. Elementary and dental radiography / by Howard Riley Raper . wever, I believe I am conservative whenI make this statement: If a tooth, showing bone involvement at its apex,is to be treated through the pulp canal, the canal must be open throughthe end; it must be filled just to, or through, the end, and post-operative 400 . IP FEND IX radiographs must be made at intervals of two or three months for abouta year, or until the abscess cavity is filled with new bone. An abscesscavity which shows no constructive bone change at all at the end of sixmonths after treatment is very probably still a source of infection. Asa generality, it may be stated that if new bone ever will be built into anabscess cavity, some reconstruction will take place within the first sixmonths or sooner, and the reconstructive change will be practically com-plete in about a year. What should be done with teeth, the canals of which are not wellfilled but which show radiographically no bone involvement at theirapices? is a most disturbing question. The idealists answer would Fig. 450. Cement fillings. insert perfect canal fillings or extract the teeth. This advice may not, be good. The question is debatable, with everything infavor of the idealist, however. But certainly, when a patient is veryseriously ill with some disease which might be attributed to a focus ofinfection, all of the pulpless teeth in such a patients mouth should, atleast, have a well-filled canal or they should be extracted. It is not idealistic, perhaps, but it is practical, to bePatrf dYo?03 governed in the treatment of infected teeth by the patients physical condition. When the physical con-dition is good, more conservative treatment can be given the teeth. Whenthe physical condition is bad and the patient is suffering from somedisease which may be attributed to mouth infection, more radical treat-ment (freer surgical interference) must be given for mouth infection.
