A text-book of dental histology and embryology, including laboratory directions . r> DISTRIBUTION OF THE DENTAL TISSUES 31 the occlusal thirds on the buccal and lingual is usuallycurved in the opposite direction. That is, while the surface Fig. 7. Dento-enamel junction. 32 THE DENTAL TISSUES of the enamel is convex, the surface of the dentine is will be seen that this not -only gives a greater thicknessto the enamel in the region which will resist abrasion,but also gives it a firmer seat upon the dentine. (Studyillustrations in Chapter X.) The dento-enamel junction isseldom a smooth, even surface, but will appear scallopedin sections, projections of dentine extending betweenprojections of enamel (Fig. 7). In three dimensions thismeans that rounded projections of the enamel rest inrounded depressions of the dentine surface, and pointedprojections of the dentine extend between the rounded pro-jections of the enamel. This is similar but much less markedthan the interlocking of the papilla of connective tissue withthe projections of the Malpighian layer of stratified squamousepithelium of the skin and mucous membrane. In somecases these projections of dentine into the enamel may bequite marked. This scalloping of the den
