Diseases of the soft structures of the teeth and their treatment; a text-book for students and practitioners . refore, it may not be amiss to give as a preamble the definitesignificance of the more important terms as they are used to desig-nate the specific nature of their action. It is generally recog-nized at present that the breaking down of highly organized bodies13 1111 DISEASES OF THE DENTAL PULP is brought aboul by the activity of minute vegetable organismsthe bacteria. This process is known as putrefaction, or, undercertain conditions, as fermentation. The presence ol certainbacteria and their products is Instrumental in the production ofsevere physiologic changes resulting in the various \ ital phenomenaknown as infectious diseases. The existence of a condition inwhich bacteria] infection and its sequels are brought about by thepresence of germs or their products is referred to as sepsis, while asepsis implies the entire freedom From such infection. If a pri-marily septic condition is changed by some method or means whichinhibits the growth of tIk* putrefactive organism, antisepsis is. icj. 101. Aseptic medicament tray induced. Antiseptics, Therefore, are chemical agents which merely inhibit the action and growth of bacteria, while germicides destroythe vitality of the infective organisms. Disinfectants also kill thebacteria, and incidentally chemically change their poisonous pro-ducts to some inert compound. A disinfectant must, therefore, bea germicide, while an antiseptic is not necessarily a germicide nor;i disinfectant. According to Dakin and Dunham, the action of chlorin uponbacteria and their products seems to depend upon a process ofchlorination, i. the amino-acid group of the proteins readily ii Iit- < NCI
