“…Jang et al, (Jang et al, 2017) demonstrated that 0.3% SDIC solution possessed strong bactericidal efficacy against Salmonella enterica serovar Thyphimurium even for 1 min treatment at -10°C, whereas, 0.1% glutaraldehyde worked for 10 min treatment at 25°C. Since many experimental researches have indicated its increased resistance to inactivation by organic material, slow decomposition and release of HOCl, capacity to maintain an appropriate level of available chlorine, low level of toxicity and lower corrosiveness to metal, plastic and rubber (Block, 2001;Bloomfield and Miles, 1979;Coates, 1966;Kaye et al, 1991) , the use of SDIC instead of NaClO has been recommended. However, there have been few reports to investigate the effectiveness of SDIC as a disinfectant to dental field (Heling et al, 2001;Patel et al, 2012) .…”

Dental materials are inevitably contaminated with oral microorganisms. To prevent transmission of infectious diseases, impressions need to be disinfected. In the present study, we examined the disinfection effects on impression materials and biofilm removal by sodium dichloroisocyanurate (SDIC) . Exponentially growing Streptococcus mutans, Escherichia coli, Staphylococcus aureus and Candida albicans, and dental plaque bacteria were suspended in phosphate buffered saline (PBS) and exposed for 1, 5 and 10 min to 1 mL of the 10 ppm, 100 ppm, 1,000 ppm, and 10,000 ppm SDIC solutions. The bactericidal effect was evaluated by colony forming units of each microorganisms. Moreover, the effect of SDIC solution on S. mutans biofilm was examined. Bactericidal effects of SDIC solutions on oral bacteria on dental impression surfaces were assessed and the surface quality of dental casts after immersion in SDIC solution for 30 min was observed under a scanning electron microscope. The number of all bacterial strains, including plaque bacteria, were significantly decreased by SDIC solution treatment in a dose-dependent manner. Significant S. mutans biofilm removing activity of SDIC was observed in 1,000 and 10,000 ppm solution. The number of oral bacteria adhering to the surfaces of impressions markedly decreased following 10-min immersion in the 1,000 ppm SDIC solution. The 30-min immersion of dental impression in the 1,000 ppm SDIC solution did not adversely affect the surface roughness of dental casts. The results indicate that SDIC Solution is useful to deactivate oral bacteria on dental impression.

“…Moreover, a huge amount of papers has reported the higher efficacy of NaDCC with respect to NaOCl against a wide range of microorganisms, such as Gram-positive and Gram-negative bacteria as well as fungi and viruses that, in many cases, are relevant to hospital settings [2][3][4][5][6]14]. Many experimental results have recommended NaDCC instead of NaOCl for its biocidal effectiveness, such as its: increased resistance to inactivation by organic material, slow decomposition and release of HOCl, capacity to maintain an appropriate level of available chlorine without affecting the pH of the water, low level of toxicity and lower corrosiveness to metal, plastic and rubber [2,3,6,13].…”

Bactericidal and Fungicidal Activity in the Gas Phase of Sodium Dichloroisocyanurate (NaDCC)

et al. 2016

Sodium dichloroisocyanurate (NaDCC) is usually employed as a disinfectant for the treatment of water, environmental surfaces and medical equipment principally for its effectiveness as a microbicide agent. In this study, we explore the possibility of a new use for NaDCC by investigating the microbicidal activity of chlorine, which derives from the hydrolysis of NaDCC mediated by air humidity, and by testing its effect on the neutralization of microbes present in domestic waste. NaDCC was inserted in a plastic garbage can where LB agar plates, with different dilutions of a known title of four different microorganisms (Escherichia coli, Staphylococcus aureus, Debaryomyces hansenii and Aspergillus brasiliensis), were weakly inserted. The molecular chlorine (Cl2) levels present in the garbage can were quantified using an iodometric titration. The gas emitted in the garbage can presented a strong microbicide effect, inhibiting the proliferation of all four microorganisms and for four consecutive weeks, thus showing that NaDCC hydrolysis, mediated by air humidity, is able to ensure the decontamination of restricted environments, avoiding the proliferation of both Gram-positive and Gram-negative bacteria as well as fungi.
