[The complexion and color of teeth in a Black African population. Apropos of a sample of 240 subjects].

From a sample divides in five groups of different skin colours, the authors determine, by the visual method, the shade of incisives, canines and first premolars. This study allows to confirm the harmony between the anterior teeth among African melanoderme subjects. Then, it underlines a possible relation between the skin colour and the teeth's shade. In fact, the shade of the teeth seems to evolve in the opposite direction of the colour of the skin in the experimental sample.

[Artifacts induced by dental reconstruction materials: the case of titanium].

MRI is becoming an important tool of examination of the head and neck. However, certain dental alloys cause artifacts characterized by a loss of signal surrounded by bright line and sometimes distortions. In our work, we studied artifacts caused by Titanium, metallic biomaterial used for oral implantology. Therefore, 2 experimental were investigated in a 1.5 T MR unit, with 2 sequences commonly used (SE, GRE). The investigation showed minor artefacts, without distortions. In order to minimize these "ghost images", the Titanium and its alloys should be an alternative.

[Toward a more resistant resin, more economical and better suited to conditions in developing countries].

The breakage of prosthesis constructed in polymethacrylate resin is a reality in daily practice. Several solutions have been proposed to overcome this problem. Thus, the reinforcement of resin with carbon fibre improved greatly the mechanical properties, notably the fatigue strength. The technique of elaboration of such prosthesis proposed in this study has little impact on aesthetic as well as on the final cost. This proposition could be a relevant solution for third world countries opposite to economical and technological problems generated by cast metallic framework.

[Occlusal-articular impact of late consultation].

Partial toothlessness, lately or wrongfully compensated, are at the origin of prosthetics problems often difficult to solve. We shall explain the importance of dental grooves in the prosthetics process, through different cases of temporomandibular dysfunction.

[Removable prosthesis: masticatory efficiency].

The late consultation in odontology often leads to tooth extraction. This negligence, in a long term, will cause complete toothlessness. This state of invalidity will be compensated by prosthesis. The removable prosthesis is often indicated because of the cost price. It is the result of a successful therapeutics, only if it fits aesthetically and functionally, within a chewing efficiency. In a first part, we will define masticatory efficiency, as different from masticatory capacity and capability. Then, in a second part, through some experimentation, we will show how fundamental research can guide the practitioner in his prosthetics choices and assessments.

[Implant-supported complete denture].

Total toothlessness too lately or wrongfully compensated remain at the origin of prosthetic problems often difficult to solve through conventional prosthesis. We shall explain the importance of implantology in this type of medication. After presenting the different solutions brought by the importance in the rehabilitation of toothless maxilla we shall describe the process of making a supra-implanted lower maxilla prosthesis. Applications and non-applications will be directed; then the different elements and stages of the making of this type of this mucous-membrane-held prosthesis will be described. The retention is assured by two hooks tightly clasped onto a crossbar supported by the implants.
