[Evaluation of crown-root restorations in non-vital teeth. Survey of dentists in the city of Abidjan].

Coronal-radicular restoration is the coronal reconstruction of an endodontically treated tooth, with a support on and in the root. The objective of this study is to assess the importance of the carried coronal-radicular restorations in the dental practice in Abidjan. It is about a prospective survey of 100 dental surgeons practicing in the city of Abidjan, pulled at random.

Nano-odontology: nanostructured assemblies for endodontic regeneration.

The vitality of the pulp is so fundamental to the functional life of the tooth that new strategies are required to avoid the removal of the whole pulp following irreversible pulpitis and to regenerate the lost endodontic tissues. Nano-odontology would provide suitable solutions for pulp tissue conservative and regenerative approaches. In our group, we have shown that when covalently coupled to Poly-Glutamic Acid (PGA) the incorporation of an anti-inflammatory hormone (melanocortin, a-MSH) into the multilayered films Poly-L-Lysine (PLL)/PGA increases the anti-inflammatory reaction of pulp fibroblasts and macrophages stimulated by LPS (Lipo-Polysaccharides).

[Survey of general dental practitioners in Abidjan on the use of the operatory field in dentistry].
