NCT03889015

Brief Summary

This study will be conducted to evaluate the antibacterial effect of probiotic bacteria in yogurt in decreasing streptococcus mutans count in saliva and plaque, decreasing bacterial adherence and increasing salivary pH compared to xylitol-containing chewing gum after three months.

Outcome Measures

Primary Outcomes (1)

  • streptococcus mutans count in saliva

    The samples will be transported to the laboratory and cultured on selective media (dry Mitis Salivarius Agar with potassium tellurite medium and bacitracin) after serial dilutions. The plates will be incubated at 37ºC in 5-10% CO2 jar. then number of Colony Forming Units (CFU/ml) of Mutans Streptococci in saliva will be determined

    3 months

Secondary Outcomes (3)

  • streptococcus mutans count in plaque

    3 months

  • salivary pH

    3 months

  • bacterial adherence

    3 months

Study Arms (2)

xylitol chewing gum

ACTIVE COMPARATOR

Xylitol is widely used as an added sweetener in sugar-free products. It has been found to prevent dental caries through reducing dental plaque and limiting salivary streptococcus mutans counts and their produced levels of lactic acid

Dietary Supplement: xylitol chewing gum

probiotic yogurt

EXPERIMENTAL

Probiotics are live microorganisms that confer oral health benefits by adhering to the oral mucosa and surface of teeth as a part of the biofilm thus preventing the adhesion, colonization, and proliferation of cariogenic bacteria inhibiting the formation of pathogenic plaque

Dietary Supplement: Probiotic yogurt

Interventions

Probiotic yogurtDIETARY_SUPPLEMENT

Probiotics are found in different dairy products including yoghurt, that are known as carriers of probiotics. These products can be easily integrated in daily meals to reduce cariogenic streptococcus mutans bacteria in dental biofilm

Masking Details
1. Allocation concealment: Operator H.M. will choose between numbers in an opaque sealed envelope, which will be arranged by D.K. who will not be involved in any of the phases of the clinical trial. Data will be recorded on a computer by H.M. and O.S. and all records of all patients will be kept with the main supervisor M.I. 2. Implementation: D.K. will generate the allocation sequence, enroll participants, and assign participants to interventions. 3. Blinding: The assessors M.A. and R.E. will be blinded to the material assignment.
