Speaker Profile

Dr Spyros Floratos DMD

 

Dr Floratos received his DMD from the University of Thessaloniki School of Dental Medicine in Greece in 2001 and joined the Greek Navy as an Active Duty Dental Officer. In 2009 he graduated from the full-time Residency program in Endodontics and Microsurgery offered at the University of Pennsylvania School of Dental Medicine in USA.  He received the Louis Grossman Award for ‘Outstanding Proficiency in the Graduate Program’ offered upon graduation from the Endodontic Program. Since 2009, he holds an Adjunct Assistant Professor appointment at the Endodontic Department of University of Pennsylvania.  He was the Director of the Endodontic Department of the Athens Naval Hospital in Greece for 10 years and retired in 2019 as a Commander Endodontist of the Greek Navy.  He is the primary author of 3 chapters at the “Microsurgery in Endodontics”  Textbook by Kim & Kratchman published in 2018, as well as one chapter in ‘Endodontic-Periodontal Lesions’ by Tsesis & Rosen published in 2019.  His clinical cases have been published at the ‘ Pathways of the Pulp’ Textbook and ‘Ingle’s Endodontics’ Textbook.  He has presented in endodontic meetings in USA and Europe and has published in national and international endodontic journals.

Learning content:

In the era of ‘white’ and ‘pink’ esthetics, the primary objective of preserving the natural dentition is no longer acceptable if we do not consider esthetic consequences.

Μodern endodontic microsurgery aims to predictably eliminate periapical pathosis in a minimally invasive way both for the hard and soft tissues. 

However, when we do an endodontic surgery we may solve the endodontic problem, but we may create an aesthetic problem for the patient. 

Knowledge of essential anatomical landmarks, blood vasculature and wound healing are mandatory in order to obtain an excellent soft tissue healing outcome postsurgically. This presentation will address incisions and flap designs for all tooth locations as well as criteria for proper flap design selection. At the same time, atraumatic flap manipulation and suturing techniques under the microscope can enhance the clinician’s surgical skills and will be thoroughly discussed throughout this presentation.

Title: Navigating the Endodontic-Periodontal Interface – Is Extraction the Ultimate treatment?

Endodontic-Periodontal lesions arise from pathological communication between the dental pulp and supporting periodontium, involving the migration of microorganisms and inflammatory mediators. While various classifications exist, Simon et al. (1972) provided the widely used system based on the primary source of infection. In 2018, Herrera et al. introduced a new classification focusing on current disease status and prognosis.

Despite the challenges and poor prognosis associated with EP-affected teeth, a multidisciplinary approach involving dentists, endodontists, and periodontists is crucial for effective care planning and improved treatment outcomes.

​

Endodontic Microsurgery can be the only treatment option to remove a persistent apical lesion and address the endodontic disease, especially if a nonsurgical retreatment attempt might compromise the prognosis of the tooth. Missed apical anatomy, resorptive areas along the root, complete canal blockage, multiple iatrogenic mishaps on a single tooth and anatomical irregularities are some of the conditions that can be efficiently managed with modern microsurgical protocols.  

    At the same time, cases with persistent infections caused by severe endodontic-periodontal pathology or a failed previous surgery can turn into success if a strict microsurgical protocol is applied.  The reasons for the failure of initial endodontic surgery have not been clearly highlighted in literature. Several factors, such as the absence or incorrect placement of a root-end filling, missed anatomy, off axis root end preparation have been associated with a surgery failure.  The evaluation of failed surgical cases by resurgery enables direct inspection of the previous surgical site, thereby providing further insight into the cause for failure.  

     A correct diagnosis based on the CBCT and a careful case selection to implement microsurgery can lead to a predictable healing for lesions of endodontic origin.

     This comprehensive lecture aims to highlight the clinical approach for challenging cases with previous failed endodontic intervention and persistent periradicular pathology. A rationale for the management of this kind of cases will be thoroughly discussed.

​

Aims and Objectives:

• Describe indications of different flap designs in endodontic surgery.

• Familiarize with atraumatic manipulation, proper predictable suturing of the mucosal tissues under the microscope.

• Expand knowledge in muco-gingival surgical procedures.

• understand the reasons for failure and clinical findings during surgery and resurgery  in complex endodontic cases

• provide an answer to clinical dilemmas and develop a strategy for management of surgical endodontic treatment in challenging cases

• comprehend the rationale for proper case selection ιn the surgical treatment of lesions of endodontic origin

• efficiently interpret the clinical, as well as CBCT radiographic findings in a surgery failure case

• describe the indications for performing an endodontic resurgery procedure
