We studied the number and expression of plicae, the direction of their spreading and the shape and size of their areas in the study models of 432 children from Niš. The same numbers of plicae in both sides were registered in 56.48%, most often in the combination of 4+4 (55.74%). Different numbers appeared in 43.52%, where the combination of 3+4 dominated (78.72%). The plicae in the first two pairs were medium-expressed in 74% and highly expressed in 23.15%. Other plicae were generally poorly expressed (58.27%). The direction of their position was mainly mesial (almost 70%) for all the pairs of plicae, or it was combined with the straight or, rarely, distal directions. The areas of all the plicae were wave-shaped in 87% and wave/y-shaped in 29%. The area size varied in both directions, it ranged from 8-15 mm, most frequently 11 and 12 mm (56.41%) in the transversal, while in the sagittal plane it was 10-17 mm, with the value of 14 mm in 30%. The individual variability of palatal plicae is very high, and there is no uniformity even in MZ twins. .
