The role of computed tomography in the evaluation of cemento-osseous lesions.
The role of computed tomography (CT) and CT numbers in the evaluation of fibro-osseous and cementum-containing lesions is discussed. The computed tomographic findings in a case of cemento-ossifying fibroma involving the maxilla and maxillary sinus are presented.
An unusual cause of facial trismus in a child: report of case.
Nasopharyngeal carcinoma should be considered in the differential diagnosis of facial pain, especially in patients of Asian descent. The foregoing case describes an unusual cause of a symptom often associated with temporomandibular joint dysfunction. It also emphasizes the need to eliminate an underlying neoplastic process when dealing with patients who have temporomandibular joint dysfunction or who have atypical facial pain. Malignancies of the temporomandibular joint and the periarticular area, although rare, do occur. This case shows the usefulness of computed tomography in the evaluation of a patient with temporomandibular joint dysfunction.

Collagen gel in osseous defects. A preliminary study.
In a preliminary study, the effects of a biodegradable collagen gel on the healing of osseous defects were examined. Histologic and biochemical observations made on the seventh day after placement revealed that the collagen gel is well tolerated by the recipient and might be an effective stimulator of the formation of reparative bone. However, between the seventh and fourteenth days after placement, the deposition of reparative osseous tissues at the site of implant was significantly retarded. The possible implication of these findings is discussed.
The effects of thermal and electrical injury on pulpal histamine levels.
The present investigation was undertaken to determine possible quantitative changes in porcine pulpal histamine levels following thermal and electrical insult. Quantitative spectrophotofluorometric assays revealed a fourfold increase in pulpal histamine levels within 30 minutes of thermal injury. These findings suggest that histamine may play a role in the initial stages of pulpal inflammation. Electrical insult was found to have no significant effect on pulpal histamine contents 30 minutes after insult. The possible implications of these findings are discussed.

The effects of thermal injury on pulpal hydrolases.
The effects of thermal injury on pulpal protein levels and the activities of selected pulpal hydrolases were determined 48 hours following injury. At this time protein levels were significantly greater while enzyme activities were significantly lower in thermally insulted teeth. The implications of these studies are discussed.
Aneurysm of intrapetrous carotid artery: CT and angiographic findings.
Congenital aneurysms of the petrous segment of the internal carotid artery are rare. We report the CT, digital subtraction, and routine arteriographic findings in a case.
