Title Resonance Frequency Analysis (RFA) Can be An Adjunct in Diagnosing Anklyosis in The Primary Dentition
Clinical Question In patients with suspected ankyslosed teeth how does RFA (resonance frequency analysis) compare to radiographic analysis in diagnosing ankylosised teeth?
Clinical Bottom Line As there is no adequate gold standard to diagnose ankylosis, RFA gives the clinician another means for monitoring and helping diagnose ankylosis.

22607343Bertl/201215 ankylosed primary molars & 30 control primary molarsCase Control Study
Key resultsThe study sampled 45 primary molars, 15 diagnosed ankylosed primary molars, and 30 control primary molars (primary molars with no signs of ankylosis). The reported sensitivity was 53.3%. The reported specificity was 100%. The reported AUC was 0.807. A patient survey indicated that 80% of patients considered this test very comfortable, and the rest considered the test minimally uncomfortable.

The Evidence
Validity: Further research is needed to narrow ISQ (implant stability quotient) values for ankylosed teeth to allow for an increase in sensitivity. This study represents a study in primary molars only and needs further research to apply to ankylosis in the permanent dentition. Also, the sample size is small and another study with a larger sample size is needed. Perspective: Due to a lack of a “gold standard”, RFA may prove to be another tool to diagnose ankylosis. Also, the ability to quantify ankylosis with the ISQ numbers can help the clinician see the progression and allow for more predictable time table for treatment.
Applicability If the clinician has access to an RFA unit such as Osstell or Perio test, it may be beneficial as an adjunct to radiographs and clinical experience in diagnosing ankylosis. Also, as ankylosis isn’t an “all or nothing” phenomenon, RFA offers the first means of quantifying and monitoring the severity of ankylosis.
