Brief summary

This study is conducted to evaluate the clinical performance of Zirconomer Improved GI restoration compared to Conventional viscous GI restoration in geriatric patients with Posterior carious lesions in class I or II cavities

Detailed description

This study will be conducted to determine the clinical performance of the Zirconia reinforced glass ionomer restorations ( Zirconomer improved) under stress bearing posterior area (class I or claa II cavities) in geriatric population in comparison to Conventional viscous glass ionomer restorations (Ketac molar quick Aplicap) using the modified United States Public Health Service (USPHS) criteria P: Geriatric Patients with posterior Caries lesions I: Zirconia reinforced GI (Zirconomer Improved) C: Conventional viscous GI, (Ketac Molar quick Aplicap) O: The Clinical performance of the Glass Ionomer restorations Using USPHS Criteria

Interventions

DRUGZirconomer Improved

glass ionomer restoration reinforced with nano-zirconia particles to improve strength and esthetics
