Tooth 25 had a vertical fracture line that extended from mesial marginal ridge and all the way down into the orifice of palatal canal. I thought this was a hopeless case and the patient was very keen to keep the tooth. After dressing with CaOH for two weeks, there was still exudation in palatal canal. Obturation was done after six weeks of CaOH and when both canals were dry. A six-month review showed evidence of peri-apical healing.
