Plaques of hard exudate measuring 0-5 to 10 disc diameters, which occurred in 5 eyes of 4 patients with diabetic maculopathy, showed complete organisation in 8 to 18 months with the formation of scars measuring 0-2 to 0 5 disc diameters. The visual acuity was related to the size and situation of the scar within the fovea, and, when the foveola was involved by plaque formation, visual reduction ...
The mechanism of the formation of a self-aligned hydroxyapatite (HAP) nanocrystallite structure was examined. It is found that the highly ordered HAP nanocrystallite assembly is attributed to the so-called self-(homo)epitaxial nucleation and growth. On the other hand, according to this mechanism, a high supersaturation will give rise to a random assembly of HAP crystallites. The effects of ions...
There are several studies about the cytotoxic effects of dental materials in contact with the pulp tissue, such as calcium hydroxide (CH), adhesive systems, resin composite and glass ionomer cements. The aim of this review article was to summarize and discuss the cytotoxicity and biocompatibility of materials used for protection of the dentin-pulp complex, some components of resin composites an...
