Clinical Evaluation of a Restorative Glass Ionomer and a Bulk-fill Composite Resin

Clinical Evaluation of a Restorative Glass Ionomer and a Bulk-fill Composite Resin

The clinical performance of a restorative glass ionomer and bulk-fill resin composite in class II restorations will be evaluated and compared. After recruiting participants with at least 2 approximal caries lesions, all restorations will be placed by a single clinician. All caries lesions will be removed before restoring. Cavities will be divided into two groups: a restorative glass ionomer [Equia Forte HT, GC, Tokyo, Japan (EHT)] and bulk-fill composite resin [SonicFill2, Orange, CA, USA (SBF)] All restorative procedures will be conducted according to manufacturers' instructions. Restorations will be scored using modified United States Public Health Service (USPHS) criteria after a week (baseline) 6, 12, 24, 36 and 48 months. Descriptive statistics will be performed using chi-square tests.

Inclusion Criteria:

• age range will be 18 to 65
• patients should have at least 2 approximal caries lesions require restoration
• healthy periodontal status
• a good likelihood of recall availability

Exclusion Criteria:

• poor gingival health
• adverse medical history
• potential behavioral problems
