Increased extraosseous uptake of sodium fluoride can be visualized because of many different etiologies. A 62-year-old man with a history of osteoporosis had an F-sodium fluoride PET/CT scan for accessing chest pain caused by an accident. The images showed multiple fractures. Unexpectedly, diffuse activity was noted in the gastric wall, which was suggestive of possible hypercalcemia. The serum calcium level confirmed the patient had hypercalcemia.

Cyclopropane is a significant alicyclic motif, widely utilized in medicinal chemistry, while fluorination serves as a powerful tool to modulate properties that enhance the performance of pharmaceuticals and materials. This quantum-chemical study explores the energetic implications of fluorinating cyclopropane, providing insights into molecular characteristics arising from the polar C-F bond. Isodesmic reactions revealed that the conversion of cyclopropane and methyl fluoride into mono-, di-, tri-, tetra-, penta-, and hexafluorinated cyclopropanes is exothermic, except for the all--1,2,3-trifluorocyclopropane ().

This 30-mo double-blind randomized clinical superiority trial aimed to assess the effectiveness of semiannual application of 38% silver diamine fluoride (SDF) solution in preventing early childhood caries in primary upper anterior teeth. The active comparator was 5% sodium fluoride varnish (FV). The primary outcome was the mean number of new carious tooth surfaces per child at the 30-mo follow-up.

Excessive fluoride (F) exposure, particularly during early development, poses a significant risk to skeletal integrity by disrupting bone homeostasis through oxidative stress and altered mineralization. While F induced oxidative stress is well documented, studies investigating the role of natural antioxidants in mitigating F induced osteochondral toxicity remains limited. Hence, the present study investigated the osteomodulatory effect of fisetin (Fis) against F toxicity in zebrafish larvae.

Cemented paste backfill has made outstanding contributions to the large-scale consumption of phosphogypsum (PG), but poor water resistance significantly weakens the mechanical strength, promotes the leaching of total soluble phosphate (TP) and fluoride ions (F), and reduces its attractiveness in mine engineering. This research synthesized a curing agent (CA) using sodium methylsilicate, sodium silicate, and polyaluminum chloride (PAC). PG produced from Deyang Haohua Qingping Phosphate Mine Co.
