Reviewing Intercanal Medicaments
R. Scott Gatewood, DMD
After hearing this podcast, the listener should:
- Understand the advantages and disadvantages of several intercanal medicaments
- Be able to name at least 3 intercanal medicaments
Advances in technology have improved
the use and quality of tooth-canal instrumentation. Available irrigants (ie, NaOCl,
chlorhexidine, EDTA, and MTAD) provide antibacterial tissue solvent and
smear-removing capabilities that aid in cleaning the root canal system of
tissue remnants, bacteria, bacterial products, and dentinal debris. In spite of
this, root canals with nonvital pulp often retain viable bacteria after
instrumentation. The complexity of the root canal system and the inability of
instruments or irrigants to eradicate all bacteria contribute to this result. To
decrease the bacterial count of a tooth canal in patients whose treatment plans
include a series of appointments, a wide range of materials have been sealed in
the tooth between appointments as intercanal medicaments.
