| Abstract |
|
The authors have studied the marginal leakage of various dental cements; Fynal cement (Caulk), Zinc cement (S.S. White) Carbo cement (Shofu, Poly-carboxylate cement), EBA cement (Opotow alumina cement), Propac (G-C's zinc oxide euginol cement), and Super cement (Shofu oxyphosphate zinc cement), by means of penetration of 2% methylene blue solution between orden crown restorations and human teeth in 150 cases. The result revealed as follow
1. None of the cements tested were free from dye penetration.
2. There was a wide difference in dye penetration among the trade brands of dental cement when immersed in dye solution before setting of cements.
3. EBA cement and Carbo cement showed comparatively low grade of dye penetration at the restorative margins. |
