“…P. acidifaciens, which is a Gram-positive anaerobic bacillus, is reported to be saccharolytic, producing large amounts of acetic and propionic acids [Downes and Wade, 2009]. Propionibacteria are increasingly reported to be present in deep dentin [Edwardsson, 1974;Hoshino, 1985;Munson et al, 2004;Chhour et al, 2005;Aas et al, 2008;Downes and Wade, 2009;Belda-Ferre et al, 2011] and root caries [Hashimoto et al, 2011]. Recently, Chhour et al [2005] reported that obligate anaerobes dominate carious dentin lesions.…”

“…Biofilm accumulation slows the diffusion of organic acids and restricts the access of pH-buffering saliva, subjecting the enamel to repeated and prolonged exposure to an acidic pH (pH Ͻ5.5) and thereby initiating the dental caries process (3,14). Left untreated, further demineralization of the enamel and extension of the lesion expose the underlying dentin, presenting collagen and other, additional substrates for bacterial colonization (15,16). Other oral tissues, such as the cementum, root, and periodontal ligament fibers, are also rich in collagen (17) and, if exposed to the oral environment, may be vulnerable to attachment and colonization by microbes equipped with collagen-binding adhesins (13,(18)(19)(20).…”

“…Nosotros hemos demostrado un rol protector contra la desmineralización inducida por Streptococcus mutans por parte de algunos ácidos grasos (28) . Las proteínas aportadas en forma exógena en la dieta pueden ser degradadas por flora microbiana proteolítica específica presente en el biofilm oral (29) . Nuestro grupo abordará el cómo la presencia de proteínas de la dieta puede condicionar un mayor riesgo de caries radiculares en pacientes diabéticos con una serie de experimentos relevantes para intentar esclarecer este tema.…”
