What to do if the Canal Length Indicator doesn't move on my Morita DENTA PORT ZX Dental equipment?
- B
  Brian HarveyAug 9, 2025
  The canal length indicator may not move at all, or only when the file tip is close to the apical foramen if the canal is blocked, the apical foramen is very large and open, or the canal is extremely dry. To resolve this, open the passage all the way through the apical constriction first and then take the measurement. If the apical foramen is large or wide open and not completely formed, the canal length indicator bar will suddenly jump when the file tip gets close to the apex. Moisten the canal with oxydol or a saline solution.

Why is the Canal Length Indicator unstable on my Morita DENTA PORT ZX Dental equipment?

  Paula ZavalaAug 14, 2025
  The Canal Length Indicator might be unstable if the contrary electrode isn't making good contact with the oral mucosa, or if the file holder is dirty. Ensure the contrary electrode makes good contact with the oral mucosa. Clean the file holder with Ethanol for Disinfection (Ethanol 70 vol% to 80 vol%).
