The present study evaluates and compares the effectiveness of Simvastatin (SIM), Hydroxyapatite (HA), and platelet-rich fibrin (PRF) in bone regeneration of periapical defects.
Thirty-nine patients were selected and randomized into three groups, Group 1: HA (n = 13), Group 2: PRF (n = 13), Group 3: SIM (n = 13). After completion of RCT and apicoectomy, the grafts were placed locally in the defect and sutured.
At the end of twelve months, postoperative symptoms and radiographic analysis assessed the outcome of the treatment
Intragroup analysis of CBCT- Periapical Index (PAI) scores at 6th and 12th month revealed a significant change in the SIM group (p = 0.018 and 0.001 respectively), compared to PRF (p = 0.026 and 0.001 respectively) and HA (p = 0.053 and 0.039 respectively). Intergroup analysis of change in the level of CBCT-PAI score was highly significant (p = 0.003).
SIM caused a more considerable change in the level of CBCT-PAI score compared to other groups, thereby indicating a faster rate of bone regeneration.
