    Clearing solution
    Fixing solution
    Dehydrating solution

    THE MICROSEAL TECHNIQUE
    To utilize the advantages of a more fluid gutta-percha
    and reducing the risk of overfilling, an evolution of
    the multi phase technique has been proposed, which
    maintains unaltered the advantages of this obturation
    method, but in which the vertical control has been improved
    by the use of a master cone, which acts as an
    apical “cork” and which is positioned and condensed
    inside the canal before the introduction of the thermo-
    plasticized gutta-percha. This method is called the
    “microseal technique”.
    This technique utilizes cones of gutta-percha and
    pre -plasticised gutta-percha, both made with new generation
    high plasticity gutta-percha, as well as spreaders
    and thermo-mechanical condensers in NiTi capable
    of working in all the canal pathways. The presence
    of a master cone which engages the apex and whose
    physico-chemical characteristics allow integration
    with pre-heated gutta-percha enables a complete, but
    controlled filling of the endodontic space.
