The purpose of this study was to determine whether there were differences in shear bond strength to human dentin using
IDS technique compared with DDS. Forty freshly extracted human molars were and devided into 4 groups. The control
group specimens were, on the morrow of tooth preparation, light-cured after application of dentin bonding agent and
cemented with resin cement. The IDS/SE(immediate dentin sealing, ClearfilTM SE Bond) and IDS/SB (immediate dentin
sealing, AdapterTM Single Bond 2) specimens were, on the morrow of tooth preparation, light-cured after application of
dentin bonding agent(ClearfilTM SE Bond and AdapterTM Sing Bond 2, respectively), whereas DDS specimens were not
treated with any dentin bonding agent. IDS/SE, IDS/SB and DDS specimens were thermocycled. Following that delay,
specimens were cemented with resin cement. The dentin bonding agent was left unpolymerized until the application of
porcelain restoration. Shear bond strengths were measured using a universal testing machine. Specimens also were evaluated for mode of fracture using an optical microscope. The mean shear bond strengths of control group and IDS/SE groups were not statistically different from one another. The bond strength of IDS/SE group had a significantly higher mean than that of DDS group. There was no significant difference in the mean shear bond strength between IDS/SB(4.11MPa) and DDS group. The evaluation of failure modes indicates that most failures in the control group and IDS/SE groups were
mixed, whereas failures in the DDS group were interfacial. When preparing teeth for indirect ceramic restoration, IDS with
ClearfilTM SE Bond results in improved shear bond strength compared with DDS.
