— The purpose of the present study was, by using a standardized radiographic technique, to assess the time of selected mineralization stages of all permanent teeth except the second and third molars in a group of 580 children aged 3–7 years. A complete radio‐graphic examination, consisting of nine intraoral films, was made of each child, using Eggen's film holder. According to degree, mineralization of the teeth was subdivided into nine stages. The cap relation between the two variables, mineralization stage and chronologic age, was calculated by linear regression analysis. The hypothesis of the present study, that linearity exists between the two variables, was confirmed within and close to the investigated age group.
