Rewetting Strategies for Bonding to Dry Dentin with an Acetone-Based Adhesive.

Finger, Werner J.; Balkenhol, Markus

Purpose: The objective of this study was to investigate the effect of rewetting agents on bonding to etched and air-dried dentin. Materials and Methods: For shear bond strength testing (SBS), the proximal surfaces of 90 molars were ground on wet SiC paper to prepare them for resin composite bonding with Gluma One Bond (Heraeus Kulzer. Germany). Dentin cavities were cut (0 3.5 mm, 1.5 mm deep) in 60 molars and restored with Gluma One Bond/Charisma for evaluation of the marginal performance (MGW). The adhesive was applied on acid-etched and rinsed dentin after the following pretreatment techniques: A: moist; B: 15 s air dried; C through F: 15 s air dried, followed by 30 s rewetting with C: water; D: 35% HEMA; E: Gluma Primer; F: 5% glutardialdehyde; G through J: as C through F, but followed by 15 s air drying. SBS data were analyzed with ANOVA and Tukey’s test, and MGW with Kruskal- Wallis and Mann-Whitney U-test ˇct = 0.05). Results: Shear bond strengths of groups A and B were 20.3 and 1.1 MPa. respectively. The Tukey ranking of SBS results was ˇAOD-E] > [OD=E] > [C=D=I] > H > [F=J] > [B=GJ. Groups A, C, D, E, H, and I with 3 or 4 gap-free restorations each showed no differences in MGW (p > 0.05). In contrast, no gap-free specimens were found in groups B, F, G, or J, and marginal gaps were significantly larger (p < 0.05). Conclusion: Rewetting of dried dentin with water, 35% HEMA, or Gluma Primer resulted in effective bonding. Excessive drying after rewetting had no compromising effect on adhesion in the HEMA- and GLUMA- primed groups, whereas the water and glutardialdehyde-treated groups showed poor bonding.
