[Histological aspects of the sagittal intermaxillary suture at different stages of development].

The Authors examined the histological structure of the midpalatal suture in seven individuals: two of the cases were foetuses, the others were children at the age of one day to two years. In the embryos and in the newborn children the suture was observed to be rather large and straight, while its width decreased with age. Moreover, no change in direction was observed, and the osteoblasts decreased in number.

[Comparative study of the intraoral pressure variations in normal subjects and in maxillofacial dysmorphosis patients].

The Authors examined the modification during swallow of the negative pressure in various areas of the mouth in normal individuals and in cases of malocclusion and malformations. A specially modified electronic device was used, and the measurements of compared in 25 cases. Abnormalities in pressure variation were found in cases of: 1) cleft of the lip and/or of the palate; 2) class III malocclusion presenting a law posture of the tongue; 3) lateral open-bite.
