Abstract
Objective: Dysfunctional swallowing may cause transverse occlusal disorders. The speech re-education of dysfunctional swallowing aims to correct or prevent the recurrence of occlu­sal disorders. The main objective was to test the dynamic palato­graphy as a diagnosis and quantification tool of the dysfunctional swallowing.
Material and methods: The study was prospective and descriptive. Twelve average 23.5 years old women with a clinical dysfunctional swallowing have been included between January and May 2014. None was aware of presenting an atypical swallowing or dento-facial dysmorphism of class II. The dynamic palatography device measured the pressure force of the language on the palate during the lingual rest, swallowing saliva and water. Parameters measured were the duration and magnitude of support of the tongue on the palate.
Results: Dynamic palatography showed a trend to predominant anterior contact during rest position (25%), and lower position of the language with little contact during swallo­wing of saliva and water.
Discussion: Palatography results are consistent with the clinical diagnostic criteria of atypical swallo­wing. Our palatography tool has the advantage of being unobtrusive in the mouth compared to other pre existing systems. This device should be tested on larger patient popu­la­tions and could enable monitore atypical swallowing rehabili­ta­tion efficiency. The palatography could complete the swallo­wing assessment and be a monitoring and rehabilitation tool in real time.
