Uptake of cadmium into molar enamel and dentin from rats receiving cadmium in their drinking water was markedly elevated and proportional to the amount of cadmium in the drinking water. Post-developmental cadmium did not influence caries development or alter the cariostatic effectiveness of fluoridated drinking water. The data indicate that the absolute concentration of cadmium in teeth is not ...

OBJECTIVES To compare film, desktop monitor and laptop displays of digitized film images for accuracy of caries detection. METHODS Sixty-four extracted teeth were mounted in eight models and radiographed with E-speed bitewing film. Films were digitized and displayed on a desktop monitor and a laptop display. Six observers scored the presence or absence of enamel and dentinal caries for each p...

Traditionally, testing for whether pit-and-fissure caries should be restored involved probing with a sharp explorer and evaluating resistance to withdrawal (ie, "stick"). Alternative visual methods of evaluation and classification have been proposed, validated, and accepted formally in the core curriculum on caries management in both Europe and North America. This article examines the resistanc...

The present study aimed at assesssing – by clinical, histological and radiological investigations – the influence of some external factors on the pulp-dentin complex, and at providing a causal interpretation of the structural changes observed. Materials and methods. Clinical and radiological exams were performed on 65 old patients with ages between 60-75, and also on 40 young patients with ages...
