[Comparison of the perception of esthetic and orthodontic treatment need between an African and a Caucasian population].

INTRODUCTION: Improvement of dentofacial appearance is often the main motives of patient seeking orthodontic treatment. However perception of aesthetic and orthodontic treatment need may be different among populations of different cultural background. The aim of the present study was to compare the perception of aesthetic and orthodontic treatment need between Caucasian (French) and African (Senegalese) MATERIALS AND METHOD: In the present study the perception of the attractiveness of 98 colours photographs of dentitions were assessed by 34 Caucasian and 31 African lay judges by mean of a Power Point presentation. Each slide were displayed for evaluation during 20 seconds RESULTS: The two populations share the same perception of orthodontic aesthetic with respect to some occlusal traits. However they diverge in their appreciation of 70% of the dentitions with midline diastemas. There were also significant differences in the perception of orthodontic treatment need with the Caucasian judges suggesting treatment more often than Africans. CONCLUSION: The results are discussed in term of accessibility in orthodontic treatment in association with socioeconomic status.

[The need for orthodontic treatment. Justification and methods of evaluation (part 1)].

Most adolescents in developing countries undergo orthodontic treatment. Three main reasons are routinely cited to justify the provision of orthodontic treatment i.e. the improvement of facial and/or dental aesthetic, the preservation of the health and functioning of the dentition. Orthodontic indices have been devised to minimise the subjectivity related to the classic orthodontic diagnosis. These indices can be classified under five headings: nosological, epidemiological, treatment need, outcome and complexity.

[Orthodontic treatment need: the IOTN, or Index of Orthodontic Treatment Need (part 2)].

IOTN is an index of orthodontic treatment need that has been devised on the basis of the available evidences of the deleterious effects of malocclusion on the aesthetic and health of the dentition. It has two components i.e. an aesthetic component and a dental health component. This index is widely used in epidemiological research and by third party payment for determination of those patients who should benefit from public funding.

Mixed dentition analysis in a Moroccan population.

The aims of this study were to produce odontometric data for a Moroccan population, to test Tanaka and Johnston and Moyers methods, to derive regression equations and elaborate a specific orthodontic prediction table for Moroccan children. 50 dental casts of Moroccan students (25 males, 25 females, mean age 22.6 years sd 1.35) were used to perform measurements of the greatest mesiodistal widths of all mandibular and maxillary canines and premolars and mandibular incisors with an orthodontic calliper. Significant sexual dimorphism was found in tooth sizes (p = .001). The study revealed close relationships between the total mesiodistal widths of the mandibular permanent incisors and that of the maxillary and mandibular canines and premolars. The correlation coefficients (r) and the coefficient of determination (R2) were better sexes combined for the maxilla (r = 0.60 ; R2 = 0.36 ) and for the mandible (r = 0.61 ; R2= 0.37). The regression equations elaborated for males and females were used as a basis for establishing an orthodontic prediction table for Moroccan children.

[Surgical and orthodontic treatment of inclusions and dental retentions: report on the upper incisives and canines block].

We have consecrated this retrospective report to the clinical study and treatment of 18 cases of inclusions and dental retention observed in the services of orthodontics and oral surgery of the department of odontology of the medical faculty of the Dakar University. From that study it arises that 50% of the inclusions and retentions are casually discovered and that canines and central incisives take up to the first place. With regard to the surgical treatment associated to orthodontics, it is only seldom worked up because of its duration and the late appearance of the results. However it agrees to retain that the treatment of these affections can be conceived only in the point of view of a multidisciplinary approach.

[Treating five cases of Class III skeletal brachygnatia maxilla with the Delaire mask].

Class III skeletal abnormalities are known as sagittal defects and they are recognized by a hollow profile, which is an unesthaetical morphological distorsion often ill--accepted by the patient, a severe disability. Due to the large number of clinical patterns, it is crucial to make an accurate diagnosis. Class Ill skeletal abnormalities involving a maxillary brachygnatia are caused by an insufficient development of the jawbone. Treatment will therefore consist in boosting growth of the lower back section of the jawbone. The external device known as Delaire mask which stimulates growth of the lower back section of the jaw is particularly recommended to achieve this. This piece of research set out to assess the effectiveness of this method based on five of our patients. Outstanding results were obtained, namely alveolar ridge slided forward on the jawbone, improved profile (a cutaneous Class I is obtained), and a disappearance of the occlusion, along with a correction of the inverted backward bite. When adequately prescribed, the use of the Delaire mask, as opposed to corrective surgery, leads to a slow and gradual improvement. Furthermore, results achieved among young children blend into their own natural growth. By resorting to early treatment with the mask, it is possible to avoid falling back on complex surgery, which would almost necessarily be of the orthognatic type among adults.

[The health of the child during eruption of the deciduous teeth].

Teething is a physiological process that may be marked by local regional or general physiopathologies. We have studied these disorders in a sample of 499 children whom we followed from the age of 5 until the age of 30 months. The study consisted in a clinical endobuccal examination. Each month we recorded the order and the eruption date of the tooth or teeth and the disturbances that arise during the process or after, if any. We expose the results of this study in this paper. We collected local and general disturbances during the primary teeth eruption period. We considered that in certain conditions these disturbances could be to the eruption process. Teething is certainly a natural process, however considering its traumatic impact on the young child, we should not reject the aetiology in the justification of the disturbances observed in this process and seek another one which might not be valid.

[Discriminating factors of mandibular divergence].

The aim of this work is to identify the discriminating factors of mandibular divergence. 90 patient records taken from the 98--99. 99--2000 files in the orthopedic dentistry service of the Department of Odontology at Dakar University were examined. The patients selected were all of Black African descent and aged from 11 to 13. This work consists in the cephalometric examination of X-ray profiles radiographis in order to compare various elements between normodivergent and open-bite subjects. The statistical analysis of data along with various tests carried out led to the following conclusions: - Measuring FMA. GOI-Me/Oli, GOI-Me/Pocc, Ans-Pns/GOI-Me and chin angle can be used to discriminate between open-bite and normodivergent patients. - SN/GOI-Me has a positive correlation with GOI-Me/Oli, GOI-Me/ Pocc, Ans-Pns/Pocc, Ans-Pns/GOI-Me and FMA. - The chin angle has a negative correlation with the previous forms of measurements. - The correlation between Ans-Pns/Pocc and the other measures is weak. - The average difference between the measures of both groups is important, which means that these variables discriminate between normodivergent et open-bite patients. BIased on the most discriminating variables, we produced the following function of classification: F= - 1,542 -0,095(Angle) + 0.098(Ans-Pns/GOI-Me) + 0,145(FMA) We have also established an equation of probability for a patient to be normodivergent or open-bite, which is as follows: Pr (Normal) -----------=e(-0.273 FMA -0.267 ANS-NS/MEGOI +0.272 ANGLE) Pr (hyper)

[Chronology and date of eruption of primary teeth in Senegal].

Chronology and eruption dates of primary teeth are parameters of importance in different medical scientific fields. We carried a longitudinal clinical study to determine these parameters in a local Senegalese population. The study interests a sample of 573 Senegalese Negro children of the two sexes and its aims are to situate these parameters formally and in space in on hand, and to be able to justify; in comparison to these parameters, the disturbances which accompany often the phenomenon of dental eruption in the other hand. We have results relating to chronology and eruption date of the 20 primary teeth of each of the children. Our study strengthens data already known but it reveals also other data as well as important. Other studies are however necessary to set a good board of chronology and eruption date of primary teeth in the Senegalese population.

[Prevalence of dental agenesis: a radiologic and clinical study in Dakar].

A total of 1007 files were studied with regard to the prevalence of congenitally missing teeth. All patients were radiographed. 4.56% were found to have at least one congenitally missing tooth. The lower second premolar was the most commonly missing tooth in this study (41.66%), followed by the upper lateral incisor (22.2%). The prevalence and the distribution of dental agenesis between male and female was similar.

[Epidemiologic study of the causes of esthetic restorations in pedodontic clinics in Dakar].

The authors expose a retrospective study carried out on records of patients from 18 months to 15 years old consulting for esthetic restorations in 3 dental health care centers of Dakar. The total number sampled is 151 children with 89 boys and 62 girls representing 3.5% of the total number of consultants [3964] during two years [1991 and 1992] in the dental health care centers. The study shows that the main etiological factors of the esthetic restorations in constant progression, are dental traumatisms, and caries infections. It shows also that the request varies with age and sex and that the male are more represented in the sample. Face to the lack of structures, material and human means, information, education and communication for the oral and dental health have to be fully broadcasted in the kindergartens and elementary schools in the limit of an entire prevention program in order to reduce the needs in this precise field.
