Study summary

The aim of this study is to evaluate the efficacy of oral administration of synbiotic tablets on the clinical parameters and the levels of selected inflammatory mediators in gingival crevicular fluid (GCF) in smokers and non-smokers with gingivitis.

This study designed as a double-blind randomized placebo-controlled clinical trial.

Read the detailed description

Some patients like smokers have ongoing host response even after bacterial plaque removal achieved. Therefore efforts to develop effective treatment approaches remain an important objective in the treatment of gingivitis to prevent periodontitis especially in patients at high risk for developing periodontitis as smokers.

Smoking is a major risk factor for the incidence and the progression of periodontal diseases. The increased periodontal disease susceptibility in smokers is predominantly caused by changes in inflammatory and immune responses. Cigarette smoking also influences the amount and the composition of subgingival plaque. Smokers have higher numbers of pathogens in their resident biofilm and display an ongoing host response even after biofilm removal. Different approaches were explored to reduce the negative effects of smoking on the outcomes of periodontal therapy Synbiotic were defined as a mixture of probiotics and prebiotics that beneficially affects the host by improving the survival and implantation of live microbial dietary supplements in the gastrointestinal tract, by selectively stimulating the growth and/or by activating the metabolism of one or a limited number of health-promoting bacteria, and thus improving host welfare. Also in some cases, this may lead to a competitive advantage for the probiotics among with other bacteria.

Individual participant data

Plan to share: Yes — Randomization was performed by one researcher that had never any role in participant's treatment and clinical measurement processes (E.O.E). Patients' all measurements and treatments were made by a single researcher who doesn't know in which group participants were included (N.E.).
