DMS Summary Flashcards
List temp restorative materials (3)
Cavit
Coltosol
Kalzinol
What type of cements are cavit/coltosol?
ZO(E free) - won’t affect final set
F release
What type of cement is Kalzinol
ZOE - affects set with composite
Antimicrobial - soothes pulp
Amalgam constituents
Silver, tin, copper, mercury
Disadvantages of amalgam
Retentive prep
High thermal conductivity
Lichenoid reactions
Creep/ditch/corrosion
Does not bond to tooth - micro leakage
Mercury toxicity
Composite constituents
Resin - bis RMA
Filler - glass
Camphorquinone - photoinitiator
Silane coupling agent
Disadvantages of composite
High thermal expansion
Moisture control
Polymerisation shrinkage
Advantages of composite
Low thermal conductivity
Aesthetic + bonds to tooth
Examples of GI
FUJI/Chemfill/RIVA
GI constituents
Acid - polyacrylic, tartaric
Base - silica, alumina
Different classes of GI
- luting cement (aquacem)
- restorations (RIVA)
- liner (vitrebond)
- core build-up
GI setting reaction
Dissolution - H ions diffuse into glass
Gelation - Ca ions form crosslinks
Hardening - Al forms trivalent bonds (7 days to set)
RMGI constituents
Polyacrylic acid
Barium glass
Liquid - HEMA, tartaric acid, water
RMGI disadvantages
Polymerisation contraction
HEMA hydrophilic - swelling
HEMA toxic to pulp - monomer leaching risk
Properties of sCAOH
High ph - stimulates fibroblasts for tertiary dentine formation
Recalcifies demineralised dentine by stimulating pulpal cells
Disadvantages of sCAOH
Soluble if not protected
Cytotoxic - can kill pulp cells
List intracranal medicaments (3)
Ledermix
Odontopaste
nsCAOH
Indications for ledermix/odontopaste
Pulpitis
Abx+antinflammatory
Who do we not use odontopaste for?
Pregnant pts
