Structural Organization of Dental Biofilm Formed in situ in the Presence of Suc...
Rezende,Gabriela; Arthur,Rodrigo Alex; Lamers,Marcelo Lazzaron; Hashizume,Lina NaomiAbstract Maltodextrins, derived from corn starch, have been added to industrialized food combined with sucrose. However it is not clear the diffusion properties of the dental biofilm matrix and the tridimensional structure of multispecies biofilms formed in the presence of these carbohydrates. Therefore, the aim of study was to investigate by confocal laser scanning microscopy (CLSM) the structural organization...
Role of Candida albicans on enamel demineralization and on acidogenic potential...
Eidt,Gustavo; Andrade,Caroline Gomes de; Negrini,Thais de Cássia; Arthur,Rodrigo AlexAbstract There is growing evidence that C. albicans is associated with dental caries, but its role on caries development needs to be better clarified. Objective: To evaluate at the hard tissue level the effect of C. albicans on the cariogenic potential of S. mutans biofilms focusing on the mineral profile of induced carious lesions. This study also aimed to evaluate the effect of C. albicans on the acidogenic p...
Recolonization of Mutans Streptococci after Application of Chlorhexidine Gel
Vale,Glauber Campos; Cury,Altair Antoninha Del Bel; Arthur,Rodrigo Alex; Cury,Jaime Aparecido; Tabchoury,Cínthia Pereira MachadoStreptococcus mutans is specifically suppressed by intensive treatment with chlorhexidine gel, but the time for recolonization and the effect on other oral bacteria are not totally clear. In this study, recolonization of mutans streptococci was evaluated in nine healthy adult volunteers, who were highly colonized with this microorganism. Stimulated saliva was collected before (baseline) and at 1, 7, 14, 21 and ...
Genotypic and phenotypic analysis of S. mutans isolated from dental biofilms fo...
Arthur,Rodrigo Alex; Cury,Altair Antoninha Del Bel; Graner,Renata Oliveira Mattos; Rosalen,Pedro Luiz; Vale,Gláuber Campos; Leme,Adriana Franco PaesThe oral cavity harbors several Streptococcus mutans genotypes, which could present distinct virulence properties. However, little is known about the diversity and virulence traits of S. mutans genotypes isolated in vivo under controlled conditions of high cariogenic challenge. This study evaluated the genotypic diversity of S. mutans isolated from dental biofilms formed in vivo under sucrose exposure, as well ...
Evaluation of genotypic diversity of Streptococcus mutans using distinct arbitr...
Tabchoury,Cínthia Pereira Machado; Sousa,Maria Clara K.; Arthur,Rodrigo Alex; Mattos-Graner,Renata Oliveira; Del Bel Cury,Altair AntoninhaStreptococcus mutans has been considered one of the main etiological agents of dental caries and the genotypic diversity rather than its salivary counts may be considered as a virulence factor of this bacterium. For genotyping with polymerase chain reaction (PCR) with arbitrary primers, several primers have been used in order to improve complexity and specificity of amplicon patterns. Thus, the aim of this stud...
Genotypic diversity of S. mutans in dental biofilm formed in situ under sugar s...
Arthur,Rodrigo Alex; Tabchoury,Cínthia Pereira Machado; Mattos-Graner,Renata de Oliveira; Del Bel Cury,Altair A.; Leme,Adriana Franco PaesIn situ dental biofilm composition under sugar exposure is well known, but sugar effect on the genotypic diversity of S. mutans in dental biofilm has not been explored. This study evaluated S. mutans genotypic diversity in dental biofilm formed in situ under frequent exposure to sucrose and its monosaccharide constituents (glucose and fructose). Saliva of 7 volunteers was collected for isolation of S. mutans an...
