[Relationship between bizygomatic width and the size of maxillary anterior teeth among young Senegalese black people recruited in army]. / Corrélation entre la distance bizygomatique et la largeur des dents antéromaxillaires chez les jeunes sénégalais mélanodermes recrutés dans le service militaire.

INTRODUCTION: Prosthetic teeth size and placement must be in perfect harmony with the bucco-facial structures for a successful and esthetic removable prosthesis. This study aimed to determine among young Senegalese black people facial index estimating maxillary central incisor width and distance between canine points starting from bizygomatic width. PATIENTS AND METHODS: 621 black Senegalese participated to this transversal study. Measurements were made using anthropometric slide caliper and electronic slide caliper. The comparative analysis was carried out by the test t of Student. The correlative analysis used the chi-square test. The risk of error was fixed at 5%. RESULTS: Positive correlations were found between variables. Distance between canine points was significantly (p = 0.000) correlated to bizygomatic width and central incisor width. Using bizygomatic width, the average dividing factors to estimate central incisor width and distance between canine points were respectively 15.13 and 3.75. CONCLUSION: Distance between canine points and central incisor width can be given starting from bizygomatic width, as guide of selecting maxillary anterior prosthetic teeth width.

[Correlations between colorimetric parameters of teeth, eyes and skin. Perspectives in the choice of tooth shade for complete denture]. / Correlations entre les parametres colorimétriques des dents, des yeux et de la peau. Perspectives dans le choix de la teinte des dents en prothèse adjointe complète.

Rehabilitation with complete denture include among other objectives, improvement of facial and dental esthetics. To these ends, the artificial teeth should mimic as far as possible, healthy and natural dentition. The main objective of this study was to investigate factors associated with tooth color among black African subjects. One hundred and two subjects (72 men and 30 women) were included in this investigation. The colorimetric parameters of their teeth as well as those of the conjunctiva of their eyes and skin were recorded from standardized photographs. Two software, Mesurim and Photoshop were used for that purpose. Univariate and linear regression analysis were run to assess the association between tooth color and the variables age, gender and colorimetric parameters of eyes and skin. It appears from the result of this study that tooth color was positively and significantly associated with age. Stepwise multiple regression analysis further revealed that tooth hue can be best predicted by a combination of skin complexion and brightness and eye lightness.

[Relationships between masticatory performance and nutritional state in complete denture wearers]. / Relations entre Performance Masticatrice et Etat Nutritionnel chez des Sujets Porteurs de Prothèses Complètes.

UNLABELLED: For many authors masticatory dysfunctions are related to reduction in dietary intake with malnutrition as a possible consequence. The aim of the present study was to further investigate the relationships between masticatory performance and nutritional state in complete denture wearers. METHOD: Masticatory performance was assessed using a granulometric method in 74 subjects divided into 2 subgroups according to their dental status (normal dentition and complete dental wearers). Nutritional status of study subjects was analyzed with Mini Nutritional Assessment (MNA). RESULTS: There were a significant association between wearing denture and Nutritional Status as assessed by MNA. Using this scale, a risk of malnutrition was found in 80% of subjects wearing complete denture and in 26% in the normal dentition sub group (p < 0.0001). There were also a positive and significant correlation between, the particle size distribution and masticated test food and nutritional status. CONCLUSION: Complete denture wearers are at greater risk of malnutrition than did subjects with normal dentition.

[Study of mastication in denture wearers among various ages]. / Etude des parametres physiologiques de la mastication chez des sujets ages porteurs de protheses adjointes completes.

INTRODUCTION: Recent studies have shown that it was possible for subjects with masticatory deficiency chewing achieve a satisfactory level of fragmentation of food by acting on some physiological parameters as the number of cycles and the time devoted to a sequence of mastication. METHOD: The objective of this work is to study the effects of the wearing of complete prostheses, of ageing on the physiological parameters from the chewing on a population of 110 subjects. RESULTS: The results show an important effect of the dental status. Indeed denture weaers need twice more cycles than controls of the same age to make a ham portion ready to be swallowed. Significant an age effect with regard to the number of cycles was also noted. The rheology of food affects the number of cycles which increases with the hardness of food.

[Study of the characteristics of the food bolus in elderly subjects with complete dentures]. / Etude des caractristiques du bol alimentaire chez des sujets agés porteurs de prothèses complètes.

Many studies have shown that wearing of complete dentures impairs masticatory function. The aim of this study was to investigate the influence of complete denture wearing and ageing on masticatory performance. Masticatory performance was assessed by a granulometric method on 110 subjects divided into 3 groups according to dental state and age. The results show edentulous subjects have a masticatory performance worse than their congeneric of the same age. Indeed, the median of the distribution of the size of the particles is more important at the carriers of prostheses than at the toothed old subjects (P < 0.0001). On the other hand the extent of the distribution does not vary significantly between these 2 groups of subjects. The parameters of the masticatory performance do not vary in a statistically significant way between the old subjects and the young controls. There is thus no significant effect of the age on the parameters of the performance masticatory.

[Evaluation of rehabilitation needs by post-maxillectomy prosthesis in Senegal]. / Evaluation des besoins de réhabilitation par prothèse maxillo-faciale obturatrice après maxillectomie au Sénégal.

The surgical treatment of the jawbone tumors often ends up with an communication between the mouth and the sinus, embarrassy for the function and carrying severe esthetical damages. This work aims to evaluate the needs in filling mouth and fixe treating prosthesis in the management of malignant tumors at the Dantec University hospital. A case study of maxillary jawbone cancers observed in the ORL and the stomatology services allowed us to observe on a ten years period, 91 cases of maxillary cancers, from which (29 or 31.86%) have been surgically treated and only 3 patients (3.29%) got a full mouth and face filling prosthesis. Those patients averaged 50 years old, but we have registered some younger patients and women who, having missed oral rehabilitation, are really handicapped. In Senegal the care of people suffering from jawbone cancers must include a surgical section as well as a radiotherapeutic one, in order to involve all the cases, and a filling mouth-and-face rehabilitation prosthesis.

[Clinical evaluation of the occlusion of young Senegalese]. / Evaluation clinique de l'occlusion de jeunes Sénégalais.

The dental occlusion is a basic phase of mastication moreover it is an everlasting concern for the dentist during therapeutic and prevention of dento-maxillo-facial disorders. Senegal is a country of recent dental practice and dental problems are frequent in it. We led this clinical assessment of occlusion on a sample of 30 young Senegalese people aged 18 to 35 years and we tried to evaluate the consequential effects on teeth and periodontal tissues with intent to use this study as pattern of prevalence evaluation of occlusion disorders. Taken at random in the consultation at the Institute of Odontology and Stomatology, these people have been selected by excluding any obvious cause of occlusal disorders. 76.67% of our sample are students and the average patient of the study is à 24 years man, wolof, student dwelling in Dakar. He has an avoid face, is in normocclusion or prognathia and presents a tooth affection which can be related to malocclusion and defective hygiene. 67% of examined teeth are in contact during maximal occlusion and 33% are in entire lack of posterior contact during protrusion meanwhile 73 to 80% present group function. In 70% of studied cases, the superficial periodontium is affected and 30% representing the deep periodontium, are quite safe. This word is a first attempt of prevalence evaluation. It has to be led in multicentric study and at a larger scale in order to have more exact sight of young Senegalese occlusal disorders.
