Background. Masticatory system and speech sound disorders concur, have the same causes and similar consequences – both increase the risk of dental and periodontal diseases.
Objectives. The study was conducted to establish the correlation between functional disorders of the masticatory system and speech sound disorders.
Material and Methods. Three hundred patients aged 7–10 years were examined to detect functional disorders of the masticatory system and speech sound disorders. Functional disorders were assessed in patients with and without speech sound disorders.
Results. According to the study results, functional disorders of the masticatory system concur more often with speech sound disorders than with correct articulation and lead to speech sound disorders. There is a strong correlation between: – any dysfunction and errors in the /p/, /b/, /m/, /s/, /z/, /t͡ s/, /d͡ z/, /ɕ/, /ʑ/, /t͡ ɕ/, and /d͡ ʑ/ sounds, – mouth breathing and errors in the /p/, /b/, /m/, /s/, /z/, /t͡ s/, /d͡ z/, /ɕ/, /ʑ/, /t͡ ɕ/, and /d͡ ʑ/ sounds, – persistent tongue thrust and errors in the /s/, /z/, /t͡ s/, /d͡ z/, /ʂ/, /ʐ/, /t͡ ʂ/, /d͡ ʐ/, /ɕ/, /ʑ/, /t͡ ɕ/, and /d͡ ʑ/ sounds, and – parafunctional sucking and errors in the /s/, /z/, /t͡ s/, /d͡ z/, /ʂ/, /ʐ/, /t͡ ʂ/, /d͡ ʐ/, /ɕ/, /ʑ/, /t͡ ɕ/, and /d͡ ʑ/ sounds.
Conclusion. To implement effective and early prevention and treatment, it is crucial to know the correlation between the masticatory system and speech sound disorders, as it reduces treatment duration and minimizes relapses of not only communication disorders, but also of concurrent masticatory system disorders.
