Abstract: An endodontic file measuring device includes a housing with an upper opening for receiving the file within a file channel in the housing. A movable base is disposed in the file channel and a plurality of sensors are disposed along the file channel. When a tip of the endodontic file is positioned on the movable base, the sensors can detect a presence of the file within the channel and measure a length of the file in the channel. A slider protrudes from the front wall of the housing and is connected to the base by a connecting rod. The slider can be manipulated by the user to lower or elevate the file within the base. A display on an outer surface of the housing displays the length of the file present in the file channel.
