The objective of this study was to determine whether patients with phantom tooth symptoms have an altered sensory perception as compared to pain-free subjects. Ten patients (mean age 56, range 32-71, nine females) were diagnosed as suffering from "phantom tooth" according to a specifically designed phantom tooth questionnaire including components of the McGill Pain Questionnaire. An SCL-90 form was completed and assessment of sensory perception was carried out by determination of the threshold level for light touch sensation, two-point discrimination, and thermal sensation in a case-control design. Results. Of all the observed questionnaires, 5.7% seemed to deal with phantom tooth, with a female preponderance (ratio 9:1). Complaints were predominantly reported in the upper jaw (ratio 8:2) with the majority in the molar region (ratio 5:3). Phantom tooth subjects showed significantly lower threshold levels for light touch sensation, most markedly on the affected side. The average psychoneurotic profile showed a tendency towards higher scores for the phantom tooth subjects. Conclusion. The phantom tooth phenomenon may show a number of features which might aid differential diagnosis. To verify influences such as upper molar predominance and increased light touch sensation, another study should be performed on a larger patient sample.
