The fillingin the distal of the second molar and the filling in themesial of the third molar both hang into the interproxi-mal space causing irritation, inflammation, and osteo-clasia. Fig. 66. The radiolucent spots at the apices of thecuspid and the second bicuspid are of about the same sizeand almost the same general appearance. The spot at theapex of the second bicuspid I believe to be osteoclasiaand odontoclasia, due to infection, in short a spot due toa pathologic process, while the spot at the apex of thecuspid is plwsiologic; that is to say, it does not representdisease. The fact that the cuspid responds positively (+)to the electric test is very strong, I might almo
