Abstract	The in vitro antimicrobial activity of the active ingredient in antimicrobial magistral drug formulations and plant extracts used in folk medicine were investigated comparatively. Borax, sulfur colloid, hydrogen peroxide, benzoic acid, rivanol, brilliant green and plant extracts as active ingredients, namely: Helianthus tuberosus tuber-H2O (aqueous extract), Cydonia oblonga leaves-H2O, Allium porrum whole plant-H2O, Cistus laurifolius leaves-EtOH, Solanum muricalum-H2O, and Fumaria cilicica leaves-EtOH were studied to determine their antimicrobial activity against different bacteria and fungi (S. pyogenes, S. aureus, S. epidermidis, E. faecalis, K. pneumonia, H. influenza, P. aeruginosa, A. baumannii, E. coli, Candida albicans, C. tropicalis, C. parapsilosis, C. krusei) by using the microdilution method. The active ingredients and plant extracts showed different activities as MIC between 1->128 μg/mL. Brilliant green and rivanol as active ingredients had MIC values of 1 μg/mL against all tested microorganisms. C. oblonga leaves-H2O as well as C. laurifolius leaves-EtOH as plant extracts were indicated as having the highest antimicrobial effect in MIC value of 16 μg/ml against A. baumannii and S. pyogenes, respectively. On the other hand, F. cilicica leaves-EtOH and C. laurifolius leaves-EtOH showed the highest antifungal activity (MIC; 16 μg/mL).

Abstract	In this study, antibacterial, antifungal, antihyaluronidase, anticollagenase and antielastase activity of Hypericum bithynicum, Malva neglecta, Morus alba, Rubus discolor, Sambucus ebulus and Smilax excelsa were investigated. Methanol extracts of M. neglecta and R. discolor and all extracts of H. bithynicum were more active against Staphylococcus epidermidis. Similarly, water extracts of M. alba and S. ebulus were more active against Streptococcus pneumonia. Additionally, S. ebulus and S. excelsa had prominent antifungal activity on Candida albicans. Besides, methanol extract of M. neglecta and n-hexane extract of H. bithynicum were determined to have significant antihyaluronidase activity. Only R. discolor showed significant antielastase effect.

Abstract	Objective: To evaluate the effects of space maintainers on plaque accumulation, periodontal health and oral microflora. Subjects and methods: The study participants comprised 38 patients aged 4-10 years requiring either fixed or removable space maintainers. Plaque index, gingival index, bleeding on probing index, candidal colonization and Enterococcus faecalis were recorded just before the application of space maintainers (T0) and during treatment at the 1st (T1), 3rd (T2) and 6th (T3) month. Results: The gingival and bleeding on probing index scores increased significantly (gingival index from 0.20 ± 0254 to 0.54 ± 0417 and bleeding on probing index from 7.18 ± 9.946 to 18.07 ± 14.074) in the regions with fixed space maintainers at T3 (p < 0.01). The mean Candida counts also increased (for removable appliances from 1.90 ± 3.638 to 1.98 ± 3.318, p < 0.05, and for fixed appliances from 4.25 ± 4.587 to 4.52 ± 4.431, p < 0.001). The salivary E. faecalis counts at T3 also increased significantly with the use of fixed and removable appliances (for removable appliances from 5.93 ± 2.65 to 85.53 ± 34.1 and for fixed appliances from 4.95 ± 2.94 to 123.59 ± 29.51, p < 0.001). A positive correlation was found between the plaque (r = 0.67), gingival (r = 0.76) and bleeding on probing index scores (r = 0.76) and the candidal colonization for the fixed space maintainers (p < 0.01, p < 0.001). Conclusions: In this study, both fixed and removable space maintainers led to an increase in the number of microorganisms in the oral cavity as well as to increases in the periodontal index scores. Patients should be informed that space maintainers may serve as a source of infection and that special attention must be given to their oral hygiene.

Abstract	Context: One traditional medicines, Hypericum perforatum L. (Hypericaceae), possesses several beneficial effects against depression, ulcers, dyspepsia, abdominal pains, burns, bacterial infections, migraine headaches, and sciatica. Objective: The present study investigates the antimicrobial activity of the ethanol extract (HP-EtOH) of H. perforatum and its sub-extracts, namely n-hexane (HP-hexane), chloroform (HP-CHCl3), ethyl acetate (HP-EtOAc), n-butanol (HP-n-BuOH), and water (HP-H2O) extracts, against Streptococcus mutans, S. sobrinus, Lactobacillus plantarum, and Enterococcus faecalis. Materials and methods: For the evaluation of the antimicrobial activity, flowering aerial parts of H. perforatum were extracted with EtOH and then this extract was fractionated to obtain five sub-extracts in different polarities. Antimicrobial activities of HP-EtOH and its sub-extracts against Streptococcus mutans, S. sobrinus, L. plantarum, and E. faecalis were assessed by using colorimetric micro-well dilution at concentration ranges of 64-0.5 μg/ml as well as resazurin microplate and modified microtiter-plate assays between the ranges of 100 and 0.78125 μg/ml. Results: According to the results of the present study, HP-H2O sub-extract displayed strong antibacterial activity (MIC values 8 μg/mL) against S. sobrinus and L. plantarum, and exerted moderate activity against S. mutans and E. faecalis at 32 and 16 μg/mL concentrations, respectively. Other sub-extracts also demonstrated antimicrobial activity against S. sobrinus at a concentration of 16 μg/mL. HP-EtOAc and HP-n-BuOH showed antimicrobial activity against L. plantarum and HP-EtOAc and HP-H2O were also active against E. faecalis at the same concentrations (16 μg/mL). Conclusion: According to the results, we suggest that H. perforatum could be employed as a natural antibacterial agent in oral care products.

Abstract	A series of 6-chloromethyl-3-hydroxy-2-substituted 4H-pyran-4-one derivatives were synthesized and tested for their antimicrobial and antiviral activities. Mannich base derivatives were prepared through the reaction of substituted piperazine or piperidine derivatives on chlorokojic acid and formaline. The structures of the synthesized compounds were confirmed by IR, (1)H and (13)C NMR, ESI-MS, and elemental analysis. According to the activity studies, compounds 2-7 (MIC: 1-2 microg/mL) were found to be highly active against Bacillus subtilis and Staphylococcus aureus, while compounds 3, 5 and 6 showed significant activity against Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Acinetobacter baumannii. Also, compounds 2-7 were more remarkably active against Candida albicans and Candida parapsilosis (MIC: 4-8 microg/mL). Additionally, compound 2 was the most active one against RNA virus PI-3.

Abstract	In recent years, different biotechnological materials and modalities with antibacterial activity are being developed for oral cavity disinfection. However, the antimicrobial effects of all these materials have not been studied and understood in detail. Thus, the aim of this study was to compare the antibacterial activity of ozone therapy with dentine-bonding agents (containing antibacterial monomer 12-meth-acryloyloxydodecylpyridinium bromide (MDPB) and 10-methacryloyloxydecyl dihydrogen phosphate (MDP) and Ca(OH)₂ for deciduous teeth in vitro. The antibacterial effectiveness of the studied materials was determined by using a tooth cavity model on cylindrical cavities created in 90 deciduous second mandibular molars. Streptococcus mutans suspension was inoculated in the cavities. The teeth were distributed into six study groups (five different modalities and a negative control group). Dentine samples, which were collected from the cavities before and after the treatment sessions, were microbiologically evaluated and the materials’ antibacterial activities were compared. There were statistically significiant differences in the S. mutans counts before and after treatment (P < 0.05). In terms of antibacterial efficiency, 60-second O₃ treatment was found to be the most successful method, followed by 30-second O₃, Clearfil Protect Bond (containing MDPB), Clearfil SE Bond (containing MDP) and Ca(OH)₂ treatment. The results from this study suggested that longer exposure to ozone might have more beneficial effects in terms of antibacterial activity for reducing the levels of S. mutans.
