Compared With Zinc Phosphate Cement Polycarboxylate Cement Has
Zinc phosphate cement has a sedative effect on the tooth. However they may cause pain after their application. Polycarboxylate Cement Cements In Dentistry Dental Cement Cement Dental Zinc phosphate cement is used for luting inlays crowns bridges orthodontic bands and other appliances. . These cements have higher compressive strength and lower solubility when compared with other cements. Zinc phosphate cements lack chemical bond to tooth structure and exhibit a moderate compressive strength 62 to 101 MPa a low tensile strength 5 to 7 MPa and a high degree of solubility 036. Luting cements are a critical but weak link between fixed prostheses and their supporting tooth structures. The aim of this study was to compare the in vitro compressive strength and solubility of a black copper cement with one established restorative material a conventional glass ionomer cement and two temporary restorative materials a zinc phosphate an...
