composite fillings

the curing light is used for what procedure/ material

Triturator

used to combine the dental alloy and with mercury

zinc phosphate cement

fine grain that easliy flows into the small internal irregularities of the restoration

medium grain powder which can be used as a temporary restoration in posterior teeth

zinc polyacrylate cement

adheres directly to tooth structure through chelation which is a chemical reaction between two substances. it can be used to attach orthodontic brackets to tooth structure

zinc oxide eugenol cement

contains eugenol which is found in clove oil

temporary dental cement

used for temporary crowns while a patient is waiting on their permanent crown

properties of glass ionomer cements

has ability to bond to enamel and dentin

high strength and low solubility

low film thickness

biocompatible with tooth pulp

can be used as a base

calcium hydroxide

a substance that is placed in the deepest part of cavity preparation closest to the pulp where it stimulates formation of secondary dentin

a cement base

what is applied to the cavity preparation after a varnish is placed

silver, tin, copper, zinc

what is the chemical composition of amalgam?

No

Do dental amalgams adhere directly to tooth structure?

to improve the retention between the tooth structure and the restoration

what are bonding agents used for?

informed consent

requirement of parent or guardian to sign a form granting consent to perform any treatment

reassurance, restraint, sedation

methods used for behavior management acceptable for pediatric patients

space maintainers

used when premature loss of primary teeth takes place. these devices serve to maintain space within the dental arch until eruption of permanent teeth takes place

pulpotomy

performed when decay has caused an invasion into the pulpal chamber of a primary tooth the pulpal chamber tissue is removed leaving the pulpal canal, the vacant chamber is treated with formocresol and zinc oxide eugenol cement is mixed into a putty and condensed into the pulp chamber a stainless steel crown is then placed on top of the treated tooth

nitrous oxide

inhalation sedation, a nitrous oxide, oxygen mix inhaled via the nose. can be used as an anxiety reducer for children during dental treatment offers fast onset and recovery with minimal to no side effects

pulpectomy

performed on permanent and primary teeth and involves removing both the pulp chamber and the pulp canals

general anesthesia

patient looses all protective reflexes, ability to obey commands and maintain an open airway

zinc oxide eugenol

placed within the vacant chamber of a primary tooth following pulp irradication. this is the substance that is mixed into a ball during lab on the glass slab

sealants

a preventative measure used to seal hard to clean, naturally deep narrow fissures on the chewing surfaces of primary and permanent posterior teeth

formocresol

antibacterial medicament to control hemorrhage (bleeding) within the chamber

stainless steel crown

placed after a pulpotomy if a large amount of tooth structure is removed

matrix band

used for a class II restoration which includes medial or distal

amalgum resoration

a triturator is used to activate the amalgam, carving instrument, high speed handpiece and a matrix band if its class II

glass ionomer cement

used for permanent cementation of dental prosthetics such as crowns and bridges and as a restorative filling material

breaking open a pre measured capsule of metal alloy and mercury

how is amalgam activated?
