Researchers at the University of Nottingham in the UK have developed a groundbreaking protein-based gel that leverages calcium and phosphate ions, naturally abundant in human saliva, to repair and regenerate damaged tooth enamel.
This innovation, detailed in a study published in Nature Communications, represents a potential shift away from traditional "drill and fill" dentistry toward true enamel restoration.
The gel mimics the natural proteins that guide enamel formation during infancy. When applied to teeth, it forms a thin, robust layer that seeps into cracks and eroded areas.
Acting as a scaffold, it attracts and organizes calcium and phosphate from saliva (or even donated saliva samples), promoting "epitaxial mineralization"—a process where new enamel crystals grow in perfect alignment with the existing tooth structure, restoring its hardness and architecture.
Lab tests showed the regenerated enamel withstands real-world stresses like brushing, chewing, and acidic exposure (e.g., soda) as well as—or better than—natural enamel. It remained intact for weeks in simulated oral environments.

Energy Over Time
The Rhythm of Fulfillment
by Dr. Tony Leachon
At my age, I no longer race against the clock—I rise to meet the dawn with energy.
A cup of coffee, a half-hour on the treadmill, light weights to keep bones strong, and a breakfast of simple nourishment—these are not chores, but rituals of renewal. They remind me that true productivity is not about racing against time, but about fueling the body, mind, and spirit.
Hospital work is demanding, and the rigors of service can easily drain strength. Yet I’ve learned that self-care is not selfish—it is duty. For when I care for myself, I extend that love to my patients, to my family, and to others who depend on me.
As Tony Schwartz wrote in Harvard Business Review, time is finite, but energy is expandable. When we manage energy—physical, emotional, mental, and spiritual—we unlock a deeper rhythm of fulfillment.
And in work, satisfaction is found not in hours logged, but in moments that restore energy:
• An inbox cleared to zero brings mental clarity.
• A task finished ahead of deadline brings emotional relief.
• A canceled meeting returns precious space.
• Solving a problem no one else could brings confidence.
• Closing the laptop with nothing pending brings peace.
• A calm, interruption-free day sustains focus.
• Clear feedback validates effort.
• Automating a task frees mental bandwidth.
• Logging off on time restores balance.
• Being appreciated uplifts the spirit.
These are not just tasks completed—they are energy renewed, purpose reaffirmed, and joy rediscovered.
True wealth is not measured in hours, but in the energy we invest in others.
Every step on the treadmill, every mindful meal, every pause for reflection is not just for me—it redounds to the people I serve. Discipline sustains the body, purpose fuels the spirit, and love carries both forward.
Success is not measured by the hours we spend, but by the energy we invest.
When energy flows outward—into compassion, service, and joy—it multiplies, leaving behind a legacy that time alone could never hold.
