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)
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)
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 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)
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)
Effective undergraduate teaching of gerodontology to present and future dental students is important if good oral health care of older people is to be assured. A review of the undergraduate curriculum for gerodontology is presented and indicates the need for a knowledge base from which new graduates can develop a special interest in care of older patients.(More)
Electromyographic recordings (EMGs) were made from the active masseter muscle of the inhibitory reflex evoked by application of electrical stimuli to the skin of the upper lip in 11 human subjects. In control sequences, the reflex had a mean latency and duration of 41 +/- 1.7 and 44 +/- 2.6 ms, respectively. The magnitude of the reflex (measured by(More)
