ABSTRACT
There have been numerous studies of facial esthetics, but few have benefited from the new techniques provided by 3D imaging. The aim of this study is to determine which are the most crucial cephalometric criteria for facial esthetics by identifying the strongest correlations between the esthetic rating and 3D Cephalometric values, the Cepha 3Dt. A group of 91 subjects (from 10 to 60 years of age) was rated by a jury of 50 randomly selected judges (from 12 to 65 years of age) using an analog scale. We then looked for the most important correlations between the esthetic ratings and the tridimensional cephalometric values by using 3D Cephalometric Analysis on a global sample, and on Class II and Class III sub-samples. Facial esthetics therefore appeared to be especially linked to: anterior-posterior dimension, maxillo-mandibular disharmony, relationships between the anterior areas (alveolar and basal), the alveolar region has a greater impact than the basal area on facial architecture. In the Class II group, sagittal discrepancies and mandibular divergence have an equal impact on the assessment of facial esthetics.

THE OBJECTIVE: To compare the tocolytic action and the side effects of nicardipine to those of salbutamol in patients presenting premature labor in order to propose nicardipine as a promising alternative to salbutamol in the treatment of premature labor. METHODS: forty eight patients admitted for premature labor were included in this prospective randomized study comparing nicardipine and salbutamol, administered with intra venous drip. The nicardipine group included 25 patients and the salbutamol group included 23 patients. RESULTS: the epidemiologic characteristics of the 2 groups are similar. No significant difference between the 2 groups was noted in the average time of disappearance of the uterine contractions. In nicardipine group, the pregnancy was prolonged more than 48 hours in 87.5% of the cases against 85.8% in salbutamol group (P: NS). Adverse effects linked to tocolysis were recorded. In nicardipine group, 8% of the patients presented an intolerance of the molecule, against 47% of salbutamol group, the difference is significant (P = 0.02). The term of delivery was similar in both groups The neonatal status of the infants was identical in the two groups. In the group of new born hospitalized, we did not note biological disorders concerning the glycemia and the calcemy. CONCLUSION: nicardipine is at least as effective as salbutamol in tocolysis; but it has lest secondary effects. Thus, nicardipine is proposed as the tocolytic of first intention instead of the salbutamol which is considered as reference molecule.
