16 EXTRACTION OF AN UPPER MOLAR. 



effort being made to extract, it slipped into the 

 antrnm. A consultation was at once held with 

 Mr. Stanley, and as the patient's father had died 

 from malignant disease of the lower jaw, it was 

 agreed that the fang should be removed from the 

 antrum on the following day. 



28th. — The soft parts being reflected, the bone 

 in the situation of the stump was removed 

 obliquely by a small trephine. The cavity was 

 carefully explored and injected, but no trace of 

 the missing fang could be discovered. A larger 

 trephine was now used, and the antrum opened 

 in a more depending situation ; but still, after 

 repeated explorations and injections, we failed to 

 extract the object of our search, and Mr. Stanley 

 suggested that it was possible that the stump 

 might have escaped through the opening during 

 the night. Mr. Callender and myself thought 

 we could feel it in a deep fossa, at the posterior 

 part of the antrum ; but ridges of bone, and the 

 fangs of other teeth which projected into the 

 cavity, made the result of the examination very 

 uncertain. 



On the 29th I visited the patient at Edmonton. 

 He stated that he had had some pain during the 

 night, but being now comfortable, he objected to 

 further interference. Being certain, in my own 

 mind, that the fang was not removed, I persuaded 

 him to allow me to inject the cavity, and three 

 pints of warm water were forcibly poured into it
