The regeneration of dental pulp and dentin is one of the most exciting research areas in modern dentistry. Especially in immature teeth with necrotic pulp and apical periodontitis, restoring tooth vitality remains a major challenge.

Oral infections such as periodontitis, peri implantitis, or wound healing complications after tooth extractions remain major challenges in dentistry. Commonly used antibiotics or systemic therapies often reach their limits: drug concentrations at the infection site are frequently insufficient, while side effects and resistance development pose additional risks. For this reason, locally active, bioactive materials are gaining increasing attention in research.

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]

Good dentures are becoming increasingly important as the population ages. Conventional materials for the base of dentures are often porous and thus susceptible to deformation or microbial colonization. To prevent this, chitosan is added to polymethyl methacrylate resin in the presented study.

Dental erosion is the demineralization of the hard tooth substance caused by acids. Particularly in industrialized countries this is an increasing problem due to changes in drinking and eating habits in recent decades. Additionally, the teeth surface is eroded by mechanical interaction like brushing. To substantially reharden demineralized enamel, the development of appropriate prophylaxis and therapy is important. HMC presents two studies that tested toothpaste and mouth rinses containing chitosan.
