3d bioprinting technologies for hard tissue and organ engineering... Over the last two decades, a wide variety of 3D printing technologies have been adapted to hard tissue and organ engineering...
A three phase study involving the experimental synthesis and characterization of nano-particulate sealers, their cytotoxic evaluation followed by analysis of their antimicrobial efficacy in an exvivo model under confocal laser scanning microscope... Followingincubation the teeth were sectioned transversely at the coronal, middle and apical regions (n=63)using a hard tissue microtome and the roots were stained with fluorescent DNA binding reagents(FluoresceineDiacetate andpropidium iodide)...
Clinical and radiographic evaluation of citric acid-based nano hydroxyapatite composite graft in the regeneration of intrabony defects - a randomized controlled trial... Plaque index, gingival index, gingival bleeding index, probing pocket depth (PPD), clinical attachment level (CAL), bone probing depth (BPD) and hard tissue parameters such as amount of defect fill, percentage of defect fill, and changes in alveolar crest were assessed over a period of 12 months...
The efficacy of novamin powered technology oravive and topexrenew, crest and prevident 5000 plus in preventing enamel demineralization and white spot lesion formation... Following the cycling protocol the teeth were sectioned using the hard tissue microtome producing three to five sections per tooth...
