ENDODONTIC SURGICAL TREATMENT: LATERAL WINDOW APPROACH AND USE PRF. CASE REPORT

Abstract

Abstract Endodontic treatment needs a complete root canal disinfection and perfect sealing for a good conservative prognostic. Those treatments are performed also to build new crown when tooth is destroyed. This prosthetic construction is mandatory to insure the good mechanical prognosis, and to restore a complete function. But sometimes, those treatments fail. Due to the lack of disinfection for example, a new endodontic cleaning should be done. We need to retreat, and when the root access is not possible by an orthograde way (large intracanal post, perfect coronal restauration to preserve for example) a surgical approach is necessary. One key point of those treatments is also the retro preparation and retro filling of the apical part of the roots. Removing the inflammatory lesion is not sufficient, the origins of the abscess are all the intra canal bacteria, they could not be reached by the immune system of the host (immune cells are into the blood, and no more blood circulation could occur in an endodontically treated tooth. Same for all antibiotics). This case shows a new and original way to access the apical lesion, and how a blood concentration and Platelet Rich Fibrin membrane could be used to seal the bone window. The benefits of such technic are numerous, less pain, bone preservation, rapid healing, controlled bleeding of the area and improve the success rate.
