Research Areas:

Dr. MacDonald's main research areas are systematic review in diagnostic radiology and Barrett's oesophagus, radiological pathology of the face and jaws (including incidental findings), scleroderma, educational research in radiology, infection control and cone-beam computed tomography (CBCT). The Barrett's review has been adopted by the NHS in the UK. He was radiology lead in the CIHR Canada-wide study on scleroderma, the largest yet to date. Other largest –to-date case series are of incidental findings on dental panoramic radiographs and on lateral cephalograms, and on lymphomas of the jaws. Furthermore, the largest case series that displayed CBCT superiority over conventional radiography with regards, to diagnostic and therapeutic impacts (high tiers on Fryback and Thornbury’s 6-tier hierarchy for the efficacy of diagnostic imaging) in endodontics.

The 2003/2004 SARS pandemic coincided with Dr. MacDonald’s arrival at UBC and the building of the Oral Health Centre. As a result the infection control of all digital radiographic systems was optimised, including the intraoral phosphor-plate bagging system. Dr. MacDonald, at the advent of the COVID-19 pandemic played a lead role in radiology’s response. He was lead author of the 2021 AAOMR’s guidelines and was invited to update them in 2022’s Int. Dent. J’s ‘New normal radiology’ in order to assist the global dental profession’s return to offering as full a service to their patients.

Teaching Areas:

Dr. MacDonald's principle teaching area is diagnostic radiology of the face and jaws, including cone-beam computed tomography, in the undergraduate and graduate curriculums. The core text especially written for all diagnostic radiology teaching at UBC dentistry is his successful textbook 'Oral and maxillofacial radiology: a diagnostic approach' published by Wiley. This was updated in 2020 and included contributions from medical radiologists, functional imaging physicians and a radiation oncologist (IBSN 9781119218708).

Since the acquisition of radiological skill essential to the practising dentist, whether generalist or specialist, cannot be simply acquired by osmosis, active approaches to ‘student –centred learning’ are employed by OMFR teachers at UBC Dentistry. Teaching in the undergraduate courses is by assessed Socratic-style (question and answer) lectures and small-group sessions, and by examinations solely based on conventional radiological and CBCT cases. Teaching in the graduate (dental specialty) courses is by small group (based on specialties) presentations delivered in the manner similar to business-school and law-school programs.

1. Dr. Wenzel wrote in the Danish Dental Journal (Tandlaegebladet 2011) that
 
"This is not a traditional textbook in [oral and maxillofacial] radiology since there is an emphasis on description of high-tech imaging techniques such as CT scanning, magnetic resonance, positron emission tomography and ultrasound."
 
2. Drs. Danforth and Mah stated in the Journal of Clinical Orthodontics (2012) that
 
"As Dr. David MacDonald states in his preface, "The purpose of this textbook is to guide diagnosticians of all skill levels in generating a diagnosis of lesions affecting the face and jaws. This goal is thoroughly accomplished in 18 chapters divided across four major subject areas."
 
"All chapters include high-quality illustrations with concise, readable legends, along with excellent decision-making flow charts to help guide the reader through the interpretive process."
 
"Each topic is well referenced with current evidence-based studies and epidemiological data that can be useful in identifying radiographic lesions and developing differential diagnoses."
 
3. Dr. Tong wrote in the International Journal of Oral and Maxillofacial Surgery (2012)
 
"Overall, this work presents a large volume of information in 351 easily readable pages. It contains updated information on most aspects of maxillofacial imaging in one text. The different parts of the book can be studied separately, according to the needs of the individual clinician."
 
"The superb image quality and succinct texts make it easy to recommend to dental practitioners, maxillofacial specialist and residents embarking on their careers."

 
Wiley requested a 2nd Edition of this textbook directed also to medical radiologists. IBSN 9781119218708 Launched Mid-November 2019, with year of publication 2020.
