TermDefinition
meaning of desiccate?
to remove all moisture from an item/ dry it out
what is etchant?
an acidic agent used to prepare a tooth surface for the adherence of dental material
what is Eugenol?
a colorless oily liquid made from clove oil that is additive for its soothing qualities
what is a hybrid layer
thin layer created between dentin and the adhesive resin that seals the space between the tooth and restoration
What is micromechanical
is when a material and structure lock onto one another through minute cuttings
meaning of polymerize
the bonding process of two or more monomers to form a polymer
types of stimulus for pulpal responses
- physical stimuli - thermal/electrical - mechanical stimuli - handpiece, traumatic occlusion, grinding - chemical stimuli - acid from dental materials/ saliva - biologic stimuli - bacteria from saliva. or carious structure was not completely removed
what are dental liners?
a thin layer of material that is placed at the deepest portion of the dental preparation, which provides pulpal protection
what do dental liners protect?
they protect the irritations caused by physical, mechanical, chemical biologic elements
what is calcium hydroxide used for?
used as a liner to protect the pulp from chemical irritation
what are glass ionomer liners used for?
to form a strong bond to dentin, sealing the restoration to reduce microleakage and help reduce postoperative sensitivity
what is a dental base ?
an additional layer to protect the pulp
3 different types of pulp protection a base provides
protective - protects the pulp from a large restoration insulating - protects the tooth from thermal shock sedative - soothes the pulp that has been damaged by decay or irritated by mechanical means
4 types of base materials
zinc oxide - eugenol (ZOE) zinc phosphate polycarboxylate glass ionomer
what is a varnish?
a material placed within the entire preparation sealing tubules, reducing microleakage around a restoration, a barrier to protect the tooth
what is a desensitizer ?
used to treat or prevent hypersensitivity that a patient is experiencing from a newly placed direct or indirect restoration
what is the use of a dental etchant ?
critical for the enamel and dentin as it forms a better mechanical bond between the tooth and the permanent restorative material
examples of enamel bonding
-sealants -bonding of orthodontic brackets -resin-bonded bridges -resin-bonded veneers
