OBJECTIVES To compare patterns of admission to hospital and prognosis in white and South Asian patients newly admitted with heart failure, and to evaluate the effect of personal characteristics and comorbidity on outcome. DESIGN Historical cohort study. SETTING UK district health authority (population 960,000). PARTICIPANTS 5789 consecutive patients(More)
The effects on activity in the masseter muscle of applying electrical stimuli to discrete areas within the mouth or on peri-oral skin were studied electromyographically in 8 subjects. In all subjects, the intra-oral stimuli produced two phases of depressed masseteric activity with mean latencies of 14 ms and 47 ms. By contrast, this shorter latency response(More)
PURPOSE The present study investigated the residual functional constraints as well as the psychosocial rehabilitation of tumor patients following prosthetic treatment with implant-supported dentures. MATERIALS AND METHODS A clinical examination and semistructured interview were performed in 66 of 132 consecutive patients who underwent tumor resection and(More)
It has been suggested that incomplete or faulty processing leading to a high level of residual monomer is a factor in denture whitening. Laboratory tests which simulate the cleaning procedures used by patients presenting with whitened dentures have been carried out on specimen strips of acrylic denture base material with high or low levels of residual(More)
INTRODUCTION The objective structured clinical examination (OSCE) is now an accepted tool in the assessment of clinical skills in dentistry. There are however no strict or limiting guidelines on the types of scenario that are used in the OSCE examinations and experience and experimentation will inevitably result in the refinement of the OSCE as a tool for(More)
With the introduction of acrylic resin denture base materials to the dental profession, radiolucency was recognized as a significant deficiency at an early stage. Continuous research into the production of a radiopaque material has been directed at including radiopaque glasses, salts or metals powders in an otherwise radiolucent polymer. However, the(More)
The effects of ageing and dental state on the cross-sectional area and density of two jaw muscles, the masseter and medial pterygoid, were investigated using computed tomography. The study involved 84 male and 70 female subjects between the ages of 20 and 90 years. The cross-sectional area of both muscles showed a significant reduction with age; values for(More)
The effect of ageing on the contractile properties of the first dorsal interosseous muscle was investigated. A group of 42 healthy male subjects between the ages of 10 and 80 years took part in the study. The time to peak tension was significantly prolonged with increasing age but no evidence was found of an extension of the half relaxation time. When left(More)
