Abstract

Objectives - The late exteroceptive suppression period (ES2) of the masseter muscle is conventionally quantified by a combination of measures of duration, amplitude, or mean activity. The combination of measures makes it difficult to compare ES2s obtained from different set-ups,An unbiased method for quantitating ES2 is Introduced allowing ranking of ES2s. The introduced method is utilized to evaluate stimulus and recording conditions under which ES2 is maximal. Material and methods - Fifteen male volunteers participated in 3 experiments designed to determine the effect of level of teeth clenching, stimulus intensity, and perceived pain intensity on the ES2. Results - Coefficients of variance (1 h/l month) were: duration: 11%/43%, latency: 9%/12%, and magnitude of suppression: 11%/12%. A level of teeth clenching of 66% of maximal voluntary bite force, and a stimulus intensity below pain detection threshold was associated with maximal magnitude of suppression of ES2, Conclusion - The introduced method is reproducible and allows ranking and stimulus-response estimations of ES2. It is suggested that ES2 does not reflect activity along the nociceptive pathways in the trigeminal region.
