ABSTRACT

Le prothésiste dentaire est exposé à un risque élevé de transmission infectieuse par la manipulation des empreintes dentaires souillées par la salive et le sang. En effet, lors d'une prise d'empreinte au cabinet dentaire, le matériau entre en contact direct avec les mucosités et sérosités de la cavité buccale, abritant de nombreux germes. Ainsi la décontamination des empreintes, pour prévenir la contamination croisée. Cette étude a eu pour objectif d'évaluer les attitudes et pratiques des prothésistes dentaires dans la ville d'Abidjan, en matière de décontamination des empreintes. Il s'agit d'une étude transversale descriptive qui s'est déroulée sur une période de trois (03) mois. Elle a concerné 35 prothésistes dentaires exerçant tant dans les secteurs privés et publics. Plus de 97% des prothésistes dentaires interrogés, sont conscients de l'existence du risque infectieux liés aux empreintes dentaires. Aucune des empreintes reçues par les prothésistes, n'était accompagnée de fiche mentionnant son état de décontamination. 85,71% des prothésistes, affirment rincer systématiquement toutes les empreintes dès leur réception et près de 32% ne les décontaminent pas

ABSTRACT

Introduction : En prothèse fixée dento-portée, la préparation des dents supports est la soustraction des tissus dentaires coronaires ou corono-radiculaires, qui permet d'obtenir l'espace prothétique nécessaire à l'adaptation parfaite de l'ancrage prothétique. C'est un acte essentiel du plan de traitement que de nombreux praticiens appréhendent. Objectif : Ce travail vise à comparer les angles de convergence des parois mésio-distales (proximales) avec ceux des parois vestibulo-linguales des modèles positifs unitaires pour apprécier les difficultés inhérentes à leur préparation. Méthodes : Il s'agit d'une étude expérimentale qui a consisté à la mesure de l'angle de convergence des parois de 249 modèles positifs unitaires (MPU) à l'aide du logiciel d'acquisition et de traitement d'image du microscope digital PCE-MM 200 UV®. Les données recueillies ont été traitées et analysées à l'aide du logiciel SPSS version 20. Résultats : L'angle moyen d'inclinaison des parois vestibulo-linguales (30,95±15,32°) est statistiquement supérieur à celui des parois mésio-distales (21,82±10,89°) (p=0,000). Conclusion : La préparation des faces vestibulaires et linguales est plus difficile à réaliser que les faces mésiales et distales en raisons l'accès visuel indirect qui n'est pas toujours aisé et de la morphologie de ces faces. L'utilisation de techniques de préparation comme la pénétration contrôlée pourrait constituer un moyen efficace pour réduire de façon significative l'angle de convergence des faces vestibulaire et linguale et augmenter ainsi la valeur rétentive des préparations

ABSTRACT

BACKGROUND: The confection of a fixed prosthesis finds its indication in response to the patient's aesthetic and/or functional whose requirements are stronger in terms of satisfaction. This involves maintaining the stability of prosthetic reconstructions on a sufficiency long time. To achieve this, the preservation of periodontal health of the prosthetic abutments occupies a special choice. PURPOSE: The aim of this study was to evaluate the periodontal health of fixed prosthesis abutment. MATERIALS AND METHODS: Thirty-nine patients having fixed prosthesis in the mouth for more than one year participated in our study. Ultimately, 38 single crowns and 27 seven bridges based on 100 abutments have been recorded. After an interview, clinical and radiographic examination was performed. It was to assess the level of oral hygiene, the health of the superficial and deep periodontal abutment using OHIS index of Green and Vermilion, periodontal index of Russel and mobility index of Mühlemann. RESULTS: On the 100 abutments examined, gingivitis (14%), gingival recession (13%), bone osteolysis (29%) and mobility (5%) were recorded. In addition, about 60% of patients had inadequate oral hygiene and less than 30% of them had a regular prosthetic maintenance. CONCLUSION: From this study, it appears that complications affecting periodontal prosthetic abutments are essentially bone lysed (29%), gingivitis (14%) and gingival recessions (13%).

ABSTRACT

INTRODUCTION: Access to cervical margins allows the practitioner to record the entire cervical margin in order to provide a true copy to the technician. This requires a gingival displacement obtainable by different techniques. This study aimed to assess the implementation of gingival displacement methods prior to impression taking in fixed prosthodontics. MATERIALS AND METHODS: This is a descriptive and cross-sectional survey of sample of 71 dentists practising in Abidjan, Ivory Coast; which ran from October 2nd, 2010 to November 14th, 2010. A survey form was administered to dentists. The questionnaire was organised around the following headings: identification of dentists and practice of gingival displacement methods. The data processing done using software Epi Info 6 and Excel XP on Window XP, allowed calculation of frequencies, means and proportions and the establishment of connection between variables with the chi2 test. The significance level was set at p < 0.05. RESULTS: The results of the survey indicate that non-surgical methods of gingival displacement, including retraction cords and temporary crowns are those they use most frequently (76.4%) because the vast majority of practitioners (87.22%) believe the most traumatic to the periodontium are surgical methods. CONCLUSION: Our study showed that the gingival displacement methods are frequently carried out in daily practice, regardless of the topography of the abutment teeth and their number, but with a preference for non-surgical methods, particularly those using retraction cords and temporary crowns. The use of injectable gingival displacement paste is not harmful to the periodontal tissues, easy to use and have a very efficient haemostatic action. It should also be known and practiced.

ABSTRACT

The functional colopathies are frequent in digestive pathology and are particularly badly felt by African patients. The authors, after the determination of the masticatory efficiency score (classification of Verkindere) of 100 subjects affected by colopathies and diagnosed in the service of gastroenterology of Cocody University Hospital (Abidjan), attempt to determine the importance of the masticatory deficiency in functional colopathies. Among the toothless subjects with functional colopathies, the restoration of the masticatory efficiency by functional prosthetic rehabilitation constitutes an essential therapeutic act in the reduction of the symptoms of the functional colopathies and the improvement of the comfort of the patients. Patients' global care raises the interest of collaboration between odontologists and gastroenterologists for an efficient treatment.

ABSTRACT

One of the concerns of the dental surgeon in the realization of any operational act is the durability of this one. The mechanical resistance of the provisional prostheses contributes in a large part to the durability of those. The resins in general, have weak mechanical properties. The purpose of this study is to evaluate the resistance in inflection of temporary bridges reinforced with glass fibre. To remedy the weak mechanical properties of resins, we thought in this study, to reinforce them with glass fibres. For this purpose, we realized with two different resins, four groups of temporary bridges of 3 elements, including two groups reinforced fibreglass and the others not. Tests of inflection 3 points have been made on these bridges and resistance to fracture was analysed. The statistical tests showed a significant difference in four groups with better resistance for the reinforced bridges.

ABSTRACT

The objective of this work was to determinate the average value of the condylar slope of Black African subject and to set up its variation according to whether the localization of the hinge axis is real or arbitrary. With this intention, we made an axiographic study at 63 subjects presented complete natural teeth, with a normoclusion in class 1 of Angle. The results of this study reveal that the average value of the slope condylar is 44,28 degrees in arbitrary hinge axis and 45,7 degrees in hinge axis real; and this difference is not statistically significant. The graphic recording of condylar displacement by the "Quick-Axis" is thus possible without risk of error in the layout and the reproduction of the mandible movements which is of a great interest for the general practitioner taking into account the simplicity of handling of the FAG system.

ABSTRACT

In the presence of anterior unitary tooth loss, the therapeutical arsenal of the practitioner remains the implant solution. But, at the young patients who have not completed their growth, it's necessary to pass by a transitional stage. The bonded bridges reinforced by a polyethylene fibbers splint such as Ribbond THM constitute an alternative of choice to solve the aesthetic damage in the short and medium term while waiting for the prosthesis with implant. It's a similar case that is reported through this article.

ABSTRACT

Studies on the dental health in Ivory Coast showed that the specific needs in prosthesis are numerous. Are there covered? What are the rates of the prosthetic consumption? It is to this question that the authors of the present work wanted brought a beginning of answer through a pilot prospective survey on the prosthetic demand to the service of prosthesis of the CCTOS of Abidjan. This survey was about 150 patients of all sex and all age come specifically for prosthetic rehabilitation, during the active period of February to April 1994. It takes out again of this survey this following results: from a general epidemiological point of view, the women are more numerous than the men, with an access frequency of 56%. Most topics are young, with an age between 20 and 30 years. The "social" rates that convenient the CCTOS attract the patients whose economic income is little important gladly or that are deprived of a health insurance. The prosthetic antecedents show that more than 65% of the topics never carried mainly a prosthesis for lack information or for lace money. Among the topics that already underwent a prosthetic treatment, prosthesis associate partial resin is the more frequently recovered in spite of an interesting rate of fixed prosthesis (37% of carriers). The clinical data reveal that aesthetic remains the main motive of the consultation, with 58% of demands and the prosthesis associate resin is in more of 70% of the cases the chosen therapeutic option.

ABSTRACT

The research of the predominant occlusal function during mandibular movements of laterality at the topic African melanoderme, drove authors of this survey to: select 52 healthy topics (11 women and 41 men), aged of 22 to 33 years old observe and note at every topic the presence and the nature of contacts or their possible absence of the working side during the movement of deduction. Observations done as well directly in mouth, that on models put in semi-adaptable articulators, permitted to note that the function of posterior group is more the recovered so much at women that at men, at the young adults and at adults.

ABSTRACT

The class A alginates present very good properties of dimensional precision and reproduction of details, comparable to those of the reversible hydrocolloïdes and certain elastomeres used for the realization of secondary prints of precision in fixed prosthesis and in removable prosthesis. Besides, their application is easier and they are costless. The valorization of these print materials could certainly contribute to reduce the cost of comes back of prostheses in countries under developed where the weak power economic populations constitute a brake to the access to cares of health. To exploit qualities of these print biomaterials well, it agrees to manage correctly the parameters of their application. To this effect, the present survey puts in evidence that the maximum delay of stream that guarantees the good dimensional stability of these class A alginates is of 45 minutes in the hot and humid climatic tropical country conditions.
