Aim: The aim of this study was to investigate sensitization (primarily central sensitization) after orofacial trauma using quantitative sensory testing (QST). Methods: A total of 32 healthy men (16 patients and 16 age-matched control subjects) underwent a battery of quantitative tests adapted to the trigeminal area at baseline and 2, 7, and 30 days following surgical removal of a lower impacted third molar. Results: Central sensitization for at least one week was indicated by significantly increased pain intensity evoked by intraoral repetitive pinprick and electrical stimulation (p < 0.05) including facilitation of temporal summation mechanisms (p < 0.05), extraoral repetitive electrical stimulation (p < 0.001), significantly more frequent aftersensation in patients (p < 0.001), extraoral hyperalgesia due to single pinprick stimulation (p < 0.05) and larger pain areas due to intranasal stimulation (p < 0.001). Peripheral sensitization was indicated by intraoral hyperalgesia due to single pinprick (p < 0.05). Conclusion: We found clear signs of sensitization of the trigeminal nociceptive system for at least one week after the surgery. Our results indicate that even a minor orofacial surgical procedure may be sufficient to evoke signs of both central and peripheral sensitization, which may play a role in the transition from acute to chronic pain in susceptible individuals.
