Resonance frequency analysis (RFA) can quantify the rigidity of the dental implant\u2010to\u2010bone connection and thus may serve as a potential diagnostic tool to identify ankylosed teeth. To test this assumption, we examined 15 and 30 primary mandibular molars, with and without clinical signs of ankylosis, using the Osstell Mentor system. A cut\u2010off implant stability quotient (ISQ) of 43 provided a specificity of 100% and a sensitivity of 53.3% when measured in the mesio\u2010distal direction or a sensitivity of 20% when measured in the bucco\u2010lingual direction. Based on a receiver\u2013operating characteristic (ROC), the area under the curve (AUC) of 0.807 showed the mesio\u2010distal direction of measurement to be a test of moderate discriminatory power. Given its non\u2010invasiveness, RFA may serve as a quantitative diagnostic supplement to the clinical examination of potentially ankylosed primary molars.<\/jats:p>","DOI":"10.1111\/j.1600-0722.2012.00959.x","type":"journal-article","created":{"date-parts":[[2012,4,21]],"date-time":"2012-04-21T09:13:24Z","timestamp":1334999604000},"page":"255-258","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Resonance
