Microleakage between glass-ionomer cement and composite resins. 1992

This study investigated the microleakage between glass-ionomer cement and Silux or Herculite with and without Scotchbond 2. Cavities were prepared in polymerized composite resin samples and "restored" with a glass ionomer cement with and without Scotchbond 2. The samples were thermocycled and immersed in 0.05% crystal violet solution for 2 hours, then embedded in clear casting resin, sectioned, and examined with an optical microscope. The results indicated that a high degree of dye penetration was found in samples of GC and Silux, and GC and Herculite without Scotchbond 2. The use of Scotchbond 2 significantly reduced the degree of dye penetration, but did not completely eliminate dye penetration.

D001840	Dental Bonding	An adhesion procedure for orthodontic attachments, such as plastic DENTAL CROWNS. This process usually includes the application of an adhesive material (DENTAL CEMENTS) and letting it harden in-place by light or chemical curing.

D003188	Composite Resins	Synthetic resins, containing an inert filler, that are widely used in dentistry.	Composite Resin,Resin, Composite,Resins, Composite
D003736	Dental Cavity Lining	An inner coating, as of varnish or other protective substance, to cover the dental cavity wall. It is usually a resinous film-forming agent dissolved in a volatile solvent, or a suspension of calcium hydroxide in a solution of a synthetic resin. The lining seals the dentinal tubules and protects the pulp before a restoration is inserted.

D003793	Dental Restoration, Permanent	A restoration designed to remain in service for not less than 20 to 30 years, usually made of gold casting, cohesive gold, or amalgam.

D003804	Dentin	The hard portion of the tooth surrounding the pulp, covered by enamel on the crown and cementum on the root, which is harder and denser than bone but softer than enamel, and is thus readily abraded when left unprotected.

D005899	Glass Ionomer Cements	A polymer obtained by reacting polyacrylic acid with a special anion-leachable glass (alumino-silicate). The resulting cement is more durable and tougher than others in that the materials comprising the polymer backbone do not leach out.

D017438	Bisphenol A-Glycidyl Methacrylate	The reaction product of bisphenol A and glycidyl methacrylate that undergoes polymerization when exposed to ultraviolet light or mixed with a catalyst. It is used as a bond implant material and as the resin component of dental sealants and composite restorative materials.
