Q

4 functions of dental pulp?

A
  • formative: produces dentine that surrounds it
  • nutritive: nourishes dentine
  • protective: carries nerves for sensitivity
  • reparative: produces new dentine in relation to wear and insult
2
Q

pulp protection: protect from?

A
  • chemical attack: from constituents in restorative materials
  • thermal shock: heat from cavity prep
  • galvanic effects: metal corrosion
3
Q

properties of ideal pulp protector?

A
  • radiopaque
  • compatible with wide range of restorative materials
  • obtundant; reduce pain
4
Q

general methods of pulp protection?

A
  • varnishes

- cavity bases

5
Q

name the 5 types of cavity bases used in pulp protection

A
  • calcium hydroxide: dycal
  • polycaboxylate cements: poly F
  • zinc oxide eugenol: kalzinol
  • zinc phosphate
  • glass polyalkanoate: vitrebond
6
Q

bonded restorations: what is used in resin composite restorations?

A
  • acid etch for enamel

- dentine bonding agent

7
Q

bonded restorations: what is used in dental amalgam?

A
  • vitrebond
  • acid etch
  • scotchbond
  • rely-x ARC (resin cement)
8
Q

techniques of cavity lining in bonded restorations: what do these methods help with?

A
  • prevent ingress of fluids and bacteria

- protects pulp

9
Q

what to use: if cavity is of ideal depth?

A

no lining

10
Q

what to use: if cavity is slightly deeper?

A
  • dycal
  • acid etch
  • dentine bonding agent (if composite) OR vitrebond (if amalgam)
11
Q

what to use: if cavity is grossly deep?

A

dycal
vitrebond
* do not extend lining to cavity periphery, only dentine on overlying pulp should be covered
