dental materials and pediatric dentistry

what procedures/dental materials a curling light is used for

composite only - not needed for amalgam it sets on its own

what extra instruments are needed when doing a class II restoration vs class I

matrix bands is used for a class II which includes mesial or distal

what extra instruments are needed for an amalgam restoration compared to a composite?

triturator to active amalgam, carving instrument, high speed handpiece and matrix band if its a class II

what is a glass ionomer cement most used for?

for cementaion of crowns and bridges because it chemically bonds to tooth structure

what is a mechanical method of combining dental alloy and mercury

trituration

what are bonding agents (glue) used for

to improve the retention between the tooth structure and the restoration

what is a pulpotomy

performed when decay has caused an invasion into the pulpal chamber of the primary tooth

what is formocresol used for

to control hemorrhage within the chamber

know the steps during a pulpotomy and what is used during the procedure

a. remove pulpal chamber tissue leaving pulpal canal

b. vacant chamer is treated with an anti baterial medicament (formocresol or hemodent) to control hemorrhage withith the chamber

c. zinc oxide eugenol cement is mixed into a putty and condensed into the pulp chamber

d.stainless steel crown is then placed on top of treated tooth

what is needed after a pulpotomy if a large amount of tooth structure was removed

a crown

what is calcium hydroxide used for

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

zinc phosphate cement

powder and liquid mixed on a cool glass slab

zinc polyacrylate cement

adheres directly to tooth structure through chelation which is a chemical reaction bewteen substances (attachs orthodontic brackets)

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

what are the properties of glass ionomer cements

1.has ability to bond enamel and dentin

2.high strength and low stability

3.low firm thickness

4.biocompatible with tooth pulp

5.can be used as a base

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

base

what is the chemical composition of amalgam

1.silver (Ag)

2.tin (Sn)

3.copper (Cu)

4.zinc (Zn)

dental sealants

most likely candidates are first and second year molars and premolars specifically teeth that feature deep, narrow pits and fissures on their chewing surfaces

does dental amalgam adhere directly onto the tooth structure

they do not adhere to the tooth structure

what is nitrous oxide and its side effects

a mixture of nitrous and oxygen there are minimal to no side effects

when a pulpotomy needs to be completed

when decay has caused an invasion into the pulpal chamber of primary tooth

space maintainers purpose and when needed

device 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

3 methods of behavior management acceptable for pediatric patients

1.reassurance

2.restraint

3.sedation

when is informed consent and when is it needed

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

what substance is placed within the vacant chamber of a primary tooth following pulp irradication

zinc oxide eugenol- this what you mix into a ball during lab on a glass slab

what type of sedation causes a loss of all protective reflexes including ability to obey commands and maintain an open airway

general anesthesia
