Dr. Eisen makes it his practice to radiograph both sides of the mouthon plates first, then re-ray on a film any suspicious areas found in theplate if necessary to get a better view. This practice is certainly to becommended. I have made the statement repeatedly that an im- tafth pacted tooth may cause no trouble at all or it may produce the most disastrous results. Allow me to illustrate this: Figure 458A and 458B show two impacted upper cuspids 4i8 - APPENDIX in the same mouth. One (Fig. 458A) shows no evidence of pathologiccondition of the surrounding tissues while the other (Fig. 458B) showsa great deal of bone destruction, due to suppuration. However, an un-. Fig. 457. The arrow points to a V-shaped area, indicating bone destruction back of a lowerthird molar. (Eisen and Ivy.)
