1

Microleakage

Is the seeping and leaking of fluids and bacteria between the tooth

2

Interface

Restoration junction

3

Postoperative sensitivity

Is caused by fluids and bacteria moving in and out of the interface between the restoration of the tooth.

4

Percolation

Repeated expansion and contraction of teeth and restorations at different rates results in fluids being sucked in and pushed out at the margins of a restoration.

5

Margins

Are the junction of the tooth and the restoration that is clinically visible.

6

Acid etching

Was the first successful technique for bonding dental materials so tooth structure.Micromechanical bonding technique that was first used to retrain pits and fissure sealants.later when dental composite restorations were developed In the 1960s acid et

7

Enamel tags/micropores

Acid creates a microscopically rough enamel surface, this roughened surface is called .......


9

Biofilm

Is a coating that derives from organisms both large and small.biofilms in the mouth start as molecular coatings and grow into a community of microorganisms(plaque)






15

Primers

Are similar to the low viscosity resins used in enamel bonding systems. Primers see more hydrophilic then resins.

16

Reasin tags

Dentinal tubules



19

Macro mechanical bonding

Is the mechanism by which most glues join two pieces of wood,repair broken toys and do many other things.

20

Micro mechanical bonding

As bonding using surface irregularities smaller than can be seen with the naked eye of felt with an explorer,the result of micro mechanical bonding can be difficult to distinguish from true adhesion.

21

Adhesive

A material that can stick to a flat surface or bond two flat surfaces together
