The purpose of this study was to evaluate the clinical effects of a new, l-tricalcium phosphate (β-TCP) grafting material on osseous defects in jaws. Sixty-seven patients were treated by grafting with β-TCP which was blockshaped (1 cm3) From among them, 4 patients could not be followed up. The followed up cases included 47 radicular cysts, 8 follicular cysts, 3 odontomas, 3 residual radicular cysts, 1 globulomaxillary cyst, and 1 periodontal cyst. The results were classified according to criteria for evaluating efficacy: Very effective, Effective, Not effective, and Harmful. Forty cases (63.5 %) were classified Very effective or Effective. The largest defect was the radicular cyst which was grafted by the 4 blocks. This case was classified Very effective. In all cases, a side effect due to the grafting material did not occur. These results suggested that the jS-TCP block is a useful grafting material because of its potential for osseous repair, if the cases are as follows: 1. In infective cases, the source of infection must be removed, completely. 2. The osseous defect is no or small bony perforation. 3. The size of osseous defect is smaller than 4 cm3.
