Posturography as a diagnostic aid in dentistry: A systematic review

The aim of this systematic review of the literature was to assess the scientific evidence for detectable correlations between the stomatognathic system and whole-body posture and to provide information on the relevance of posturography as a diagnostic aid in dentistry. A literature survey was performed using the Medline database, covering the period from January 1966 to May 2009, and using the medical subject headings. After selection, 21 articles qualified for the final analysis. Only one study was judged to be of medium/high quality, with all of the rest classified as of low quality design. Only two studies included follow-up of 28 days and 1 year. Overall, 14 of the studies reported detectable correlations between the stomatognathic system and body posture in at least one of the parameters used, although in four of these studies the authors suggested caution in the interpretation of their data. After a reappraisal of the data provided in 13 of the studies, a weak correlation that re
