Clinical Evaluation of New Dental Adhesive in Posterior Composite Restorations

PURPOSE: To evaluate the clinical efficacy of a new All-in-One dental adhesive iBOND Self Etch (iBSE, Heraeus Kulzer GmbH, Wehrheim, Germany) in posterior Class I and II composite restorations compared to GLUMA Comfort Bond + Desensitizer (Gluma) of Heraeus Kulzer in a split mouth study design. METHODS: Restorations were placed in 60 teeth of 21 subjects (5 males, 16 females) with Venus (Heraeus Kulzer) according to manufacturer's instructions, with ≥2 and ≤4 restorations/subject. All restorations were photographed and radiographed, and impressions were taken. There were 10 Class I and 20 Class II restored with iBSE and 11 class I and 19 class II with Gluma. Restorations were evaluated following modified Ryge criteria. The parameters were anatomic form, color match, marginal integrity and discoloration, surface staining, retention, fracture, secondary caries, polishability, and changes in adjacent teeth. Soft tissue health and post-operative sensitivity were evaluated using Loe-Silness gingival index and visual analog scale, respectively. The two-sample t-test was used to determine if two bonding systems are equal. RESULTS: iBSE was easy for clinical application. The baseline evaluation found no restoration lost or showing marginal staining. All 60 restorations had excellent condition for all parameters. Two subjects (one for each group) exhibited postoperative air/water sensitivity. The color match of 4 restorations (2 for each group) was less than ideal. Most of the subjects were pleased with the results. In general, all the restorations were judged to be clinically satisfactory. No significant differences (p=1.00) were detected in all parameters examined between the two groups. CONCLUSIONS: iBSE and Gluma are comparable in clinical performance. iBSE is easy to use and provides an acceptable level of clinical performanace for posterior class I and II restorations.
