Easier endodontics for GDPs

Temporization for endodontics.

Teeth undergoing root-canal therapy are susceptible to microbial contamination from oral fluids both during and after treatment. With the exception of single-visit treatment, the use of a temporary restoration is mandatory. This review aims to provide an overview of the materials and techniques used for short- and long-term restorations during and immediately after endodontic treatment, and to ...

Biomimetic microenvironments for regenerative endodontics

Regenerative endodontics has been proposed to replace damaged and underdeveloped tooth structures with normal pulp-dentin tissue by providing a natural extracellular matrix (ECM) mimicking environment; stem cells, signaling molecules, and scaffolds. In addition, clinical success of the regenerative endodontic treatments can be evidenced by absence of signs and symptoms; no bony pathology, a dis...

Making Life Easier for Firefighters

Being a firefighter is a tough job, especially when tight city budgets do not allow enough firefighters to be on duty when a fire starts. This is formalized in the Firefighter problem, which aims to save as many vertices of a graph as possible from a fire that starts in a vertex and spreads through the graph. In every time step, a single additional firefighter may be placed on a vertex, and the...

Morphing Software for Easier Evolution

One of the biggest challenges in software evolution is maintaining the relationships between existing program structures. Changing a program component (e.g., a class, interface, or method) typically requires changes in multiple other components whose structure or meaning depend on the changed one. The root cause of the problem is redundancy due to lack of expressiveness in programming languages...
