The husk fibres of Areca catechu (areca nut) are reported to be used by the people of rural areas of Dakshina Kannada, Karnataka for cleaning their teeth. The beneficial effects of these plant materials are not scientifically proven, so the study was carried out to estimate the antimicrobial properties of A.catechu against common oral pathogens. These antimicrobial properties in addition to mec...
Seven pimarane type-diterpenes re-isolated from Viguiera arenaria Baker and two semi-synthetic pimarane derivatives were evaluated in vitro against the following main microorganisms responsible for dental caries: Streptococcus salivarius, S. sobrinus, S. mutans, S. mitis, S. sanguinis and Lactobacillus casei. The compounds ent-pimara-8(14),15-dien-19-oic acid (PA); ent-8(14),15-pimaradien-3beta...

Although a broad range of biological and pharmacological activities of apigenin have been reported, the mechanism(s) behind its antibacterial effects are not fully understood. In this study, we investigated the synergistic antibacterial activity of apigenin in combination with existing antimicrobial agents against oral bacteria. The combination effect of apigenin was evaluated against oral bact...
biogenic amines both in the peripheral and central nervous systems. Unlike AADC, which is common to catecholaminergic and serotoninergic neurons, the preceding enzymes, tyrosine and tryptophan hydroxylases respectively, are siteand substrate-specific. In addition, hydroxylation represents the rate-determining step in amine synthesis and is subjcct t o several mechanisms of regulation. If a biop...
We examined whether colonization of selected oral pathogens is associated with gastric precancerous lesions in a cross-sectional study. A total of 119 participants were included, of which 37 were cases of chronic atrophic gastritis, intestinal metaplasia, or dysplasia. An oral examination was performed to measure periodontal indices. Plaque and saliva samples were tested with real-time quantita...
