Medicated Oxyphosphate Fillings.—Dr. Chas. B. Atkinson
claims the following advantages for such filling materials
First.—A remedial agent in constant contact with the walls of
the cavity.
Second.—Germicidal action of the filling on the tissue with
which it comes in contact.
Third.—A neutral influence resisting solution.
Fourth.—Increased hardness, varying somewhat with the agent
used. The medicaments for oxyphosphate fillings are: i.
Creasote and oil of cloves, equal parts ; 2. Eugenol ; 3. Del-
iquesced Carbolic acid ; 4. Oil of cinnamon 5. Oil of cloves ;
;
6. Creasote, pure ; 7. Creasote, oil of cloves and iodoform ;
8. Creolin 9. Campho-phenique ; lO. Potassium chlorate
;
(powdered); 11. Salicylic acid; 12. Camphor (pulverized);
13. Stick sulphur (pulverized); 14. Iodoform; 15. Oil of
wintergreen. The first seven have been fairly tested by Dr. At-
kinson and were found to be equal in durability, manipulative
qualities and time of setting. He employs them also in retaining
inlays, in setting retaining-fixtures in pyorrhoea cases, in setting
crowns, etc. In capping pulps he always employs a mixture of
oxide of zinc, creasote and oil of cloves, and adds a remedial
agent to the oxyphosphate filling. He employs mostly the first
named on the list. If the medicament is a liquid he adds about
an equal quantity of the medicament and phosphoric acid ; if a
powder, about equal parts of the medicament and oxide. The
proportions may be varied as required. The average time of set-
ting is about ten minutes.
