38 PYORRHOEA ALVEOLARIS. to better advantage or at least to greater satisfaction after the douching with hot water, as the foaming makes a much pret- tier display where everything has been thoroughly cleansed previously ; the fact is that it is not an indicator of pus, and that the greater the proportion of pus present the less foaming activity of the pyrozone. After the thorough washing out of the " pocket " at the beginning of the secondary treatment, the next step is to treat the case with a ten per cent, solution of nitrate of silver, which should be made to permeate every possible part of the pus cavity. NOTES ON NITRATE OF SILVER. Nitrate of silver should be applied with a quill device (pre- viously described) wherever practicable. It is true that the solution can be better applied with a syringe, but it is highly it fouls destructive to the metal of which syringes are made ; rubber syringes in a most peculiar manner and renders them useless very soon. It is expensive to have syringes constantly damaged and maybe ruined by medicinal agents, but the den- tist who essays to succeed with this method of treating pyor- rhoea alveolaris must not expect to do so too economically. If, in a given case, it appears necessary to inject this solution of nitrate of silver into a " pocket " in order to attain success, there should be no hesitation at the cost of an ordinary dental syringe. After applying the nitrate of silver solution, it is well that the case be protecteclagaih^ saliva for a minute or two. / \ • • • • • • • • • *• •* • « • • ' * • •• * * • * «««« * « •• « *
