Evaluation Of Clinical Performance of Self-adhering Flowable Composite vs Conventional Flowable Composite in Cervical Carious Lesions

Dental Caries

This clinical trial will be conducted to compare the clinical performance of a new self-adhering flowable composite in restoring CLs compared to conventional flowable composite in geriatric patients over 12 months.

Recently, self-adhesive flowable composites (SAFCs) have been introduced as a new class of restorative material in adhesive dentistry. Today, there are only two available products in the market for clinical use: Vertise Flow and Fusio Liquid Dentin. Self-adhering flowable composite was introduced to address the time-consuming procedure used with traditional materials Their resin matrix contains acidic functional adhesive monomers mediating bonding with dental hard tissues and, therefore, separate etching and additional bonding are not required. SAFCs have been mainly advertised for the restoration of small Class I, Class III and V cavities, for cavity lining, and for use as a pit and fissure sealant. Self-adhering flowable composite combines the merits of both adhesive and restorative material technologies in one product, bringing novel horizons to restorative techniques, as it is a direct composite resin restorative material that has an adhesive resin together with a flowable composite resin. It is based on the bonding technology that uses glycerophosphate dimethacrylate(GPDM)to etch enamel and dentin, and hydroxyethyl methacrylate (HEMA) to enhance wetting and penetration by resin into dentin. This resin bonds chemically between the phosphate groups of a GPDM monomer and the hydroxyapatite of tooth structure and, also, micromechanically between the polymerized monomers of the self-adhering flowable composite resin and the collagen fibers and smear layer of dentin.
