Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008.
The Faculty of Dentistry was created in 1925 when the University of Toronto took over teaching from the Royal College of Dental Surgeons of Ontario; the two had been affiliated since 1888, though the RCDS had been teaching dental students since 1868; the Faculty is now the largest in Canada (2010), graduating up to 100 dentists per year and is the foremost dental research centre in Canada.

Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008.
this item was donated and created by Dr. Oskar Sykora from Halifax, Nova Scotia; he states that many shade guides came for porcelain teeth only, or they had more selection for anterior teeth than posterior teeth, or they ignored the posterior teeth altogether; these shade guides were created by Dr. Sykora to overcome those limitations; his method involved removing the incisors (anterior teeth) from the manufacturer's guide and replacing them with premolars selected from all the manufacturers; he did this by drilling a small hole in each tooth and screwing them into the original shade guide holder
