The conjugate reflectivity of colloidal gold has been measured for four samples containing particles with mean sizes 5, 10, 15, and 30 nm. response times the indicate a size dependence, but signal strength was found to be only weakly dependent on particle size. Calculations local-field enhancement in host matrix by effective-medium theory that nonlinearity is inherent particles.
Background Oral health is important both for well-being and successful elite sporting performance. Reports from Olympic Games have found significant treatment needs; however, few studies examined oral directly. The aim of this study was to evaluate health, the determinants effect on well-being, training performance athletes participating in London 2012 Games. Methods Cross-sectional at dental clinic within Polyclinic athletes’ village. Following informed consent, a standardised history,...
Abstract Objectives To measure dental caries, erosive tooth wear ( ETW ), periodontal health, self‐reported oral health problems and performance impacts in a representative sample of UK elite athletes from different sports using standardized conditions clearly defined clinical indices impact on with evidence validity sport. Methods Cross‐sectional study, single, calibrated examiner, conducted the local facilities professional UCL ethics number 6388/001). Main measures: caries ICDAS BEWE BPE...
Cure, volumetric changes and mechanical properties were assessed for new dental composites containing chlorhexidine (CHX) reactive calcium phosphate-containing (CaP) to reduce recurrent caries.20wt.% of light curable urethane dimethacrylate based liquid was mixed with 80wt.% glass filler 10wt.% CHX 0-40wt.% CaP. Conversion versus depth 20 or 40s exposure by FTIR. Solidification polymerization shrinkage determined using ISO 4049 17304, respectively. Subsequent volume expansion biaxial...
To determine the effects of various monomers on conversion and cytocompatibility dental composites to improve these properties without detrimentally affecting mechanical properties, depth cure shrinkage.Composites containing urethane dimethacrylate (UDMA) or bisphenol A glycidyl methacrylate (Bis-GMA) with poly(propylene glycol) (PPGDMA) triethylene glycol (TEGDMA) were characterized using following techniques: (FTIR at 1 4mm depths), (BS EN ISO 4049:2009 FTIR), shrinkage 17304:2013 strength...
To determine which variables were best related to the overall morbidity of a child undergoing dental general anaesthetic (GA) and then use these those factors that might influence extent severity experienced by healthy children following GA.Data collected on anxiety, pain morbidity, GA procedure from 121 attending day stay unit for treatment. Patients interviewed preoperatively, postoperatively before discharge four further times over next 148 h. Data analysed using multivariate...
Background The few studies that have assessed oral health in professional/elite football suggest poor with minimal data on impact performance. aim of this research was to determine a representative sample professional footballers the UK and investigate possible determinants self-reported well-being, training Methods Clinical examination senior squad players using standard methods outcomes carried out at club facilities. Questionnaire were also collected. 8 teams included, 5 Premier League, 2...
Abstract Objectives Oral and periodontal health have been linked to systemic health, cardiovascular disease inflammation markers. Physical fitness has increased inflammatory response, but only few studies investigated the association between oral with physical activity. The aim of this study was evaluate status in British law enforcement workers. Methods 89 subjects were recruited November December 2019. Cardiopulmonary measured by Maximal Oxygen Uptake (VO 2max ) (ml/kg/min) Maximum Load...
