Primary malignant melanoma of the oral cavity. Report of an unusual case

A case is reported of a malignant melanoma in the mouth of a 74 year old male, which was originally diagnosed as reactive denture hyperplasia caused by a ill-fitting upper denture.

Fibrous dysplasia of the jaw bone: A review of 15 new cases and two cases of recurrence in Jamaica together with a case report
The authors reviewed 15 new cases of fibrous dysplasia of the jaw bone and two cases of recurrence seen in Jamaica between 1980 and 1995. Only cases which had a histological confirmation of fibrous dysplasia were included. The clinical behaviour and radiological findings of these cases were studied from the case files, either at the Cornwall Regional Hospital or the Kingston Public Hospital in Jamaica.

Root morphology of the maxillary first premolar in Singaporeans
Extracted teeth were collected from clinical procedures performed in the Faculty of Dentistry, National University of Singapore. A selected sample of 957 maxillary first premolars were subjected to visual examination and digital radiography. There was a higher incidence of two-root form (50.6 per cent) than previously reported for the Singaporean dentition.

Service-mix in general dental practice in Japan: A survey in a suburban area
Overseas investigations have reported the amount and variety of dental services provided. An understanding of the current service-mix in private general practice is important in the anticipation of the future practice of dentistry. The main purpose of this study was to describe the service-mix of private general practitioners in Japan, which was recorded using the Australian Dental Association Dental Procedure Code.

Determination of gold alloy loss during the production of cast dental restorations
Values for the loss of high gold content dental alloy during the fabrication of three types of cast dental restorations were determined. The mass changes measured were for the melting, casting and cleaning processes and the docking and laboratory finishing procedures involved in producing the final restoration. The casting yield from the alloy cast was also determined.

Abnormally high fluoride levels in commercial preparations of 40 per cent silver fluoride solution: Contraindications for use in children
Although a 40 per cent solution of silver fluoride would be expected to contain 6 per cent fluoride (60 000 ppm), F- levels of 100 000 ppm and 120 000 ppm were found in 14 commercial samples analysed at The University of Western Australia in 1993 and 1994. To determine whether F- levels in 40 per cent AgF preparations have remained high, the present investigation was aimed at analysing different batches of commercial preparations obtained more recently.

Polyvinyl siloxane impression materials: An update on clinical use
Polyvinyl siloxane impression materials have applications in a variety of indirect procedures in prosthodontics and restorative dentistry. Favourable handling properties, good patient acceptance and excellent physical properties have resulted in their popularity in today’s practice. In this review, the chemistry and important physical properties of polyvinyl siloxanes are summarized, and recent clinical questions of improved hydrophilics, tray adhesives, disinfection, and glove-induced polymerization inhibition are addressed.
