Stainless steel crowns (SSCs), also known as silver crowns were first described in the 1950s by Engel. [3] They exist in different forms, either completely made of metal (preformed metal crowns) or with a layer of composite material covering the metal to improve esthetics (open-faced SSCs or pre-veneered SSCs).
A large amount of tooth structure is removed irreversibly during crown preparation. All restorations have impaired structural and functional integrity when compared to healthy, natural tooth structures. As a result, if a dental practitioner does not recommend it, crowning a tooth is probably not a good idea.
Conventional stainless steel crown; conventional stainless steel crowns require tooth preparation, usually interproximal and occlusal reductions. Under most circumstances this procedure will require local anesthetic. This procedure is invasive and there is loss of biological dental tissues, which is not required for Hall Technique stainless ...
Fluoride varnish is widely used in the United Kingdom, following guidelines from multiple sources backing its efficacy. Public Health England, a UK government organisation sponsored by the Department of Health, released guidance in 2014 recommending fluoride varnish application at least twice yearly for children and young adults.

Water fluoridation is the most cost-effective way to induce fluoride, with an estimated cost between US$0.50 and $3.00 per person per year, depending on the size of the community involved. [33] A dollar spent on fluoridating water is estimated to save $7–42 on dental treatment. [33]
Topical fluorides are fluoride-containing drugs indicated in prevention and treatment of dental caries, particularly in children's primary dentitions. [1] The dental-protecting property of topical fluoride can be attributed to multiple mechanisms of action, including the promotion of remineralization of decalcified enamel, the inhibition of the cariogenic microbial metabolism in dental plaque ...
After the prefabricated post is properly cemented into the post space, a core material, such as dental composite, can be packed around the cemented post. After the material has been cured or has had a chance to set and properly formed into a crown preparation, an impression can be taken for the fabrication of a prosthetic crown. [9]
