Abstract

Abstract Favorable outcomes have been reported with periodontal regeneration therapies using dental lasers for blood clot formation. Herein, we presented the clinical and radiographic outcomes of carbon dioxide laser-assisted bone regenerative therapy (LBRT) in periodontology. A 60-year-old man presented with mobility in teeth 43 and 44. Accordingly, the extraction of tooth 44 and periodontal regeneration using carbon dioxide-LBRT around tooth 43 were planned. After thorough debridement, enamel matrix derivative and carbonated apatite (CA) were applied to the root surface and bone defects, respectively. Thereafter, the filled blood-mixed CA was irradiated using a carbon dioxide laser to accelerate blood clot formation for stabilizing the bone graft. At the 13-month follow-up, significant improvements in clinical parameters were observed, indicating substantial bone regeneration. In this patient, the excellent clinical and radiographic healing demonstrated the efficacy of carbon dioxide-LBRT for periodontal regeneration. Blood clot formation using a carbon dioxide laser may lead to favorable outcomes.
