Glass ionomer can be effectively used for which type of teeth?

Glass ionomer cement is particularly well-suited for use in primary teeth and partially erupted molars due to its favorable properties. This material releases fluoride, which provides additional protection against caries, making it beneficial for primary teeth that are more susceptible to decay. It also has the unique ability to bond chemically with both the tooth structure and dentin, which is advantageous in young patients where the primary teeth may have not fully developed or where there's minimal space and depth for traditional restorative materials.

Additionally, since glass ionomer can accommodate some movement of the teeth as they erupt, it is ideal for partially erupted molars. This flexibility is important in pediatric dentistry, where growth and development are ongoing and can affect the dental structure. In contrast, materials intended for permanent molars might not be as effective or necessary in treating primary teeth, which often have a different set of requirements. The other options focus on specific tooth types that do not consider the broader versatility and benefits of glass ionomer in pediatric dentistry.
