Aim: the purpose of this study was to analyse the crown morphology of maxillary central incisors in cases of agenesis of the upper lateral incisors, in order to establish patterns of associations between redu- ced mesio-distal dimensions of anterior teeth and tooth abnormalities in number. Materials and methods: the sample consisted of 31 patients with unilateral and bilateral absence of maxillary lateral in- cisors. Ninety six subjects without any agenesis were included in the control group. Mesio-distal widths of each central incisor crown we- re measured by means of 2 parameters; at the apical third of the crown and at the contact point. A Student’s t test was used to compare the results of each measurement within both group. Results: Significant differences were found in mesio-distal diameters at the contact points but not in the mesio-distal diameter at the apical third of the crown. Conclusions: It could be suggested that in case of cases of agene- sis of the lateral incisors the central incisors show a rectangular sha- pe of the crown instead of the trapezoid shape in subjects without age- nesis. These remarks should be considered before the orthodontic-pro- sthetic treatment is planned. A Olivadoti, T Doldo, M Treccani.
