A modified sol-gel process for synthesizing nanocrystalline hydroxyapatite powders (nHA) for biomedical applications, using tetrahydrated calcium nitrate [Ca(NO(3))(2)∙4H(2)O] and phosphorous pentoxide [P(2)O(5)] as precursor, is presented and discussed. The powders were washed and heat-treated at different temperatures and then characterized by X-ray diffraction (XRD), scanning electron micros...
BACKGROUND Bone graft procedures have been used commonly in buco-maxillo-facial surgery. For this reason, many researchers have evaluated the bone substitutes. PURPOSE The present study evaluated soft and hard tissue reactions to two different hydroxyapatites HAs (synthetic HA and natural HA) and bioactive glass implanted into the sockets immediately after extraction. MATERIALS AND METHODS ...
Introduction: Mercury is one of the elements that are commonly found in nature. This element highly toxic, mainly affecting nervous system, kidneys and lungs. ions can accumulate bone cartilage build up behind calcium carbonates hydroxyapatites. High mercury concentrations spongy compared to compacted were found. Aim: The aim manuscript was assess content tibial femoral tissue taken from patien...
