Evaluation of bacteria-induced enamel demineralization using optical profilometry

Abstract: Objectives Streptococcus mutans is considered a major causative of tooth decay due to it’s ability to rapidly metabolize carbohydrates such as sucrose. One prominent excreted end product of sucrose metabolism is lactic acid. Lactic acid causes a decrease in the pH of the oral environment with subsequent demineralization of the tooth enamel. Biologically relevant bacteria-induced enamel demineralization was studied. Methods Optical profiling was used to measure tooth enamel decay with vertical resolution unde… Show more

“…4). From previous studies, it is known that polished sound enamel (of bovine origin) displayed an eightfold increase in roughness average due to demineralization after 72 h of exposure to Streptococcus mutans colonization [36]. Thus, given an established biofilm, further demineralization (and, consequently, lesion progress) of exposed enamel of infiltrated subsurface lesions would seem most likely.…”

“…5 The most important causes of enamel erosion are the dissolution of acids derived from Streptococcus mutans as well as dietary, occupational and intrinsic sources. 6,7 The usefulness of fluoride-releasing materials for enamel remineralization has been demonstrated in various models. 8,9 Fluoride catalyses the diffusion of calcium and phosphate into the tooth surface, which in turn remineralizes the crystalline structures in dental cavities.…”

“…The technique uses light that is split, directed, and reflected from an object and a reference surface, and generates fringes from the interference of these two beams (Schmit et al, 2008). Characteristic interference patterns are translated into topographical images by computer software (Cross et al, 2009). It allows the nondestructive, noncontact, fast, and wide‐field measurements with vertical resolution down to a fraction of a nanometer (Schmit et al, 2008).…”
