Abstract
In a longitudinally surveyed sample consisting o f 51 subjects with and 25 subjects without coronary crowding, aged 11 to 13, 6 standard gnathometric variables, Angle classes developmental level o f apical base o f maxilla and o f the orthodontic status found before the replacement o f teeth were analyzed. The purpose o f the study was to identify relevant factors responsible for the development o f crowding, as well as to recognize its early symptoms. The results o f the study showed the following: - mean sagittal and transversal dimensions o f the upper dental arch was significantly lower in subjects with coronary crowding; - in both groups o f subjects, class I was most frequently found, with coronary crowding it was mostly class II/l, and without it class II/2 and class III; - apical base development level most often coincided with the development o f dental arch; - coronary crowding in deciduous dentition and a very early loss o f primary teeth might be an early indication o f later coronary crowding; - carious and nonrestored deciduous teeth favored crowding in permanent dentition.
