About

The purpose of this study is to observe the effects of glass-ionomer cement (GIC) lining on risk of pulpal complications in deep occlusal cavities with resin-based restorations.

Full description

Fifty three patients aged 18-30 years who had one or two deep occlusal carious lesions (≥ 3 mm in depth) in molars were recruited. Dental caries was removed and the prepared cavity was restored with resin composite using one of two restorative procedures: (1) without GIC lining; (2) with (resin-modified) GIC lining. Restored teeth were evaluated for any pulpal complications (subjective symptoms, objective signs or loss of tooth vitality) at one month (baseline), one year and two years after restoration.

Enrollment: 53 patients

Sex: All

Ages: 18 to 30 years old

Volunteers: Accepts Healthy Volunteers
