Description

Excerpt from The Dental Cosmos, 1861, Vol. 2: A Monthly Record of Dental Science The second chapter will be devoted to the study of the genesis and constitution of the follicle, considered from the moment Of the appear ance of the bulb, which is always first produced, until the commencement Of the production of the tooth - that is to say, to the birth Of the first hollow crown or cap of the dentine. The third chapter will treat Of the manner of origin and development of the constituent parts Of the tooth - ivory, enamel, and dentine; and also Of the structure of the formative organs of these parts. Finally, in the fourth and last chapter, we will describe, in discussing them, the processes that have been followed in order to ascertain the anatomical and physiological particularities mentioned in the first three chapters. The Observation of the facts upon which this treatise rests is, if not easy, at least fruitful in results of great accuracy. The transparency of the parts is favorable to observation, and permits great distinctness in fol lowing the outlines which limit eachiof the organs under consideration; these outlines are at first diffuse, then more and more distinct. When an iso lated preparation is studied for the first time, it is found very perplexing to give an exact interpretation of such and such of these outlines, or of the nature of the organ limited by them; but as the same preparation may unite in itself a series of juxtaposed follicles, the constancy and regularity Of the relations which affect the organs that constitute them give a certain preciseness to the decision of the nature of the objects. Finally, this decision becomes at the same time easy and accurate, when the Observation is made on a series of pieces from the same subject at different ages, or on pieces belonging to distinct species. The compari son of these organs at their different periods in the same animal, and the comparison of the follicles in different species, always Show Similar ana tomic relations, (excepting some secondary differences in form and Size;) this leaves no place for doubt relative to the nature and Office Of each Of the constituent parts Of the follicular apparatus.
