to evaluate the effect of different light intensities on the degree of conversion (dc) of dual-cured resin cement at different depths of translucent fiber posts.thirty translucent fiber posts were randomly assigned into three (n=10) groups. they were cemented in the simulated canal spaces using duo-link dual-cured resin cement. the cement was light-cured under 600, 800 and 1100 mw/cm(2) light i...

The patient?a Hindu male child aged 4, admitted on 31st October, 1933, for treatment of an ulcer on his head. On examination the following signs were observed; these had apparently escaped the notice of his parents. He had difficulty in swallowing, could only partially open his mouth and his eyes were partly closed, the lower extremities were stiff and abdomen rigid; these signs were detected a...

claim may well be indefensible. The cost of cases of this sort to the medical defence organizations is considerable; the reputation of the surgeon is tarnished; and, most important of all, the patient suffers an avoidable permanent disability. The remedy is simple. Routine x-ray examination of the hips and pelvis should be made before any treatment is given for a sizable injury to a lower limb ...

AIM The aim of the present study was to evaluate these two high intensity light curing units regarding microleakage beneath metal and ceramic brackets. MATERIALS AND METHODS A total of 60 freshly extracted human premolar teeth were randomly divided into four groups of 15 samples; group I: Metal bracket + LED cured, group II: Ceramic bracket + LED cured, group III: Metal bracket + plasma arc c...

The reparability of dual-cured resin composite core buildup materials using a light-cured one following one week or three months storage, prior to repair was evaluated. Two different dual-cured resin composites; Cosmecore™ DC automix and Clearfil™ DC automix core buildup materials and a light-cured nanofilled resin composite; Filtek™ Z350 XT were used. Substrate specimens were prepared (n = 12/...

The present study includes cloning and expression of recombinant Leishmania donovani histone proteins (rLdH2B, rLdH3, rLdH2A and rLdH4), assessment of their immunogenicity in Leishmania infected cured patients/endemic contacts as well as in cured hamsters and finally evaluation of their prophylactic efficacy in hamsters against L. donovani challenge. All recombinant proteins were expressed and ...

PURPOSE This study evaluated the color stability of four stains of a light-cured porcelain stain system between the light-cured and fired stages. MATERIALS AND METHODS Thirty-six ceramometal discs 20 mm in diameter and 2 mm in thickness were cast to provide the substrate on which Ceramco II porcelain was applied. The porcelain was polished to a uniform thickness of 2 mm, and the samples were ...

Purpose: Denture-related stomatitis is probably the most common form of oral candidiasis and its reported prevalence varies widely ranging up to 65%. In this in vitro study, we evaluate the effect of delmopinol application on Candida albicans adherence on heat-cured acrylic resin, cold-cured acrylic resin and microwave-cured acrylic resin. Materials and methods: A total of 40 specimens of each ...

depth of cure of composite material is restricted and it depends on many parameters such as thickness. the aim of this in-vitro study was to evaluate the depth of cure of two light-cured core build-up composites (quixfil and photocore) in different thicknesses, when cured for 60 seconds.the vickers microhardness measurements were made for each side of the top irradiated surfaces of 1,2,3,4,5,6,...
