Abstract:

PURPOSE: This research is aimed at relating the production of linguodental phonemes (/t/, /d/, /n/ and /l/) to the mobility of the tongue in 125 male and female children who were aged 4.0-8.11 years old. CASE REPORT: The research was based on protocols from a specific database. Parents and/or guardians responsible for the children authorized their participation by signing free and clarified consent forms. The children had been diagnosed with a phonological disorder (PD) and with alterations only in the stomatognathic system (SS). The results were correlated with the period before treatment. The phonological system has been evaluated through the phonological evaluation of children (FEC) and the gravity was analyzed through the Percentage of Correct Consonants-Revised (PCC-R). The sample was divided into 4 main groups of segments (/t/, /d/, /n/ and /l/) that were subdivided into three groups: acquired phoneme, partially acquired phoneme, and absent phoneme. In the SS evaluation, alterations in the mobility of the tongue were verified, among many other aspects. A statistical analysis was performed through the Mann-Whitney U test by using the statistical software Statistic 9.0 (p < 0.05% was considered statistically significant). It was possible to verify the nonexistence of a statistical relation between the production of linguodental phonemes and the mobility of the tongue. CONCLUSION: These findings suggest that the production of the phonemes /t/, /d/, /n/ and /l/ and the mobility the tongue are unrelated.
