- Chair-side intraoral somatosensory examination in patients with atypical odontalgia and healthy subjects L Baad-Hansen, M Pigg, S Elmasry Ivanovic, H Faris, T List, M Drangsholt, P Svensson Aim of investigation: In patients with persistent orofacial pain, assessment of somatosensory function is recommended. A chair-side qualitative examination with good reliability revealing signs of hyper-/hyposensitivity to touch, cold and painful pinprick stimulation may be performed. The aim of this multicenter study was to compare three qualitative measures of intraoral somatosensory function between patients with atypical odontalgia (AO) and healthy subjects. Methods: 31 AO patients (6 male, 25 female; mean age: 54±13) and 47 healthy age- and sex-matched controls (15 male, 32 female: mean age: 47±12) were recruited from Malmö University (Sweden), University of Washington (USA) and Aarhus University (Denmark). In AO patients, sensitivity to touch, cold, and pinprick stimuli was evaluated on the buccal gingiva adjacent to the painful site and the corresponding contralateral ‘mirror-image’ gingival site. In healthy subjects, tests were performed bilaterally on the buccal gingiva adjacent to the first maxillary premolars. Patients were asked to report hyper-, hypo-, or normo-sensitivity/- algesia to touch, cold and painful stimuli on the painful site compared with the contralateral site; healthy subjects were asked to compare sensitivity between sides. Χ2-tests were used to analyze differences in frequency of hyper-, hyposensitivity or normosensitivity between groups. Results: The frequency of subjectively reported normosensitivity to all stimulus modalities were significantly lower in patients (23-58%) than in healthy subjects (68-91%), P<0.001. Frequency of hypersensitivity to all modalities were significantly higher in patients (29-61%) than in controls (9-17%), P<0.015, whereas reports of hyposensitivity were similar between groups (2-16%), P>0.054. Conclusion: A quick and simple chair-side evaluation of intraoral somatosensory function can detect intraoral sensory disturbances in AO patients, mainly in the form of hyper-sensitivity. These tests may be useful in the initial screening of patients with persistent orofacial pain.

- AIMS: To assess intraoral inter- and intraexaminer reliability of three qualitative measures of intraoral somatosensory function and to compare these measures between patients with atypical odontalgia (AO) and healthy controls. METHODS: Thirty-one AO patients and 47 healthy controls participated. Inter- and intraexaminer reliability was tested on a subgroup of 46 subjects (25 AO; 21 healthy). Sensitivity to touch, cold, and pinprick stimuli was evaluated on the painful gingival site and the corresponding contralateral site in AO patients, and bilaterally on the gingiva of the first maxillary premolars in controls. Patients were asked to report hypersensitivity, hyposensitivity, or normal sensitivity to stimuli on the painful site compared with the nonpainful site. Kappa values were calculated, and chi-square and Fisher's exact tests were used to compare frequencies between groups. RESULTS: Kappa values ranged between 0.63 and 0.75. The frequency of hypersensitivity to either modality was significantly higher in patients (29% to 61%) than in controls (9% to 17%) (P < .015), whereas reports of hyposensitivity were similar between groups (2% to 16%) (P > .057). Only 3.2% of the AO patients had no reports of abnormal sensitivity on any of the tests, compared with 59.6% of the healthy subjects (P < .001). CONCLUSION: Intraoral qualitative somatosensory testing can detect intraoral sensory disturbances in AO patients, and the reliability is sufficient for initial screening of orofacial somatosensory function.

- Intraoral somatosensory sensitivity in patients with atypical odontalgia (AO) has not been investigated systematically according to the most recent guidelines. The aims of this study were to examine intraoral somatosensory disturbances in AO patients using healthy subjects as reference, and to evaluate the percent agreement between intraoral quantitative sensory testing (QST) and qualitative sensory testing (QualST). Forty-seven AO patients and 69 healthy control subjects were included at Universities of Washington, Malmö, and Aarhus. In AO patients, intraoral somatosensory testing was performed on the painful site, the corresponding contralateral site, and at thenar. In healthy subjects, intraoral somatosensory testing was performed bilaterally on the upper premolar gingiva and at thenar. Thirteen QST and 3 QualST parameters were evaluated at each site, z-scores were computed for AO patients based on the healthy reference material, and LossGain scores were created. Compared with control subjects, 87.3% of AO patients had QST abnormalities. The most frequent somatosensory abnormalities in AO patients were somatosensory gain with regard to painful mechanical and cold stimuli and somatosensory loss with regard to cold detection and mechanical detection. The most frequent LossGain code was L0G2 (no somatosensory loss with gain of mechanical somatosensory function) (31.9% of AO patients). Percent agreement between corresponding QST and QualST measures of thermal and mechanical sensitivity ranged between 55.6% and 70.4% in AO patients and between 71.1% and 92.1% in control subjects. In conclusion, intraoral somatosensory abnormalities were commonly detected in AO patients, and agreement between quantitative and qualitative sensory testing was good to excellent.
