This extremity (Fig. 278) is occupied by a cavity called the external dentalcavity, c, which separates two borders, an anterior and a posterior ; two sides, anexternal and an internal. These two borders are unequal. The anterior, a, is more prolonged andmore salient than the posterior ; it is thin, quite sharp, slightly convex trans-versely, and is the first to appear in the eruption of the tooth from its alveolus ;its pressure causes absorption and perforation of the gums. The posterior border, b, less salient than the anterior, sometimes has anotch in its middle part, which renders the external dental cavity much lessregular.
