- Abstract
Purpose: This study qualitatively assessed, dentine surfaces that have been treated with two tubule-occluding toothpastes (Sensodyne Rapid-Relief and Colgate Pro Relief) and subsequently with a total etch or self- etch DBAs in an attempt to ascertain the effect on dentine surface characterization. Methods: Eight 2 mm dentine discs were obtained from human teeth, halved, treated with citric acid, and subjected to brushing with either toothpaste. The brushed dentine surfaces were treated with either a total etch regimen [phosphoric acid (H3PO4) and SingleBond (SB)] or the self-etch product [SingleBond Universal (SBU)]. Non-brushed halves were treated in the same manner for comparative purposes. Results: Both toothpastes provided a high degree of occlusion of dentine tubules. Precipitates of the Sensodyne product showed resistance to etching with H3PO4, while H3PO4 readily removed precipitates of the Colgate Product. Both SB and SBU provided good coverage of the experimentally treated dentine surfaces compared to control dentine surfaces treated with the same DBAs. Conclusion: SEM examination revealed varying amounts of precipitates present during the stages of the bonding procedures.
