The effect of exposure time of a visible light source on the depth of polymerization and degree of hardness of a sample of Occlusin posterior composite resin was investigated. The border between cured and non-cured composite resin was identified by a change in colour and by applying pressure with a scalpel. Knoop hardness tests were performed perpendicular(More)
Thirty-seven patients wearing complete dentures were investigated for Candida albicans. Twenty-five of the patients suffered from denture stomatitis and twelve had clinically normal mucosa. Candida albicans was isolated and identified from Sabouraud dextrose agar culture medium models constructed from impressions of the maxilla and from the upper dentures.(More)
Denture-induced changes of the oral mucosa comprise, besides denture stomatitis and inflammatory papillary hyperplasia, the so called folds and redundancies in sulci and flabby ridges. The present article deals with these two tissue reactions which are associated with chronically ill-fitting dentures.
Three clinical methods for testing marginal fit of complete cast crowns were investigated: the exploration, radiograph, and impression techniques. This work proved that the impression technique is the superior test and should become a standard part of the evaluation routine for complete cast crowns.
The authors discuss the user programming model for the scalable processor architecture (SPARC) and the optimizing compilers for the SPARC-based Sun-4 workstations. They are concerned with two broad areas: how the compilers use the architecture and the design of the compilers themselves. They discuss the registers, synthesized instructions, tagged data(More)
Provision of complete dentures to a new denture wearer increases the salivary flow rate is well known. The new dentures act as an additional mechanical stimulus to the salivary reflexes, thus increasing the flow rate. The purpose of this study was to determine whether replacing complete dentures would elicit the same response. Unstimulated and stimulated(More)
