Twinlight Endo Treatment - How Er:YAG Completes our Nd:YAG Endoprotocol (Summary)
Traditional protocols involve, at root level, the cleaning of the main root canal using standard mechanical procedures, combined with antibacterial rinsings. However, there are two major disadvantages of standard chemo-mechanical preparations. First, the bactericidal effect of the rinsing solutions is limited to the root canal and its immediate neighbourhood systems to a max depth of 100μm, due to the very complex anatomy of the dentinal tubules and the high surface tension of the liquids. But bacteria can penetrate over 1000μm from the canal lumen, remaining protected in deeper layers of dentin. The second important disadvantage is that a complete mechanical preparation of the complex side canal system, as well as the complete removal of the smear layer, are almost impossible with classical protocols.
