The form, location, and distribution of fluorhydroxyapatite deposited in dental plaque by a urease-mediated mineral enrichment process have been studied by transmission electron microscopy. Artificial plaque was formed in terylene gauze in the mouth of one subject and immersed for five min four times per day in a mineral-enriching solution. Contralateral control plaque remained untreated. The e...

The resorption of brushite-based bone cements has been shown to be highly unpredictable, with strong dependence on a number of conditions. One of the major factors is phase transformation, with change to more stable phases such as hydroxyapatite affecting the rate of resorption. Despite its importance, the analysis of phase transformation has been largely undertaken using methods that only dete...

As the population ages worldwide, importance of maintaining metabolism skeletal system becomes increasingly important. The skeleton is core locomotor and oral structure. Moreover, infection control an essential part orthopedic surgery. This paper investigates new bone substitutes fabricated by ionic substitution method leading to octacalcium phosphate (OCP) with excellent contact antibacterial ...

Hydroxyapatite (HAp) is a major component of bones and teeth. HAp widely used to repair, fill, extend, reconstruct damaged bone tissue. for dental implants, so it necessary synthesize HAp. synthesis can utilize green mussel shell waste as calcium precursor. This research synthesized from using the sol-gel method. The controlled parameter was pH, variable being compared heating temperature at 90...
