    Application benefits of Microdentistry in Endodontics

    In the past root canal treatment was performed predominantly by feel. Visualization tools such as OPMI® from ZEISS allow you to view details and fine structures that are otherwise difficult to see with the naked eyes. Treatments can be performed with far greater precision and predictability than ever before – at any step of the endodontic workflow:

    1 Canal location

    Locate difficult-to-see anatomy such as calcified and accessory canals. 

    2 Cleaning & obturation

    Controll cleaning and obturation of root canals in all dimensions.

    3 Examination of external tooth surface

    Identify cracks, root fractures and external root resorptions.

    4 Preservation of tooth structure

    Remove tooth tissue during preparation and refinement of the access cavity strategically.

  • Case Reports

    Canal location & cleaning

    One of the greatest challenges in endodontics is locating canals, especially calcified canals. Canals sclerose from coronal to apical and several millimetres of sclerotic dentine may have to be removed before the canal is found. ZEISS OPMI tremendously facilitates this important part of endodontic treatment. Use medium to high magnification and maximum illumination when searching for small canals.

    Endodontic Apicectomy

    Thanks to the improved visualization provided by OPMI along with microsurgical instruments, this procedure can be performed much more conservatively. For instance, the amount of apical bone removal/osteotomy size does not need to be large when using OPMI. Hence, the procedure could be considered as minimally invasive.

  • Hear what the experts say

    Prof. Dr. José Aranguren Cangas, Madrid, Spain

    "The root canal anatomy of teeth can be very variable and missed canals are a major cause of failure in root canal treatment. The OPMI tremendously facilitates this important part of endodontic treatment. It plays a vital role in helping to identify accessory canals at whatever level they may be."

    Dr. Manor Haas, Toronto, Canada

    "Thanks to the improved visualization provided by the OPMI along with microsurgical instruments, endodontic root-end surgery can be performed much more conservatively. The procedure could be considered minimally invasive."

    Dr. Tony Druttman, London, UK

    "Endodontic re-treatment is considered to be one of the most challenging procedures in endodontics. In these situations the OPMI is essential."
