The goal of this work was to evaluate the safety and efficacy of the Red Light Emitted Toothbrush (R-LETB) emitting at wavelength of 663 nm with power density of 3.3 mW/cm2 in combination with 0.1%-methylene blue (MB) solution for the reduction of plaque and treatment of gingivitis. A microbiological in vitro study and a pilot clinical study were conducted. The microbiological study has shown total suppression of pathogenic flora after a 3-min exposure to the dye solution followed by a 20-sec treatment with the R-LETB. For the clinical study, 37 subjects of both sexes with gingivitis were enrolled and randomly assigned to one of two groups. Subjects in the first (treatment) group were instructed to rinse their mouth with MB solution provided for 1 min and then brush the teeth with the R-LETB and standardized toothpaste. The second (control) group used only the toothpaste and a regular toothbrush. Subjects in both groups followed their respective procedures 2 times a day (morning and evening) for 30 days. Indices of plaque, gingival bleeding, and inflammation were evaluated at 14-day and 30-day timepoints. In the both groups, all indices improved in comparison with baseline. However, the treatment group demonstrated more pronounced improvement of the studied indices that was attributed to additional anti-microbial action of red light and MB on gum tissue. Thus, the use of R-LETB with MB appears to have a multifactor therapeutic action on oral pathological microflora: mechanical removal of the bacteria and suppressing action on microorganisms due to photodynamic reaction.

Melicope pteleifolia (Champ. ex benth.) T.g. Hartley, a folk medicinal plant, is used by ethnic minorities in Bidoup–Nui Ba National Park, Lam Dong Province, Vietnam to treat effectively wound, inflammation and skin ulcer. To scientifically prove the claimed utilization and understand the mechanism of action of the plant, the in vitro and in vivo healing properties of the extract and fractions of the plant were investigated. The ethanol 70 % extract (50 – 400 mg/mL), aqueous (200 mg/mL), ethyl acetate (100 mg/mL) and petroleum ether (50 mg/mL) fractions were used to evaluate the antibacterial activities by using agar diffusion method. The healing properties were in vitro investigated through fibroblasts and keratinocytes proliferation and migration (7.8 g/mL to 250 g/mL in accordance with each extract and fraction). Besides, the macrophage-induced inhibition of the nitric oxide (NO) production was examined (15.6 – 62.5 g/mL). In addition, the excision wound model was used to test the wound healing activity on mice model. We found that the ethanol extract and the ethyl acetate fraction showed potent activity against Staphylococcus aureus, Enterococcus feacalis and Pseudomonas aeruginosa. The extract and fractions stimulated fibroblasts and keratinocytes proliferation in a concentration-dependent way. They also inhibited macrophage produce NO. In addition, mice treated by the extract formed scabs on wound excision of mice model faster than the control group. The wound healing efficiency seems to involve antibacterial, stimulating fibroblasts and keratinocytes proliferation, inhibition of macrophages produce NO.

The major nonvolatile compounds derived from extracts and fractions from Tanacetum vulgare L. flowers were determined by LC–HRMS. Major compounds in the crude extract were determined to be: six hydroxycinnamoyl quinic acids with 4,5-dicaffeoylquinic acid and twelve flavonoids and their derivatives, six of which were in the form of flavonoid-O-glucuronides. Generally, the major flavonoid aglycone in tansy was luteolin. Extracts and fractions were tested under in vitro conditions in nine cell lines - one control non-tumorogenic and eight tumor lines, whereby antitumor activity was observed after 72 hours of incubation with the aforementioned substances as determined by an MTT assay. The obtained results show the highest selectivity index for the ethyl acetate extract from Flores Tanaceti (EAFT) and for the ethyl acetate fraction of the crude extract (EACE). EAFT extract was found to exert the highest antitumor effect, followed by EACE. From the above results it becomes evident that ethyl acetate extracts of T. vulgare contain substances with high selective activity against tumor cells.

The purpose of the study was to investigate whether indocyanine green (ICG) dye damages the corneal endothelium of horses. Twenty-four corneas of 12 healthy equines, males or females, of different ages were used in this study. Only eyes with no ocular findings were used. Randomly, one eye was included in the treatment group and one in the control group. The eyes of the treatment group were exposed for 1 minute to dye ICG 0.5%. After that the endothelium of all eyes was stained with trypan blue and alizarin red S and analyzed and photographed under an optical microscope. Areas with damaged endothelial cells were manually measured and quantified using software for morphometric analysis and expressed as a percentage of cell damage. In all eyes examined areas of cell damage were observed in both corneas of the control group and the treatment group. The mean endothelial damage was 0.8 ± 0.37% in the treatment group and 0.97 ± 0.39% in the control. The Qui-square test stated that treatment and control group were not different. The ICG 0.5% did not cause acute damage to equine corneal endothelium.

This in vitro study evaluated the influence of taper angles on the internal conical connections of implant systems and of the application of chlorhexidine gel as an antibacterial agent or a polyvinyl siloxane (PVS) sealant on the reverse torque values of abutment screws after dynamic loading. The current study tested four implant systems with different taper angles (5.4°, 12°, 45°, and 60°). Specimens were divided into three groups: control (neither chlorhexidine gel filled nor silicone sealed), 2% chlorhexidine gel-filled or silicone-sealed group, and group subjected to a dynamic load of 50 N at 1 Hz for 500,000 cycles prior to reverse torque measurements. Quantitative positive correlation was observed between the taper angle degree and the percentage of tightening torque loss. However, this correlation was significant only for the 60° connection groups except in the group in which a sealant was applied ( p = 0.013 for the control group, p = 0.007 for the chlorhexidine group). Percentages of decrease in the torque values of the specimens with silicone sealant application were significantly higher compared with both the control and chlorhexidine groups ( p = 0.001, p = 0.002, p = 0.001, and p = 0.002, respectively, according to the increasing taper angles); the percentage of decrease in torque values due to chlorhexidine application was statistically insignificant when compared with the control group. The application of gel-form chlorhexidine as an antibacterial agent does not significantly affect the stability of the implant–abutment connection under dynamic loads. PVS sealants may cause screw loosening under functional loads.
