Comparative Study
Reliability of a new technique for intraoral mapping of somatosensory sensitivity.
Diagnosis of intraoral pain conditions may be facilitated by assessment of somatosensory sensitivity not only at a single test site but also at multiple test sites, that is, intraoral somatosensory mapping. No standardized mapping techniques are currently available. The aim of this study was to evaluate: (1) spatial variations in somatosensory sensitivity; (2) the reliability of a new technique for mapping of intraoral somatosensory sensitivity. ⋯ Generally, the anterior and apical regions were more sensitive than posterior and cervical regions. Intraclass correlation coefficients for between session reliability ranged between 0.76 and 0.87 for NRS scores and PiPT measures. In conclusion, good test-retest reliability of intraoral somatosensory mapping was found with the help of a new template, which can be used for further studies of intraoral pain mechanisms.
