effects of a composition on the oral microbiome, ph, nitrite/nitrate ratio, elastases and inflammation in oral dysbiosis

Conditions: Oral Dysbiosis

Summary: dysbiosis is a condition in which the normal function of an ecological net is altered. in dysbiosis a state of inflammation, a loss of hydration, a change in ph, a loss of the barrier function are all allies of key pathogens that initiate invasion and cytokine and pro-inflammatory mediators release that target other tissues and organs resulting in chronic inflammatory conditions. in health there is a cross-talk between the host and the microbiota in order to maintain and promote a state of eubiosis with a local and general health gain. dysbiosis reversion has not been solved with the use of antibacterials, antiseptics nor antibiotics. stop dysbiosis project is focussed on different aspects of human dysbiosis such as oral dysbiosis, skin dysbiosis, vaginal dysbiosis and cancer dysbiosis, between others including the current prospective interventional double-blind randomised clinical trial. one of the most common oral dysbiosis is periodontal and mucosa dysbiosis that courses with inflammation of the gingiva (gingivitis). this inflammation induces specific enzymes that in a later stage destroy connective tissue. the current clinical trial analyzes the effect of a composition (saliactive ®) delivered to the oral cavity via a daily use toothpaste (yotuel® microbiome toothpaste) in a group of patients with oral dysbiosis.

oral microbiota is the most diverse of the human body. it consists of mainly commensal bacteria, archea, protozoos, yeast and funghi. more than 700 species of bacteria have been identified in the mouth. in conditions of health these bacteria live in equilibrium. in inflammatory conditions, balance is lost, due to changes in microbiota or in the ecosystem with lost of the mucosa barrier function. if dysbiosis appears pathogen or fragments of these or toxic agents penetrate the body orchestrating a deep alteration of vital functions such as immune defense, nitric oxide pathways, cell cycle regulation and redox balance. periodontal dysbiosis is the consequence of the accumulation of plaque and the increase of gram negative species capable of releasing virulence factors that maintain inflammation and bleeding that perpetuate a disease-promoting ecosystem. oral hygiene is a daily personal protocol for effective delivery of active substances to the tissues of the oral cavity, mainly fluoride and antiseptics. the standard of care in the oral compound is toothpaste used 2-3 times a day. the test toothpaste including saliactive® (an olive product, betaine and xylitol) does not contain any antimicrobial agent nor antiseptic. a randomized, double-blind controlled clinical trial in 100 patients will evaluate the efficacy to reverse oral dysbiosis. microbiota profile through genetic sequenciation of the rdna16s, inflammatory markers, nitrate reducing bacteria abundance, nitrite/nitrate ratio, ph, plaque and bleeding index will be evaluated at baseline, after 2 months and 4 months of exposure to the assigned composition. two controls will be analysed, one fluoridated placebo but without the 3 active ingredients olive product, betaine and xylitol (saliactive®), and a fluoridated commercial toothpaste for gingivitis with zinc citrate. assignation of the 100 subjects will be randomized and the products are blind for the subjects and the researcher.
