Trigeminal evoked potentials in humans

The diagnosis and management of nerve injury during endodontic treatment

“…However, the fundamental marker of a sensory malfunction is the patient's own subjective complaints (Yatsuhashi et al, 2003;Pogrel, 2007;Juodzbalys et al, 2011;Bennett et al, 1987;Bennett & Jannetta, 1980). Presently, there is no agreement as to the ideal techniques to assess nerve injury following endodontic treatment.…”

“…Objective sensory tests (Kim et al, 2015;Agbaje et al, 2015) are aimed to avoid a possible bias from the subjectivity of the clinical sensory testing (Rosen, 2014;Fagade & Wastell, 1990;Bennett et al, 1987;Bennett & Jannetta, 1980;Agbaje et al, 2015;Barker et al, 1987). "Trigeminal Evoked Potentials (TEP)" and "Quantitative sensory testing (QST)" (Kim et al, 2015) are examples of objective and non-invasive methods to measure peripheral neural function (Kim et al, 2015;Zhao et al, 2017), that may be used as an adjunct in the diagnostic process following trigeminal nerve injuries (Rosen, 2014;Fagade & Wastell, 1990;Bennett et al, 1987;Bennett & Jannetta, 1980;Barker et al, 1987).…”

“…These evaluation methods may require professional expertise that is beyond the dental practitioner's clinical capacity (Pogrel, 2007;Chaushu et al, 2002;Fagade & Wastell, 1990;Bennett et al, 1987;Bennett & Jannetta, 1980;Barker et al, 1987). However, the practitioner needs to be sensitive to the possibility of nerve injury following the endodontic treatment, and should recognize the possible risk factors and clinical manifestations (Pogrel, 2017;Rosen, 2014;Ghali & Epker, 1989).…”
