Dietary Fluoride Intake by Children: When to Use a Fluoride Toothpaste?

Fluoride is recommended for its cariostatic effect, but excessive fluoride intake may have health risks. Increased prevalence of dental fluorosis in areas with low fluoride content in drinking water has been attributed to the inappropriate excessive intake of fluoride supplements (tablets and drops) and toothpaste ingestion. The aim of the present study was to estimate the fluoride intake and the risk of fluorosis in children (6 months-6 years) in the Castelli Romani area (province of Rome, Italy), which is volcanic, therefore with a higher concentration of fluorine. Measurements of the fluoride content in drinking water, mineral waters, vegetables and commercial toothpaste for children were performed. The fluoride concentrations of all samples were determined using a Fluoride Ion Selective Electrode (GLP 22, Crison, Esp). Data were analyzed by descriptive statistics. Differences between samples were determined by Student's t-test. The fluoride content in tap water samples collected from public sources averaged from 0.35 to 1.11 ppm. The Pavona area showed the highest content of fluoride with respect to the others (p ≤ 0.05). The fluoride content in mineral water samples averaged from 0.07 to 1.50 ppm. The fluoride content of some vegetables showed increased mean values when compared to control vegetables (p ≤ 0.05). Within the limitations of the present study, considerations should be made when prescribing fluoride toothpaste for infants (6 months-4 years) in the areas with high fluoride content, because involuntary ingestion is consistent.

Hemostasis control in dental extractions in patients receiving oral anticoagulant therapy: an approach with calcium sulfate.

The aim of this study was to evaluate the use of calcium sulfate (CaS) as a hemostatic agent after tooth extraction in patients with anticoagulant drug therapy. A total of 30 patients undergoing anticoagulant therapy (22 women and 8 men) with a mean age of 54.6 years (SD = 9.2 years), needing dental extractions, were selected for this study. They were divided into 2 groups, control (group 1) and test (group 2), in a randomized way. In group 1 patients, the postextraction socket was managed with obliterative suture only. Group 2 patients were treated with CaS placed into the postextraction sockets. All the patients did not interrupt the anticoagulant therapy during the dental treatment. The healing pattern was found to be approximately similar in all treatment groups, showing significant improvement at each consecutive visit. However, a statistically significant difference in the adequate hemostasis was evident between groups 1 and 2 (P = 0.0056). The use of CaS helped to control the bleeding from inside the socket, producing instantly a very good hemostasis. Further studies are necessary to confirm the simplicity, possibilities, and limits of the proposed procedure.
