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 ...
Microscope slide. A set of standard 75 by 25 mm microscope slides. The white area can be written on to label the slide. A microscope slide is a thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope. Typically the object is mounted (secured) on the slide, and ...
Tooth whitening or tooth bleaching is the process of lightening the color of human teeth. [ 1 ] Whitening is often desirable when teeth become yellowed over time for a number of reasons, and can be achieved by changing the intrinsic or extrinsic color of the tooth enamel. [ 2 ] The chemical degradation of the chromogens within or on the tooth ...
Dental restoration, dental fillings, or simply fillings are treatments used to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as to the replacement of such structure supported by dental implants. [1] They are of two broad types— direct and indirect —and are further ...
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.
After the needles are placed into the mass, cells are withdrawn by aspiration with a syringe and spread on a glass slide.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.
Staining. A stained histological specimen, sandwiched between a glass microscope slide. Staining is a technique used to enhance contrast in samples, generally at the microscopic level. Stains and dyes are frequently used in histology (microscopic study of biological tissues), in cytology (microscopic study of cells), and in the medical fields ...
Histopathology (compound of three Greek words: ἱστός histos 'tissue', πάθος pathos 'suffering', and -λογία -logia 'study of') is the microscopic examination of tissue in order to study the manifestations of disease. Specifically, in clinical medicine, histopathology refers to the examination of a biopsy or surgical specimen by a ...
