“…The material substratum is an essential factor that contributes to the ability of a pathogen to adhere to and form biofilm on a surface (Brandao et al 2015;Fernandez-Delgado et al 2015). Aside from cellular properties and pathogen adhesion mechanisms, variations in surface roughness, hydrophobicity and chemical structure can impede or promote a pathogen's ability to attach and populate on that surface.…”

In the hospital environment, Acinetobacter baumannii is one of the most persistent and difficult to control opportunistic pathogens. The persistence of A. baumannii is due, in part, to its ability to colonize surfaces and form biofilms. This study demonstrates that A. baumannii can form biofilms on a variety of different surfaces and develops substantial biofilms on polycarbonate - a thermoplastic material that is often used in the construction of medical devices. The findings highlight the need to further study the in vitro compatibility of medical materials that could be colonized by A. baumannii and allow it to persist in hospital settings.

“…The differences between metal and ceramic brackets have been studied in multiple aspects comparing different characteristics between the two types 6. Regarding plaque accumulation, some studies have proved no significance between both brackets,7 while Brusca et al8 reported the metal brackets have less bacterial accumulation compared to ceramic brackets.…”

Aim To evaluate the degree of enamel demineralization of teeth bonded with ceramic and metal brackets. Materials and methods In this cross-sectional experimental in vitro study, 60 extracted human premolar teeth were selected according to the experimental criteria. They were divided into three groups; 20 premolar teeth in each group. Teeth in group 1 were bonded with “ceramic brackets”, and teeth in group 2 were bonded with “metal brackets”, while teeth in group 3 served as the “control group” without any brackets. Teeth in all groups were then immersed in demineralization media, de-bonded, sectioned into three parts (proximal 1, middle, and proximal 2), and evaluated to determine the level of enamel demineralization under a Scanning Electron Microscope. Results On tooth level, the results show that the control group has significantly less enamel demineralization compared to the other two experimental groups, with mean values of 145.3 µm and 192.7 µm, respectively ( P =0.000). The mean value of enamel demineralization in the metal group is 55.93 µm, compared to 72.55 µm in the ceramic group, which is significantly less ( P ≤0.05), while there is no difference between the control and metal group with regard to enamel demineralization. On section level, the control group has significantly less enamel demineralization in all three sections compared to the ceramic group, while a significant difference is found in one of the proximal sections when compared with the metal group. Moreover, the ceramic group has significantly higher enamel demineralization in the middle section compared to the metal group (73.54 µm, 46.5 µm, respectively) ( P =0.000), while there is no statistical significant difference between the two experimental groups in proximal sections. Conclusion In vitro, non-bonded teeth show least demineralization compared to the bonded teeth. Teeth bonded with ceramic brackets show significantly higher enamel demineralization compared to teeth bonded with metal brackets.

“…Other studies also reported that residue accumulation is commonly observed in the clinical scenario during orthodontic therapy with different types of devices (24)(25)(26)(27). In orthodontic patients, caries prevention represents a significant challenge (27) and requires clinical studies in order to prevent and control caries during orthodontic treatment.…”

Quantification of Streptococcus mutans in Different Types of Ligature Wires and Elastomeric Chains

This study aimed to test the hypothesis that Streptococcus mutans contamination levels differ according to the type of the orthodontic ligature. Thirteen patients were selected. Each quadrant was randomly subjected to one of the following ligature-use protocols: I) elastomeric chain, II) steel ligature crossed over the archwire, III) steel ligature crossed under the archwire, and IV) steel ligature in a figure-eight pattern under the archwire. After seven days, the devices were removed and the Streptococcus mutans colony-forming unit count per mg of biofilm weight was determined. Twelve specimens (n=3) were also processed for scanning electron microscopy analysis. ANOVA and Tukey-Kramer test were used for comparisons to assess S. mutans differences between groups at a 5% significance level. There was no statistical difference in detectable levels of S. mutans among the groups (p=0.294). Scanning electron microscopy results showed abundant biofilms and microbial contamination in all groups. In conclusion, S. mutans contamination levels are similar in the different orthodontic ligatures.
