To minimize these types of error and maximize clinical success, dental material manufacturers have evolved a range of material presentations to minimize the risk of mishandling. Perhaps surprisingly, when considering their diversity, the materials that are used across the various branches of dentistry have much in common. Composite resin restorations of all kinds lack the ability to bond naturally to the tooth. Characteristics of dental materials that can affect the adhesion process are wetting, viscosity, surface characteristics, and film thickness. Wear PPE's Actually, amalgam consists of several different metals, with silver being the predominant metal. Dental materials may set chemically, or the setting may be initiated by light energy, or a combination of both. Stress: measure of the intensity or internal distribution of the total internal forces acting within a deformable body. Lastly, When dental materials are placed in the mouth, they enter a very hostile environment. Mayo Clinic, Rochester, Minn. Dec. 16, 2018. Saliva contains salt, which makes it a good conductor of electricity. https://www.aaoms.org/practice-resources/aaoms-advocacy-and-position-statements/clinical-resources.

Thermal Changes True or False Dental materials contract or expand at the same rates. Curing is a setting process of a dental material that is initiated by a chemical reaction or by light in a blue wave spectrum. 43 workbook.docx - Amber Rivera 43 Restorative and Esthetic Dental a. Cost is the significant factor in treatment decision. - must confirm and function, List the properties of dental materials, and explain how these properties affect their application, - flow - must be pliable enough be adapted in preparation; for placement. They are subjected to the hostile environment which is the human mouth, where they are asked to endure similar stresses and strains during function. A scanning electron micrograph and pictorial representation of a granular glass ionomer powder. Cured Preserved or finished by a chemical or physical process. Microleakage (mye-kroe-LEE-kuj) Microscopic space located at the interface of the tooth structure and the sealant or restoration.
