Flavanones are flavonoids with anti-inflammatory, antioxidant, antimicrobial and blood-lipid-lowering properties. Naringin, naringenin and hesperidin are the most well-known flavanones, and they would be a beneficial approach of new therapies in dentistry. The present review evaluates the current evidence relating to the antibacterial activity of naringin and other flavanones toward microorganisms commonly responsible for oral pathology. We identified 11 articles reporting the minimum inhibitory concentration, minimum bactericidal concentration and zone of inhibition for flavanones. While studies on naringin and other flavanones have mainly investigated the effects on Enterococcus faecalis, this review revealed considerable evidence suggesting that flavanones are effective against all bacterial oral pathogens. However, concentrations of up to 1000 µg/mL may be required to combat Gram-negative bacteria involved in periodontal disease.
