Summary
Quantitative Sensory Testing (QST) effectively assesses nerve injury after dental implants. This method provides objective data for diagnosing altered sensation, unlike Somatosensory Evoked Potentials (SEP) or thermography.
Area of Science:
- Neurology
- Dental Implantology
- Diagnostic Methods
Background:
- Altered sensation is a potential complication of dental implant treatment.
- Objective diagnostic tools are needed to evaluate nerve injury in these cases.
Purpose of the Study:
- To evaluate Somatosensory Evoked Potentials (SEP), Quantitative Sensory Testing (QST), and thermography as diagnostic methods for nerve injury.
- To determine the efficacy of these methods in patients with altered sensation following dental implant procedures.
Main Methods:
- A cohort of 17 patients with altered sensation post-dental implant treatment was studied.
- Patients underwent assessment using SEP, QST, and thermography approximately 15.2 months after symptom onset.
Main Results:
- Quantitative Sensory Testing (QST) revealed significantly higher current perception thresholds on the affected side.
- Somatosensory Evoked Potentials (SEP) showed delayed N20 latency, but the difference was not statistically significant.
- Thermography indicated minimal temperature differences without statistical significance.
Conclusions:
- Quantitative Sensory Testing (QST) is a valuable and objective method for assessing nerve injury.
- QST demonstrates superior diagnostic utility compared to SEP and thermography for evaluating altered sensation after dental implant treatment.
