Mesiodistal size of deciduous teeth in subjects with unilateral cleft lip and palate.

The aim of this study was to investigate whether there was an association between presence of a cleft and reduced size of deciduous tooth on the cleft side. In this investigation, 58 study models of patients with unilateral cleft lip and palate with deciduous dentition were analyzed. The largest mesiodistal dimension of deciduous teeth was measured by a sliding caliper. The size of the same teeth on the side of the cleft and on the non-cleft side was compared. The results of the investigation were statistically analyzed. A difference between the genders was found. In the sample of boys the lateral deciduous incisor and the second deciduous molars on the cleft side were smaller than those on the non-cleft side, while in girls the central and lateral deciduous incisors were smaller on the cleft side than on the non-cleft side. It was concluded that the presence of a unilateral cleft lip and palate was associated with smaller tooth size.

An extra X chromosome effect on craniofacial morphogenesis in men.

A comparative study of the craniofacial complex in men with an extra X chromosome, and normal male and female individuals was carried out using cephalometric radiography. The anterior cranial base, anterior and posterior facial height, maxillary base and ascending ramus were found to be significantly decreased in men with Klinefelter syndrome when compared to the male control group. Significant differences in the lengths of mandibular base and posterior cranial base were not found. When compared to the female control, all structures examined were significantly increased, except for the maxillary base.

[Variations of sagittal skeletal relationships in cases with normal occlusion].

Cephalometric radiographs of a sample of 92 cases with normal occlusion were used to study variations in the sagittal jaw relationship. The Schwarz's and Steiner's cephalometric methods of analysis were employed. Results obtained by the Schwarz's method showed that 58.7% of cases had Class I, 16.3% Class II and 25% Class III skeletal relationship. On the other hand, the Steiner's method demonstrated Class I skeletal relationship in 59.8% cases, Class II skeletal relationship in 8.7% of cases and Class III skeletal relationship in 31.5% of cases. Both cephalometric methods indicated Class I skeletal relationship in 39.1% of all cases investigated. In addition, both methods showed the same skeletal relationship (Class I, Class II or Class III) in 58.6% of all cases investigated.

[Growth changes of some craniofacial dimensions].

A longitudinal investigation was done on the sample of 14 children, both sexes between seven and ten years of age. Lateral cephalometric roentgenograms, taken once a year under the same conditions, were used for this analysis. It was found that SNA angle decreased, and SNB angle increased during the growth period investigated. The maxillary plane inclination increased and the mandibular plane inclination decreased during this period. According to the Björk's poligon analyses anterior growth rotation was found. All the linear measurements investigated increased with the age, but statistically significant difference was found only for the length of maxillary base and the upper face height.

[Craniofacial dimensions and growth. Longitudinal study].

On a sample od 13 children of both sexes, aged 5-7 years, the longitudinal investigation of eight angular and five linear dimensions was carried out. Lateral cephalometric roentgenograms were used for the analyses. It was found that during the investigated period maxillary and mandibularly prognathism increased, maxillary plane inclination increased, and mandibular plane inclination decreased. None of the examined angular measurements showed a statistically significant difference in the age between five and seven year. All linear measurements increased with the age and grown. Statistically significant differences were found only for maxillary base length and upper face height.

[Craniofacial characteristics of children affected with juvenile rheumatoid arthritis].

The aim of this investigation was to determine the craniofacial characteristics of children affected with juvenile rheumatoid arthritis. The analysis concerned the profile cephalometric roentgenograms of 11 children of both sexes aged between five and ten years. Statistically significant differences between affected and healthy children were found for saddle angle, articular angle, Björk's sum of posterior angles and maxillo-mandibular angle.
