Pulpotomy

The pulpotomy is the amputation of the coronal portion of the diseased pulp, preserving the vitality and function of the remaining radicular pulp. 
How do we practice Pulpotomy? What we do at school is this: They give us a plastic phantom where you can remove every teeth. If we want to the first temporary molar we just need to add wax so when we open we will find the "pulp", the wax pulp in this case.

Preparation:
  1. Anesthesia and isolation. Like always we have to isolate the teeth and open the pulp chamber. Do not forget the floss!
  2. Open the cavity and remove all the decayed dentine. If we remove all the decay before to expose the pulp it reduces the bacterial contamination.
  3. Remove the roof of the pulp chamber. It shouldn't be outstanding of dentine on the pulp roof or pulp horns.


  1. Control the bleeding with cotton balls with physiologic serum. The bleeding must yield in 5 minutes and be bright red.
  2. Fixing the root pulp lightly dampened with formocresol in a cotton, and finally pressing with another dry cotton 5 more minutes.
  3. If we explore the mummified pulp: black, without haemorrhage.
  4. The bottom of the cavity filling with IRM, Intermediate Restorative Material (zinc oxide with eugenol). Adapt the IRM to the ground of the cavity and the severed areas attacking with cotton balls dipped in zinc oxide.
  5. Final sealing of the tooth.
    1. Anterior teeth: IRM + glass ionomer layer and finally reconstruction of the restoration.
    2. Posterior teeth: metal crown that prevents leaks, fractures and secondary decays.
