Clinical Performance of Posterior Glass Ionomer Restorations in Adolescents (KETAC)

Clinical Performance of a Newly Developed Glass Ionomer Restorative Material for Posterior Restorations in an Adolescent Population

The purpose of this study is to determine whether two tooth-colored glass ionomer materials are effective for load-bearing dental fillings.

In this post-market longitudinal prospective randomized control clinical trial, posterior class II restorations will be evaluated for their clinical performance. The study will investigate the efficacy of two high-strength glass ionomer restorative materials for a period of up to 3 years.

Criteria:

• Inclusion Criteria:
• needs 2 Class II posterior restorations
• in good health
• sufficient oral hygiene
• vital tooth
• caries in the outer and/or middle third of dentin
• teeth must have at least one proximal contact to be restored
• isthmus is less than half the intercuspal distance
• has one or more enamel-supported antagonistic contact.
• both study restorations are not in contact with each other

Exclusion Criteria:

• pregnant or breast feeding
• erosion/eating disorders
• bruxism/traumatic malocclusion
• pulpitis
• cusp replacement
• radiographic bone loss/increased tooth mobility
