Arms Assigned Interventions
Active Comparator: Glass-ionomer cement lining
Presence of glass-ionomer cement lining in posterior resin composite restorations.
Procedure: Glass ionomer cement lining

Other Name: Vitrebond (3M ESPE, St. Paul, MN, USA)
No Intervention: No glass-ionomer cement lining
Absence of glass-ionomer cement lining in posterior resin composite restorations

Detailed 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.

Ages Eligible for Study:   18 Years to 30 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Deep dental caries on occlusal surfaces of molar teeth

Exclusion Criteria:

  • Shallow and moderate-depth caries
  • Caries exposed pulp
