The automatic detection of the movement of a point of the mandible can be a useful tool for the diagnosis of Temporo-Mandibular Disorders. Two detection techniques are presently used, based respectively on the measurement of a magnetic field and on the processing of image sequences. In the frame of an agreement between the Istituto di Scienza e Tecnologie dell'Informazione of the National Research Council of Italy and the Dipartimento di Medicina Traslazionale of the University of Eastern Piedmont "Amedeo Avogadro" regarding the development of innovative approach we studied a detection technique based on the measurements provided by an accelerometer. The paper reports the results obtained using a general purpose device, available at IEI, to detect accelerations in cyclic mechanical movements, similar to the mandibular ones.
