New Mexico Dental Assisting License Practice Exam

The correct choice identifies a type of glass ionomer material specifically categorized as Type I. This material is a hybrid of silicate and polycarboxylate, which contributes to its unique properties. Glass ionomer materials are known for their ability to release fluoride, making them effective in preventing dental caries, a crucial advantage in restorative dentistry.

Type I glass ionomer is primarily used for cementation purposes, such as in the bonding of orthodontic brackets, and is distinguished by its strength and adhesion to both enamel and dentin. The incorporation of silicate allows for good aesthetics in comparison to traditional materials, while polycarboxylate enhances its bonding capabilities.

Understanding the different types of glass ionomer materials is essential for properly selecting dental materials based on their intended use. Other types, such as Type II or Type III glass ionomers, serve different applications like restorative procedures or temporary fillings, which do not align with the question's focus on a hybrid materials context for cementation.
