Summary
Open mouth posture and abnormal swallowing patterns in children are linked to narrower dental arches and longer faces. These myofunctional habits can negatively impact dentofacial development, affecting overall oral health.
Area of Science:
- Pediatric Dentistry
- Orthodontics
- Myofunctional Therapy
Background:
- Myofunctional disorders can influence craniofacial development.
- Early identification of oral habits is crucial for effective intervention.
- Dentofacial development is a complex process influenced by various factors.
Purpose of the Study:
- To investigate the association between myofunctional variables and dentofacial development in rural second graders.
- To identify specific oral muscle functions related to dental arch form and facial height.
Main Methods:
- Correlational analyses were performed on data from 133 second graders.
- Measures included dental, skeletal, and oral muscle function assessments.
- Specific myofunctional variables like tongue and lip posture during rest and swallowing were evaluated.
Main Results:
- A significant relationship was found between open mouth posture and a narrow maxillary arch.
- Open mouth posture was also associated with increased facial height.
- Abnormal labial and lingual rest and swallow patterns correlated with poor lip and tongue movement coordination.
Conclusions:
- Myofunctional habits, such as open mouth posture, are significantly associated with specific dentofacial characteristics.
- These findings highlight the importance of assessing oral motor function in pediatric dental and orthodontic evaluations.
- Early intervention for myofunctional disorders may help mitigate negative impacts on craniofacial growth.
