Cervical gap formation in class II composite resin restorations. 1984

L Ehrnford, and T Dérand

In vitro, class II restorations were made in three materials, one regular, one microfilled composite and one experimental condensable composite with a porous filler. The aim was to study cervical marginal gap widths appearing in composite restorations when acid etch technique was used. The gaps were about 35 micron for the two contemporary materials and about 10 micron for the experimental one.

UI	MeSH Term	Description	Entries
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.

D002627	Chemistry, Physical	The study of CHEMICAL PHENOMENA and processes in terms of the underlying PHYSICAL PHENOMENA and processes.	Physical Chemistry,Chemistries, Physical,Physical Chemistries
D003188	Composite Resins	Synthetic resins, containing an inert filler, that are widely used in dentistry.	Composite Resin,Resin, Composite,Resins, Composite
D003737	Dental Cavity Preparation	An operation in which carious material is removed from teeth and biomechanically correct forms are established in the teeth to receive and retain restorations. A constant requirement is provision for prevention of failure of the restoration through recurrence of decay or inadequate resistance to applied stresses.
