RESUMEN

There is an increased chance of further periodontal deterioration due to severe intrabony defect. There are s different patho physiologies for perio-endo lesions, ranging from quite basic to rather complicated but to make the right diagnosis, one must be aware of various illness processes also a careful history taking, examination, and the application of specialized tests can help achieve this. Each form of endodontic-periodontal illness has a different prognosis and course of therapy and all kinds of endo-perio lesions require endodontic and periodontal treatments are necessary for primary periodontal disease with subsequent endodontic involvement and real mixed endodontic-periodontal disorders. The severity of the periodontal disease and how well the patient responds to therapy will determine how these situations turn out. Because autologous platelet concentrates are enriched with growth factors, such as concentrated growth factor (CGF), they may enhance surgical outcomes. CGF is inserted into the appropriate intrabony defect following traditional flap debridement. Following flap surgery, the tooth in question had a root canal operation. Volumetric analysis was performed on both groups before to surgery and nine months after the procedure. It has been discovered that the defect area has a much larger bone volume due to the high levels of CGF, a regenerative and reconstructive growth factor that promotes early and high bone fill.
