The intention of minimal intervention dentistry is to treat the patient for the disease of caries in the simplest manner possible commensurate with the problems diagnosed in that patient's oral environment. The term does not define or limit the extent of the treatment in any way. It simply suggests that the least complex treatment is generally the most desirable and prevention is better than cure. The use of the word intervention covers all types and complexities of treatment without specifying the method. Specifically it allows for treatment both with and without surgical intervention and recognises that nonsurgical treatment is just as important as preparation of a cavity.

It is now clear that surface cavitation of either enamel or dentine is the result of an imbalance in the demineralisation/remineralisation cycle that is constantly occurring on the tooth surface. The entire exposed tooth surface is covered with a layer of biofilm, which develops from the saliva, and acts as a filter as well as a protective coating. It supports the bacterial plaque within which carbohydrates in food and drink are broken down into acid and the pH level within the biofilm can be lowered to the extent that calcium and phosphate ions can be removed from the enamel or dentine. The majority of these ions is retained within the biofilm and can return in to the tooth surface as chemical activity reduces and the saliva neutralizes the pH. This chemical activity can be regarded as a continuum constantly fluctuating as a result of changes in the oral pH. However, there are a number of factors that can destabilize the situation and lead to an excess of demineralisation, with escape of some ions, and thus overall loss of mineral ions and ultimately surface cavitation.

Cavitation is the result of the disease; therefore restoration of a lesion alone will not arrest the disease. However, restoration of cavitation is a necessary part of elimination of the disease because it will not be possible to stabilize the oral flora in the presence of untreated caries. Therefore restoration should be undertaken in conjunction with measures to cure the disease. Simple placement of restorations is of no avail because the disease will continue and further lesions will develop.

Creating the best restorative material to substitute amalgam has been one of the most important challenges for the dental materials industry since the last decade, especially when the banning of mercury-based products became more widespread. The system of EQUIA is to combines a high-viscosity GIC (EQUIA Fil) with a highly filled light curing resin coating (EQUIA Coat). This technology integrates the main advantages of the high-viscosity GIC (self-adhesion, bulk application, improved mechanical properties) with a protective barrier in the early maturation phase and an improved surface hardness. When EQUIA Fil is coated with EQUIA Coat (EQUIA System) a marked increase in fracture toughness, flexural strength and flexural fatigue resistance are observed.
