PURPOSE: To evaluate the clinical effectiveness of the Self-Etch dental adhesive iBOND Self Etch (iBSE, Heraeus Kulzer GmbH, Wehrheim, Germany) in posterior Class I and II composite restorations compared to the Etch & Rinse-system GLUMA Comfort Bond + Desensitizer (Gluma) of Heraeus Kulzer over a 24-month period in a split mouth study design. MATERIALS AND METHODS: Sixty restorations (30/group) were evaluated in 21 subjects (16 females, 5 males) with ≥2 and ≤4 restorations/subject. There were 10 class I and 20 class II restored with iBSE and 11 class I and 19 class II with Gluma. The marginal integrity and discoloration, surface staining, retention, fracture, secondary caries, anatomic form, color match, polishability, and changes in adjacent teeth were recorded following modified Ryge criteria. Post-operative sensitivity and soft tissue health were evaluated using a visual analog scale and the Löe-Silness gingival index, respectively. All restorations were radiographed and photographed. RESULTS: The 6-month evaluation indicated that all restorations (60) had excellent marginal adaptation or marginal integrity. No soft tissue health changes were observed. The color match of six (three/group scored at Bravos) restorations (10.0%) was less than ideal, being a lighter shade than the surrounding tooth structure. One class II-restoration (3.3%) of Gluma showed small marginal discoloration and received the Bravo score. No restorations in iBSE showed marginal discoloration. One restoration of Gluma received the Bravo for the anatomic form due to wear of the small occlusal area. No restorations were lost. No secondary caries, fractures or postoperative sensitivity from air/water were observed. CONCLUSIONS: Based on the 6-month findings of this study, iBSE and Gluma are comparable in clinical performance. The self- etching adhesive iBSE when used with Venus offers acceptable clinical results for posterior class I and II restorations.
