[Orthodontic studies in children with stunted growth]

Biometrical studies on a group of 43 children with stunted growth showed that stunted growth is associated with smaller dimensions of the upper dental arch. The lower dental arch is not involved. The relationship between the variations in the characteristics under examination are explained with the aid of three basic factors of growth which had been established mathematically. The crown diameters of the permanent teeth are not smaller as in children with normal growth.
