The Emotion Spectrum Analysis Method uses an electroencephalograph to measure scalp potential at ten locations, in order to quantify mental stress, joy, depression and relaxation. The aim of this study was to compare these emotions in four individuals only, with and without an experimental occlusal interference. The occlusal interference (100 μm) was created by luting temporarily a modified casting onto a first mandibular molar tooth. The subjects were asked to chew gum during the experimental periods. When there was an occlusal interference, there were no consistent findings with respect to stress, joy, depression or relaxation. However, in three subjects, stress increased with an associated decrease in relaxation.
