Background
As silver diamine fluoride (SDF) gains popularity for caries arrest, the authors aimed to investigate the content of fluoride and silver in 38% SDF produced for the US market and its short-term stability.Methods
Five samples of 38% SDF were evaluated when the bottle was first opened, and at 7 and 28 days. Fluoride concentrations were determined with a fluoride ion-selective electrode, and silver concentrations were determined with a simultaneous inductively coupled plasma mass spectrometer. pH was measured with a pH probe. Weight and volume of individual drops were measured.Results
At day 0, 40% of individual measured values were above the expected fluoride concentration, and at day 28, 93% were above the expected fluoride concentration (P = .005). At day 0, 19% of individual measured values were below the lowest expected silver concentration, and at day 28, 93% were below (P < .001). Acidity (pH 10) was consistent over the 3 periods. Mean (standard deviation) weight of a drop was 40 (4.0) milligrams, and mean (standard deviation) volume was 32.55 (1.89) microliters, 30% more than the reported value of 25 μL.Conclusion
Over 28 days, the product pH is stable, whereas the fluoride content tends to increase and the silver content tends to decrease. Drops were larger than expected when dispensed from the bottle.Practical Implications
Drops are larger than expected, so each delivers higher than expected quantities of silver and fluoride. Clinicians should exercise caution when using this product on young children, replace the cap immediately, and use as soon as dispensed. 相似文献2.

To identify correlates of sexual behaviors among Thai young adults between 18 and 24 years, the authors used a cross-sectional survey of 405 young adults from eight randomly selected Thai urban and rural vocational schools. The young adults completed self-report questionnaires. Logistic regressions were used to determine the correlates between a Thai young adult's ever having had sexual intercourse and the correlates of the number of sexual partners and consistent condom use among those who were sexually active. The independent variables were age, gender, socioeconomic status, geographic residence, parental residence, parental-young adult communication, HIV knowledge, and negotiation for safer sex. The results showed that geographic residence and negotiation for safer sex were related to a young adult's ever having had sexual intercourse; gender, HIV knowledge, and negotiation for safer sex were related to the number of sexual partners; and geographic residence was related to condom use. HIV prevention programs should incorporate HIV knowledge and negotiation skills for both genders and for all geographical areas. 相似文献
