RESUMEN

In this prospective pilot study, 84 patients with a history of poor oral hygiene were enrolled in an open-label, interventional, randomized controlled clinical trial. The aim was to provide preliminary clinical data on a new line of oral hygiene products containing a prebiotic and a paraprobiotic based on Lactobacillus plantarum. The recruitment rate and patient satisfaction were analyzed to estimate resources for the future primary study, and descriptive data on rebalancing of the oral microbiota were collected. The population was divided into 5 groups based on the products assigned to the patients: 1, delicate mint toothpaste (n = 20); 2, mint toothpaste (n = 12); 3, mint mouthwash (n = 20); 4, delicate mint toothpaste, mint mouthwash, and an antimicrobial toothbrush (n = 20); and 5, continued use of their usual oral care products and routine (control group; n = 12). The study duration was 28 days. All patients tolerated the products well, and there were no adverse events. The recruitment capability and procedures allowed for a realistic estimation for the future main trial. The products did not cause any changes in tooth color. The participants in group 4, who completed the treatment consisting of delicate mint toothpaste, mint mouthwash, and an antimicrobial toothbrush, reported the greatest reduction in gingival sensitivity (P ≤ 0.000; Wilcoxon signed rank test). Analysis with the Wilcoxon signed rank test revealed that all products induced a statistically significant decrease in plaque (P ≤ 0.002) and a reduction in gingival sensitivity (delicate mint toothpaste, P ≤ 0.005; mint toothpaste, P ≤ 0.015; and mint mouthwash, P ≤ 0.015). All products were effective in stabilizing the oral microbiota. The tested products showed an optimal safety profile and a statistically significant efficacy in reducing gingival sensitivity and plaque. They also stabilized the biodiversity of the oral microbiota, making it less susceptible to microbial fluctuations than the control group. Trial registration: ClinicalTrials.gov (NCT05999175).

RESUMEN

Gut dysbiosis refers to an imbalance in gut microbiota composition and function. Opuntia ficus-indica extract has been shown to modulate gut microbiota by improving SCFA production in vivo and gastrointestinal discomfort (GD) in humans. The aim of this study was to demonstrate the efficacy of OdiliaTM on gastrointestinal health by changing the microbial diversity of species involved in inflammation, immunity, oxidation, and the brain-gut-muscle axis. A randomized, double-blind clinical trial was conducted in 80 adults with gut dysbiosis. The intervention consisted of a 300 mg daily intake of OdiliaTM (n = 40) or maltodextrin as a placebo (n = 40), administered for 8 weeks. Intervention effect was evaluated using 16S metagenomics and GIQLI/GSAS scores at baseline, at 4 and 8 weeks. Eight weeks of OdiliaTM supplementation positively modulates gut microbiota composition with a significant reduction in the Firmicutes to Bacteroidetes ratio (p = 0.0012). Relative abundances of beneficial bacteria (Bacteroides and Clostridium_XIVa) were significantly increased (p < 0.001), in contrast to a significant reduction in pro-inflammatory bacteria (p < 0.001). Accordingly, GIQLI and GSAS scores revealed successful improvement in GD. OdiliaTM may represent an effective and well-tolerated treatment in subjects with gut dysbiosis.
