Background: Lactobacillus spp. play a major role in the development of dental caries. Although effective methods are known for the prevention and management of dental caries, its prevalence of dental caries is increasing amongst school-age children in Ethiopia. Hence, this study is aimed to determine the association of salivary Lactobacillus spp. level and oral health factors as determinants of dental caries amongst primary school children in Harar town, Eastern Ethiopia. Methods: A cross-sectional study was conducted amongst primary school children (n = 407) using a questionnaire survey, clinical DMFT (decayed, missing, filled tooth number) examination and enumeration of salivary level Lactobacillus spp. Data were analyzed by SPSS (Statistical Package for Social Science software-version 25.0). The odds ratio was used to determine the predictors of the outcome. The data were expressed as mean ± SD. Statistical significance was defined as a p-value of less than 0.05. Results: The prevalence of dental caries was found to be 36.9% amongst primary school children. The mean DMFT value of the participants was 0.95 ± 1.57. The dental decay component was the primary observation that accounted for 84.6% of the DMFT. Almost, 67% of the saliva culture revealed a significant amount of Lactobacillus spp. count. The mean bacterial count was found to be 14.92 × 10 5 ± 22.92 × 10 5. Among various parameters analysed for association with dental caries, a number of them show positive associtation, incluing reduction in academic scores in the prevous academic year (p = 0.034), grade levels of school children 1-4 (p = 0.041), sweet food consumption habit (p = 0.003), absence of daily teeth cleaning habit (p = 0.002), absence of toothpaste use (p = 0.001), dental ache history (p = < 0.001), significant microbial load of salivary Lactobacillus spp. (p = < 0.001), acidic (p = 0.028) and basic salivary pH (p = 0.025). Conclusion: A significant salivary Lactobacillus count associated with lower grade level, sweet diet, and poor oral hygiene were found to be the determinant factors for dental caries. Thus, dissemination of oral health information is obligatory to prevent dental caries amongst primary school children in the study area.

Introduction: Aerococci has colony shape with Streptococcus viridans, so that it is usually missdiagnosed between of them. It has high difficulty on its identification, because it is rarely to be found and resistant of Antibiotic grup, called penicilin and vancomycin. Material and Method:This research used two kinds of samples, such as: fried food sold on the road and toothbrush obtained from ten respondens. Then, it needs inducing its biofilm and measuring by Tissue Culture Plate (TCP) methode and ELISA.Result: ANOVA one-way revealed that extract capsaicin has anti biofilm effect on 12.5% concentration with p=0,0000 (p<0,05) among each group. Conclusion:Extract capsaicin can be used as an alternative herbal agent to treat infection caused by Aerococcus viridans because it has antibiofilm effect. As known before, biofilm causes antibiotic resistance to treat Aerococcus viridans's infection.

“…Dental caries is one of the most chronic diseases affecting the human life and considered as one of the most crucial global oral health burdens by World Health Organization (WHO), which affects various age group of people worldwide (Hoceini et al, 2016;Struzycka, 2014). Cariogenic plaques occurred when aciduric and acidogenic bacterial strains increase with the increment frequency of exposure to carbohydrate.…”

Streptococcus mutans and Streptococcus agalactiae have been reported in human oral diseases including caries and periodontitis. Thus, the present study was performed to investigate the effect of ethyl acetate crude extract of Lasiodiplodia pseudotheobromae IBRL OS-64, an endophytic fungus isolated from Ocimum sanctum leaf against S. mutans and S. agalactiae. Disk diffusion and broth microdilution assays were used to determine the antimicrobial activities with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values. Meanwhile, the microscopic analysis was used to study the structural degeneration of bacterial cells. The fungal crude extracts demonstrated favorable antibacterial activity toward both test bacteria and produced an inhibition zone ranging from 16.0 to 21.2 mm. The MIC and MBC values of the fungal crude extract toward S. mutans and S. agalactiae were determined and the results showed that the MIC and MBC values were in the range of 125-500 µg/ml and 125-1,000 µg/ml, respectively. The time-kill study suggested that the ethyl acetate crude extract possessed bactericidal effect with concentration and time-dependent. Structural degeneration studies revealed the major abnormalities occurred to S. mutans cells after treated with the fungal crude extract where completed alterations of their morphology with the formation of cavities and collapsed cells beyond repair occurred. Therefore, the current study suggested the ethyl acetate crude extract of L. pseudotheobromae IBRL OS-64 could be an effective antibacterial agent to treat oral cavity bacteria.
