Zirconomer-P Versus RMGI for Proximal Restorations in Primary Molars

Clinical trial comparing two tooth-colored restorative materials for treating cavities between the teeth of primary molars in children aged 4 to 7 years. The study will compare zirconia-fortified glass ionomer (Zirconomer-P) with resin-modified glass ionomer (RMGI) to evaluate their clinical performance, including the condition of the restoration, marginal adaptation, proximal contact, occlusion, wear, fracture, retention, and development of caries at the restoration margin. Children will be followed for up to 18 months after treatment.
