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 ]
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 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 ...
Visual of tooth decay. Pulpotomy is a minimally invasive procedure performed in children on a primary tooth with extensive caries but without evidence of root pathology. [1] The minimally invasive, endodontic techniques of vital pulp therapy (VPT) are based on improved understanding of the capacity of pulp tissues to heal and regenerate plus the availability of advanced endodontic materials.
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.
The Julia olefination (also known as the Julia–Lythgoe olefination) is the chemical reaction used in organic chemistry of phenyl sulfones (1) with aldehydes (or ketones) to give alkenes (olefins)(3) after alcohol functionalization and reductive elimination using sodium amalgam or SmI 2. The reaction is named after the French chemist Marc Julia.
[8] [11] This procedure involved creating Class 1 cavity preps of teeth that were considered at risk of developing occlusal caries, which included all pits and fissures. [8] [11] The widening of the pits and fissures were then filled with amalgam. [8] [11] C.F Bödecker, a dentist and researcher, also made attempts to prevent occlusal caries.
