Poor inter-appointment temporization (coronal leakage)
What it is
Placing a temporary restoration between visits that leaks, dislodges, fractures, is too thin, has voids, or is left too long — allowing saliva/bacteria to re-enter the access cavity and recontaminate the canal system (coronal leakage).
Why it happens
• Temporary too thin or poorly condensed → gaps/voids • Too much cotton pellet (or poorly positioned) → lifts/dislodges the temp • Occlusion not checked → high spot fractures the temporary • Using a temporary as if it were "long-term," delaying definitive restoration • Poor margins due to caries/defective restoration not addressed before RCT AAE specifically lists common failures of temporization as: inadequate thickness, improper placement, and failure to evaluate occlusion.
