Figure 1. Diagrammatic illustration of escape pain phenomenon (EPP) and neurovascular plexus (NVP) theory during the two section technique of third molar removal (inner figure: mesioangular mandibular third molar impaction). (a) Conduction block; (b) neurovascular/nerve plexus entering into the bony canal; (c) compression of the neurovascular bundle; (d) escape of pain away from conduction blockade through neurovascular/nerve plexus
