[A comparative study of breast feeding and artificial infant feeding by ultrasonic scanning].

Sucking process was examined in 22 breast- and formula-fed infants by ultrasonic scanning. Analysis of the obtained echographic images of the oral cavity along the middle sagittal line has led the authors to a conclusion that employment of traditional milk soothers with both large and small holes is harmful for articulation and forms an erroneous pattern of sucking and swallowing function, this possibly resulting in abnormal development of the jaws and oral cavity organs.
