Dental Composites - A cosmetic tooth filling

Explore the basic components of composite resin, including resin matrix, coupling agents, fillers, activator, initiator system, inhibitors, and coloring agent, and preview detailed discussion in upcoming sections.

Explore how fillers like silica glass occupy a major portion of dental composites. Boost modulus of elasticity, compression and tensile strength, abrasion resistance, and reduce water sorption and polymerization shrinkage.

Examine activator initiator systems in dental composites, comparing chemical activation to light activation. Understand self cure chemistry with benzoyl peroxide and tertiary amine forming free radicals to start polymerization.

Explore the curing of composites by chemical activation (cold curing), light activation, and photo curing with visible blue light, detailing polymerization, 40s curing time, and related advantages and disadvantages.

Understand solubility as the dissolution of a restorative material in oral fluids over time; composites and amalgam show no solubility, while gases have greater solubility.

Identify contraindications of composite restoration, including deep or wide class II lesions near the pulp and difficult isolation. Emphasize the technique sensitivity and required clinician training to prevent failure.

Explore the general classifications of tooth preparation for composite restorations, including conventional, beveled conventional, modified tooth preparations, porcelain preparation, and facial or slot preparations, with detailed coverage in this section.
