European Organization for Caries Research Workshop: Methodology for Determination of Potentially Available Fluoride in Toothpastes.

Toothpastes are the most universally accepted form of fluoride delivery for caries prevention. To provide anti-caries benefits, they must be able to release fluoride during the time of tooth brushing or post brushing into the oral cavity. However, there is no standard accepted procedure to measure how much fluoride in a toothpaste may be (bio) available for release.

Consensus document on transthoracic echocardiography in Portugal.

Echocardiography is the most widely used imaging technique in modern cardiological clinical practice, since it is readily available, portable and safe, and provides a comprehensive morphological and functional assessment at low cost compared to other imaging modalities. Recent technological advances have introduced new echocardiographic techniques and widened the clinical applications of echocardiography. However, these developments have also led to an increase in information, rendering interpretation of the data provided by the exam more complex; this may result in assessment errors by less experienced operators.
