|
Pulp protection |
Used as base or liner to protect pulp when Dentin is thin |
|
|
Liquids used |
Eugenol Phosphoric acid Polyacrylic acid |
|
|
Eugenol |
Organic weak acid Has oil of cloves Is an obtundent |
|
|
Phosphoric acid |
2/3 phosphricbacjd and 1/3 water Irritating Water affects it If cloudy it’s bad |
|
|
Polyacrylic acid |
30-50% polyacrylic acid and very viscous Does not form individual drops |
|
|
Powder/liquid ratios and systems of cements |
Bases are thicker than luting Mix too long then thick and thennwont seat |
|
|
ZOE Cement |
Zinc oxide with Eugenol May be reinforced or un reinforced Not great strength Good for pulp If paste to paste it’s dispensed at equal lengths If powder to liquid then scoop and drops and forced together. Big then small increments 1 inch of material for cement Dough ball for base Clean up immediately |
|
|
Zinc phosphate cement |
Zinc oxide with phosphoric acid Powder and liquid Comes in shades Irritating to pulp Used with liner or varnish Dispensed with scoops And drops Exothermic Used with glass slab Mix a lot of small sections 1 inch string for Luting Dough ball for base Clean quickly or with baking soda |
|
|
Glass ionomer cements |
Glass powder with aqueous poly acrylic acid Sometimes used as temp restoration or lg base Powder/liquid-drops and scoop Capsule in amalgamator Paste to paste with equal lengths Strongest and least soluble. Adhesive, releases fluoride and good bio compatability Quick mixing time Used while glossy |
|
|
Polycarboxylate cement |
Zinc oxide with polyacrylic acid 1st used Very little leakage Not very acid and good as luting and base Not very strong and moderate solubility Mixed same ass glass ionomer |
|
|
Composite cements |
Or resin cements Very small particle sizes Chemically and light cured and and dual cure |
|
|
Liner |
Thin to protect pulp from chemical irritation May stimulate secondary Dentin and release fluoride No thermal protection |
|
|
Zinc phospate mixing |
Exothermic so mix on glass pad in big motions Follow instructions 15 seconds for each increment 1 inch strong for luting and more liquid than powder Putty ball for base and more powder than liquid. Setting is 5-9 minutes Clean with baking soda |
|
|
Glass ionomer mixing |
Kind of kind to pulp Release fluoride Powder to liquid like other things Capsule in amalgamator Paste to paste is equal strings and mix Scoop and drop the correct amounts Mix powder and liquid 15-30 seconds of mixing time Use while glossy .5 inches of stretch for luting A little ball for base Setting time is 7 minutes Clean with soap and water |
|
|
Zinc oxide Eugenol mixing |
Soothing to pulp Scoop and drop Mix half of powder at first. Use quick motions Make a putty 1.5 minutes for mixing Set from 2.5-3.5 Clean with alcohol |
|
|
Which cement is accelerated by humidity |
Calcium hydroxide and ZOE |
|
|
What is used to calm pulp |
Zoe |
|
|
Which is mixed slowly to get rid of heat |
Zinc phosphate |
|
|
What should be used before glossy goes away |
Glass ionomer |
|
|
Which is available in a capsule |
Glass ionomer |
|
|
Cements used for caries |
Glass ionomer and ZOE |
|
|
Zoe does not have |
Fluroride release |
|
|
Base |
Strong and thick Thermal insulation Support restoration and may release Fluoride May be irritating to pulp and used with liner |
|
|
Which cement is most soluble |
Zoe |
|
|
If glass ionomer is mixed too slowly it make it |
Thick |
|
|
Cements are ... soluble than restoration |
More |
|
|
Which cement should be mixed wide to reduce exothermic reaction |
Calcioum hydroxide |
|
|
What is an additive to glass powder. |
Fluoride |
|
|
Cement of choose for luting ceramic restorations |
Composite |
|
|
Drawback of using polycarboxylate cement |
Lack of strength |
|
|
ZOE May be hard for |
Temp restorations, intermediaste bases and luting temp crowns |
|
|
Temp restoration |
May be used in an emergency If a diagnosis isn’t figured out use a base |
|
|
Temp material as base |
When part of temp material is shaved down to become a base of a Perminant restoration |
|
|
Carried control |
Used with a patient that has more than 10 lesions. Remove decay, place temp restorations, improve hygiene, change diet, and do fluoride |
|
|
Varnish |
Resins disolved in a solvent Painted on and then the solvent Evaps and leaves resin. Used to seal preps Protects pulp from irritation Can’t protect against thermal irritation Not used with composite |
|
|
Order of placement |
Bioactive, adhesive and irritations |
|
|
Formulation |
Powder/liquid Liquid is acid Powder is base |
|
|
ZOE May be used for |
Temp restorations, intermediaste bases and luting temp crowns |
