Amalgam is a metallic filling material composed from a mixture of mercury (from 43% to 54%) and a powdered alloy made mostly of silver, tin, zinc and copper, commonly called the amalgam alloy. [16] Amalgam does not adhere to tooth structure without the aid of cements or use of techniques which lock in the filling, using the same principles as a ...
The composition of dental amalgam is controlled by the ISO Standard for dental amalgam alloy (ISO 1559). [12] The major components of amalgam are silver, tin and copper. [12] Other metals and small amounts of minor elements such as zinc, mercury, palladium, platinum and indium are also present. [12]
The New England Children's Amalgam Trial (NECAT), a randomized controlled trial, yielded results "consistent with previous reports suggesting that the longevity of amalgam is higher than that of resin-based compomer in primary teeth, according to a 2007 review of the study, [22] with some similar claims in a 2003 paper, [30] and composites in ...
Systematic reviews and meta-analyses show that there are no differences between ART/HVGIC restorations in terms of longevity in primary teeth (for both single- and multiple-surface lesions) compared to the conventional methods using either amalgam [19] [20] [21] or resin composite. [22] [23]
The two case studies illustrate the method's conservative nature and present a viable option for patients with enamel infractions who would prefer not to undergo more invasive procedures. [16] In another article, it emphasizes how the detection of enamel cracks has greatly improved due to recent technological advancements like transillumination ...
Regenerative endodontic procedures [1] is defined as biologically based procedures designed to replace damaged structures such as dentin, root structures, and cells of the pulp-dentin complex. [2] This new treatment modality aims to promote normal function of the pulp. It has become an alternative to heal apical periodontitis.
Due to its tooth like colour, porcelain provides better aesthetic value for the patient. In more recent years, inlays and onlays have increasingly been made out of ceramic materials. In 1985, the first ceramic inlay created by a chair-side CAD-CAM device was used for a patient. [2] More recently, in 2000, the CEREC 3 was introduced.
During the early 1980s, advances in the area of visible-light curing led to the creation of a curing device using blue light. The next type of curing light developed was the quartz-halogen bulb ; [ 4 ] this device had longer wavelengths of the visible light spectrum and allowed for greater penetration of the curing light and light energy for ...
