To Evaluate the Efficacy of Probiotics Toothpastes in Improvement of

Status Completed

Clinical Trial Summary

Gingivalis is the one of the most common diseases of oral cavity, and affects more than 75% of adult populations worldwide. The present studies demonstrated that the addition of probiotics in toothpastes or mouthwashes could reduce dental plaques and gum inflammation, and improve oral health. This study was designed to assess the effectiveness of probiotic toothpastes during the supportive therapy of moderate to sever gingivalis patients.

Clinical Trial Description

Previous studies have shown that probiotics could improve oral health including periodontal diseases, dental caries and halitosis via inhibiting periodontal pathogens, modulating periodontal microbiome, and regulating oral mucosal immunity. Heat-killed probiotics strain, Lactobacillus paracasei GMNL-143 or Lactobacillus rhamnosus GMNL-464 possessed great coaggregation abilities with oral pathogens and removed them after rinsing mouths. Besides, GMNL-143 can decrease the secretion of pro-inflammatory cytokines, increase the expression of anti-inflammatory cytokines, and inhibit the growth of dental pathogen Streptococcus mutans. Hence, it is suggested GMNL-143 or GMNL-464 probiotic toothpastes can ameliorate oral health of patients with gingivitis. In this clinical study, the effectiveness of probiotic toothpastes during the supportive therapy of moderate to sever gingivalis patients will be clarified. A randomized, double-blind, crossover and placebo controlled clinical trial will be formed. This clinical trial will be conducted at Kaohsiung Medical University Chung-Ho Memorial Hospital, Kaohsiung, Taiwan. 60 subjects with moderate to severe gingivitis will be enrolled. This trial will last for 9 weeks, starting from the time when the subjects begin to use probiotic toothpastes. Subjects who pass the screening phase will enter the first visit (week 0) and return in the 4th, 5th and 9th weeks. Subjects will be randomized to one of two groups, using probiotic toothpastes (GMNL-143 or GMNL-464) or placebo toothpastes to brush teeth for two minutes twice daily for 4 weeks, and then will enter a 1 week-washout and afterward will be crossed over to the opposite treatment for 4 weeks. Subjects will receive assessments of plaque index and gingivitis index, collection of samples including plaque, gingival cervical fluid and saliva, and questionnaires of oral health impact profile (OHIP) and gastrointestinal health at each visit. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
