The aim of this project was to study the craniofacial morphology, dental occlusion, dental maturation and tooth eruption in short-statured boys with growth hormone secretion ranging from low to high. The measurements from lateral and posteroanterior cephalograms, orthopantomograms and plaster models were used. Almost all linear measurements of the facial structures were significantly smaller. A disproportionate growth in the cranial base structures as well as in the jaws resulted in facial retrognathia, a proportionately smaller posterior than anterior facial height, and a steep vertical inclination of the mandible. Dental crowding was more common and the overbite was small. Dental maturity and tooth eruption were delayed 1.2 and 1.3 yr, respectively. No significant differences between the idiopathic short-statured and the growth hormone-deficient group in any of the above-mentioned variables were found. It can be concluded that although most of the cephalometric variables measured differed significantly from the average, the facial appearance of the boys is not conspicuous and is of minor clinical importance. However, the short-statured boys might be in greater need of orthodontic treatment due to the higher percentage of dental crowding.
