Aim and Objectives : To evaluate bone regeneration in endodontically induced periapical lesions using Hydroxyapatite, Platelet-Rich Plasma (PRP), and a combination of Hydroxyapatite and Platelet-Rich Plasma for a period of one year. Materials and Methods : Twenty systemically healthy patients of both genders between the ages 20 and 40 years were included. To qualify, the patient had to have a tooth where non-surgical root canal therapy had failed, periapical radiolucency was present, and periapical root end surgery was required. The bony defect had to be confined to the apical area, with the bone covering the entire root surface coronally, with an intact lingual cortical plate. Patients were randomly divided into four groups, with five patients each, as follows: Group I - Replacement with Hydroxyapatite, Group II - Replacement with PRP, Group III - Replacement with PRP and Hydroxyapatite, and Group IV - Control group with no substitutes. The patients were evaluated both clinically and radiographically. Results : The radiographic evaluation revealed that Group I patients showed complete bone regeneration with evidence of a trabecular pattern, at the end of one year, Group II patients showed complete bone regeneration at the end of nine months, Group III patients showed complete bone regeneration at the end of six months, and Group IV patients showed bone regeneration, which was not satisfactory even after one year. Conclusions : The PRP and Hydroxyapatite combination facilitated better and faster bone regeneration when compared to PRP alone.
