The Effects of an Oral Probiotic Intervention With or Without a Novel ADP-1 Toothpaste

Not Applicable

Completed

• Conditions: Oral Health
• Interventions: Dietary Supplement: Oral probiotic; Dietary Supplement: Placebo

• Registration Number: NCT05330793
• Lead Sponsor: USANA Health Sciences

Brief Summary

* Randomized double-blind, placebo-controlled trial on the effects of an oral probiotic intervention with or without a novel ADP-1 toothpaste Objective

* Determine the safety and effectiveness of oral probiotic intervention with or without a novel toothpaste and compare with placebo

Detailed Description

Hypotheses:

1. Subjects using oral probiotics will have better oral health than subjects using placebo toothpaste and placebo lozenges.

2. 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.

Primary Outcome Measures

Name	Time	Method
Gingival Index	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.
Plaque Index	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 Outcome Measures

Name	Time	Method
Halitosis	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.
SAQ	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.
Intraoral Imaging	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.
Microbial Community Analysis	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.
