Tooth whitening or tooth bleaching is the process of lightening the colour of human teeth. [1] Whitening is often desirable when teeth become yellowed over time for a number of reasons, and can be achieved by changing the intrinsic or extrinsic colour of the tooth enamel . [ 2 ]
Remineralization is a natural process and does not have to involve fluoride. Tooth remineralization is the natural repair process for non-cavitated tooth lesions, [1] [2] in which calcium, phosphate and sometimes fluoride ions are deposited into crystal voids in demineralised enamel. Remineralization can contribute towards restoring strength ...
In dental enamel, fluorosis causes subsurface porosity or hypomineralizations, which extend toward the dentinal-enamel junction as the condition progresses and the affected teeth become more susceptible to staining. Due to diffusion of exogenous ions (e.g., iron and copper), stains develop into the increasingly and abnormally porous enamel. [7]
It does not resorb, and is biocompatible, forming a seal against the tooth material that minimizes leakage. [1] Originally, MTA was dark gray in color, but white versions have been on the market since 2002. Bismuth oxide, which was added as a radioopacifier (to make the filling stand out on X-rays), [citation needed] can discolour the teeth. [3]
Air abrasion is a dental technique that uses compressed air to propel a thin stream of abrasive particles—often aluminum oxide or silica—through a specialized hand-piece to remove tooth tissue and decay before being suctioned away, similar to sand blasting.
Fluoride varnish is a highly concentrated form of fluoride that is applied to the tooth's surface by a dentist, dental hygienist or other dental professional, as a type of topical fluoride therapy. [1] It is not a permanent varnish but due to its adherent nature it is able to stay in contact with the tooth surface for several hours.
According to a 2012 review article by Demarco et al. covering 34 relevant clinical studies, "90% of the studies indicated that annual failure rates between 1% and 3% can be achieved with Class I and II posterior [rear tooth] composite restorations depending on the definition of failure, and on several factors such as tooth type and location ...
