Toothpastes arguably are the most common preparations used in the treatment of dentine hypersensitivity. Evidence for efficacy largely comes from clinical trials, and supports the role of the contained so-called "active" ingredient. How such compounds produce therapeutic benefit has received limited attention. This study measured the availability and uptake(More)
Dentine has been shown to possess affinity for a large number of varied compounds, many of which have been shown effective in clinical trials, for the treatment of dentine hypersensitivity. The mode of action of these compounds is unclear. The aim of this study was to investigate the uptake of metal ions, fluoride and formaldehyde in solution onto dentine(More)
— In this paper the implementation of a low power high speed 4-bit Binary Search ADC (BS-ADC) is reported using 180 nm CMOS technology. The concept of Threshold Modified Comparator Circuit (TMCC) is introduced as a modification of the latch-based conventional comparators. The reported structure of the ADC occupies an active area of 0.0157 mm 2 and consumes(More)
Two hundred and one patients had unilateral removal of the lower third molars under local anaesthesia and a further 234 patients had either bilateral or unilateral removal under general anaesthesia. A total of 634 lower third molars were extracted by four experienced surgeons (two consultants and two senior grade staff). All patients were reviewed(More)
OBJECTIVES To determine the incidence of ECG abnormalities in a healthy adults undergoing a surgical extraction of third molar teeth pre-and post-operatively and to study the effect of local anaesthetics, surgical stress and analgesics on cardiac rhythm. METHOD One hundred and ninety-eight healthy adult patients taking part in a clinical trial of(More)
During a study to assess the efficacy of five toothpastes in the treatment of dentin hypersensitivity, the plaque scores of patients were recorded at baseline, 2, 4, and 6 weeks treatment and 6 weeks post-treatment visits. Baseline buccal and lingual plaque indexes were found comparable between the groups and the mean buccal plaque scores were considered(More)
