Periodontitis and tooth decay are common dental diseases. There are some bacterial risk factors such as Streptococcus mutans, Aggregatibacter actinomycetemcomitans and Candida albicans complications, tubers of Cyperus rotundus was used to determine the antimicrobial effect of fungi. Considering the increasing resistance of bacteria and fungi to antibiotics and their alcoholic and aqueous extracts and essential oil on Streptococcus mutans, Aggregatibacter actinomycetemcomitans and Candida albicans, as well as an examination cytotoxicity on gingival fibroblast cells. Alcoholic and aqueous extracts and essential oil prepared from tubers of Cyperus rotundus. After bacterial and fungal cultures, the inhibition zone, Minimum inhibitory concentrations (MIC), and Minimum Bactericidal Concentration (MBC), were studied. Cytotoxicity was also evaluated using the Methyl tetrazolium test (MTT).The results showed that Cyperus rotundus alcoholic extract had the greatest effect on inhibition of growth and death of Streptococcus mutans, Aggregatibacter actinomycetemcomitans. According to the present study, Cyperus rotundus extract can be considered as a suitable candidate for the treatment and prevention of periodontitis and tooth decay.

ABSTRACT Background and objectives To study the effect Achyranthes aspera, 0.2% aqueous chlorhexidine gluconate and Punica granatum oral rinse on salivary Streptococcus mutans count in children. Materials and methods A total of 60 children of 8 to 12 years of age were randomly allocated into 3 groups. Group A was given 0.2% chlorhexidine mouthwash, group B was given 10% A. aspera mouthwash and group C was given 15% P. granatum mouthwash. The day 1 saliva samples were collected from the subjects and innoculated onto mitis salivarius bacitracin (MSB) agar. The colony counts were obtained by a clinical microbiologist who was blinded to the subject allocation. Plaque scores were then recorded by the investigator with the help of a volunteer. Following this, they received a thorough scaling and polishing. Subjects in each group were then provided with 140 ml of the respective mouthwash, as a daily supervised rinse after breakfast and before sleeping as per instructions. Following mouth rinsing, the children were instructed not to eat or drink for 15 minutes. At the 7th day, unstimulated saliva was again collected from the subjects of all 3 groups, inoculated onto MSB agar and colony count was obtained. Modified Quigley- Hein plaque index was also evaluated for the refreshed score at this stage. Colony counting was done using loop method and statistical analysis was done using Statistical Package for the Social Science (SPSS) software version 21. Results All the three mouthwashes showed statistically significant reduction of S. mutans count and plaque index after 7 days, i.e. chlorhexidine (p < 0.001 for reduction in S. mutans count and p < 0.05 for plaque score reduction), A. aspera (p < 0.01 for reduction in S. mutans count and p < 0.05 for plaque score reduction) and P. granatum (p < 0.01 for reduction in S. mutans count and p < 0.05 for plaque score reduction). Chlorhexidine had marginally better results in reducing S. mutans count. Conclusion • Efficacy of chlorhexidine, A. aspera and P. granatum was statistically significant with respect to reduction of S. mutans count with chlorhexidine being marginally better than the other two, • All the three mouthwashes were found to be at par when plaque index values from baseline and after interception of 7 days was calculated, • Punica granatum has better antimicrobial effect than A. aspera.

Objectives: The aim of this cross-sectional in vivo study was to assess the effect of green tea and honey solutions on the level of salivary Streptococcus mutans. Study design: A convenient sample of 30 Saudi boys aged 7–10 years were randomly assigned into 2 groups of 15 each. Saliva sample was collected for analysis of level of S. mutans before rinsing. Commercial honey and green tea were prepared for use and each child was asked to rinse for two minutes using 10 mL of the prepared honey or green tea solutions according to their group. Saliva samples were collected again after rinsing. The collected saliva samples were prepared and colony forming unit (CFU) of S. mutans per mL of saliva was calculated. Results: The mean number of S. mutans before and after rinsing with honey and green tea solutions were 2.28* 108(2.622*108), 5.64 *107(1.03*108), 1.17*109(2.012*109) and 2.59*108 (3.668*108) respectively. A statistically significant reduction in the average number of S. mutans at baseline and post intervention in the children who were assigned to the honey (P=0.001) and green tea (P=0.001) groups was found. Conclusions: A single time mouth rinsing with honey and green tea solutions for two minutes effectively reduced the number of salivary S. mutans of 7–10 years old boys.
