This case is presented by Drs Stephen Cho & Ian Furst at Coronation Dental Specialty Group & Cambridge Memorial Hospital A 56 year old male has a partially impacted wisdom tooth #3.8, communication to the mouth, pericoronitis and a complaint of persistent pain associated with the tooth. You take a panorex and note the overlap of the inferior alveolar nerve.

Is there a scientifically valid way of determining which developing wisdom teeth are likely to become partially impacted? The ...Read More »
A 35-year old man develops a serious infection from an impacted 2.8. The tooth is extracted and the infection is drained but he develops a serious bleed 3 days after surgery (from the internal maxillary artery) which requires neuroradiology embolization. One month later, he has recurrent swelling around the left temple and TMJ but also complains he feels numbness in the entire trigeminal nerve, including V-1. Attached is a slice of the MRI and an intraoperative shot. Why can’t he feel his forehead?Read More »

In this case, an 11 year old girl presents with unerupted 1.3 and 2.3. The height of them, on panorex, is extraordinary and you decide to get a cone beam CT. See the CT below and tell ...Read More »
Debating Imaging Radiation Exposure: Study Illustrates Importance of Considering Short-Term vs. Long-Term Risk.Read More »
With the explosion of cone beam CT the amount of data being generated is staggering. Anders Ynnerman gives a TED talk about how data is being stored and re-processed to help us better understand the human body. He covers the size of the data explosion, virtual autopsy, functional MRI and more. A very interesting lecture.Read More »

What is the impact of emerging radiographic technologies on cumulative patient ionizing radiation exposure?
(Content under development) The following question was submitted by a practising dentist: I have seen an exponential growth in the marketing of CBCT to dentists (shouldn’t we ALL have one?), and have seen an emerging trend of dentists using them to reverse engineer pans etc. Most recently, an advert came across my desk where bitewings engineered from a pan are the answer. What is the impact of emerging radiographic technologies on cumulative patient ionizing radiation exposure? JCDA Editorial Consultants Drs Ernie Lam of the University of Toronto, Garnet Packota of the University of Saskatchewan and Elaine Orpe of Vancouver provided these ...Read More »
