The oxychloride being an in-ferior conductor of heat to metal, there will be less chance ofirritation due to changes of temperature. In almost all caseswhere we have had the opportunity of seeing the result of thistreatment, we have found the pulp alive and apparently healthy,but never calcified. In the place of nitric acid the actual cautery may be em-ployed (Fig. 213), the best form being the galvanic, in which abent platina wire is maintained at a white heat. After de-stroying a portion of the surface of the pulp by the heated wire,we proceed as in the treatment after the application of nitric(icid. We have spoken of hypertrophy of the pulp when exposedby disease. In many cases, especially those of extensive carieson masticating surfaces, the pulp becomes enlarged to severaltimes its own normal dimensions, extending to the level of the TREATMENT OF DENTAL CARIES,Fi£:. 213. 22)Fi?. g The galvanic cautery. The portion held in the hand is constructed of ivory, and Insulates the wires from the battery, which terniiuate I in a loop of fine platina wire : the latter becomes white hot when J the battery is in action. o I crowns of adjoining teeth. It presents ai pale rose color, and is tender when pressedI upon, but not nearly as so as an ordi-I narily exposed pulp; it bleeds freely Avheni touched, and excretes a fluid of most ofl^en-I sive odor, often tainting the breath considera-I bly. A section shows its surface to be cov-I ered with very regularly arranged papillae,but we have not been able to make out anyspecial secreting glands. In most cases theteeth thus aifected are too far destroyed toinduce us to attempt their preservation, but,in cases where it has been considered worthwhile, we have generally by the followingplan succeeded. We first dose the growthwith carbolic acid to deaden its sensitiveness,and then, witi
