Efficacy and Safety Evaluation of Anti-Caries Varnish

Phase 2

Completed

Brief Summary: The purpose of the study is to determine the efficacy \& safety of Advantage Anti-Caries Varnish for primary prevention. The objectives are:

1) To determine if Advantage Anti-Caries Varnish (test varnish) is superior to an active control varnish (5% Sodium Fluoride, no Povidone-Iodine) in the prevention of caries lesions in the primary dentition. Specifically, prevention of caries lesions in primary teeth that either are sound, have only d1 (white spots) lesions or unerupted at baseline; and 2) To document the safety of the test varnish.

Detailed Description: This is a single center randomized, double-blind, placebo-controlled, parallel-group trial. The treatment group will be exposed at baseline and once every three to four months after baseline for a maximum period of 24 months. The control group will be exposed to the control varnish in the same manner. 254 subjects will be enrolled. Half will be randomized to each arm. Subjects will be 6-24 mo of age and in good health. Children attending Maternal and Child Health (MCH) Immunization and Well Child programs in Pohnpei State will be enrolled. Primary Outcome Variables: 1) Surface-level dental caries lesions (d2-4mfs) at 24 months post baseline; 2) Presence/Absence of dental caries lesions (d2-4mfs \>0) at 12 months post baseline. Secondary Outcome Variable: Adverse Events

Recruitment & Eligibility

Inclusion Criteria

The subject's parent or legal guardian must provide signed and dated informed consent (parent permission form).
The subject's parent or legal guardian of the subject must be willing and able to comply with study requirements.
The subject is a 6-24 months at the time of enrollment.
The subject must be in good general health as evidenced by parent report.
The subject will have at least 1 erupted tooth that is either sound or has only a d1 (white spots) lesion.

Exclusion Criteria

Known allergy to iodine
Diagnosis of thyroid disease
Chronic, prophylactic use of antibiotics
Treatment with another investigational drug or intervention within 30 days preceding the Baseline Visit.
Visible cavities (d2-4)

Parent anticipates the child will move from Pohnpei during the next 2 years.
