Nanocomposites with antioxidant properties are gaining increasing importance in biomedical and particularly dental research. These materials combine conventional substances with nano-particles, aiming to enhance mechanical, chemical, or biological performance. [1]

Dental, bacterial diseases such as periodontitis can lead to tooth and bone loss. In the study presented here, chitosan, gelatine and Scutellariae baicalensis radix were combined to form a hydrogel to produce an anti-inflammatory implant using 3D bioprinting.

The development of a strong bond between implant surface and the surrounding bone substance, called osseointegration is important for successful integration of a dental implant. The coating of dental implants with chitosan is a promising approach to enable an accelerated and improved integration. In the following, we present two publications about chitosan-based coatings for dental implants.

166 articles about chitosan were published in May 2015. In the rank of nations scientists from China gained with 39 publications the leading position, followed by India (16), the US (12) and Italy (11). The research priorities focused on nanoparticles, evaluation studies and pharmaceutical preparations.

After dropping in the previous months, the publication number of chitosan articles slightly increased in July. Overall 76 articles were published in this field. In July 2010 83 articles were published, in comparison to this year it is only a small difference.
