caryophyllene and Periodontal-Diseases

This study aimed to investigate the antimicrobial activity of β-caryophyllene against periodontopathogens as well as its inhibitory effects on the expression of inflammatory cytokines and production of volatile sulfur compounds by lipopolysaccharide and periodontopathogenic enzymes, respectively.. The antimicrobial activity of β-caryophyllene againstPorphyromonas gingivalis, Tannerella forsythia, and Treponema denticola was investigated via a susceptibility assay using a microplate reader. THP-1 cells were treated with lipopolysaccharide in the presence or the absence of β-caryophyllene, and the expression and production of inflammatory cytokines were then analyzed by a real-time reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assay. After fluorescence-labelling lipopolysaccharide, the effect of β-caryophyllene on the binding of lipopolysaccharide to the cell wall was investigated via flow cytometry. The spent culture media of P. gingivalis was shaken with or without β-caryophyllene and gaseous volatile sulfur compounds (VSCs) were measured by a gas chromatograph.. β-caryophyllene showed strong the antimicrobial activity against periodontopathogens. It also reduced lipopolysaccharide-induced expression and production of cytokines, thereby inhibiting the binding of lipopolysaccharide-binding to toll-like receptors by interfering with the complex of lipopolysaccharide and CD14 or lipopolysaccharide-binding protein. β-caryophyllene also inhibited the emission of gaseous VSCs produced byP. gingivalis.. β-caryophyllene may improve periodontal health via antimicrobial activity against periodontopathogens, reducing inflammation caused by lipopolysaccharide, and by neutralizing VSCs.

Periodontal disease is a highly prevalent illness that affects many dogs, reaching up to 85 % prevalence in individuals over the age of 4 years. Currently the drug of choice for combating the formation of dental plaque in these animals, the etiologic agent of the disease, is chlorhexidine, which has several side effects reported. Thus, surveys are conducted throughout the world in order to identify potential substitutes for antimicrobial therapy and prevention of periodontal disease. The objective of the work was to evaluate the antimicrobial activity of β-caryophyllene against bacteria from dog's dental plaque in vitro and in vivo. The minimum inhibitory concentration was evaluated by agar microdilution assay, the induction or inhibition of bacterial adherence by sub-inhibitory concentrations in 96-well plates, and reduction of dental plaque formation in mongrel dogs subjected to topical solution with β-caryophyllene for 15 days.. Results showed minimum inhibitory concentrations above 100 mg/mL for 25 % of the isolates, 100 mg/mL for 3 %, 50 mg/mL for 25 %, 25 mg/mL for 12 %, 12.5 mg/mL for 19 % and 6.25 mg/mL for 16 %. Bacterial adherences of three Enterococcus sp., one Streptococcus sp., one Haemophilus sp., one Aerococcus sp., one Bacillus sp. and one Lactococcus sp. isolates were inhibited by subinhibitory concentration. One Lactococcus sp., one Bacillus sp. and one Streptococcus sp. were stimulated to adhere by concentrations of 0.19, 1.56 and 0.78 mg/mL, respectively. In vivo assay showed reduction in dental plaque formation by β-caryophyllene, with final plaque coverage of 23.3 ± 2.6 % of the total area of the teeth, with significant difference compared with chlorhexidine group (37.5 ± 3.7 % - p < 0.05) and negative control group (65.5 ± 2.5 % - p < 0.001).. The results showed that β-caryophyllene has antimicrobial activity against the proliferation of dog's dental plaque-forming bacteria representing a suitable alternative to the use of chlorhexidine in prophylaxis and treatment of periodontal disease of dogs.
