The aim of this study was to investigate the sol gel synthesis of HA/FA nanoparticles and the possible formation of TCP phase or unstoichiometric calcium deficient hydroxyapatite (CDHA) from the precursors with a Ca/P ratio of 1.62. In order to prepare the sol, the solutions of Triethyl phosphite, ammonium fluoride and calcium nitrate in ethanol were used respectively as P, F and Ca precursors....

BACKGROUND This study aimed to evaluate and compare the efficacy of three desensitizing dentifrices on dentinal hypersensitivity (DH) and salivary biochemical characteristics. MATERIALS AND METHODS A randomized, parallel arm, triple-blinded, clinical trial was conducted over a period of 12 weeks, with a total of three visits: baseline, 6 weeks, and 12 weeks. Calcium sodium phosphosilicate, po...

Histochemical methods have been devised Lo demonstrate certain metabolic activities of cells. By these techniques certain structures in a particular tissue are made to stand out in contrast to the other constituents. We have applied the methods for demonstrating alkaline and acid phosphatase activity to the study of the skin in leprosy. Pearse (5) has pointed out that these methods depend on in...

Abstract The reaction of Mn(NCS) 2 with 3‐cyanopyridine in water accidentally leads to the formation single crystals (H O) ( 1 ). If synthesis is performed without 3‐cyanopyridine, known tetrahydrate 4 formed. In crystal structure new hydrate, Mn 2+ cations are linked by pairs μ‐1,3‐bridging anionic ligands chains, which further connected via units into layers, that additionally stabilized intr...
