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. William Mills from Etobicoke, Ontario; this type of anaesthesia would be used on patients who were needle-phobic, not able to have chemical anaesthetics, or did not want post-treatment numbness; electrodes were taped to the face, and the muscles were stimulated via a signal from the battery-operated unit; the patient themselves controlled the level of stimulation; one study, presented at the 2001 meeting of the American Public Health Association, found that a majority of patients found electronic anaesthesia to be acceptable; it also states that 3M's product was pulled from the market, however, because the marketability wasn't there

Research Facts
This is the 'Junior Balancer' model that was introduced in 1934 and was smaller, simpler, and less expensive of the 'Deluxe' and 'Senior' models; casts were directly mounted to the instrument; usually there were two attachments that could be added to the Junior Balancer, the Occlusal Arc Guide and the Flat Plane Guide. Hagman designed the instrument according to his belief that the mandible functioned in an arc from centric relation. 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.

Research Facts
Cyclopropane is an anaesthetic when inhaled. In modern anaesthetic practice, it has been superseded by other agents, due to its extreme reactivity under normal conditions: when the gas is mixed with oxygen, there is a significant risk of explosion. Cyclopropane had no commercial application until Henderson and Lucas discovered its anaesthetic properties in 1929; industrial production had begun by 1936. This meant induction of anaesthesia by inhalation of cyclopropane and oxygen was rapid and not unpleasant. However at the conclusion of prolonged anaesthesia patients could suffer a sudden decrease in blood pressure, potentially leading to cardiac dysrhythmia; a reaction known as "cyclopropane shock".For this reason, as well as its high cost and its explosive nature, it was latterly used only for the induction of anaesthesia, and has not been available for clinical use since the mid 1980s. Cylinders and flow meters were coloured orange. Cyclopropane, also called trimethylene, explosive, colourless gas used in medicine since 1934 as a general anesthetic. Cyclopropane is nonirritating to mucous membranes and does not depress respiration. Induction of and emergence from cyclopropane anesthesia are usually rapid and smooth. A mixture of about 5 to 20 percent cyclopropane in oxygen is administered by inhalation. Because of the flammability and expense of cyclopropane, it is usually used in a closed (rebreathing) system, in which an absorbent chemical, such as soda lime, removes exhaled carbon dioxide, and the anesthetic is recirculated. The chemical formula is C3H6.
