The problem of treatment and prevention of infectious-inflammatory post extraction complications in modern surgical dentistry are still challenging, despite the great advances in this field. Many etiological factors are identified as contributing to the development of such complications, but at present scientists are paying much attention to the infectious factor, which is associated with the microflora of the tooth socket after tooth removal. According to the literature, the most common post-extraction complication during an outpatient surgical appointment is alveolitis, which accounts for 1-35% of all cases of tooth extraction. To combat an infectious etiological factor of alveolitis, dental surgeons apply topical antiseptics with a broad spectrum of action such as iodoform and chlorhexidine. As a topical antiseptic drug in the treatment and prevention of oral infectious and inflammatory complications, a domestic antiseptic, Decasan, based on decamethoxine, is becoming more widely applied. Previous studies have shown that this antiseptic has antimicrobial effect against gram-positive and gram-negative, aerobic and anaerobic bacteria; this requires further in-depth studies of its properties, which could be applied in the dental surgical practice to treat and prevent infectious-inflammatory post extraction complications. Chlorhexidine bigluconate is a cationic biguanide. Penetrating into the intracellular membranes of bacteria, it impedes the oxygen consumption and leads to the death of bacterial cells. This antiseptic is widely used in dental practice. Treatment of alveolitis is carried out by using the standard method, namely by using iodoform tamponade of the tooth socket in combination with other medicines. Iodoform (triiodomethane) is a yellow crystalline substance with a strong characteristic odor, practically insoluble in water. In dentistry, this drug is used as an antiseptic in powder form, or combined pastes. The purpose of this in vitro study is to investigate the antimicrobial properties of Decasan, chlorhexidine and iodoform against museum microbial strains. Materials and methods. Museum strains of Staphylococcus aureus ATCC 25923, Staphylococcus epidermidis ATCC 14990, Enterococcus faecalis ATCC 29212, Esherichia coli ATCC 25922, Candida albicans ATCC 10231, obtained from L.V. Gromashevsky Institute of Epidemiology and Infectious Diseases, National Academy of Medical Sciences of Ukraine, were used as studied cultures of microorganisms. The antimicrobial effect of decasan, chlorhexidine and iodoform was assessed by quantitative method of serial dilutions in broth and agar according to the order №167, dated 5.04.2007 On approval of guidelines “Determination of sensitivity of microorganisms to antibacterial drugs". Conclusion. According to the data obtained, decasan and chlorhexidine demonstrate higher bacteriostatic and bactericidal effect on the studied museum microbial strains at a concentration thousands of times lower than the concentration of iodoform.

Sodium hypochlorite (NaOCl), an effective endodontic irrigant against Enterococcus faecalis (EF), is harmful to periapical tissues. Natural pineapple-orange eco-enzymes (M-EE) and papaya eco-enzyme (P-EE) could be potential alternatives. This study aimed to assess the antimicrobial efficacy of M-EE and P-EE at different concentrations and fermentation periods against EF, compared to 2.5% NaOCl. Fermented M-EE and P-EE (3 and 6 months) at various concentrations were mixed with EF in a 96-well plate incubated for 24 h anaerobically. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of M-EE and P-EE were determined via EF growth observation. EF inhibition was quantitatively measured and compared between different irrigants using the one-way analysis of variance (ANOVA), and different fermentation periods using the independent-samples T-test. M-EE and P-EE showed MIC at 50% and MBC at 100% concentrations. There was no significant difference in antimicrobial effect when comparing M-EE and P-EE at 50% and 100% to 2.5% NaOCl. P-EE at 6 months fermentation exhibited higher EF inhibition compared to 3 months at concentrations of 25% (p = 0.017) and 0.78% (p = 0.009). The antimicrobial properties of M-EE and P-EE, at both 100% and 50% concentrations, are comparable to 2.5% NaOCl. They could therefore be potential alternative endodontic irrigants, but further studies are required.

Surgical tooth extraction can result in a number of complications. Alveolitis is an infectious and inflammatory process in the walls of a tooth socket that may occur after tooth extraction during at the oral surgery outpatient appointment. This condition is characterized by a partial or complete absence of a blood clot, called as "dry socket", and pain syndrome. There are various factors, which can contribute to the development of this process, but the most common are traumatic and infectious ones. For the local treatment of alveolitis, a number of drugs are used to eliminate inflammatory manifestations and pain syndrome. During an outpatient appointment for the treatment of alveolitis, antiseptic drugs as iodoform and chlorhexidine are most often used. Iodoform is an antiseptic widely used locally in oral surgery and in endodontics. Chlorhexidine is also widely used in dentistry as an antiseptic. The aim of this in vitro study is to investigate the antimicrobial properties of iodoform and chlorhexidine using museum strains of microorganisms. Materials and methods. Museum strains of Staphylococcus aureus ATCC 25923, Staphylococcus epidermidis ATCC 14990, Enterococcus faecalis ATCC 29212, Esherichia coli ATCC 25922, Candida albicans ATCC 10231 were used the studied cultures of microorganisms. The antimicrobial effect of iodoform and chlorhexidine was determined by a quantitative method of serial dilutions in broth and agar. For this purpose, we used iodoform suspension, which corresponded to 200.0 mg / ml of the working concentration of the agent. A 0.05% solution of chlorhexidine bigluconate was used that corresponded to 500 μg / ml of the working concentration of the agent. Results and discussion. Iodoform as powder in the studied concentrations caused an insignificant static effect on museum strains of E. faecalis, E. coli, but did not exhibit a bactericidal effect against them. In relation to the C. albicans strain, iodoform demonstrated fungiostatic properties. The S. epidermidis and S. aureus strains were resistant to iodoform. Chlorhexidine caused both inhibitory and microbicidal action on all studied strains of microorganisms.

Abstract Objective The aim of this in vitro study was to assess the antimicrobial properties of newly formulated toothpastes (four toothpastes for adults and two toothpastes for kids/babies) and a mouthrinse. Materials and Methods Newly formulated six different toothpastes and one mouthrinse of a single brand and commercially available five toothpastes and three mouthrinse were investigated for their antimicrobial activity against two oral pathogens, Streptococcus mutans and Candida albicans, by agar well diffusion assay. After incubation, the inhibition zone diameters were measured in millimeters and statistical analyses were performed. Results All experimental adult toothpastes exhibited good antimicrobial activity against S. mutans and C. albicans except the experimental toothpaste D. Experimental toothpaste B exhibited the highest antibacterial activity against C. albicans and S. mutans. Experimental toothpaste for kids showed the best antimicrobial activity against S. mutans when kids’ toothpastes were compared. None of the tested toothpastes for kids/babies showed antibacterial effects for C. albicans. Among the mouthrinse tested, Sensodyne mouthrinse showed the best results. Experimental mouthrinse showed significantly lower antibacterial activity against S. mutans then Sensodyne, Eludril, and chlorhexidine mouthrinse. Conclusion Although experimental toothpaste and mouthrinse formulations revealed good results in terms of antimicrobial activity to some specific microorganisms, further studies involving more bacterial species or analyzing the quality and efficacy of these products by other in vitro or in vivo tests are needed.

Curcumin (CUR) is a natural substance extracted from turmeric that has antimicrobial properties. Due to its ability to absorb light in the blue spectrum, CUR is also used as a photosensitizer (PS) in antimicrobial Photodynamic Therapy (aPDT). However, CUR is hydrophobic, unstable in solutions, and has low bioavailability, which hinders its clinical use. To circumvent these drawbacks, drug delivery systems (DDSs) have been used. In this review, we summarize the DDSs used to carry CUR and their antimicrobial effect against viruses, bacteria, and fungi, including drug-resistant strains and emergent pathogens such as SARS-CoV-2. The reviewed DDSs include colloidal (micelles, liposomes, nanoemulsions, cyclodextrins, chitosan, and other polymeric nanoparticles), metallic, and mesoporous particles, as well as graphene, quantum dots, and hybrid nanosystems such as films and hydrogels. Free (non-encapsulated) CUR and CUR loaded in DDSs have a broad-spectrum antimicrobial action when used alone or as a PS in aPDT. They also show low cytotoxicity, in vivo biocompatibility, and improved wound healing. Although there are several in vitro and some in vivo investigations describing the nanotechnological aspects and the potential antimicrobial application of CUR-loaded DDSs, clinical trials are not reported and further studies should translate this evidence to the clinical scenarios of infections.

AbstractThe in vitro antimicrobial properties of some chalcones (1a–1c ) and chalcone tethred 1,4-disubstituted 1,2,3-triazoles (2a–2u) towards different microbial strains viz. Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa, Aspergillus niger and Candida albicans are reported. Compounds 2g and 2u exhibited better potency than the standard Fluconazole with MIC values of 0.0063 µmol/mL and 0.0068 µmol/mL, respectively. Furthermore, molecular docking was performed to investigate the binding modes of two potent compounds 2q and 2g with E. coli topoisomerase II DNA gyrase B and C. albicans lanosterol 14α-demethylase, respectively. Based on these results, a statistically significant quantitative structure activity relationship (QSAR) model was successfully summarized for antibacterial activity against B. subtilis.

Modifying the composition of dental restorative materials with antimicrobial agents might induce their antibacterial potential against cariogenic bacteria, e.g., S.mutans and L.acidophilus, as well as antifungal effect on C.albicans that are major oral pathogens. Essential oils (EOs) are widely known for antimicrobial activity and are successfully used in dental industry. The study aimed at evaluating antibacterial and antifungal activity of EOs and composite resin material (CR) modified with EO against oral pathogens. Ten EOs (i.e., anise, cinnamon, citronella, clove, geranium, lavender, limette, mint, rosemary thyme) were tested using agar diffusion method. Cinnamon and thyme EOs showed significantly highest antibacterial activity against S.mutans and L.acidophilus among all tested EOs. Anise and limette EOs showed no antibacterial activity against S.mutans. All tested EOs exhibited antifungal activity against C.albicans, whereas cinnamon EO showed significantly highest and limette EO significantly lowest activity. Next, 1, 2 or 5 µL of cinnamon EO was introduced into 2 g of CR and microbiologically tested. The modified CR showed higher antimicrobial activity in comparison to unmodified one. CR containing 2 µL of EO showed the best antimicrobial properties against S.mutans and C.albicans, while CR modified with 1 µL of EO showed the best antimicrobial properties against L.acidophilus.
