Inadequate irrigation protocol (volume/activation/contact time)
What it is
Doing "minimal" irrigation (small volumes, few replenishments), using NaOCl without proper exchange/contact time, or skipping activation/agitation, so irrigant doesn't penetrate fins/isthmuses and doesn't contact walls long enough to work — resulting in suboptimal chemomechanical disinfection.
Why it happens
• Treating irrigation as a quick rinse instead of a core disinfection step • Small apical prep/taper + coronal interferences → irrigant can't reach apical third effectively • Fear of extrusion → clinician uses too little irrigant (instead of using safer delivery methods like side-vented needle, gentle flow, negative pressure when indicated) • No activation device or not using simple activation methods (manual dynamic agitation / ultrasonic / sonic)
