Applications and results using the Nordic Orofacial Test-Screening protocol

Birgitta Bergendal*, Anita McAllister


Orofacial function includes a multitude of actions, some of them vital, such as breathing, chewing and swallowing, and acts as the basis for social interaction in terms of speech, emotional communication, facial expression and appearance. Impaired orofacial function is a common feature in many inherited disorders or may be acquired as a consequence of disease and trauma. NOT-S is a comprehensive method for screening of orofacial function developed by a Scandinavian network of dentists and speech and language pathologists.


To present current applications and results from publications on the use of NOT-S. 

Materials and Methods

Beside the method study published in 2007, which showed good inter- and intraexaminer agreement, to date four studies were published. One was a study in individuals with Parkinson´s disease (n=15), two were studies in individuals with rare disorders; Ectodermal dysplasia (n=46), and Prader-Willi Syndrome (n=45), and one was a study evaluating surgical treatment in children with tonsillar hyperthophy (n=67). Total NOT-S scores in the twelwe domains of NOT-S were plotted and shown as dysfunction profiles for the different conditions.


The groups with different diagnoses showed specific dysfunction profiles indicating patterns of domains with impaired orofacial function. The use of NOT-S to assess orofacial function before and after surgery in children with tonsillar hypertrophy showed that the method can also be used to evaluate interventions.


Screening with NOT-S proved to be a quick and reliable way of assessing orofacial function which discriminated well both between groups with different diagnoses and in evaluation of treatment.
