Likewise, if the reflexes arecaused by an alveolar abscess, its presence can bethereby determined. Where pulp stones are producing the trouble, they canoften be detected, if intense care is exercised in makingthe radiograms. If these reflexes are the result of hid-den caries, the radiogram will frequently suggest the INDICATIONS FOR X-RAY IN DENTISTRY 167 presence of such a condition, providing the cavities occurupon the mesio-or disto-approximal surfaces of the teeth,and are sufficiently extensive so that the density of thetooth structure in the region of the cavity is decreased,or the contour of the tooth is altered.
