Hammassementteinä refers to dental cements, which are adhesive materials used in dentistry for various purposes. These materials play a crucial role in restorative and cosmetic procedures, bonding dental prosthetics to teeth and providing temporary or permanent filling solutions.

The primary functions of dental cements include luting crowns, bridges, inlays, and onlays to prepared tooth structures. They also serve as bases or liners beneath restorations to protect the pulp from thermal shock and chemical irritation. Additionally, some dental cements are utilized as temporary fillings or for sealing orthodontic bands.

Dental cements are typically composed of a powder and a liquid component that are mixed to form a paste. The powder often contains zinc oxide, silica, or other mineral compounds, while the liquid can be phosphoric acid, water, or organic monomers. The setting reaction varies depending on the cement type, involving chemical or physical processes.

Various types of dental cements exist, each with specific properties and applications. Glass ionomer cements are known for their fluoride release, which can help prevent secondary decay. Resin-based cements offer superior strength and esthetics. Zinc phosphate cements are strong and biocompatible but lack adhesion to tooth structure. Polycarboxylate cements provide good adhesion and are gentle to the pulp. The choice of cement depends on the specific clinical situation, the type of restoration, and the desired properties such as strength, adhesion, esthetics, and biocompatibility.
