Zinc oxide eugenol ZOE cements

They are extensively used for temporary cementation of crowns and as temporary filling materials because of their therapeutic action. It is claimed that when strengthened some can be used for permanent cementation or as an intermediate restoration, that is a restoration that has a life somewhat greater than a temporary filling material. [Pg.320]

Falling under the heading of metal chelate compounds, the zinc oxide-eugenol (ZOE) cements in the hardened state are essentially zinc phenolates formed by reaction of zinc oxide and eugenol (4-allyl-2-methoxyphenol) in the presence of moisture, embedding... [Pg.959]

The compositional and performance features of the zinc oxide-eugenol and zinc oxide-ort/zo-ethoxybenzoic acid cements were dealt with in Sections II.B.3 and II.B.4. While employed for temporary luting and filling, the ZOE materials find their major use in cavity lining. The fundamentally weak cement materials are usually reinforced for this... [Pg.966]

The ZOE impression paste is essentially a two-paste ZOE cement. One paste is formed by plasticizing the zinc oxide powder with 13 % of mineral or vegetable oil. The other paste consists of 12% eugenol or oil of cloves, 50% polymerized rosin, 20% silica filler, 10% resinous balsam (to improve flow) and 5 % calcium chloride (accelerator). [Pg.335]

This type of cement has been further improved by the substitution of -hexyl van ill ate [84375-71-3] and similar esters of vanillic acid [121 -34-6] and/or syringic acid [530-57 ] for eugenol (93—95). These substituted cements are strong, resistant to dissolution, and, unlike ZOE and EBA cements, do not inhibit the polymerization of resin-base materials. Noneugenol cements based on the acid—base reaction of zinc and similar oxides with carboxyhc acids have been investigated, and several promising types have been developed based on dimer and trimer acids (82). [Pg.475]
