Self-Healing Materials - Future perspectives of dental care
- What will be role of material science in the future perspectives of dental materials/dentistry technology?
- How self-healing materials will bring changes medicine and dentistry technology?
- Can future self-healing material science will be able to replace current antimicrobial cleansing?
Self-healing functional materials
- Most widely used materials for dental restoration are amalgams composed of silver and mercury.  These amalgams are strong and long lasting, however there have been increasing concerns about their toxicity. In US dental amalgams are now classified as Class II medical device although FDA maintains that they are safe to use.  European Union, however, has discouraged the use of dental amalgams in children and pregnant women as a first choice.  Composite resins, compomers, and giomers are increasing in popularity not only due to their relatively non-toxic nature but also because they can be modified to possess antibacterial properties. However these alternative materials are less robust compared amalgams [3,4].
- Material science research of versatile, durable, non-toxic and with active ingredient materials is of increasing interest . Material science also has challenge of making the restoration materials with qualities that are pleasing to the aesthetics. 
- Materials with auto repair properties capable of fracture resistant and fracture self-healing are attractive for dental restoration as they can be durable. Durability of any dental restoration will certainly improve the quality of patients life. [5, 6, 7]
- There are several scientific articles reporting composite materials with antimicrobial properties. For instance, the use of non-leaching antibacterial composite material based on polymerization of methacryloyloxydodecylpyridinium bromide (MDPB).  Zhang et al have reported composite materials with mesoporous silica nanoparticles for slow release of antibaterial molecule chlorhexidine.  However, at present it cannot be concluded that these new materials can completely eliminate the need for antibacterial wash. Development of better composites with improved properties are of both scientific as well as commercial interest.
