Description
Jorge Miguel Santacruz-Monzon and colleagues test leaf extracts from the African tulip tree as a rinse for infected root canals, in a 2026 laboratory study. The target bacterium, Enterococcus faecalis, survives inside teeth and resists standard treatment, so plant-based alternatives interest dentists. Six extracts made with different solvents were screened for the lowest doses that stop or kill the bacterium, then compared in dishes against bleach solution.
The water-based extract failed, while the others halted the bacterium at low concentrations. Ethanol and acetone extracts matched the bleach in dish tests at high strength. In extracted human teeth carrying four-week-old bacterial films, the ethanol extract cut living bacteria far more than the bleach rinse did. Rich plant compounds such as flavonoids and tannins may explain the effect, the authors suggest.
