The physical characteristics of resin composite–calcium silicate interface as part of a layered/laminate adhesive restoration

Shear bond strength of universal adhesive systems to a bioactive dentin substitute (Biodentine®) at different time intervals

“…This result is similar to the results of the study of Hanabusa et al [16] , Marchesi et al [17] , and Chen et al [30] , who also reported that using SE or ER technique does not statistically significantly influence bond strength. Hashem et al [25] reported that similar bond strength values between SE and ER modes might be due to the porous structure of the Biodentine ® surface, which may have eliminated the difference between SE and ER techniques. In addition, Biodentine ® which has alkaline propertiesmay reduce the effect of bonding techniques by buffering their acidity [25] .…”

“…The curing contraction of the compomer may lead to stresses, resulting in premature failures in weak Biodentine ® which is in early sensitive phase. This finding should be addressed carefully, as it may affect decisions to immediately place the restoration on Biodentine ® [25] .…”

“…In the present study, a statistically significant difference was observed between 12 min and 24 h groups, and 24 h groups showed higher shear bond values. Hashem et al [25] compared the microshear bond strength of composite resin to Biodentine ® glass ionomer cement and resin modified glass ionomer cementby using early (0.5, 20 min and 24 h) and late (2 weeks, 1 month, and 6 months) aging. They reported a statistically significant increase in the microshear values of late aging groups compared to early aging groups and the highest microshear values were reported in 24 h group.…”

Direct Restoration of Endodontically Treated Teeth: a Brief Summary of Materials and Techniques

“…When used as a dentin substitute material in Bopen sandwich^class II restorations, Biodentine performed similarly to GIC [99]. Although this material was found to be weak in its early phases [100], Biodentine seems promising as a coronal restorative material.…”
