Objective: To report the clinical outcome of autogenous bone powder (ATB) combined with concentrated growth factor (CGF) in the treatment of bone defects after jaw cyst surgery. Method: Patients diagnosed with jaw cysts underwent routine surgical curettage of the cysts, followed by implantation of autogenous bone powder combined with concentrated growth factor

into the bone defect area. Bone formation was assessed using cone beam CT (CBCT) 6 months postoperatively. Results: Good bone formation was observed in the surgical area.Conclusion:Autogenous tooth bone powder combined with concentrated growth factors can be used as a filling material for bone defects after jaw cyst surgery and can be applied clinically.

Objective: To retrospectively analyze a case of uncontrollable bleeding after supragingival scaling that occurred in May 2023 at the People’s Hospital of Fengqing County, Yunnan Province. The prevention and management for uncontrollable bleeding caused by systemic factors after invasive oral procedures was discussed. Methods: Multidisciplinary consultation were conducted with the cardiology, pharmacy, and hematology-endocrinology departments. Local treatment included the application of levonordefrin tartrate and cold saline.Intravenous administration of vitamin K and tranexamic acid was also provided.Results: Hemostasis was achieved locally within 48 hours. The patient's vital signs stabilized, and follow-up laboratory examinations showed no significant abnormalities. Conclusion: A thorough inquiry into the patient's medical history is essential before performing invasive oral procedures. For patients on long-term anticoagulant therapy, particularly those using multiple anticoagulants, multidisciplinary consultations can effectively guide treatment and reduce the risk of postoperative bleeding.
