Summary
Temporomandibular disorders (TMD) did not show an association with speech issues in children. However, occlusal alterations were linked to speech sound distortions and incorrect tongue positioning.
Area of Science:
- Pediatric dentistry
- Speech-language pathology
- Orthodontics
Background:
- Temporomandibular disorders (TMD) can affect children's oral functions.
- Understanding the link between TMD, occlusion, and speech is crucial for diagnosis and treatment.
Purpose of the Study:
- To investigate the impact of TMD on speech in children.
- To determine the influence of occlusal characteristics on speech.
Main Methods:
- Assessed speech and occlusal characteristics in 152 Brazilian children (8-12 years old).
- Utilized Research Diagnostic Criteria for TMD (RDC/TMD) and a speech assessment tool for Portuguese.
- Categorized children into groups based on TMD signs and symptoms.
Main Results:
- No association found between TMD and speech disorders.
- Occlusal alterations were prevalent and associated with speech sound distortions (/s/, /z/) and tongue positioning issues.
- Reduced vertical jaw amplitude observed more in children with TMD symptoms.
Conclusions:
- TMD is not directly associated with speech disorders in children.
- Occlusal alterations are significant factors influencing speech sound production and tongue posture.
- Further research into the interplay of occlusion and speech development is warranted.
