Unsuitable situation of root canals for Electric Measurement

Cannot obtain precise measurements if the root canal conditions as below

Root canal with a large apical

foramen

The root canal cannot be accurately measured because of the lesion or incomplete development of the apical foramen. The results may show that the length measured is shorter than the

actual one.

Clean

Root canal blood overflow from the

opening

If blood spills from the root opening and contacts the gums, it will cause leakage of electricity, which cannot be accurately measured. Wait for the bleeding to stop completely. Clean the root canal and the opening, completely empty the root

canal blood, and then measure it.

The root canal uses a chemical

solution to flow out from the opening

If a chemical solution flows out of the root canal, it is impossible to get an

accurate measurement.

It is important to remove the overflow

Page 42 / 59

from the opening.

Build-up (e.g. cement)

Broken crown

If the crown is broken, a segment of the gingival tissue enters the lumen, and the contact between the gingival tissue and the root file causes electrical leakage, which cannot be accurately measured. In this case, the appropriate material should be used to isolate the gingival

tissue.

Branch

Crack

The crack tooth Leakage through

branch of the root canal

Broken teeth can cause electrical leakage and cannot be accurately

measured. Branch tubes can also cause leakage.

Page 43 / 59

Gutta-percha

Retreatment canal which was filled

with gutta-percha

The gutta-percha must be completely removed to eliminate its insulation, then pass a small file all the way through the apical foramen and then put a little saline in the canal, but do not let it overflow the

canal opening.

Crown

Crown or metal prosthesis that

touches gingival tissue

Accurate measurement cannot be obtained if the file touches a mental prosthesis that is touching gingival tissue. In this case, widen the opening at the top of the crown so that the file will not touch the mental prosthesis before

taking a measurement.

Debris

Pulp

Cutting debris on tooth Pulp inside

canal

Remove all cutting debris on the tooth.

Remove all the pulp inside the canal. Otherwise an accurate measurement

cannot be obtained.

Caries touches gums

Caries touching the gums

In this case, electrical leakage through the caries infected area to the gums are impossible to obtain an accurate

measurement.

Page 44 / 59

Blocked

Blocked canal

The meter will not run if the canal is blocked. Opening the canal all the way

to the apical construction to measure it.

Too dry

Extremely dry canal

If the canal is extremely dry, the meter may not work until it is quite close to the apex. In this case, try to moisten

the canal with oxydol or saline.

Difference measuring result between Apex locator reading and Radiography

Sometimes the reading of the apex locator reading does not correspond to the Xray image. this does not mean inaccurate of apex locator or X-ray, depending on the angle of the X-ray beam, the root tip may not be displayed correctly. The

position of the root tip seems to differ from its true position.

X-ray tube

X-ray photo

The X-ray photo shows that the actual apex of the root canal is not the same as the anatomic end. In fact, the apical foramen is located at the coronal end. in this case, X-ray may indicate that the file needle has not reached the apical foramen, even if it has actually reached

the apical foramen.
