Bite force is an indicator of proper functioning of anatomical structures composing the masticatory system. Interest in the study of this force began more than 300 years ago, when Borelli first decided to obtain an evaluation of masticatory system using a device called Gnathodynamometer. Historically, G.V. Black built the first intraoral devices to measure bite force and they consisted of a lever, a spring and a manometer, or splints places over the teeth with a steel stud impinges. Different devices are now available to measure the bite force; they allow to analyze and prevent dysfunctions of masticatory system. The purpose of this study is to review new devices providing some important indications for clinicians.
