Abstract

Objectives. The purpose of this in vitro study was to evaluate shear bond strengths and microleakage of seven current-generation dentin adhesive systems.

Methods. Standard box-type Class V cavity preparations were made at the cemento-enamel junction on the buccal surfaces of eighty extracted human molars. These preparations were restored using a microfill composite following application of either All-Bond 2 (Bisco), Clearfill Liner Bond (Kuraray), Gluma 2000 (Miles), Imperva Bond (Shofu), OptiBond (Kerr), Prisma Universal Bond 3 (Caulk), Scotchbond Multi-Purpose (3M), or Scotchbond Dual-Cure (3M) (control). Lingual dentin of these same teeth was exposed and polished to 600-grit. Adhesives were applied and composite was bonded to the dentin using a gelatin capsule technique. Specimens were thermocycled 500 times. Shear bond strengths were determined using a universal testing machine, and microleakage was evaluated using a standard silver nitrate staining technique.

Results. Clearfil Liner Bond and OptiBond, adhesive systems that include low-viscosity, low-modulus intermediate resins, had the highest shear bond strengths (13.3 ± 2.3 MPa and 12.9 ± 1.5 MPa, respectively). Along with Prisma Universal Bond 3, they also had the least microleakage at dentin margins of Class V restorations.

Significance. No statistically significant correlation between shear bond strength and microleakage was observed in this study. Adhesive systems that include a low-viscosity intermediate resin produced the high bond strengths and low microleakage. Similarly, two materials with bond strengths in the intermediate range had significantly increased microleakage, and one material with a bond strength in the low end of the spectrum exhibited microleakage that was statistically greater. Thus, despite the lack of statistical correlation, there were observable trends.

      The type of bonding surface and the type of surface conditioning affects the bond strength of the ceramic to the tooth structure. Restorations bonded to teeth using the total etch technique achieved a bond strength of up to 28 MPa [15] within the enamel and 13 to 20 MPa within the dentin (depending on the adhesive system used) [16,17]. An improved bond strength to dentin can be reached when an immediate sealing of the dentin after the preparation is done [18].

      OptiBond All-In-One contains nanofillers; previous reports20,21 found that the collagen fibril network filters out most nanofillers, holding them at the hybrid layer surface where they act as an intermediate shock absorber. Reduced microleakage scores have been reported for filled adhesives.16,22,23 These differences in chemical composition may have helped create a thicker, more homogeneous resin layer above the hybrid layer using OptiBond All-In-One, which may have improved resistance to microleakage.
