Arsenous acid, when used in too great quantity forthe devitalization of a tooth pulp, or if not securely sealed in thecavity of decay, may penetrate to the alveolus and produce anecrotic condition that will spread to other tissues. The pericemental inflammations consequent upon the death andinfection of the dental pulp are a fruitful source of necrosis of thealveoli and maxillae. As has been elsewhere asserted, these alwaysinduce an osteitis more or less severe, and when the irritation iscontinuous, as in the case of atonic patients, it may very readilyresult in death of the adjacent bony tissue. The premature fillingof the roots of septic teeth by the dentist has been responsible formany cases of necrosis. The introduction of the filling before the Fig. 54-

Mercury, when given in large doses, may cause it.Tertiary syphilis is quite likely to attack the palate and nasal bones.People who, having dead teeth, work in match factories, are espe-cially liable to a form of affection called phosphor-necrosis, causedby the fumes of the phosphorus used, which is supposed to pene-trate through the root canal, and thus to come in contact with thepericementum which gives nutriment to the alveolar sockets.
