Excerpt from The Dental Review, Vol. 2: Devoted to the Advancement of Dental Science
Oils and fats, before they reach the dentist, to lubricate a motor, disguise the taste of a drug, or give a keen edge to an instrument on a Whetstone, pass through many processes in rend erin... g, expression, or distillation. It is not, however, of the pro cesses of their extraction that I purpose speaking to-night, as much as it is of their use and value in dental surgery. Oils are either fixed or volatile, animal, vegetable, or mineral. The min eral oils have a very small place in the practice of dentistry. Oil of Shale and petroleum, vaseline, etc., are all useful in the labora tory, and for heating and lighting, as well as for lubricating and cleansing purposes. It is presumed that no special directionsfare necessary for their particular uses by the dentist. The principal animal oils are seal oil, whale oil, cod liver oil, butter, tallow,ior suet, lard, or lard oil, Dippel's animal oil, spermaceti, from the brain of the whale, and Chinese wax. The heavy vegetable oils are palm, olive, cotton seed, colza, almond, castor, linseed, and cocoanut. Dippel's animal oil may become, through its combina tion with iodine, a very valuable adjunct in dental practice. The drug known as iodol, is composed of Dippel's oil and iodine. This ethereal oil is obtained from the dry distillation of bones and other animal matters, although Dippel prepared it originally from dried blood about 1711. It is sparingly soluble in water, the propor tion of the oil dissolving in water being the same as creosote 1-80.
