Concentration-dependent inhibition of Streptococcus mutans metabolic activity by purified Croton lechleri latex (sangre de grado) in vitro
Background. Chlorhexidine is the reference chemical antiplaque agent, but its adverse effects motivate the search for plant-derived alternatives. The proanthocyanidin-rich latex of Croton lechleri (sangre de grado) is a candidate, yet quantitative concentration-response data against Streptococcus mutans are scarce. Methods. In this exploratory in vitro study, ethanol-purified C. lechleri latex…
