Atraumatic restorative treatment. Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments (dental drills) to prepare the tooth and can be performed in settings ...
The primary aim of conservation is to slow the rate of deterioration, caused by various factors, to the point where the loss of significance, such as historic information and/or aesthetic value can be kept to a minimum (Pye 2001, Ch. 5). However, in the case of stained glass, these efforts are complicated by the nature of the medium itself.
The most common method of adding the black linear painting necessary to define stained glass images is the use of what is variously called "glass paint", "vitreous paint", or "grisaille paint". This was applied as a mixture of powdered glass, iron or rust filings to give a black colour, clay, and oil, vinegar or water for a brushable texture ...
Glass coloring and color marking. Beer bottles of different colors. Glass coloring and color marking may be obtained in several ways. by the addition of coloring ions, [1][2] by precipitation of nanometer-sized colloids (so-called striking glasses[1] such as "gold ruby" [3] or red "selenium ruby"), [2] Ancient Roman enamelled glass, 1st century ...
After the needles are placed into the mass, cells are withdrawn by aspiration with a syringe and spread on a glass slide. The patient's vital signs are taken again, and the patient is removed to an observation area for three to five hours. For biopsies in the breast, ultrasound-guided fine-needle biopsy is the most common. The biopsy is advised.
The binder is a combination of silica sol and water glass. The organic fraction is limited to 5 mass percent similar to dispersion silicate paint allowing for chemical setting and retaining of the silicate specific advantages. The sol silicate paint allows use on non-mineral plaster. [4] For these the bonding occurs chemically and physically.
Pulp capping is a technique used in dental restorations to protect the dental pulp, after it has been exposed, or nearly exposed during a cavity preparation, from a traumatic injury, or by a deep cavity that reaches the center of the tooth, causing the pulp to die. [1] Exposure of the pulp causes pulpitis (an inflammation which can become ...
Dental composites. Glass ionomer cement - composite resin spectrum of restorative materials used in dentistry. Towards the GIC end of the spectrum, there is increasing fluoride release and increasing acid-base content; towards the composite resin end of the spectrum, there is increasing light cure percentage and increased flexural strength.
