Not illustrated. 1881 Excerpt: ...may, as we shall see, be turned to good account in certain troublesome cases. To resume: the fang-cavities being cleared out, --no easy matter in the case of lower molars, --they should be filled up, and, though gold may be employed in certain easy cases, it is better to use the oxychloride of zinc, mixed rather fluid, and incorporated with finely-chopped cotton wool; this must be worked into the fangs by a sort of pumping action, by which means the air is pressed out and the stopping pressed in; the oxychloride being powerfully antiseptic, little hurt is likely to accrue if any small particles of soft tissue b3 left in the fang cavities. If gold be used, it is well to wash out the fang-cavities with carbolic acid or creosote before attempting to insert it. Occasionally, though rarely, and more especially in singlefang teeth, we may find that the pulp has undergone a species of dry gangrene, and on removal appears free from unpleasantness, and of a pithy consistency; the tooth has not changed colour, and the periodontal membrane appears perfectly healthy, showing that the tooth, though possessing no vitality except probably at its cementum, is no cause of irritation to surrounding tissues. In other cases we may find that the whole of the dental pulp has sloughed away, leaving the surrounding dentine softened, but not putrid, both of which classes of caises we should treat precisely as if we had removed the pulp. It may, however, happen that, whilst the pulp has sloughed away, the canal-cavitie3 are filled with puriform fluids, the dentine itself being moist and very offensive; and it is rare to find, in such cases, freedom from periodontal irritation, caused no doubt by the presence of septic substance. Such cases have been usually treated by the frequent app.
