Description: Steps in formocresol pulpotomy
The pulp chamber is dried with sterile cotton pellets. Next, a pellet of cotton moistened with a 1:5 concentration of Buckley’s formocresol and blotted on sterile gauze to remove the excess is placed in contact with the pulp stumps and allowed to remain for 5 minutes.
Because formocresol is caustic, care must be taken to avoid contact with the gingival tissues. The pellets are then removed, and the pulp chamber is dried with new pellets.
A thick paste of hard-setting zinc oxide–eugenol is prepared and placed over the pulp stumps.
The tooth is then restored with a stainless steel crown.
