Cast base-metal alloys are rarely used to make full metal crowns. They are more commonly used as part of metal-ceramic crowns as bonding alloys. When compared to high-noble and noble alloys, they are stronger and harder; they can be used in thinner sections (0.3mm as opposed to 0.5mm) however they are harder to adjust and are more likely to ...
Inorganic filler such as silica, quartz or various glasses, are added to reduce polymerization shrinkage by occupying volume and to confirm radio-opacity of products due to translucency in property, [clarification needed] which can be helpful in diagnosis of dental caries around dental restorations. The filler particles give the composites wear ...
There are multiple randomised controlled trials that have shown the Hall Technique to be superior to other methods for managing decay in baby teeth, [1] but there is a lack of evidence to conclude that the Hall Technique is superior to placing preformed metal crowns in a conventional manner. [2]
Amalgam is a mixture of two or more metals (alloy) with mercury which has been purified first by distillation to remove impurities. Major components of the alloy are silver, tin, and copper. The composition of the alloy powder is controlled by ISO standard for dental amalgam alloy (ISO 1559) to control the properties of amalgam. [11]
Dental restorative materials are used to replace tooth structure loss, usually due to dental caries (cavities), but also tooth wear and dental trauma. On other occasions, such materials may be used for cosmetic purposes to alter the appearance of an individual's teeth.
Since dental floss is able to remove some inter-proximal plaque, frequent regular dental flossing will reduce inter-proximal caries and periodontal disease risks. [1] [3] Results of a high level of evidence meta-analysis recently found that floss may not be the most effective method for interdental cleaning, contrary to common belief at the ...

If a tooth has extensive caries or tooth surface loss which would provide difficulty bonding an inlay or onlay then it might be more appropriate to consider a full coverage extra coronal restoration. This can protect remaining tooth structure. Direct restorations, for example composite may be beneficial when restorations are small.
