While generally, the term "root canal
treatment" is used to refer to cases 2 ~ 4 above, this
term originates from the fact the treatment mainly targets
the fine canals (i.e. root canals) that support the root
of the tooth as shown in Fig. 1.
A fine needle-like instrument and surgical
operating microscope are used to carefully remove
pulp tissue, bacteria and old filling material from the
root canal. As shown in the illustration, the root canal
structure is complex, making the removal of infectious substances
an extremely difficult procedure.
The provision of high-quality root
canal treatment using high-quality restorative materials
at stages 2 (Root Canal Treatment (Vital Teeth)) and 3 (Root
Canal Treatment (Necrotic Teeth)) almost completely eliminates
the likelihood of having to undergo stage 4 (Root Canal
Retreatment) and 5 (Endodontic Surgery) procedures.
