ON DENTAL EXOSTOSIS. 47 



follow from the presence of an additional substance ; 

 and it is first enlarged to make room for the so- 

 called masses of " coagulated lymph," and afterwards 

 remains permanently so for the exostosis formed. 

 It is generally loose and cancellous in structure ; but 

 where the inflammation has long subsided, and the 

 whole of the effused products have been ossified, we 

 find it closely applied to the surface of the fang, 

 and of a p^eternaturally smooth, even, and dense 

 texture opposite the seat of exostosis. 



As a practical corollary to the foregoing patho- 

 logical observations, I would submit that the follow- 

 ing are the indications of treatment in a case of sus- 

 pected exostosis : — First, to remove all source of irri- 

 tation, — the smallest speck of caries should receive 

 due attention and treatment, and any undue pres- 

 sure upon the tooth, especially during mastication, 

 should be avoided and remedied ; and secondly, to 

 reduce inflammation by frequent topical depletion.
