OBJECTIVES: The aim of this study was to compare the mastication electromyographic indexes of capsules used for the masticatory efficiency evaluation "ME-mastig" and of materials of different textures (gum, raisins, and peanuts). METHODS: Thirty young, healthy, adult subjects, with an average age of 23.46 years old, with no symptoms of temporomandibular dysfunction (TMD), confirmed by the clinical exam, RDC/TMD, and the static test of electromyography (EMG) were chosen. Afterward, dynamic tests were performed (bilateral mastication of the compounds) to determine number of chewing cycles (CYCLES); masticatory frequency (FREQ); SMI (symmetrical masticatory index - corresponding to the value of neuromuscular coordination during mastication); and IMPACT (corresponding to impact - total electromyographic activity performed by the system during chewing). RESULTS: Cycle and frequency were similar. Regarding SMI and IMPACT, the raisin, the capsule, and the peanut were similar between each other, and different from the gum. CONCLUSIONS: Masticatory capsules and the natural foods with different textures had similar results regarding EMG indexes.
