Superior sealing Applying ParaBond Adhesive prior to cementation with ParaCore effectively seals and protects the restoration against marginal microleakage to minimize the risk of postoperative complications. An independent In-Vitro study 1 compared the amount of microleakage present following cementation of
all-ceramic crowns using different composite luting cements. Cross-sectioned human molars demonstrated significant differ- ences in the amount of dye penetration (marginal microleakage) after thermal cycling.

Cementation with ParaBond
The total score between 0 (no leakage) and 8 (total leakage across preparation) was generated by adding scores from the left & right sides together. The Mann- Whitney non-parametric test showed ParaCore with statistically significant better scores (e.g. less dye leakage) than: seT (P < 0.001) Maxcem Elite (P = 0.002)
no leakage leakage from crown margin reaching axial wall leakage on axial wall, but not occlusal surface leakage as far as occlusal surface leakage to mid point of occlusal surface
