of the root canal which is filled with 

blood, liquid, it will display “OVER” 

immediately. In this case, push the needle 

to the apical root canal, then the display 

will be normal, you can measure the 

length of the root canal correctly.

If there is liquid, scrap on the tooth 

surface?

Clean the tooth surface.

If the endo needle contact the gums?

It will display “OVER” if the endo needle 

contact the gums.

Display not steady while 

measuring: the measurement 

result is rather longer or 

shorter; numerical display 

irregular. 

If there is still pulp in the root canal?

If there is much pulp left in the root canal, 

the root canal length can’t be measured 

correctly.

If the needle touched the metal repaired 

material?

Once the needle touched the metal 

repaired material, current measurement 

from the gums to the periodontal tissue 

loss, the screen will display “OVER”.

If the adjacent surface has caries?

Current measurement flow from caries of 

the adjacent surface to gums, then the root 

canal length can’t be measured correctly.
