Colour Constancy of Dental Porcelain after Exposure to Universally Consumed Beverages: A Methodical Review of Literature
نویسنده
چکیده
For dental porcelain, precise shade matching of tooth coloured restoration with the adjacent dentition is deemed necessary. However the colour instability in porcelain restoration is a common problem now a day’s particularly when they exposed to routinely consumable beverages which sever its nature of being tooth coloured. Therefore in this concern the authors has tried to emphasize the historical outlooks, researches on colour stability and difficulties and current trends for colour stability in tooth coloured restorative materials predominantly dental porcelains. A meticulous literature search was executed using MEDLINE/PubMed and other scholarly research bibliographic databases using Medical Subject Headings (MeSH) from 1950 to 2017. Study results showed that there is no ceramic existing which could be classified as total stain free.

Reactive airway dysfunction syndrome (RADS) is a type of non-immunologically mediated asthma-like disease. It usually occurs after a massive exposure to an irritating substance in the atmosphere in the form of smoke, fumes, gases, and vapor. Unlike bronchial asthma, there is no latency to the symptoms seen in RADS. A number of agents are known to cause RADS, but tile dust, as an etiological age...
