NCT02310308

Brief Summary

The effect of chewing gums containing MBE and xylitol on different variables related to caries and gingivitis in a sample of adult volunteers with a high risk for caries will be evaluated. The main result of that double-blind randomized controlled interventional trial will be that chewing gum containing MBE was more effective in reducing plaque acidogenicity, salivary mutans streptococci concentration and gingival bleeding compared to a xylitol and sugar-free chewing gum.

Study Arms (3)

xylitol chewing gum

ACTIVE COMPARATOR

Intervention chewing gum administration Each subject will be instructed to chew 1 or 2 pellets for 5 min 3 times a day (2 in the morning, 2 after the midday meal and 1 in the afternoon). Thus, the total daily intake of magnolol and honokiol in MX group will be 11.9 mg/day. The daily use of the two different chewing gums will be carried out for 12 months.

Dietary Supplement: Chewing gum administration

Eligibility Criteria

Age30 Years - 45 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Age 30-45
  • Presence of a minimum of 12 natural teeth
  • At least one surface cavitated caries lesion, but no more than three
  • Mutans streptococci and Lactobacilli \>105 CFU/ml saliva
  • Systemically healthy as assessed by a medical questionnaire
  • No use of antibiotics or participation in a clinical study in the previous 30 days
  • No allergy to any of the ingredients of the study products
  • No orthodontic banding or removable prosthesis
  • Moderate gingivitis, no current periodontitis (no sites of probing pocket depth ≥5 mm or attachment loss of ≥2 mm, apart from gingival recession).
  • Absence of dysfunction of temporo-mandibular joint.

You may not qualify if:

  • Subjects with a history of GI problems and with systemic disease that interfered with the oral ecosystem were excluded. The caries criterion was designed to include participants who are at risk of forming new lesions.
  • In addition, those participants who were already consuming more than three pieces of sugar-free chewing gum a day were excluded.
