Aim: to evaluate and compares the healing clinically and radiographically following periapical surgery with and without using hydroxyapatite graules. Materials and Methods: Twenty patients were selected for the study & the nature of healing is compared with that of conventional periapical surgery. In the present clinical study chitra hydroxyapatite granules, a freeze-dried hydroxyapatite, is used to fill the osseous defects following periapical surgery. Following surgery all patients were assessed both clinically & radiographically for a period of nine months. Results: On clinical evaluation the test group did not show any significant immediate or delayed local tissue reactions. Radiographically in the follow up period of 6 - 9 months the bone graft became indistinguishable from the surrounding bone which indicates complete bone regeneration. Where as in the control group ever after 9 months the radiographs showed inadequate bone fills. Conclusion: The bone regeneration following periapical surgery can be facilitated by using bone graft. Hydroxyapatite is found to be very effective alloplastic material. Based on this study it might be concluded that in large bone destruction caused by periradicular lesion bone regeneration can be facilitated by effective bone replacing materials like hydroxyapatite.
