“…Methods for measuring tooth mobility include the evaluation of tooth movement under application of a defined load (24, 28, 29), use of the Mühlemann periodontometer (14), and use of the Periotest device (15, 17, 19, 25). The Periotest method is a well established and accepted technique for measuring tooth mobility in both periodontology (30–34) and dental traumatology (15, 17, 19, 25, 35–37). The advantages of this method are easy application, the ability to measure both horizontal and vertical dimension, and highly reproducible results (14).…”
