Apatite precipitation on a novel fast-setting calcium silicate cement containing fluoride
Aim: Calcium silicate cements are widely used in endodontics. Novel fast-setting calcium silicate cement with fluoride (Protooth) has been developed for potential applications in teeth crowns including cavity lining and cementation. Objective: To evaluate the surface apatite-forming ability of Protooth compositions as a function of fluoride content and immersion time in phosphate-buffered salin...
متن کاملFabrication of biporous low-crystalline apatite based on mannitol dissolution from apatite cement.
Biporous (macro- and microporous) calcium phosphate gains much attention as a bone substitute material because of its large surface area and that it improves cell penetration. In the present study, we evaluated the feasibility of biporous, low-crystalline apatite based on dissolution of mannitol from self-setting apatite cement (Biopex). Mannitol--known as a biocompatible, easily dissolved mono...
متن کاملPreparation of porous apatite granules from calcium phosphate cement.
A versatile method for preparing spherical, micro- and macroporous (micro: 2-10 and macro: 150-550 microm pores), carbonated apatitic calcium phosphate (Ap-CaP) granules (2-4 mm in size) was developed by using NaCl crystals as the porogen. The entire granule production was performed between 21 and 37 degrees C. A CaP cement powder, comprising alpha-Ca3(PO4)2 (61 wt.%), CaHPO4 (26%), CaCO3 (10%)...
متن کاملDevelopment of calcium phosphate cement for rapid crystallization to apatite.
The purpose of this study was to develop an alpha-tricalcium phosphate (alpha-TCP) cement which transforms to hydroxyapatite (HAP) in a relatively short period. We used calcium and phosphate solutions as the liquid phase for the alpha-TCP cement. The alpha-TCP powder was first mixed with CaCl2 solution, and then mixed with NaH2PO4 or Na2HPO3 solution for a total powder/liquid ratio of 1.8. The ...
متن کاملeffect of nano hydroxy apatite on artificial carious lesions created on extracted teeth
background. many types of toothpastes contain substances that can remineralize initial enamel caries. this study aimed to assess the effect of nano-hydroxyapatite (nha) on microhardness of artificially created carious lesions. methods. in this in vitro study, nha was prepared using sol-gel technique and added to the toothpaste with 7% concentration. a total of 80 extracted sound teeth were coll...
