cavity preparation

Upon mixing of the material components, there is no light cure needed to harden the material once placed in the cavity preparation.

Some dentists use technology like Waterlase, a laser-energy and water-spray process, for everything from root canals to cavity preparation.

This is clinically known as pulp recession; cavity preparation in young patients therefore carries a greater risk of exposing the pulp.

Composite resins experience a very small amount of shrinkage upon curing, causing the material to pull away from the walls of the cavity preparation.

In case of mechanical exposure that occurs during cavity preparation and not a pathological exposure due to caries .

Examples include all classes of cavity preparations for composite or amalgam, as well as those for gold and porcelain inlays.

A rapid accumulation of pulpal DCs has been observed beneath cavity preparations, and an increased number of DCs accumulated under caries.

Because of their high fluoride release and minimal cavity preparation requirement, glass ionomer cements are now widely the materisal of choice for the restoration of carious primary teeth.

Minimal cavity preparation required hence easy to use on children in and suitable for use even in absence of skilled dental manpower and facilities (such as in ART)

Early studies of dentinal walls after cavity preparation performed by Brännström and Johnson (1974) showed the presence of a thin layer of debris that was 2 to 5 micrometres thick.

Dentists use Erbium, chromium: yttrium-scandium-gallium garnet (Er,Cr:YSGG) lasers for cavity preparation and in endodontics.

The cavity preparation is first photographed and stored as a three dimensional digital model and proprietary software is then used to approximate the restoration shape using biogeneric comparisons to surrounding teeth.

The cavity preparation of a glass ionomer filling is the same as a composite resin; it is considered a fairly conservative procedure as the bare minimum of tooth structure should be removed.
