There is a great diversity of restorative materials and techniques for deciduous molars with significant coronal destruction, including resin composite restorations and biologic restorations (portions of natural teeth). By using 4 evaluation methods, this study aimed at longitudinally evaluating the effectiveness of restorations in the deciduous molars of a patient having high caries activity, ...

conclusions data reported here indicated that there is no specific genetic combination beyond the quantity of biofilm biomass in s. epidermidis. biofilm biomass seemed to be controlled by rnaiii expression level. further interest should be directed to biofilm dispersal since it seems that the key difference in biofilm biomass ability of s. epidermidis strains relates to factors regulating this ...

Abstract Dimension stone is natural rock prepared for building use. It rapidly colonised by microorganisms that cause discoloration (mainly cyanobacteria, algae and fungi) structural damage. Microbial mobilisation of ions leads to new superficial or internal deposits, weakening the structure. Cyanobacteria fungi may penetrate, filling pores creating spaces. Lichens, fungus/phototroph associatio...

Periodontitis is a chronic inflammatory condition initiated by the accumulation of bacterial biofilm. It highly prevalent and when left untreated can lead to tooth loss. The presence biofilm essential for initiation response but not sole initiator. Currently it unknown which mechanisms drive dysbiosis leading dysregulation response. Other players in this equation include environmental, systemic...

introduction: although bacteria producing biofilm are more resistance to antimicrobial agents, biofilm formation can stimulated by sub-minimal inhibitory concentrations (sub-mics) of some antimicrobial agents. therefore, we designed present study to investigate the  in vitro efficacy of several antibiotics (including ceftazidime, piperacillin, ticarcillin, carbenicillin, aztreonam, meropenem, g...
