Abstract:
This study verified the influence of chronic mouth breathing on dentofacial growth and developmental in pre-school children. The study evaluated 73 children, both sexes, ranging from 3 to 6 years of age. After the otorhinolaryngological breathing diagnosis, 44 mouth-breathing children and 29 nasal-breathing children were compared according to facial and occlusal characteristics. The skeletal pattern measurements SN.GoGn, BaN.PtGn, PP.PM, Ar-Go, S-Go indicated a tendency to mouth-breathing children presenting a dolicofacial pattern. According to occlusal characteristics, only the intermolar distance showed a significant correlation with a narrow maxillary arch in mouth-breathing subjects. Based on the results of this study, mouth-breathing can influence craniofacial and occlusal development early in childhood.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
