Scientists in Brazil have engineered a novel biomaterial that combines jackfruit latex, pomegranate peel extract, and a common heart drug to repair tissue destroyed by periodontitis, one of the most damaging forms of gum disease.
The breakthrough comes from researchers at the Pontifical Catholic University of São Paulo, who designed the material to attack periodontitis from multiple angles at once. The chronic inflammatory disease destroys the structures anchoring teeth to bone, ultimately leading to tooth loss if left untreated.
Existing treatments control infection and inflammation but rarely regenerate the lost tissue. Surgical approaches like bone grafting produce unpredictable results. The team sought a different path by exploring how natural materials could be combined with targeted drug delivery.
Jackfruit latex emerged as a key ingredient because of its stickiness. "The adhesive properties would allow the material to stay longer at the disease site, releasing therapeutic compounds directly where needed and potentially reducing the need for systemic antibiotics," explains Professor Eliana Aparecida de Rezende Duek, who led the research.
The pomegranate peel brings antimicrobial power to the formula. The third component, simvastatin, is a statin medication widely used to lower cholesterol, but it also triggers bone formation and reduces inflammation. In this form, delivering it locally avoids a key problem with oral doses: the liver traps most of the drug, so patients need high doses that increase the risk of muscle damage.
The researchers manually harvested latex from fresh jackfruit and carefully purified it before incorporating the pomegranate extract and simvastatin into a gel-like matrix. Laboratory testing used human stem cells to evaluate whether the material could trigger osteoinduction, the biological process that transforms cells into bone-forming tissue.
All three doses of simvastatin tested (0.3%, 0.6%, and 1.2%) proved both safe and effective at kickstarting bone formation within two weeks, with even stronger results by three weeks. The gel structure remained stable across all concentrations.
"The results were very encouraging," Duek says. "This material has received almost no scientific attention for medical use until now, which makes the potential especially exciting."
She cautioned that clinical use remains years away. The team is launching additional studies to thoroughly evaluate safety and effectiveness before the technology moves toward human trials.
Author Jessica Williams: "A sticky fruit gel that could save teeth is exactly the kind of unglamorous innovation that changes dental medicine, if it holds up in the next round of testing."
