Cephalometric evaluation in children presenting adapted swallowing during mixed dentition

Area of Science:

• Dentofacial Orthopedics
• Speech-Language Pathology
• Anthropology

Background:

• Adapted Swallowing (AS), characterized by tongue thrust and anterior projection during deglutition, is frequently observed during mixed dentition.
• Understanding the dentofacial morphology associated with AS is crucial for accurate diagnosis and treatment planning.

Purpose of the Study:

• To investigate the cephalometric characteristics of children with Adapted Swallowing.
• To analyze potential associations between dentofacial morphology, sex, and racial background in children with AS.

Main Methods:

• Cephalometric analysis was performed on 73 children (38 girls, 35 boys) aged 7–9 years diagnosed with AS.
• Measurements included mandibular and maxillary relations, nasolabial angle, upper airway patency, facial convexity, facial axis, and maxillary height.
• Data were analyzed using Radiocef 2.0 software, considering sex and racial variations.

Main Results:

• A significant association was found between Class II facial convexity and African Brazilian children with dark black skin.
• This finding suggests that current cephalometric standards, based on white populations, may misclassify other racial groups.
• No significant sex-based differences were noted in the studied cephalometric parameters.

Conclusions:

• Adapted Swallowing presents distinct dentofacial characteristics that may vary across racial groups.
• The study underscores the critical need for developing race-specific normative standards for cephalometric evaluation in pediatric populations.
• Accurate racial norms are essential for precise diagnosis and effective orthodontic and speech therapy interventions.
