Sealbio: a novel non-obturation regenerative technique of endodontic treatment

A novel non-obturation, regenerative technique “SealBio” of endodontic treatment involving regenerative potential of stem cells and signaling molecules, locally available in the peri-radicular region of teeth, wherein they are stimulated to induce healing and deposition of a natural barrier (seal) at the root apex comprising the steps of:

• —
• i) canal cleaning with special attention to the apical third of the canal
• ii) establishing apical patency with #10 reamer to prevent clogging of apical foramen with debris
• iii) irrigating canals thoroughly with NaOCI and confirming the apical patency with #10 size reamer and then gradually widened size #15
• iv) taking a fresh #15 size sterile reamer 2-3 mm past the apical foramen and gently rotating clock wise, giving 2-3 turns withdrawing reamer giving anti clock wise rotation
• vi) introducing a sub base of zinc oxide eugenol (Kalsogen) in the access cavity and condensing with a hand plugger in to the cervical ⅓rd of root canals
• vii) placing a base of Zn-phosphate cement and giving silver amalgam restoration after application of cavity varnish at the same sitting.
• viii) In cases with extensive crown destruction, a base of cavit, instead of Kalsogen is similarly packed into the pulp chamber and coronal ⅓ of root canals the excess is removed from the walls of cavity, dentinal walls are preconditioned with 10% poly acrylic acid for 10 seconds and the core is built with cermet cement and a full crown restoration is given.
