“…As cited by Shen et al and Bignozzi et al, they reported scanning electron microscopy observations revealed various patterns of bacterial coaggregation in RC lesions. Especially in cases of gingival recession, the root surface becomes more exposed, increasing the likelihood of developing RC . Synergistic growth was observed in cocultures of L. acidophilus with S. mutans and A. israeli as well as L. acidophilus , producing greater acidogenic and cariogenic effects on the root surface.…”

“…When root surfaces are exposed to the oral cavity, caries can initiate and progress more rapidly on root surfaces than on enamel surfaces [Ogaard et al, 1988;Keltjens et al, 1993;Kidd and Fejerskov, 2004;Bignozzi et al, 2014;Wierichs and Meyer-Lueckel, 2015]. Root surface caries is a biochemical process initiated by the demineralization, which in turn exposes the organic materials to degradation [Nyvad and Fejerskov, 1990;Kleter et al, 1994].…”

“…Both enamel and dentin/root caries are mainly initiated by the demineralization of the tooth surface through bacterial acid production from sugar [Deng and ten Cate, 2004;Kidd and Fejerskov, 2004;Selwitz et al, 2007;Featherstone, 2008;González-Cabezas, 2010;Bignozzi et al, 2014]. Therefore, it is necessary to evaluate tooth solubility at the tooth/bacteria interface, where the pH is gradually decreased by bacterial sugar metabolism and the solubility of the tooth surface can be modified by changes in pH and/or mineral concentration at the interface.…”

Evaluating the physiochemical processes at the tooth surface/bacteria interface is important for elucidating the etiology of dental caries. This study aimed to compare the mineral solubility and protein degradation of coronal enamel (CE) and root dentin (RD), and investigate the involvement of dissolved components in bacteria-induced pH changes using a model of tooth/bacteria interface. An experimental apparatus forming a well was made of polymethyl methacrylate, and a bovine tooth (CE or RD) specimen was fixed at the bottom of the well. A miniature pH electrode was placed on the tooth, and Streptococcus mutans NCTC 10449 cells, grown in 0.5% glucose-containing complex medium, were packed into the well. The pH at the tooth/S. mutans interface was monitored continuously for 120 min after the addition of 0.5% glucose at 37°C. S. mutans cells were recovered from the wells, and the amounts of lactate and calcium were measured using a portable lactate meter and a fluorescent dye, respectively. Proteolytic activity was also evaluated fluorometrically. The pH of the RD/S. mutans interface was significantly higher than that of the CE/S. mutans interface (30 min: 6.37 ± 0.12 vs. 6.18 ± 0.11, 60 min: 6.08 ± 0.14 vs. 5.66 ± 0.27, 90 min: 5.49 ± 0.24 vs. 5.14 ± 0.22, p < 0.05). Greater amounts of calcium were dissolved from RD (3.19 ± 0.74 µg/mL) than from CE (1.84 ± 0.68 µg/mL; p < 0.05), while similar amounts of lactate were produced. Proteolytic activity was not detected at any of the interfaces. These results indicate that RD is more soluble to bacteria-induced acidification than CE. This method can contribute to the evaluation and development of caries-preventive materials.

“…In such a patient, there may be a “food trap” (build-up of food particles and dense plaque between teeth) adjacent to a wide and tight interproximal contact—in addition to some gingival recession between these teeth. If ignored over time, interproximal tooth decay could easily develop in this area which could even lead to tooth loss 8 . Ideally, a person would both floss and use an appropriately-sized proxy brush in this area.…”

In Defense of Flossing: Can We Agree It's Premature to Claim Flossing is Ineffective to Prevent Dental Caries?

Current evidence pertaining to the effectiveness of flossing and caries prevention is potentially being misinterpreted by health oversight bodies, which may have significant implications for current and future public flossing guidelines. We identify and discuss several methodological deficiencies including the lack of validated measures of flossing skill, over-reliance on self-reported flossing behavior and the lack of current guidelines on how to interpret and apply evidence-based findings to specific clinical scenarios that are present in the studies of flossing effectiveness included in the Cochran Review. As such, we argue that it is premature for health oversight bodies to conclude that flossing is ineffective in the prevention of dental caries. Our research group, which is funded by the National Institutes of Health, is developing valid and reliable provider-observed measure of tooth brushing and flossing skill that may help promote higher quality flossing evidence in the future.
