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 Dr. Boris Kostiuk from Oshawa, Ontario; Dentocillin was introduced in 1950; penicillin was thought to kill the acid-producing bacteria that was blamed for causing cavities; many dentists were not convinced of its efficacy, claiming that since the penicillin did not cause ill-effects, it was probably due to it being rinsed out of the mouth so quickly, in which case it would not have any effect on tooth decay either
