“…By increasing the incubation time, adherence of S mutans has been shown to increase. 17 However, for this factor too the opposite has been shown, with a decrease in the affinity of bacteria to the bracket surfaces over time. 6 In the presence of S sanguis, the adhesion of S mutans to brackets was significantly lower (P Ͻ .0001) than the adhesion of the bacteria alone.…”

Objective: To examine the difference in the adhesion of Streptococcus mutans to three different types of orthodontic brackets and the effect of the presence of an early salivary pellicle and Streptococcus sanguis on adhesion. Materials and Methods: Three adhesion experiments were performed using stainless steel, ceramic, and plastic orthodontic brackets. In the first experiment a clinical strain of S mutans adhered to the three different types of brackets (n ϭ 6 for each). For the second, the brackets were treated with saliva before adhesion of S mutans (n ϭ 6 per type of bracket). Finally, the third experiment concerned saliva coated brackets (n ϭ 6 per type of bracket), but before S mutans, S sanguis bacteria were allowed to adhere. The bacteria were always allowed to adhere for 90 minutes in all the experiments. Adhesion was quantitated by a microbial culture technique by treating the brackets with adhering bacteria with trypsin and enumerating the total viable counts of bacteria recovered after cultivation. Results: There were consistently no differences in the adherence to stainless steel, ceramic, or plastic brackets. The presence of an early salivary pellicle and S sanguis reduced the number of adhering S mutans to all three types of brackets. Conclusions: Adhesion of bacteria to orthodontic brackets depends on several factors. The presence of a salivary pellicle and other bacterial species seem to have a significant effect on the adhesion of S mutans, reducing their numbers and further limiting any differences between types of brackets.

“…Although several studies have investigated bacterial adhesion to prefabricated brackets, relatively little research has been performed on the raw materials. [14][15][16] Therefore, limited information is available on which materials are most susceptible to adhesion of cariogenic streptococci. The purpose of this study was to evaluate the level of adhesion of cariogenic streptococci to various orthodontic raw materials.…”

“…14,15 The difference in adhesion between prefabricated brackets and bracket raw materials might be due to the change in surface properties during the bracket fabrication procedure, since physical and chemical changes in materials can affect relevant surface properties. 14,23 In addition, the adhesion of oral bacteria can be partly influenced by the different base morphology of the prefabricated bracket.…”

Introduction: Knowledge of adhesion patterns of cariogenic streptococci to orthodontic materials can provide valuable information on the cause of enamel demineralization during orthodontic treatment. The purpose of this study was to investigate the adhesion of 2 cariogenic streptococci strains to 7 orthodontic raw materials (3 light-cured orthodontic adhesives, 3 bracket raw materials, and hydroxyapatite) with respect to bacterial species, incubation time, and saliva coating. Methods: Each material was incubated with unstimulated whole saliva or phosphate-buffered saline solution for 2 hours. Binding assays were then performed by incubating tritium-labeled cariogenic streptococci with each raw material for 3 or 6 hours. Results: The degree of adhesion varied by material type. Generally, adhesion of cariogenic streptococci was significantly higher for bonding adhesives than for bracket materials, and adhesion to resin-modified glass ionomer was the highest. A longer incubation time generally increased bacterial adhesion, whereas saliva coating did not significantly influence bacterial adhesion. Conclusions: Bonding adhesives around brackets should be removed carefully during the bonding procedure to avoid enamel decalcification. (Am J Orthod Dentofacial Orthop 2008;133:882-8)

“…16 Among finishing and polishing techniques, it has been reported that the Sof-LexTM aluminum oxide, discs technique provides a smoother surface on composites compared to carbide bur finishing followed by the Astrobrush TM technique. 21 For this investigation, the samples were not coated with saliva because previous studies 22,23 have found that saliva coating did not significantly alter the adhesion patterns of S mutans and S sobrinus. This phenomenon is consistent with other investigations showing that saliva coating does not significantly alter the adhesion of Streptococci to the underlying materials.…”

Objective: To evaluate and compare streptococci mutans adhesion on the surface of indirect resin composites compared to direct. Materials and Methods: A total of forty standardized disk shaped samples of the four tested material were constructed in special mold and cured according manufacturer's instructions and finished and polished with soflex finishing system, then subjected to bacterial biofilm colonization and the adhered bacteria were calculated and, the collected data were subjected to statistical analysis. Results: One way ANOVA showed that there was a significant difference between the tested resin composites, and the post hoc Tukey's test showed that the lowest bacterial adhesion recorded for SR Nexco and Ceram X one with statistically significant difference compared to Z 250 and Hercuilite classic (p 0.05) Conclusion: Indirect resin composites have lower susceptibility to bacterial adhesion than do direct one in the same context the smaller the filler particle size the lowest the bacterial adhesion.
