TL;DR: Fibrous dysplasia involved the maxilla Seven times and the mandible four times in the eleven cases of this series in which the bone lesion was solitary and in the single polyostotic case the mandibles was the only bone of the skull affected.

TL;DR: The histologic changes apparently do not arise from a single etiological factor, but are a manifestation of the altered nutritional and the metabolic status of the individual during pregnancy, and the immediate cause of the gingival changes appears to be a diminished utilization of estrogen or a modification of estrogen metabolism.

TL;DR: The suggestion that the reaction of the periodontal membrane in the production of the cementoma may be essentially similar to the process resulting in the formation of ossifying fibromas, fibrous ostcomas, and fibrous dysplasia of bone means that it becomes important to place more stress on the histologic analysis of such lesions if an accurate diagnosis is to be forthcoming.

TL;DR: Chronic ankylosis of the temporomandibular joint is discussed from the standpoint of incidence, etiology, pathology, diagnosis, and treatment.

TL;DR: It is proved that this pathological-clinical study proves that the so-called “Turner teeth” result from periapical inflammatory processes of deciduous teeth, which extend toward and affect the buds of the pertinent permanent teeth during their prefunctional stage of eruption.

TL;DR: Eighteen cases of ankylosis of the temporomandibular joint have been analyzed as to cause and symptoms and Condylectomy and osteoarthrotomy are recommended rather than arthroplasty.

TL;DR: The Russell attachment has the advantages of all the other labial attachments, and, in addition, can be handled with less time and effort, and lends itself to various applications with the’greatest efficiency.

TL;DR: The pathologic findings in Groups 2 and 3 support the rationalization that sterilization of the tooth previous to resection is the treatment of choice and reduce the infection and permits the body defenses to localize the inflammatory process and reduce its activity.

TL;DR: No postoperative hemorrhage in any case where Gelfoam and thrombin was employed, and, indeed, bleeding was of a minimal amount, and the useful application of an absorbable hemostatic agent to oral surgery is anticipated.

TL;DR: There is evidence of the inductive influences of one tissue on another in the odontogenic mixed tumors, and it is noted that epithelium in these tumors seems to stimulate dentine formation, but that the presence of epit Helium is not necessary for the production of dentine.

TL;DR: The occurrence of lesions in the mandible and maxilla in this disease would seem to strengthen the growing body of opinion that eosinophilic granuloma of bone is a variant of the disease process which underlies Letterer-Siwe and Hand-Schuller-Christian diseases.

TL;DR: In this paper, the mandibular joint was studied in 79 hypophysectomized female rats at postoperative intervals ranging from 4 to 645 days, and the transformations occurring following hypophysemy are similar to those occurring in aging rats.
