Abstract
Objectives: To evaluate the effect of pulpal pressure and immediate (IDS) or delayed dentin sealing (DDS) technique on microtensile bond strength (μTBS) of an adhesive resin cement to exposed human dentin.
Methods: Fifty extracted human third molars were divided into 2 groups: pulpal and non-pulpal pressure (PP, NP), which represented vital and non-vital tooth. Each group was divided into 5 subgroups: direct restoration (control), DDS technique and 3 IDS techniques, [etch-and-rinse (TE), self-etching (SE) and universal adhesive (U)]. The hydrostatic pressure of 20 cmH2O was applied prior to adhesive application in PP groups during the experiment. The self-adhesive resin cement was used to bond a composite disc onto dentin for all groups. Ten small square beams from each group were fabricated and collected for μTBS testing and mode of failure monitoring.
Results: All three IDS groups yielded a significantly higher μTBS than control and DDS groups in both pulpal conditions. DDS groups yielded the lowest μTBS. The presence of pulpal pressure caused a significant reduction
of μTBS in TE and DDS groups.
Conclusions: The IDS technique could produce higher μTBS than the DDS and direct restoration technique in both pulpal conditions.
