BACKGROUND To determine if a novel dual camera imaging system employing both polarized white light (PWL) and quantitative light induced fluorescence imaging (QLF) is appropriate for measuring enamel fluorosis in an epidemiological setting. The use of remote and objective scoring systems is of importance in fluorosis assessments due to the potential risk of(More)
Quantitative Light-induced Fluorescence (QLF) has been used to measure tooth stain in vitro; however the current analysis method cannot be used in vivo, as it requires regions of interest to be surrounded by unstained tissue. In this study, an algorithm was developed to detect stain on QLF images of teeth captured in vivo. It uses convex hulls to(More)
BACKGROUND The purpose of this study was to compare diagnostic performance for the detection of caries using photographs with an established visual examination method and histological sections as the reference standard. METHODS 50 extracted permanent teeth were assessed for the presence of occlusal caries by 9 examiners using two methods; traditional(More)
BACKGROUND Tooth decay is the commonest disease of childhood. We have known for over 90 years that fluoride can prevent tooth decay; it is present in nearly all toothpastes and can be provided in mouthwashes, gels and varnishes. The oldest method of applying fluoride is via the water supply at a concentration of 1 part per million. The two most important(More)
BACKGROUND Untreated caries in young children can result in a referral for extraction in hospital under general anaesthetic (GA). This study aims to explore the impact of caries during the ensuing wait for GA on children resident in the North West of England. METHODS The study involved 456 respondents referred to six hospitals in the Northwest of England.(More)
BACKGROUND This paper is a summary document of the Prevention in Practice Conference and Special Supplement of BMC Oral Health. It represents the consensus view of the presenters and captures the questions, comments and suggestions of the assembled audience. METHODS Using the prepared manuscripts for the conference, collected materials from scribes during(More)
It is with great pleasure that we present, on behalf of the authors, the manuscripts from the Prevention in Practice Conference held in Cape Town, South Africa, in June 2014. The purpose of the conference was to bring together key opinion leaders in prevention, service design and organization, public health and health economics to discuss the possibilities(More)
BACKGROUND The quantification of fluorosis using fluorescence imaging (QLF) hardware and stain analysis software has been demonstrated in selected populations with good correlation between fluorescent image metrics and TF Index scores from photographs. The aim of this study was to evaluate the ability of QLF to quantify fluorosis in a population of subjects(More)
BACKGROUND The standard measurement of oral conditions that are mainly of cosmetic concern can be carried out by a trained clinical professional, or they can be assessed and reported by the individuals who may have the condition or be aware of others who have it. Enamel opacities of anterior teeth are examples of such a condition. At a public health level(More)
