Tips for successful file progression indication
Implausible, rapidly changing indications from
Propex IQ
®
Apex Locator may have
various causes. Should you experience either situation, please review the below checklist
to identify possible causes and take appropriate actions.
Issue
Solution
Excess liquid in the pulp chamber or root canal
(i.e. rinsing solution, blood or saliva) creating
wrong conductive path and incorrect length
determination.
Dry the access cavity with a cotton pellet / air-
blower.
Wait until any bleeding has stopped.
Gingival proliferation can lead to direct contact
with the endodontic file causing a short circuit
and incorrect length determination.
Isolate the access cavity by:
•
Adequate preparation filling;
•
Placing a dental dam;
•
Electro-cauterizing.
The endodontic file contacting metallic dental
restorations (crown, intracanal, amalgam
filling) may cause a short circuit and incorrect
length determination.
Carefully enlarge the access cavity and isolate
with flow composite.
Widen carefully the opening at the top of the
crown.
No rubber dam and or
X-Smart IQ
®
Handpiece Sleeve is used. This may cause a
distortion of the electrical signal for the
reading.
Use a rubber dam and the
X-Smart IQ
®
Handpiece Sleeve.
