Which luting agent is considered the most versatile?

The most versatile luting agent is glass ionomer cement. This material is known for its unique properties that allow it to effectively bond to both tooth structure and various restorative materials, including metal and ceramic. Glass ionomer cement releases fluoride, which can help protect the tooth from decay and support long-term health. It also has good biocompatibility and can be used in a range of clinical situations, from cementing crowns and bridges to providing a liner for cavity preparations.

Additionally, glass ionomer does not require bonding agents like some resin cements, making it easier and faster to use in certain situations, particularly in areas where moisture control can be a challenge. These factors contribute to its reputation as a versatile option for dental professionals, allowing it to be used in a variety of restorative and preventative applications.

In contrast, while resin cement is also versatile and offers strong adhesion for aesthetic cases, its use is typically more specific to situations requiring superior aesthetics or retention. Gypsum is primarily used for making casts and models, thus it does not function as a luting agent for dental restorations. Traditional cement, while effective for certain applications, lacks the properties that make glass ionomer superior in versatility and clinical applications.
