A Little Treatise on the Teeth
註釋Bartolomeo Eustachio (1520-1574) was one of the great anatomists of all time. In any ways his anatomical studies were more detailed and comprehensive than those of his more famous contemporary Andreas Vesalius (1514-1564), but his major studies remained unknown until their eventual publication in Amsterdam in the beautiful edition of 1714 ... Eustachio's contributions to the development of dental science were substantial In addition to the many conceptual advances concerning tooth development and function, based on anatomical dissections, he also presented more detailed plates of the musculature of the face, floor of the mouth and neck as well as detailed plates of the tongue and of the crown and roots of the teeth ... In addition to the first clear description of dental pulp and root canal, Eustachio described the periodontal membrane for the first time and thought of it as a gomphosis type of joint. (He) understood that the crowns of the teeth were composed of enamel overlaying dentin and this was the first description of the two separate tissues of the tooth. Occlusion was described in detail in man as well as animals. The permanent teeth were found to develop from dental follicles, and not from the roots of deciduous teeth as postulated by Vesalius.
