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. Read more about this study

About this study

Official title: To Evaluate the Clinical Efficacy of the Probiotic Toothpastes in Patients With Moderate to Severe Gingivitis

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.

Read the detailed 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Gingival Index

    The gingivitis will be evaluated at baseline and different timepoint post-intervention by Gingival index. Gingival index for individual teeth= Total of gingival index of each tooth/No. of teeth present. The minimum score of TMQHPI is 0 (Normal gingival). The maximum score of TMQHPI is 3 (severe gingivitis).

    Measured: 0, 4, 5, 9 weeks

Secondary outcomes (5)
  1. Plaque index

    The plaque accumulation will be evaluated by Turesky-Modified of the Quigley- Hein Plaque Index(TMQHPI) and plaque index at baseline and different timepoint post-intervention. TMQHPI Index= Total score/The number surfaces examine. The minimum score of TMQHPI is 0. The maximum score of TMQHPI is 5.

    Measured: 0, 4, 5, 9 weeks

  2. Saliva sIgA

    The saliva sIgA level will be evaluated at baseline and different timepoint post-intervention by ELISA.

    Measured: 0, 4, 5, 9 weeks

  3. Halitosis

    The halitosis will be evaluated at baseline and different timepoint post-intervention by halitosis meter.

    Measured: 0, 4, 5, 9 weeks

  4. Questionnaire assessment

    The oral health will be evaluated by Oral Health Impact Profile (OHIP) questionnaire. The oral health will be evaluated by Gut Health Assessment questionnaire.The questionnaire is comprised of 26 items.The questionnaire will be evaluated at baseline and different timepoint post-intervention.

    Measured: 0, 4, 5, 9 weeks

  5. Analysis of oral microbiota

    The change in composition of oral microbiota will be evaluated at baseline and different timepoint post-intervention using real time PCR.

    Measured: 0, 4, 5, 9 weeks
