David trained in the United Kingdom, and was appointed upon completion of his specialist training to the University of Hong Kong as Head of the Oral Radiology Unit. He has also held appointments at the universities of Edinburgh and Bergen. David has extensive publications (under MacDonald-Jankowski) principally on the radiological aspects of the epidemiology of disease affecting the face and jaws. His paper, 'Fibro-osseous lesions of the face and jaws' in Clinical Radiology (a medical radiology journal) was the 3rd most downloaded for the 2003/04/05 academic years. Today, it is still ranked within that journals 'Top 25 most downloaded.' Interests are history (has published a book on the Scottish Jacobite heroine, Flora MacDonald) and certain aspects of law (has a law degree). 
 
In 2007 David graduated DDS by thesis (dissertation; DDS in the UK is equivalent to a high-quality PhD) from the University of Edinburgh and passed the fellowship examination in Oral and Maxillofacial Radiology of the Royal College of Dentists of Canada.  
 
In 2011, David's book 'Oral and Maxillofacial Radiology: a diagnostic approach' was published by Wiley-Blackwell (ISBN 978-0-8138-1414-8). Oral and Maxillofacial Radiology: A Diagnostic Approach "provides clinicians of various disciplines and skill levels — including non-radiologist readers and senior students — a practical and systematic approach to diagnosing lesions that affect the face and jaw. The book contains a multitude of clinical images, practical examples and flowcharts to facilitate differential diagnosis. To reflect the scope of humanity, the book presents common and significant lesions within four broad ethnic groups, then focuses on appropriate imaging. Several chapters are co-written with a medical radiologist, Dr. Monty Martin, chief of Diagnostic Radiology, BC Cancer Agency, to bridge the gap between current textbooks in oral and maxillofacial radiology and those to do with the head and neck. The neck and base of the skull are locations where lesions are likely to be found." (adapted from www.dentistry.ubc.ca/between-the-covers-new-books-by-faculty-members/
 
This textbook has received 3 outstanding reviews. David has contracted with Wiley to produce a second edition which will be directed towards medical radiologists in addition to dentists. David has already assembled an outstanding medical and dental team of outstanding co-authors. 
 
David has also contributed a chapter on Oral and Maxillofacial Radiology to Lamey, Salinas, Carr, Koka and Eckert's second edition of Diagnosis and Treatment in Prosthodontics (Quintessence 2011).  
 
David's interests outside the radiology of the face and jaws have resulted in publications on Barrett�s� Oesophagus and scleroderma. 
 
David is the Dental Specialist�s representative of the council of dental accreditation OF Canada (CDAC). 
 
In December 2015 David was elected by his dental colleagues to represent them as Senator in the UBC Senate.

BOOK

 

'Oral and Maxillofacial Radiology: a Diagnostic Approach' published by Wiley-Blackwell.

 
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."
 
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."
 
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.
