Tooth blood test could tell if a root canal is really needed

This study looks at whether substances in the blood from a tooth's pulp can help dentists tell the difference between reversible pulpitis (a mild inflammation that can heal) and irreversible pulpitis (severe damage needing a root canal). Researchers will collect a small sample of pulp blood during routine dental treatment from 75 healthy people aged 12–35. They will measure levels of various inflammatory and other biomarkers and compare them across healthy teeth, reversible pulpitis, and irreversible pulpitis. The goal is to find biomarkers that improve diagnostic accuracy and guide treatment decisions.
