Principles and practice of operative dentistry . d then,and if the bowels are overactive, a grain of Dovers powder at bedtime isoften of great service. If there is vomiting and flatulence, some carmina-tive will be necessary. In cases where there is much restlessness and dis-turbance of the nervous system, bromide and iodide of potassium with salvolatile will often abate sickness and relieve head-symptoms if present. Local Treatment.—In those cases in which the gums are considerablycongested and swollen, causing pain on pressure, and accompanied with gen-eral febrile symptoms, vomiting, diarrhoea, or cough, almost immediaterelief is often obtained by the free use of the gum-lancet. To be effectivethe lancet must reach the tooth. The incision for the six anterior teeth ofeach jaw should follow the line of the morsal or the cutting edge of eachtooth, except in the cuspids when the cusp has penetrated the gum (), when the incision may be made as shown in Fig. 217, while for the Fig. 216. Fig. 217. Fig. 218. Fig. 219. Fig. molars crucial incisions should be made, one from the disto-lingnal cuspto the mesio-buccal, the other from the disto-buccal cusp to the mesio-lingual (Fig. 218.) These incisions follow the line of the cutting edge in the six anteriorteeth, and cut directly across the cusps of the molar teeth which are nearestthe surface of the gum (Fig. 219), and for that reason are to be preferredto those which are made upon the lines of the sulci between the cusps, asshown in Fig. 220. The indiscriminate use of the gum-lancet, however, should be depre-cated. Much harm has often been done by a thoughtless or empirical useof this valuable means of treatment, while, upon the other hand, manylives have been saved by an intelligent use of it. Many writers and physicians of experience have claimed that its use isnever indicated, and when used it is productive of more harm than good. 72 OPERATIVE DENTISTRY.
