Hydroxyapatite (HA) is the main inorganic component of bone and teeth having high bioactivity, biocompatibility osteointegration capability. Recently, wollastonite (WT) has been offered to reinforce HA further increase also mechanical strength. The focus this study was produce characterize HA/WT composite granules with spray drying. Commercial WT particles were introduced into lab made nanopart...

Aim: The purpose of the present study was to evaluate choice grafting options post apicectomy procedure by various endodontists. Methodology: In descriptive survey, 8 questions were asked from 50 Endodontists, regarding treatment in cases periapical pathologies as well graft material preference after apicoectomy performed. They for usability, economics, long term healing region related with pla...

Objectives: 1.To clinically evaluate the healing process following periapical surgery with Chitra granules 2.To radiographically evaluate healing, following periapical surgery with Chitra granules. 3.To compare the bone healing in the study group, clinically and radiographically following the modalities of treatment, with that of the control group (without graft). Materials: 1.Chitra hydroxyapa...

PURPOSE To review the radiology and histology of synthetic bone grafts resected from patients with recurrent giant cell tumour (GCT) of bone. METHODS 22 patients underwent curettage and grafting for GCT of bone using autogenous cancellous bone mixed with apatite-wollastonite-containing glass ceramic (AWGC), hydroxyapatite (HA), or a mixture of HA and tricalcium phosphate (TCP). Patients were ...

Aerobic granular sludge is a promising process for nutrient removal in wastewater treatment. In this work, for the first time, biologically induced precipitation of phosphorus as hydroxyl-apatite (Ca(5)(PO(4))(3)(OH)) in the core of granules is demonstrated by direct spectral and optical analysis: Raman spectroscopy, Energy dispersive X-ray (EDX) coupled with Scanning Electron Microscopy (SEM),...
