In Vivo Evaluation of Magnesium Gel on Collagen Remodeling in Advanced Palatal Wound Healing
This study demonstrates that topical magnesium gel significantly accelerates palatal wound healing and enhances collagen remodeling in rats compared to untreated or plain gel controls, suggesting it as a promising therapeutic agent for oral surgery recovery.

When the body heals a cut, it does not simply stitch itself back together like a torn piece of fabric. Instead, it launches a complex, timed sequence of biological events. First, the area swells and sends in cells to clean up the damage. Then, a new layer of skin begins to grow over the wound, while underneath, a scaffolding of protein fibers called collagen is built to hold the tissue together. This scaffolding is the foundation of strength; if it is disorganized or too thin, the healed area remains weak or forms a visible scar. In the mouth, where the tissue is constantly moving and exposed to bacteria, this process is especially difficult. A wound on the roof of the mouth, often caused by dental work, can be painful and slow to heal, leaving patients uncomfortable and vulnerable to infection. Scientists have long searched for safe, simple materials that can guide this natural repair process, helping the body build a stronger, more organized structure faster than it could on its own.
One such material is magnesium, a mineral that acts as a vital helper for hundreds of chemical reactions inside every living cell. It is essential for producing energy and building new tissue. While researchers knew magnesium helped cells grow in test tubes, they did not fully understand how it would behave in a living animal trying to heal a deep wound. To find out, a team of scientists at Alexandria University in Egypt designed an experiment to see if a gel containing magnesium could speed up the healing of wounds on the roof of the mouth. They chose to study this in rats, whose healing patterns are well understood and closely resemble how human mouths heal. The researchers created a small, standardized hole in the roof of the mouth for each animal and then applied different treatments to see which one worked best.
The study involved thirty-six rats, divided into three groups to ensure a fair comparison. One group received no treatment at all, serving as a baseline to see how a wound heals naturally. A second group received a plain gel made from a common, safe substance called carboxymethyl cellulose, which acts as a soothing base but contains no medicine. The third group received the same gel, but this time it was loaded with magnesium. The researchers applied the gel twice a day to the wounds. They then watched the animals closely for two weeks, taking photographs and eventually examining the tissue under powerful microscopes to see exactly what was happening inside the healing skin.
The results showed a clear difference between the groups. By the seventh day, the rats treated with the magnesium gel looked significantly better than the others. Their wounds were smaller, and the new skin covering them appeared pink and healthy, whereas the untreated wounds were still red and inflamed. When the scientists looked at the tissue under a microscope, they found that the magnesium group had closed the gap between the edges of the wound much faster. The new skin cells were more organized and mature, forming a stronger barrier against the outside world. In contrast, the untreated group and the group with plain gel still had a noticeable gap and less organized tissue.
The story became even more compelling when the researchers examined the collagen, the protein fibers that give skin its strength. On the fourteenth day, all the wounds had closed, but the quality of the repair varied greatly. The rats treated with magnesium had built a much thicker and more densely packed layer of collagen fibers. Under the highest magnification, the fibers in the magnesium group appeared thicker and more neatly arranged, resembling a tightly woven fabric rather than a loose mesh. The cells responsible for building this material, called fibroblasts, had also finished their work more efficiently in the magnesium group, transitioning into a resting state that signaled the healing process was complete. In the other groups, the fibers were thinner and less organized, suggesting the tissue was still in the early stages of strengthening itself.
The researchers concluded that the magnesium gel did more than just keep the wound moist; it actively helped the body rebuild its internal structure. The magnesium appeared to encourage the skin cells to multiply and move into place faster, while simultaneously helping the collagen fibers grow thicker and align correctly. This led to a wound that not only closed sooner but also healed with a stronger, more organized foundation. While the study was conducted in rats and further research is needed to confirm these effects in humans, the findings suggest that a simple magnesium gel could be a powerful tool for improving recovery after oral surgery, turning a painful, slow process into a faster, more robust repair.
