Exploring Developmental Interactions Between Speech and Orofacial Functions in Preschoolers: A Cross‐Sectional Study

BACKGROUND: Speech and orofacial functions (breathing, swallowing, and chewing) both develop within the stomatognathic system and share common anatomical structures and motor control mechanisms. Theoretical models suggest that early orofacial motor experiences may shape speech development. However, empirical evidence examining these relationships during the preschool years remains scarce. AIMS: This study explored the relationship between speech and orofacial functions in preschool children. We hypothesised that this relationship is not direct but indirect, with oral motor competence, operatio
