Background. The biological, chemical, behavioral and physical sciences provide the fuel for innovation, discovery and technology that continuously improves the quality of the human condition. Computer power derived from the dramatic breakthroughs of the digital revolution has made extraordinary computational capacity available for diagnostic imaging, bioinformatics (the science of information) and numerous aspects of how we practice dentistry in the 21st century.

Overview. The biological revolution was initiated by the identification of the structure for DNA in 1953, a discovery that continues to catalyze improvements in patient care through new and better diagnostics, treatments and biomaterials. Humanity’s most basic and recognizable characteristics—including the face—are now better understood through the elucidation of our genome and proteome, the genes and proteins they encode. Health care providers are beginning to use personalized medicine that is based on a person’s genetic makeup and predispositions to disease development.

Conclusions. Advances in the fields of genetics, developmental and stem cell biology, and many other disciplines continue to fuel innovative research findings that form the basis for new diagnostic tests, therapeutic interventions and procedures that improve the quality of life for patients. Scientists are on the threshold of applying knowledge in stem cell biology to regenerative medicine and dentistry, heralding an era when clinicians can consider using biological engineering to replace tissues and organs lost to disease or trauma.
