Title : Decompression of a radicular cyst associated with a root treated lateral incisor before commencement of apical surgery


This presentation will document the referral, assessment, planning, and procedure to reduce the size of a cyst associated with the patient’s root-filled upper left lateral incisor. Due to the nature of his presentation, immediate treatment with traditional surgical endodontics would have compromised not only the tooth in question but also the adjacent dentition as the radiolucency and evident bony destruction extended to teeth 21 and 23. Due to this added complexity, marsupialization was attempted to shrink the existing lesion and allow for bony infill as much as possible, before attempting an apicectomy to remove the cause of infection. I will outline a brief overview of the apical disease and cyst aetiology, the reasons why these lesions expand as they do, and differential diagnoses which should be considered at the assessment appointment. I will also establish what the patient needs to be aware of before they commit to marsupialization, and the medico-legal protocol for documenting this consent process (including photography). The advantages and disadvantages of this technique will be discussed, alongside alternative treatment options for the patient and the necessity to be critical with case selection when conducting treatment of this type. I will also briefly touch on the materials used and the rationale behind this, as well as the follow-up procedure, and what should be noted at review appointments including favorable and non-favorable outcomes for this treatment.

Audience Takes Away Notes:

  • This presentation will give the audience an opportunity to learn how marsupialization can be used for cases where immediate treatment with apicectomy could compromise the affected tooth and the adjacent dentition.
  • It will refresh member’s knowledge of oral disease and pathology, whilst linking it to the practical management of these conditions
  • It will critically analyze the procedure carried out and show regions that could be explored in the future


Dr Claire Dewshi graduated from King’s College London, England, in 2019 and continued to pursue further training years in secondary care following Foundation Training in South-West London. Having worked in a Maxillo-facial unit in Sussex and then a Restorative Dental Unit in Swansea, Claire has had the opportunity to see how head and neck cancer patients are treated surgically, and subsequently restored dentally under the care of a multidisciplinary team.
She has a passion for dental education and mentorship which has led her to becoming involved with dental charities and widening participation groups to improve access to dental schools.
