Study summary

Saccharomyces boulardii is commonly employed as a live non-pathogenic probiotic microbial feed or food supplement. S. boulardii reduces the secretion of key pro inflammatory cytokines and promotes the production of anti-inflammatory cytokines such as IL-10, which is pertinent in the context of pathogenic mechanisms in periodontitis.

Read the detailed description

One method of altering the subgingival environment is by using probiotics. Probiotics are live microorganisms, which when administered in adequate amounts, confer a health benefit on the host by passively occupying a niche that may otherwise be colonized by pathogens. This tends to limit a pathogen's ability to bind to tissue surfaces and to produce virulence factors.8 In the past few years, probiotics have been investigated for periodontal health. Studies have shown that certain gut bacteria can exert beneficial effects in the oral cavity by inhibiting pathogenic species. Teughels et al., in a study showed that application of beneficial oral bacteria subgingivally after scaling and root planing led to a more host compatible subgingival microbiota which may also effect the promotion of a beneficial host response.10 Studies have revealed that probiotic Lactobacillus strains (L. reuteri, L salivarius, L. casei, L. acidophilus) were useful in reducing gingival inflammation and the number of black-pigmented rods, including Porphyromonas gingivalis, in the saliva and subgingival plaque. Streptococcus sanguinis \& S. uberis were found to inhibit the growth of periodontopathogens \& a strong negative between Aggregatibacter actinomycetemcomitans and S. sanguinis. Weissella cibaria isolates in the form of probiotic rinse possess the ability to inhibit biofilm formation, both in vitro and in vivo.

Study arms

  • Experimental
    Study site

    Scaling and Root planing (SRP) was followed by placement of S boulardii-FOS mixture

    Procedure: Study site

  • Placebo comparator
    Control site

    Only Scaling and Root planing (SRP) was performed

    Procedure: Control site

Interventions

  • ProcedureStudy site

    The probiotic is in the form of a lyophilized powder containing approximately 5 billion colony forming units (CFU) of the Saccharomyces boulardii. At the time of administration, the probiotic mixture was mixed with fructooligosaccharide in the ratio of 4:1 to induce growth and activity in S boulardii. This was applied after scaling and root planing.

  • ProcedureControl site

    Only Scaling and Root planing was done.

What researchers measure

Primary outcomes

  1. In vitro Estimation of S. boulardii viability

    S boulardii-FOS mixture was stored for 3 weeks at 25ºC for periodic analysis (upto14 days) of microorganism viability on a selective medium. Briefly, the mixture was plated on Sabouraud's agar plates at 30°C and colony forming units (CFU) were enumerated after 24 to 48 h of incubation. Colonies were expressed as total log count per mg of sample (log10 CFU/mg).

    Time frame: up to 14 days

  2. Viability of the probiotic mixture in the periodontal pocket

    Viable cell count was determined by serial dilution method on Emmons' modification of Sabouraud's agar medium and colonies were expressed as total log count per ml of sample (log10 CFU/ml). Only colonies that were opaque, light brown, smooth and 2-3 mm in diameter were counted.

    Time frame: up to 7 days

Secondary outcomes

  1. GI

    Gingivitis (Modified gingival index; MGI) was measured at baseline and up to 6 months after treatment.

    Time frame: up to 6 months

  2. PI

    Plaque (Plaque index; PI) was measured at baseline and up to 6 months after treatment.

    Time frame: up to 6 months

  3. PPD

    Probing pocket depth (in mm) was measured at baseline and up to 6 months after treatment.

    Time frame: up to 6 months

  4. CAL

    Clinical Attachment Level (CAL) was measured at baseline and up to 6 months after treatment.

    Time frame: up to 6 months
