INTRODUCTION Giant cell tumour (GCT) is a distinct neoplasm of undifferentiated cells. The exact cell of origin is unknown. The multinucleated giant cells present are formed from the fusion of mononuclear cells. Giant cell tumour is more common in Southeast Asia than in the West. The incidence is about 20% compared to 4% to 5% in the West. MATERIALS AND METHODS Sixteen patients with giant cel...

The aim of this study was to evaluate the effect of the timing of pick-ups of retentive attachments on locator overdenture post retention. Forty-eight acrylic resin models of edentulous mandibles were prepared. A post space with a depth of 6 mm was drilled into 96 extracted, single-rooted teeth. In each model, two prepared roots were mounted in the canine position with 22 mm between them. The m...

In recent years, oil spills and leakages have often occurred during exploration, transportation, handling, usage, processing, causing serious global environmental problems. Microbially-induced carbonate precipitation (MICP) is an emerging green, environmentally friendly, sustainable technology that has proven to be a promising alternative for soil stabilisation. This paper provides comparison b...

BACKGROUND Currently the standard femoral cementing technique requires cement injection gun to deliver bone cement into the femoral canal. The standard cement gun is expensive and must be imported. There is no previous study about the use of a household caulking gun for femoral cementation. OBJECTIVE To compare the radiographic quality of cementing technique in proximal femur between using st...

OBJECTIVES The hypothesis tested was that processing, pre-cementation and cementation techniques can modify the profilometrically measured deformation of a ceramic. METHODS Three-point flexural moduli of a resin-cement were characterised following light irradiation at 430 and 180 mW cm⁻². Thirty IPS e.max Ceram discs were prepared and a reference surface produced by polishing. Discs were anne...

The need for treatment of dilute metal contaminated water as a residual from mining and mineral processing facilities is ubiquitous. Electrochemical technologies have the potential to provide selective and measurable recovery of base metals from dilute mining influenced water. However, the technology is currently not widely used in the treatment of mining influenced water (MIW). The principles ...

The major drawback of cement-retained restorations is the extrusion of the excess cement into the peri-implant sulcus, with subsequent complications. Insufficient removal of the excess cement may initiate a local inflammatory process, which may lead to implant failure. This article presents a method of controlling cement flow on implant abutments, minimizing the excess cement around implant-ret...

We have studied the processes leading to the cementation of colloidal particles during their autonomous assembly on corroding copper electrodes within a Cu-Au galvanic microreactor. We determined the onset of particle immobilization through particle tracking, monitored the dissolution of copper as well as the deposition of insoluble products of the corrosion reactions in situ, and showed that p...

OBJECTIVE The aim of this study was to evaluate the pulp response following cementation of inlays using two different resin cements. METHODS Deep Class V cavities were prepared on the buccal surface of 34 sound human premolars. Impressions were taken and inlays were prepared which were cemented with the following luting materials-Group 1: Rely X Unicem (3M ESPE); Group 2: Variolink II (Ivocla...
