“…Zonuz and colleagues studied the growth of S. mutans (ATCC 25175) and S. sanguis (ATCC 10556) on atmospheric air, CO 2 , and cigarette smoke (Kent gold, Kent lights, and Bahman) and the results of this study indicated significantly increased the growth of S. mutans in cigarette smoke and CO 2 with the greatest impact of Bahman. They have also reported mutans/sanguis ratio of 1, 0.84, and 0.98 in Kent gold, Kent lights, and Bahman, respectively (19). The results of this study is similar to the present study, regarding greater growth of streptococcus in cigarette smoke, and CO 2 , however, the growth of S. mutans was greater in their study than S. sanguis, while in the present study, it was vice versa.…”

Background: Streptococcus mutans and Streptococcus sanguis are two important bacteria of the oral microflora. S. mutans is the most important cause of dental caries and S. sanguis plays an important role in formation of microbial plaque. Objectives: The present study aimed to determine the effect of cigarettes and hookah on thebacterial growth of S. mutans and S. sanguis. Methods: The standard strains of S. mutans (PTCC = 1683) and S. sanguis (PTCC = 1449) were cultured on blood agar and incubated for 48 hours in different environments, including atmospheric air, carbon dioxide, three types of cigarette smoke (Winston, ultralight Winston, and Kent), and fruity tobacco. Then, the diameter of colonies was measured and data was compared using statistical tests, such as one-way ANOVA. Results: Bacterial growth was 80%, 100%, 61%, 48%, and 59% in carbon dioxide, Winston, Kent, Ultralight Winston, fruit tobacco, respectively, for S.mutans (P < 0.001) and 134%, 38%, 169%, 105%, and 61%, respectively, for S. sanguis, which were higher than ordinary air (P < 0.001), in addition, the growth of S. mutans was more than S. sanguis in the Winston group. Conclusions: These findings showed that the growth of S. sanguis was significantly greater than S. mutans in all groups, except in the Winston group.

“…Cigarette smoke condensate (CSC) has been reported to elicit morphological and transcriptional changes that suggest epithelialto-mesenchymal transition (EMT) in cultured bronchial epithelial cells (Polk 2012). Zonuz et al (2008) reported that the growth of Streptococcus mutans and Streptococcus sanguis is accelerated in the vicinity of CSC. CSC has also been reported to interfere with the adhesion and biofilm formation in contact with Streptococcus mutans and Candida albicans cells (Baboni et al 2010).…”

The aim of the study was to investigate the effect of cigarette smoke on the production and characterization of exopolysaccharides (EPSs) produced by Bifidobacterium. Cigarettes of Shanhua brand (nicotine: 1.1 mg, tar: 11 mg) were utilized to prepare a cigarette smoke condensate (CSC). The standard strain of Bifidobacterium animalis was cultured in MRS media under anaerobic addition of CSC. The results showed that CSC significantly decreased the growth of B. animalis as well as EPSs and acetic acid production. Furthermore, two EPSs fractions (Fr-I and Fr-II) were isolated and purified for chemical and molecular determination. By comparison with control, CSC was found to be of great impact on EPSs carbohydrate composition. The molecular weight mass of Fr-I changed from 3.33×10 5 g/mol (without CSC) to 2.99×10 5 (with CSC). In conclusion, in vitro studies revealed that CSC was directly able to affect the production of metabolites for B. animalis, which could be an essential factor in certain pathological disorders.

Environmental smoke exposure associated with increased prevalence of dental caries in low-income children

Dental caries are of serious concern as increasing numbers of cases of early childhood caries are seen. Oral hygiene and the development of dental caries is a challenging issue to address in any child. However, children in lower socioeconomic groups are disproportionately affected when compared with their higher-income peers. Low-income children are found to be twice as likely to have dental problems, with a reported prevalence of up to 50 % . Several environmental factors have been found to play a role in this difference, including passive smoke exposure, lead exposure, and poor nutritional intake. While lead exposure and nutrition have been studied extensively, the association between passive smoke exposure and dental caries in children is less well known. This review will consider these environmental risk factors, focusing primarily on passive smoke exposure and its association with the development of dental caries. We will also propose potential strategies, on the basis of a comprehensive understanding of both existing published research and communitybased interventions, as a means of addressing the health disparities that contribute so dramatically to this problem.
