Administer local anesthetic

• Establish rubber dam isolation

• Rinse the tooth with saline

• Remove 2 mm of pulp tissue using a diamond bur on high-speed handpiece

• Provide copious water spray during procedure

• Check to ensure healthy pulp has been reached

• Place cotton pellet with sodium hypochlorite on pulp until bleeding stops

• Place calcium hydroxide or MTA over exposed pulp

• Place a layer of glass ionomer cement over the dentin and pulp medicament

• Restore with composite resin or reattach crown fragment

This is mostly done in case of enamel-dentine-fracture (dental trauma), where you have a very thin dentin structure covering the pulp and you do the pulpotomy in sake of having a better pulp diagnosis or when you have exposed pulp. It's called Cvek Pulpotomy.
