Recent developments in bone tissue engineering have led to an increased interest in one-dimensional (1D) hydroxyapatite (HA) nano- and micro-structures such as wires, ribbons and tubes. They have been proposed for use as cell substrates, reinforcing phases in composites and carriers for biologically active substances. Here we demonstrate the synthesis of 1D HA structures using an optimized, ure...
The effect of addition of NaHF2 on the cement setting and the set mass has been studied as an initial step to determine how fluoride influences the characteristics of a calcium phosphate cement, consisting of tetracalcium phosphate [TTCP:Ca4 (PO4)2O] and dicalcium phosphate dihydrate [DCPD:CaHPO4.2H2O].NaHF2 [0-10% wt% of powder phase] has been dissolved in double distilled water and used as th...
Identification of dicalcium phosphate dihydrate deposited during osteoblast mineralization in vitro.
The hydroxyapatite (HAP) with variable chemical substitutions has been considered as the major component in the mineralized part of bones. Various metastable crystalline phases have been suggested as transitory precursors of HAP in bone, but there are no consensuses as to the nature of these phases and their temporal evolution. In the present study, we cultured rat calvarial osteoblasts with as...
Background: Calcium phosphates (CPs) form hydroxyapatite (HA) in physiological solutions. These are commonly used to treat dentine hypersensitivity (DH) as they mimic the mineral composition of natural tooth. Aim: The present study aims characterise apatite formation ability a commercially available calcium phosphate TeethmateTM (TM) physiological-like media. Materials and Methods: In this stud...
