Much discussion has been raised as tothe therapeutic value of this secondarycalcification of the dentin. Perhaps thebest work which has been done upon thissubject is that of Dr. W. D. Miller. Hetakes the position that the calcificationis an effort on the part of the pulp toinhibit the progress of the invading it be the wear of abrasion orthe decalcification of caries or erosion,in any case the attacking force meetswith a tissue which is not open andporous like normal dentin, but is a solidcalcific body, which obviously offers Fig. greater resistance to the invading processin its advance toward the pulp. Thismay be illustrated by a series of micro-photographs selected from the collection BUNTING. SECONDARY CALCIFICATIONS OF THE TOOTII-rULP. 161 of the late Dr. Miller, many of whichwere made by him personally. In Fig. 1 we have a picture of normaldentin at the clento-enamel junction, Ftg. 8.
