We have decided to attempt repairing the […]

PRE-OPERATIVE ASSESSMENT

PRE-OPERATIVE ASSESSMENT

Posted on by Jonathan Wong

The pre-treatment radiograph shows several technical deficiencies in the existing obturation: (1) short DB fill and (2) missed MB2. Radiographically there is a lesion associated with a seemingly well filled palatal root. Careful inspection; however, demonstrates that this lesion is asymmetrically placed off to the distal. This guides treatment towards exploring for apical bifurcations. The post operative image shows that there was in fact an apical bifurcation filled with necrotic tissue. The unlocated MB2 and short DB fill were both corrected for, but it is likely that the patient’s symptoms and infection were attributable to this complex apical anatomy of […]

MAGNIFICATION:

MAGNIFICATION:

Posted on by Jonathan Wong

One cannot treat what one cannot see…But if you can see more with assistance from the dental operating microscope, you will be able to make very small access openings into teeth/restorations. Here is a great example: recently placed crown and neither the patient nor referring Dr. were too keen on having the new prosthesis drilled through. Both changed their tune once they saw what we were able to do…this does not happen without enhanced magnification.   […]

Dental anatomy 6

Posted on by Jonathan Wong

Both of these teeth were treated at our office at 2 different times. Tooth #3 (on the right) was treated today while tooth #2 (on the left) was treated previously. Taken together, there are 9 canals between the 2 of them!! Pretty cool cases…we would have like to negotiate one of the canals on tooth #3 (the MB2) as it was non-patent; however we still feel that this represents a very favorable endodontic result!   […]

Selective Root Retreatment:

Selective Root Retreatment:

Posted on by Jonathan Wong

Here is a case where the mesial root of this molar displayed recurrent infection. In the other root, there is a properly placed fiber reinforced post. In order to save tooth and crown structure, the decision was made to treat only the infected root. Of course, this is done with very clear communication between the patient and us that we would be responsible for the tooth should the other root become infected. This way, we are able to keep the access opening through the crown as small as possible.. […]

ATYPICAL MORPHOLOGY –

ATYPICAL MORPHOLOGY –

Posted on by Jonathan Wong

These teeth from two patients this week were initially started by the restorative dentist. After careful debridement, the dentists noted that there were likely additional canals and referred the patients to Renovo. Interestingly, these teeth actually had three canals that split and merge at various levels of the teeth. A favorable outcome is anticipated and these cases demonstrate the benefit and need for microscope-aided endodontics. Aside: Most endodontists actually find the mandibular premolar (rather than a molar) to be the most challenging tooth to treat due to the prevalence of this type of complex anatomy in a relatively confined space.
