But such a condition is not that which has usually been denomi-nated alveolar abscess. The common acceptation of the term is thataffection which is the result of inflammation and death of thepulp, its infection, and the consequent inflammation and infectionof the pericementum from contiguity of tissue. If we take upthe subject of the last chapter at the point of its closure, andsuppose the pulp of a tooth to be devitalized as the result of stasisof the blood currents, with the consequent stoppage of all nutritionthrough a distinctive inflammation, the next inquiry will beconcerning the final disposition of the devitalized pulp. Fig. Metastatic Abscess. Mass of staphylococci in the center, surrounded by an area of coagulation necrosis, thewhole inclosed by a cordon of leucocytes. (Kirk.) If there is no source through which it can become infectedwith micro-organisms, it will probably become mummified anddesiccated; the moisture will be absorbed from it, and it willassume the condition of dry gangrene, in which it will remain foran indefinite period without being the cause of any irritation what-ever. If, however, such a pulp chamber be opened without thestrictest antiseptic precautions, perhaps years after the death of ALVEOLAR ABSCESS. 121 its contents, germs of infection may be carried in upon the non-sterilized instruments or admitted with a particle of saliva, andseptic inflammation, with perhaps consequent alvoolar abscess, willbe the result. The infection may arise from either one of
