Biofilm is a group of cells sticking together on a surface, embedded within a matrix of exopolysaccharides protecting them from antibiotics. Over 60% of microbial infections are caused by biofilms. The antimicrobial resistance increase of these communities involve several mechanisms, including: inactivation of antibiotics through extracellular polymers, decline of the growth rate by nutrient limitation and phenotypic changes in the bacterial cells, as a result of the resistant gene acquisition within the biofilm. Prognosis for treatment and eradication of biofilms is not the best one. The development of new medicines becomes necessary and urgent to counter biofilm related infections. This post shows the case of a 44 year old woman who goes to see the doctor for pain in 12, particularly upon vertical percussion. Such episodes are caused by under extended endodontics of 12 and in the extraradicular filling material of ducts. After the x-ray evaluation and appropriate application of the treatment plan, spherical shaped bacteria were detected within the biofilm, which caused the patient’s infection.
