. The science and practice of dental surgery. Fig. 957.—Ipper LateralIncisor. Kesult of absorbed. In the case shown in Fig. 958 it was foundimpossible to remove the third molar, but thiswas effected without undue injury to thesurrounding parts after a radiograj)h had beenobtained. The mandible was very shallow andweak. It not infrequently happens that in takingradiographs for other purposes, an unsuspectedthird molar is found. Another condition in which the X-rays aremost useful to the dental surgeon is that of. Fig. 95S. —Case uf difficult extraction of Third Mandi-bular Molar. Mandible is unusually shallow andhaa a large inferior alveolar canal. a supernumerary tooth in the palate, or otherteeth much misplaced, e. g. a premolar orcanine luider the tongue, etc. Possibly onlya point of the tooth can be seen or felt with aprobe, which does not reveal the direction andlength of the root—ob\iously a most importantparticular. In fact, it might be legally arguedin such cases of obvious difficulty, that if adental surgeon failed to avail himself of theX-rays before attempting extraction, blamemight be attached to him for unfortunateresults caused by conditions that the X-rayswould have revealed. Additional roots, obstruction by an uneruptedtooth, unusual size and shape of roots, etc.,are other causes that can be revealed. Films or plates must be chosen according toposition and other circumstances. Periodontal Disease All authorities on the study of disease involv-ing the peridontal membrane, ar
