Fia. 104. l'hotogr;iph of a split upper first iimlnr with an occlusal decay of ordinary form.
Note a small beginning of decay of rnamcl in the distal surface, and a decay beginning in the cemen-
turn. This lallcr is characteristic of decays which occur because of crowding of food into the inter-
proximal space, with resulting absorption of the interproximal gimi tissue.
