Effect of glass-ionomer cement lining on postoperative sensitivity in occlusal cavities restored with resin composite - A randomized clinical trial

Abstract

This study investigated the ability of a glass-ionomer cement (GIC) lining to reduce postoperative sensitivity in occlusal cavities restored with resin composite. In addition, the effects of a total-etch and self-etch adhesive on postoperative sensitivity were also compared. Patients who had moderate to deep occlusal caries of at least one molar were recruited. Overall, 103 restorations were placed in 70 participants, with an average age of 22.8 ± 3.8 years. Preoperatively, each tooth was evaluated for cold-stimulated tooth sensitivity using a visual analog scale. If present, tooth sensitivity induced by cold/hot drinks or occlusal function was also noted. Caries was stained with a caries de..
