[Evaluation of motivational factors of adolescent patients for orthodontic treatment using the Q methodology].

The management of adolescents in the orthodontic practice remains a challenge in terms of motivation and adherence to treatment. Some factors seem to be of paramount importance in the success of treatment. The objective of the present study was to evaluate the motivational factors of adolescent patients seeking orthodontic treatment using the Q methodology.

Cytotoxicity evaluation of dental and orthodontic light-cured composite resins.

Introduction: The aim of this study was to determine the cytotoxicity of light-cured composite resins (Clearfil ES-2, Clearfil ES Flow, Filtek Supreme XTE, Grengloo, Blugloo, Transbond XT, and Transbond LR) then to assess leachable components in contact with human gingival fibroblasts (GFs) and to quantity detected bisphenol A (BPA).

Methods: Light-cured composite resin discs were immersed for 24 hours in gingival fibroblastic medium (n = 3 for each product) and in control medium (n = 2 for each product) contained in plate. Cytotoxicity of the products (n = 95) was determined by the measure of cell viability using MTT assay after reading the optical densities of the plates.

Facial photogrammetric profile measurements and sagittal dental occlusion in the young Congolese Bantu Adult (DRC).

Objective: The aim of the present study was to determine, according to the kind of dental occlusion, the profile photogrammetric characteristics of the young Congolese Bantu adult (DRC Congo).

Materials And Methods: It was a cross-sectional study, including 302 young Congolese Bantu adults (161 males and 141 females), aged between 18-30 years old. All were in full permanent dentition, out of which 157 in dental normocclusion, 74 in distocclusion, and 71 in mesiocclusion.

[Formalized consensus: clinical practice recommendations for the management of the migraine in African adult patients].

Migraine is a primary headache disorder (according to the latest International Headache Society criteria) affecting approximately 8% of African population. Women are more often affected than men and attacks usually occur before the age of 40 years Although some treatments, hygienic-dietary measures and other non-pharmacological methods can reduce the intensity and frequency of attacks, medicinal treatment of migraine attack is often necessary. Availability of treatments and access to care differ in Africa and led to the implementation of the first expert consensus recommendations for the management of the migraine in african adult patients.

[Cephalometric characteristics of black African children 3-6 years of age with nasal obstruction].

Objective: To determine the cephalometric craniofacial characteristic of the child with chronic rhinopharyngeal obstruction.

Material And Methods: It is about a comparative cross-sectional study with etiologic aiming including children of the 2 sexes, old from 3 to 6 years. The pathological subjects are represented by those presenting a chronic rhinopharyngeal obstruction due to the presence of hypertrophied tonsils (n = 29) and the "normal" subjects, those without any rhinopharyngeal obstruction (n = 30).

[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.

[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.

[Cephalometric study of cranio-facial growth of 902 Black African children and adolescents aged 8 to 20].

Cephalometric studies of the growth are numerous and represent a contribution to the field of the anthropological knowledge of the stages of the cranio-facial growth and for a better adaptation of the orthodontic treatments. However, in Black Africa people there are very few studies of this kind. The purpose of this investigation is to analyze the growth of the cranial base, the maxillary skeletal region and mandibular skeletal region at the young African subjects.
