“…4 Adhesion of bacteria to rough surfaces in the oral cavity is mediated by different mechanisms, involving the type of the bacterial species and the surface itself. 29 The results of the present study refuted the first hypothesis of the study and showed that the type of the restorative material signifi cantly affected the surface hardness, and giomer samples exhibited more SR. In the present study, a profi lometer was used to determine SR, which is an accurate and appropriate technique.…”

“…Bleaching might also affect the chemical composition of the surface enamel and restorative materials, changing the adhesion process. 29 Bleaching might result in a decrease in the adhesion of salivary proteins on the surface of bleached materials through factors containing peroxide, and it appears it might affect the adhesion of cariogenic bacteria, such as S. mutans and S. sobrinus. 36 Gurgan et al 42 reported an antibacterial effect for 10% carbamide peroxide, consistent with the results of the present study.…”

Introduction: Adhesion of bacteria, especially Streptococcus mutans (S. mutans) , to the surface of tooth restorations is a factor in the etiology of secondary caries. Given the ever-increasing popularity of bleaching procedures, the aim of the present study was to evaluate adhesion of S. mutans and surface roughness (SR) of microhybrid composite resin and giomer subsequent to the application of 15% carbamide peroxide.

“…The production of glucans promotes accumulation of S. mutans and strong adherence to solid surfaces 23,24) . In the present study, the water-insoluble glucans must have protected the formed biofilms even after vigorous shaking 25,26) . Perhaps, the current condition for FAAO incorporation into coating materials is not directly applicable for clinical applications.…”

The purpose of this study was to evaluate the inhibition of biofilm formation on newly developed coating materials with self-cleaning properties. A series of experimental coating materials containing fluoroalkylated acrylic acid oligomer (FAAO) were applied to resin composite substrates. The surfaces of the coating materials were analyzed by X-ray photoelectron spectroscopy (XPS) and contact angle measurement. Biofilm formation on the surface was assessed using Streptococcus mutans biofilms inside an oral simulator in vitro. The results indicated that an increase in the concentration of FAAO in the coating materials enhanced surface hydrophilicity and oil-repellency. Biofilm assays demonstrated that the amount of biofilm retained on the coating materials gradually decreased when the concentration of FAAO increased in the materials. It was concluded that the coating materials incorporated with FAAO possessed self-cleaning properties and displayed signs of inhibiting biofilm formation on their surfaces.

“…After corrosion, the rough surfaces increased the bacterial adhesion [34]. Previous research [35] measuring the surface contact angles on metal surfaces indicated that acid-treated surfaces exhibit increased contact angles and more hydrophobicity with increasing surface roughness.…”

Corrosion of dental alloys is a major concern in dental restorations. Streptococcus mutans reduces the pH in oral cavity and induces demineralization of the enamel as well as corrosion of restorative dental materials. The rough surfaces of dental alloys induced by corrosion enhance the subsequent accumulation of plaque. In this study, the corrosion process of nickel-chromium (Ni-Cr) and cobalt-chromium (Co-Cr) alloys in a nutrient-rich medium containing S. mutans was studied using inductively coupled plasma atomic emission spectrometry (ICP-AES), X-ray photoelectron spectroscopy (XPS) and electrochemical corrosion test. Our results showed that the release of Ni and Co ions increased, particularly after incubation for 3 days. The electrochemical corrosion results showed a significant decrease in the corrosion resistance (Rp) value after the alloys were immersed in the media containing S. mutans for 3 days. Correspondingly, XPS revealed a reduction in the relative dominance of Ni, Co, and Cr in the surface oxides after the alloys were immersed in the S. mutans culture. After removal of the biofilm, the pre-corroded alloys were re-incubated in S. mutans medium, and the expressions of genes associated with the adhesion and acidogenesis of S. mutans, including gtfBCD, gbpB, fif and ldh, were evaluated by detecting the mRNA levels using real-time reverse transcription polymerase chain reaction (RT-PCR). We found that the gtfBCD, gbpB, ftf and Idh expression of S. mutans were noticeably increased after incubation with pre-corroded alloys for 24 h. This study demonstrated that S. mutans enhanced the corrosion behavior of the dental alloys, on the other hand, the presence of corroded alloy surfaces up-regulated the virulent gene expression in S. mutans. Compared with smooth surfaces, the rough corroded surfaces of dental alloys accelerated the bacteria-adhesion and corrosion process by changing the virulence gene expression of S. mutans.
