Introduction: Glass ionomer cements (GICs) are widely used in clinical dentistry due to their advantageous properties. However, they present inferior physical and mechanical properties compared to resin composites. Aim: Clinical evaluation of chemically cured conventional glass ionomer after light-emitting diode radiant heat enhancement. . Methodology: Eighteen healthy patients with 36-second molar teeth will be selected where each patient should have two oclusso- mesial cavities. Standardized oclusso- mesial cavities will be prepared for all the selected teeth, for each patient the first tooth will be restored with chemically cured conventional GICs without any enhancement (M1 group). Meanwhile, the second tooth will be restored by chemically cured conventional GICs that enhanced with radiant heat (LED) (M2 group). functional and biological criteria of each restoration will be clinically evaluated at 4 time points
