PRADO, Daniela Galvão de Almeida et al. Oral motor control and orofacial functions in individuals with dentofacial deformity. Audiol., Commun. Res. [online]. 2015, vol.20, n.1, pp.76-83. ISSN 2317-6431.  http://dx.doi.org/10.1590/S2317-64312015000100001427.

Purpose

To determine the correlation between oral motor control and orofacial functions in individuals with dentofacial deformity (DFD).

Methods

Sixteen individuals from 18 to 40 years, (average 28.37 years) participated. Seven individuals were class II (three women and four men) and nine were class III (five women and four men). They were evaluated for diadochokinesis (DDK) using the emissions /pa/, /ta/, /ka/ and /pataka/. The chewing, swallowing, and speech functions were filmed and analyzed by three speech specialists, using the MBGR protocol. The correlation results between DDK and the orofacial functions were obtained through the Spearman test.

Results

A positive correlation was observed between the DDK instability parameters in issuing the “pa” and “ka” and the chewing function. There was a positive correlation between swallowing and DDK for “pa” emission regarding the instability. As for the speed, there was a negative correlation for the DDK mean rate and a positive correlation for the average DDK period at “pa” emission. As for the speech, there was a negative correlation for “pa” emission for the instability parameter.

Conclusion

The oral motor control was related to the severity of the change in chewing and swallowing functions regarding the DDK speed and instability paramenters.
