The authors experienced a case of crown fracture of 〓 due to trauma in a girl, eight years old. 1) Clinical findings showed fracture of the crown 〓 at about the mid-point and exposure of the pulp. Time elapsed before treatment was short and the surface of the exposed pulp had little bleeding and showed fresh blood color. 2) No mobility or pulpation tenderness was found. In radiographic findings, the root was incomplete and the root apex was open like a funnel. 3) For treatment, pulpotomy was performed and the course was observed. The crown was restored with a resin jacket crown with the pin retained in the dentin. 4) Fourteen months after operation, no abnormal findings are seen clinically. Radiograms showed further growth of the root and apical closure in progress. However, radiolucency of the pulp chamber was observed and pulpotomy at the middle portion of the root canal was performed again in consideration of prognosis. 5) At present, fourteen months after operation, prognosis is favorable.
