Tracking disease changes in mouth scarring

Doctors often see scarring inside the mouth that can turn into cancer over time. This scarring, called oral submucous fibrosis, starts small but can grow worse. Researchers wanted to know if a specific protein might predict when the disease gets more serious or turns cancerous. They looked at studies that checked for alpha-smooth muscle actin, a protein found in certain cells. These cells, called myofibroblasts, help heal wounds but can also make scarring worse. The review combined data from many studies to see if this protein could be a trustworthy sign of disease progression.The results suggest this protein might help spot patients at higher risk before symptoms get severe. However, the evidence isn't perfect. Some studies showed strong links while others didn't, making it hard to draw firm conclusions. More research is needed to confirm if this protein can reliably guide treatment choices.
