Skipping rubber dam isolation
AreaEndodontics
What it is
Starting access, instrumentation, irrigation, or obturation without isolating the tooth with a rubber dam (or placing it late, after contamination has already occurred).
Why it happens
• "Quick emergency" mindset (pain visit, time pressure) • Clamp/dam placement feels difficult (partially erupted teeth, broken-down crowns, limited mouth opening) • Patient discomfort/anxiety or gag reflex • Poor training/habit, or assuming cotton rolls/suction is "good enough" • Underestimating medico-legal and safety risk

More clinical mistakes
Wrong working length (no apex locator / poor WL confirmation)Missing an extra canal (e.g., MB2)Inadequate access cavity (missed anatomy / straight-line access not achieved)Ledge formation during negotiation/shapingCanal transportation / zipping in curved canalsApical over-instrumentation (loss of apical constriction)Separated instrument not recognized early / poor management planStrip perforation in danger zonesFurcation perforation during accessSodium hypochlorite accident / irrigant extrusionInadequate irrigation protocol (volume/activation/contact time)Poor inter-appointment temporization (coronal leakage)
