  1. Composite Root End Fillings

  2. Bond strength measurements are probably not important Tendency to develop gaps is probably very important Important and Non Important

  3. Cytotoxicity • Rakich, D. R., J. C. Wataha, et al. (1998). "Effects of dentin bonding agents on macrophage mitochondrial activity." J Endod24(8): 528-33. • Peltola, M., T. Salo, et al. (1992). "Toxic effects of various retrograde root filling materials on gingival fibroblasts and rat sarcoma cells." Endod Dent Traumatol8(3): 120-4. • Osorio, R. M., A. Hefti, et al. (1998). "Cytotoxicity of endodontic materials." J Endod24(2): 91-6.

  4. Biocompatibility • Ozbas, H., M. Yaltirik, et al. (2003). "Reactions of connective tissue to compomers, composite and amalgam root-end filling materials." Int Endod J36(4): 281-7. Valux Plus composite (3M), Dyract and F2000 compomers and Oralloy amalgam were equally biocompatible.

  5. Biocompatibility • Zhu, Q., R. Haglund, et al. (2000). "Adhesion of human osteoblasts on root-end filling materials." J Endod26(7): 404-6. Adhesion of osteoblasts to composite same as MTA.

  6. Microleakage • Fogel, H. M. and M. D. Peikoff (2001). "Microleakage of root-end filling materials." J Endod27(7): 456-8. There was no significant difference of microleakage between a dentin-bonded resin, Super-EBA, and mineral trioxide aggregate.

  7. Retroplast • Retroplast is a Bis-Gma (Bisphenol A-Glycidyl Methacrylate) composite.

  8. Retroplast Jensen SS, Nattestad A, Egdø P, Sewerin I, Munksgaard EC, Schou S: A prospective, randomized, comparative clinical study of resin composite and glass ionomer cement for retrograde root filling. Clin Oral Invest 2002;6:236-243 Seems to hold up over time much better than GI’s

  9. Ultrablend • Ultrablend is a Urethane dimethacrylate Bis-Acrylic Resin (UDMA) Composite Resin combined with Calcium Hydroxide.

  10. Hemostasis with Viscostat • With Dento Infusor and rubbing

  11. Extraneous coagulum is removed • So that almost all the coagulum is within just the blood vessel orifices; not large clumps throughout the crypt.

  12. Make apical preparation • Using Carr Retrotips

  13. Apical Preparations

  14. Retroplast • Rud J, Munksgaard EC, Andreasen JO, Rud V, Asmussen E: Retrograde root filling with composite and a dentin bonding agent I. Endod Dent Traumatol 1991;7:118-125They used monkeys in Copenhagen and showed that the histologic response to a retrograde root filling procedure using composite and a dentin bonding agent (Gluma) was favorable.

  15. Ultra-Etch • With a Nano tip (either 30 or 31 gauge). • Deliver to the preparation slightly beyond preparation margin. * • This also prevents finishing abrasives from contaminating the crypt. • Etch for 15-20 seconds. * (This assures flash of resin is bonded to the root as it is first choice to not disturb the finished restoration with mechanical finishing.)

  16. Surgi Tip • Use Luer Vacuum Adapter with SurgiTip at first only to vacuum the etch from the preparation. Then wash out the preparation and end of root. The TriAway or Stopko with a Black Mini tip works well for this.

  17. PQ1 or PQ Clear • With a Nano tip 31 gauge (orange). • Deliver a moderately thick layer of the adhesive to the preparation and slightly beyond the margin.

  18. Suck excess resin out • Including from the depth of the preparation. • Luer Vacum Adapter wit surgi tip • Hold SurgiTip vacuum near root end for 15-20 seconds so to facilitate drying of solvent from bonding resin. • Careful with light (orange filter in scope)

  19. Or blow Gently with Stropko

  20. Cure the bond resin • 20 seconds • With EndoGuide attached to UltraLume II

  21. Ultra-Blend with 30 gauge Nano • totally coat the inside of the preparation • just beyond the margin • Light cure using EndoGuide for 10 seconds.

  22. Add increments of Ultra-Blend • One or Two as needed. • Polymerize each layer 10 seconds.

  23. Scrape to remove any residual coagulum • Small quantities within capillaries are not a problem. • Do scrape to initiate some moderate bleeding however • Suture as usual.

  24. DeOx • . With a Nano tip on the DeOx syringe • coat the outer surface of Ultra-Blend with a moderately thick layer of DeOx. • Set the EndoGuide tip end into the DeOx and polymerize for 10-20 more seconds.
