Maxillofacial fibro-osseous lesions. Clinical Radiology. 2015;70:25-36. Invited by the Editor-In-Chief to update 1.

Already been cited 8 times by Google & 3 times by Scopus.   Bryant R, MacDonald-Jankowski DS, Kim K. Does the type of implant prosthesis affect outcomes for the completely edentulous arch? International Journal of Oral Maxillofacial Implant 2007; 22 suppl: 117-139. It was the first systematic review to reveal the long-term outcomes of dental implants. It is still the most comprehensive systematic review on this topic. It has been cited over 100 times on Google.   MacDonald DS et al. Diagnosis and management of calcified carotid artery atheroma: dental perspectives.   Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology 2012: 114: 533-547. This is the first report to place the importance of these lesions in a medical context.

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.   EDUCATION   2 courses in adult pedagogy; University of Bergen & UBC's Faculty Certificate Program in Teaching and Learning in Higher Education (UBCFCPTLHE).   Progressive approach to teaching; wholly evidenced-based and student-centered learning. Textbook was especially written to complement all OMFR courses at UBC.   Creative approach to curriculum development. The graduate course (DENT 756) class participation is modelled on the business-school group-presentation format.     IMPACT   Clinical Radiology paper (Paper 1.) corrected the longstanding misunderstanding about fibrous dysphasia of the jaw, which was resected although it is not to be a tumour.   Unique system of SRs has not only been used by others, but also frequently cited.   MacDonald's unique division of humanity into global groups has revealed the significant differences that can exist between them. (Paper 9 is the most recent.)   Regularly petitioned the College of Dental Surgeons of British Columbia (CDSBC) since 2004 to produce regulations for CBCT. Collaboration with CDSBC resulted in their release in late 2015.
