Objectives: The aim of the present study was to determine if the Key can be easily used to extract remaining roots, and to assess the clinical outcome.
Study design: Five patients with remaining roots not suitable for forceps extraction were enrolled in this study, and had their remaining roots extracted using a novel atraumatic extraction system “The Key". Patients were evaluated clinically one week post-operatively.
Results: All the roots were successfully extracted, with average time 25 minutes. No patient complained from excessive intra-operative or post-operative pain, swelling or bleeding. All sockets evaluated one week post-operative showed uneventful soft tissue healing.
Conclusions: The Key may be successfully used for atraumatic extraction of remaining roots. Further studies are recommended with more number of cases, different surgeons, and comparison with other techniques.
