Some applications of salivary gland scintigraphy.

Some of the uses of technetium 99 pertechnetate in salivary gland investigation are shown. By means of a gamma camera, which records dynamic studies, normal salivary physiology is investigated and also various forms of salivary gland pathology. The use of salivary scintigraphy in evaluation of the end results of parotid duct repositioning is discussed. This does not appear to have been reported previously.

The frontal screw; a fixed point for internal suspension.

The use of a screw in the frontal bone to provide a fixed point for internal suspension is described. This technique has advantages over other forms of internal suspension and is particularly useful in cases of severe trauma, where the more conventional fixed points may not be available.

Tumours of the salivary glands: a histological and clinical review.

The aim of this paper is to try to identify points of correlation between the histological appearance and the clinical behaviour of minor salivary gland tumours. To this end 62 well-documented minor salivary gland tumours have been followed up for at least five years or until recurrence. The discussion is limited to the adenoidcystic carcinoma, the pleomorphic adenoma and the basal cell adenoma, since only these three tumours were represented in sufficient numbers to be analysed. For each tumour a number of histological pointers to prognosis are reviewed. In the case of the basal cell adenoma, a recently recognised tumour, the possibility of confusion with the adenoidcystic carcinoma is discussed.

Acute leukemia. An atypical case presenting with gingival manifestations.

A case of acute myeloblastic leukemia is reported in which the mode of presentation was an atypical gingival lesion. A definite diagnosis was not made until the patient was in a final stage due to non-diagnostic histologic material. One must be suspicious of any gingival lesion, particulary if there is a sudden onset of bleeding or hyperplasia. Leukemia must be considered even if initial investigations are negative, as in the case presented.

Thrombocythemia as a cause of oral hemorrhage.

Thrombocythemia is characterized by an increase in platelet numbers coupled with abnormal function. Three cases diagnosed after referral to an oral surgeon are presented. In each case the reason for referral concerned excessive dental hemorrhage. Thrombocythemia should be included in the differential diagnosis in cases of oral hemorrhage.

The great amalgam debate.

Mercury amalgam has been used for dental fillings since the 1830s. Over that time, questions have occasionally been raised with regard to its safety, but a recent TV programme in America has re-focussed attention in this area.

Maxillary sinus complications related to endosseous implants.

There have been many expanded applications for the use of endosseous implants in the reconstruction of partially and totally edentulous patients. The posterior maxilla, which frequently has inadequate quality and quantity of bone, and the contiguous maxillary sinus often provide poor recipient sites for endosseous implants. However, innovative procedures using autogenous, allogeneic, and alloplastic graft materials have enabled clinicians to place implants in the reconstructed resorbed maxilla. These techniques often violate the anatomic integrity and interfere with the physiologic mechanisms of the maxillary sinus, creating potential complications. Eight patients with complications following maxillary sinus augmentation and reconstruction with endosseous implants are reported.
