5. Dental Operation with Device (for reference)
5.1 Requirements
Warning:
This device should be operated by a qualified and licensed dental professional.
Read this manual before operation
•
A fully exposed access cavity to show the pulpal cabin.
•
An X-ray photo to show the whole length and root canal of the teeth.
• The endo file should not be too big nor too small to avoid cutting through the apical foramen.
•
Mark an anatomized symbol on the diseased tooth and memorize it on the case history.
This symbol should be marked on the health bridge or on the tooth filled integrated. The
position of the mark should be on the incisal edge of the anterior tooth or on the spire of the
molars. For those bridge that's broken obviously, this symbol should be on the tooth surface
supported by the dentin instead of on the suspended enamel.
• The acute inflammation surrounding the apex has been gone and the infected material has
been cleaned. It is also necessary to get rid of the pulp and necrosis tissue.
5.2 Cases not suited for normal measurement
Case 1
The size of the root is similar to the size of
apical foramen.
In this case, the measurement result of the
length of the root canal will be shorter than its
real length because of the hypoplasia of the root.
