[Cranio-cervical posture and hyoid-mandibular-pharyngeal equilibrium in the presence of factors related to respiratory dysfunction].

Aim: The goal of this study is to know the modifications of the cranio-cervical posture which accompany the functional anomalies by the nasal breathe of black African children.

Material And Method: The study consists of a cephalometric comparison. Sixteen parameters measured on cephalograms of 98 schoolboys from 6 to 15 years were used.

Comparative cephalometric study of three different ethnic groups of black Africa with normal occlusion.

Introduction: The aim of this study was to investigate if there are differences or not between African ethnic groups in order to determine any ethnic and regional differences in the facial morphology.

Material: Lateral cephalograms of 53 young Ivorians, 50 young Senegalese and 62 young Chadians, obtained under the same conditions in each country, were measured. Ten skeletal, eleven dento-skeletal and twelve soft tissue variables were investigated.

[Three-dimensional imaging of root axes in patients from X-ray computed tomography slices].

The authors propose to materialize the corono-radicular axes of the teeth starting from their centre of gravity. This last is calculated with the data of the matrix of inertia resulting from the segmentation from tomodensitometric cuts (TDM). The sample is composed of 37 subjects (16 women and 21 men) old from 15 to 65 years, pertaining to a orthomorphic population.

[Treatment of class I malocclusion with severe dento-maxillary dysharmony in the permanent dentition of young black African patients].

Class I malocclusion with severe dental crowding can constitute a serious psychosocial and functional damage among young patients; from where orthodontic importance of the treatment. In the present study the authors present the treatment of two clinical cases whose initial problems are similar. They are two cases of class I malocclusion but whose certain diagnosed clinical factors have constrained in a case to control to the maximum anchoring on the level of the molars and in the other to control the dental axes.

[Prevalence of rhino-pharyngeal disease in the presence of malocclusion in school children in the village of Abidjan].

An epidemiological survey of randomly selected school children led to Abidjan in three public schools made it possible to determine the prevalence of the rhinopharyngeal diseases in presence of malocclusions. It is an exploratory study jointly undertaken by two teams of specialists in ORL and Orthodontics within a sample of African schoolchildren old of 5 to 21 years. The results showed the presence of malocclusions in 73.
