What type of cement is classified as Type I cement?

Type I cement refers to luting agents, which are materials primarily used to bond or adhere indirect restorations, such as crowns and bridges, to the tooth structure. These cements are designed to provide a durable bond while allowing for some moisture control and sensitivity amendment between the tooth and restoration.

Luting agents, as Type I cements, have specific properties that make them suitable for this purpose, including the ability to flow and create a thin layer of bond that is effective in sealing the margins of the restoration. This is crucial for preventing micro-leakage and secondary caries, as well as ensuring the longevity of the restoration.

While adhesive cements (another form) also function to bond, they might not be categorized strictly within the Type I classification. Temporary cements are specifically designed for short-term use, thus not qualifying as a Type I cement, and resin-modified glass ionomer cements, while effective for certain applications, are considered part of different classifications based on their composition and intended use.

Thus, understanding the role of luting agents within the hierarchy of dental cements is essential for proper application in restorative dentistry, and this classification helps guide dental assistants and professionals in selecting the appropriate materials for different clinical scenarios.
