PURPOSE To determine the risk factors for recurrence of giant cell tumours (GCTs) of bone. METHODS Medical records of 29 men and 29 women (mean age, 34 years) treated for primary (n=53) or recurrent (n=5) GCTs of bone and followed up for a mean of 40.2 months were reviewed. The tumours were located in the distal femur (n=18), proximal tibia (n=10), proximal femur (n=8), distal radius (n=7), p...

AIMS Intralesional treatment of giant cell tumour (GCT) of the bone may result in a high rate of local recurrence. The introduction of local adjuvant therapy, such as cementation or phenolization, has lead to a significant reduction in recurrence rates. Due to the combined use of phenol and cementation in most studies, the effect of phenol alone is described in this study. METHODS Twenty prim...

Resin cements are often used for single crown cementation due to their physical properties. Self-adhesive resin cements gained widespread due to their simplified technique compared to regular resin cement. However, there is lacking clinical evidence about the long-term behavior of this material. The aim of this prospective clinical trial was to assess the survival rates of metal-ceramic crowns ...

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...

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...
