Introduction A frictional fitting crown is in intimate contact with the tooth whereas a passive fitting crown has more spaces and does not resist a vertical withdrawing force. The space between the tooth and the crown has been termed the precementation space.' lt is the size of this precementation space and the technique of creating iP5 that greatly influence the seating of a crown during cemen...

INTRODUCTION Mechanical alignment deviation after total knee arthroplasty is a major reason for early loosening of the prosthesis. Achieving optimum cement penetration during fixation of the femoral and tibial component is an essential step in performing a successful total knee arthroplasty. Bone cement is used to solidify the bone and prosthesis. Thickness imbalance of bone cement leads to the...

Informal lending and savings institutions exist around the world, and often include regular door-to-door deposit collection of cash. Some banks have adopted similar services in order to expand access to banking services in areas that lack physical branches. Using a randomized control trial, we investigate determinants of participation in a deposit collection service and evaluate the impact of o...

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...
