Q

How do you complete a partial pulpotomy?

A
  • radiographic assessment
  • LA / rubber dam
  • clean area with water and disinfect with sodium hypochlorite
  • remove 2mm of pulp with hi-speed round diamond bur

Q

How do you complete a full coronal pulpotomy?

A
  • begin with a partial pulpotomy
  • if haemostasis not achieved or pulp necrotic proceed to full coronal
  • remove all of coronal pulp
  • place dycal in the chamber
  • seal with GI liner and place composite restoration

Q

How are immature incisors root treated?

A
  • no apical stop, therefore specialist treatment required
  • MTA or BioDentine placed at apex of canal to form cement barrier (apical plugging)
  • regenerative endodontic treatment to encourage hard tissue formation (encourage bleeding, not routine)
