Abstract: A device for measuring the circumference of a tooth or other object, having a longitudinally extending handle with a first end, a second end, an exterior and a hollow interior. A rotatably mounted head portion is disposed at the first end of the handle, and has an aperture which connects the hollow interior to the exterior of the handle. The head portion is adjustable to locate the aperture at a particular angle with respect to the longitudinal axis of the handle. A band is provided which has two ends and a central portion. The central portion is located exteriorly of the handle and forms a loop to be placed around the tooth or other object. The ends pass through the aperture of the head portion into the hollow interior. A tightening lever is pivotally connected to the handle and the ends of the band for retracting the band through the aperture into the hollow interior, to tighten the loop around the tooth or other object to be measured.
