“…These results can be due to antibacterial compounds present in each of them. Alginate contains fluoride, which is an antimicrobial factor (16). Fluoride prevents transformation of glucose inside bacteria and has destructive effects on energy production mechanisms, glucose synthesis and metalloenzymes (17).…”

Background: Dental impressions often carry microorganisms that may cause cross-infection from patients to dental staff. Impressions should be disinfected to eliminate the risk of cross-contamination. Objectives: The aim of this study was to determine the effectiveness of three different disinfectant solutions on two commonly used impression materials. Material and Methods: Seventy-two impressions were taken from dentate arches of nine dental staff from the school of dentistry, Hamadan University of Medical Sciences. Eight successive impressions were recorded in two different impression materials for each participant as four alginate and four condensational silicones (Speedex). For each impression material, specimens were exposed to four different regimens; one was immersed in sterile water as control, and the remaining specimens were exposed to three different disinfection treatments (0.5% sodium hypochlorite, 2% Sanosil, and 6% Sanosil) for 10 minutes. The impressions were washed with distilled water for 15 seconds, were inserted into sterilized tubes, and covered with Tryptic soy broth media (TSB). The tubes were incubated at 350 ºC for 24 hours. In total, 0.01 milliliter was obtained from each tube, and inoculated on blood agar medium. Gram staining and biochemical tests were performed for bacterial detection. Data was analyzed by SPSS software using Fisher exact test. Results: Bacterial growth was observed in all impressions immersed in sterile water for 10 minutes (control group). Disinfected alginate impressions were not contaminated withany microorganisms. None of the solutions under examination were completely effective for condensational Silicone impressions. Antibacterial effects on condensational silicone impressions ranked in a decreasing order as 0.5% sodium hypochlorite, 6% Sanosil and 2% Sanosil. Conclusion: Within the limitations of this study, disinfectants were able to completely eliminate microorganisms carried by the alginate impressions. However, more efficient disinfection methods are needed to eliminate the risk of cross contamination by condensational silicone impressions.

“…Aside from the genetic and environmental factors that predispose a person to develop caries, the process itself does not occur without the existence of dental plaque or fermentable carbohydrates. Multiple studies have documented an association between an increase in number of S. Mutans in the saliva, dental plaque and increase in dental caries (2). Nowadays the serotypes of S. Mutans are considered the primary microorganism involved in caries formation, therefore correct control of S. Mutans levels is among the most important goals in the prevention and treatment of caries (3).…”

IntroductionNo studies have yet documented the bactericidal effects of TiF4, and its role in the treatment of dental caries, and no definite protocol has been introduced to regulate its use. The aim of this study was to determine the antimicrobial/bactericidal effects of TiF4 on Streptococcus Mutans (S. Mutans) and to compare it with chlorhexidine (Chx), sodium fluoride (NaF) and xylitol.MethodsThis study was conducted at the Shiraz University of Medical Sciences microbiology laboratory during March 2015 to September 2015. In this in-vitro study, first a bacterial suspension was prepared and adjusted to a 0.5 McFarland standard (equivalent to 1×108 CFU/ml). The minimal inhibitory concentration (MIC) and minimal bactericidal concentrations (MBC) of TiF4, Chx, NaF and xylitol were assessed using broth microdilution assay and disk diffusion methods. In order to neutralize the acidic nature of TiF4, we used a sodium hydroxide preparation to obtain a pH of 7.2 and repeated all of the previous tests with the neutralized TiF4 solution. We reported the final results as percentages where appropriate.ResultsThe MIC of TiF4, NaF and Chx for S. Mutans were 12.5%, 12.5% and 6.25%, respectively. At a concentration of 12.5% the inhibition zone diameters were 9 mm, 15mm and 14mm for TiF4, NaF and Chx, respectively. The MBC was 25%, 12.5% and 12.5% for TiF4, NaF and Chx, respectively. Xylitol failed to show any bactericidal or growth inhibitory effect in all of its concentrations. When we repeated the tests with an adjusted pH, identical results were obtained.ConclusionTiF4 solutions have anti-growth and bactericidal effects on S. Mutans at a concentration of 12.5% which is comparable with chlorhexidine and NaF, indicating the possible use of this solution in dental practice as an anti-cariogenic agent, furthermore the antimicrobial activity is unaffected by pH of the environment.

“…The cariogenic potential of S. mutans is manifested by the organism's ability to ferment various carbohydrates, producing large amounts of acid, and by its ability to participate in the formation of dental plaques. S. mutans is involved in the initial formation of the plaque biofilm through glucan formation [16]. Also; it has been shown that S. mutans contributes to dental caries [17].…”

Background: The present study was carried out to test the antibacterial effect of the body wall of the sea cucumber Holothuria leucospilota Brandt on Streptococcus mutans and Streptococcus salivarius. Methods: After sampling sea cucumbers from the Persian Gulf, different extractions were prepared. Then, aqueous, phosphate-buffered saline (PBS, pH 7.8), chloroform, hexane and methanolic extracts from sea cucumber body wall were screened for antibacterial activity against pathogenic bacteria S. mutans and S. salivarius using the disk diffusion method. Results: The PBS extract did not show any antibacterial or inhibitory activity; the chloroform extract, however, demonstrated high levels of antibacterial activity against S. salivarius while exhibiting low levels of activity against S. mutans. The hexane and methanolic extracts were found to show no antibacterial activity against S. mutans, but exhibited antibacterial activity against S. salivarius. Conclusions: In conclusion, the results demonstrated the possibility of utilizing sea cucumbers as a cheap source of potential antibacterial agents and for treating odontogenic diseases.
