Cylindrical Cavities

The polymerization shrinkage of light-cured composite resin, a dental restoration material, was studied using three different experimental methods. Digital image correlation method was used to examine the shrinkage deformation on the free surface of artificial cylindrical cavities. X-ray CT images and the digital image correlation were employed to measure the shrinkage deformation in the cavities. The shrinkage force was measured at the floor of the cavity using a load-cell, and evaluated as functions of time and the depth of the cavity.

New Generation

In 1955, Buonocore introduced the etching of enamel with phosphoric acid. Bonding to enamel was created by mechanical interlocking of resin tags with enamel prisms. Enamel is an inert tissue whose main component is hydroxyapatite (98% by weight). Conversely, dentin is a wet living tissue crossed by tubules containing cellular extensions of the dental pulp. Dentin consists of 18% of organic material, primarily collagen. Several generations of dentin bonding systems (DBS) have been studied in the last 20 years. The dentin bond strengths associated with these DBS have been constantly lower than the enamel bond strengths. Recently, a new generation of DBS has been described. They are applied in three steps: an acid agent on enamel and dentin (total etch technique), two mixed primers and a bonding agent based on a methacrylate resin. They are supposed to bond composite resin to wet dentin through dentin organic component, forming a peculiar blended structure that is part tooth and part resin: the hybrid layer.
