As a general rule, favorable; the results depending largely upon the skill with which the indicated therapeutics is applied. The less extensive the process in a denture, and the less deep its invasion in individual teeth, the better is the prognosis. Therapeutics Of Caries. 1. What is the therapeutics of dental caries? The general therapeutics is the removal of the infected material and the unsupported enamel walls, and their replacement by materials, insoluble in the fluids of the mouth, which shall serve to restore the lost form of the tooth, seal the cavity hermetically, and sustain the stress of mastication. 2. Is it necessary to remove all of the infected dentine? Not always; but the greater amount, at least all evidently softened portions, should be removed, and the walls subjected to contact of germicides which shall serve to sterilize the infected portions of dentine which have not been removed. 3. Why is this invaded structure suffered to remain? Exquisite hypersensitivity of the dentine may prevent or render inadvisable thorough excavation; it is quite possible to perfectly sterilize the infected tissue, and it serves as a non-conducting protective covering to the dental pulp. 4. What is the importance of the non-conducting layer? The dental pulp is singularly intolerant of stimuli due to thermal changes. A pulp habitually receiving such stimuli becomes the seat of structural changes, frequently of nodular deposits in its substance, or, it may be, entire calcification about the tissues of the pulp. 5. What are the degrees of caries, and why is this distinction of degrees made? Superficial, deep-seated, and complicated; each...
