About this study

Hypotheses:

  • Subjects using oral probiotics will have better oral health than subjects using placebo toothpaste and placebo lozenges.
  • Subjects using oral probiotics and ADP-1 toothpaste will have better oral health than subjects using oral probiotics and regular toothpaste, and subjects using regular toothpaste and placebo lozenges.

  • Able to understand and comply with study procedure
  • Able to provide written informed consent
  • Able to come to Roseman Dental Clinics in South Jordan for a 90-minute pre-screening to determine eligibility

  • Breastfeeding, pregnant or trying to become pregnant
  • Currently taking or have taken any of the following within 30 days of enrollment:
  • Oral probiotics
  • Antibiotic medications
  • Antifungal medications (e.g., nystatin, clotrimazole, ketoconazole, griseofulvin)
  • Antiseptic medications
  • Immunosuppressant and/or chemotherapeutic medications
  • Medications that could affect gum response measurement (e.g., calcium channel blockers, cyclosporin, anti-seizures like phenytoin and related drugs, anti-inflammatory agents)
  • Frequent alcohol consumption (> 2 drinks per day, or > 8 per week for women, or > 15 per week for men)

Primary outcomes

  1. Gingival Index

    Time frame: 8 weeks

    • Gingival Index measures gingival condition of the marginal and interproximal tissues (mesial, lingual, distal, facial) separately on the basis of 0 to 3 with 0=Normal gingiva; 1= Mild inflammation - slight change in color and slight edema but no bleeding on probing; 2= Moderate inflammation - redness, edema and glazing, bleeding on probing; 3= Severe inflammation - marked redness and edema, ulceration with tendency to spontaneous bleeding.

  2. Plaque Index

    Time frame: 8 weeks

    • Plaque index is used as a method of recording the presence of plaque on individual tooth surfaces. These surfaces are mesial, distal, buccal and lingual.

Secondary outcomes

  1. Halitosis

    Time frame: 8 weeks

    • Halitosis will be measured using a digital bad breath checker. The instrument is a small device with a sensor that sits near your mouth. This instrument senses volatile sulfur compounds or VSCs and produces a parts-per-billion (ppb) measurement of the foul-smelling compounds.

  2. Intraoral Imaging

    Time frame: 8 weeks

    • Intraoral imaging of tooth decay can be measured in at least one of the following methods: (1) Using traditional intraoral imaging camera in the dental clinics to visualize tooth decay on the tooth surface, and (2) Using a laser fluorescence pen to detect tooth decay.

  3. SAQ

    Time frame: 8 weeks

    Self-Assessment Questionnaire will consist of no more than 100 questions examining quality of life across one or several of these domains: (1) social well-being, (2) mental well-being, (3) physical well-being, (4) oral health and (5) dental hygiene and halitosis.dental hygiene and halitosis.

  4. Microbial Community Analysis

    Time frame: 8 weeks

    Oral swabs from the gum line will be collected using DNA Genotek OMNIgene-ORAL swab kits and stored in the accompanying swab storage tube for microbial community analysis. qPCR testing will be performed in house in USANA.
