The Decay of Cementum The inorganic portion of the cementum becomes decalcified by the action of the acid end product of fermentation, and this isfollowed by the Liquefaction of the remaining organic matrix(Figs. 257 and 258). It occurs when the peridental membranehas been detached from the cementum, food becoming lodged inthe pockets so formed. The invasion occurs along Sharpersfibers. CHAPTER XXIIIHYPERCEMENTOSIS General Considerations Hypercementosis, hypertrophy of the cementum (or dental ex-ostosis, as it is sometimes erroneously called) is an increase ofcementum substance which serves no physiologic purpose.
