The Use of Heating to Change the Crystallinity and Structure of Carbonated Calcium Hydroxyapatite

Previous synthesis routes created apatite in low crystallinity and high crystallinity states, but a wider range will extend the design capabilities of apatities for hard tissue replacements.

Influence of nanohydroxyapatite mouthwash on the growth of Candida albicans biofilm on milled denture surfaces: An in vitro study

Journal of Prosthodontics, EarlyView.
Abstract Purpose There is a need for effective solutions for the persistent prevalence of denture stomatitis (DS) in denture‐wearing populations. This study assessed the impact of nanohydroxyapatite (nanoHAP) nanoparticles on Candida albicans biofilm formation on milled polymethylmethacrylate (PMMA) denture bases.

Oxygen isotope thermometry and composition of aqueous fluids within the parent body of asteroid (101955) Bennu

Meteoritics &Planetary Science, EarlyView.
Abstract We report on the petrography and oxygen isotopic compositions from in situ analyses of carbonates (Ca‐carbonate, dolomite, and Fe‐rich magnesite), magnetite, and apatite in particles from asteroid Bennu. Using oxygen isotope thermometry of Ca‐carbonate, dolomite, and magnetite, we estimated crystallization temperatures and the oxygen isotopic ...

Algorithm for Surgical Management in Patients in Treatment With Medication Associated With Osteonecrosis of the Jaws

Oral Surgery, EarlyView.
ABSTRACT Background Osteonecrosis of the jaws is associated with various drugs, including antiresorptives such as bisphosphonates and denosumab, as well as antiangiogenics. These drugs are used for the treatment of multiple diseases, notably osteoporosis, bone metastases, Paget's disease, osteogenesis imperfecta, malignant hypocalcaemia, among others ...

Structural characterization of synthetic and biological carbonated hydroxyapatite [PDF]

, 2010
It is well known that inorganic part of bones and teeth are impure form of hydroxyapatite, (HAp) Ca10(PO4)6(OH) 2. During the past few decades, great efforts have been invested to develop synthetic equivalent of natural apatite.

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.
