In this event, he makes a complete removal of amaxilla or half of the mandible. After the operation iscomplete and the tumor is incised, a tooth is found in thecenter. Had the true condition been suspected, the tumorwould have been removed, such abnormal process of the 256 TUMORS OF THE TEETH bone as was found would have been chiseled away, and in afew weeks repair would have followed without deformityor destruction of functional usefulness of the parts. Differential diagnosis must be made from tooth andbone cysts, osteoma, exostosis, sarcoma, carcinoma, actino-mycosis, and the swellings associated with chronic bonediseases, such as syphilitic gumma and Fig. 79.—Multiple Ctst of Mandible Caused by the Impaction op TwoTeeth Resting at Right Angles to Each Other. Treatment.—The treatment of the simple variety is ob-vious and efficacious, namely, to incise the cyst as early andas thoroughly as possible, remove the impacted rudiment-ary or fully grown tooth, scrape away the epithelial lining,and pack the cavity with suitable material.
