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 by George Oterbauer from Toronto, Ontario; it would have been attached to a dental unit, as opposed to standing alone; this was the first Airotor drill unit produced; the Airotor, using a high-speed air turbine system, replaced earlier drills that used a water turbine system; this technology introduced the era of 'sit-down' dentistry due to the high speed (up to 300 000 RPM) of the drill; it is still used in the present day
