Efficacy Of A PVP-I Fluoride Varnish

Phase 2

Completed

• Conditions: Dental Caries
• Interventions: Drug: Test varnish; Drug: Standard varnish

• Registration Number: NCT03082196
• Lead Sponsor: Advantage Dental Services, LLC

Brief Summary

The purpose of the study is to determine the efficacy of Advantage Anti-Caries Varnish. Single-center, double-blind, controlled Phase 2 study with parallel groups of children. Subjects will be stratified by early childhood education center and then randomized to receive either test varnish or control varnish topically to the teeth. Treatment will be administered quarterly for up to 24 months. The primary outcome is surface-level primary molar caries increment (d2-4mfs) at 24- months post baseline.

Detailed Description

Objectives:

Primary

- To determine if Advantage Anti-Caries Varnish (test varnish) is superior to a control varnish containing only fluoride in the prevention of new caries lesions.

Secondary

* To establish that the response of child participants to the test varnish was not inferior to the control varnish

Arm && Interventions

Group	Intervention	Description
Test varnish	Test varnish	Advantage Anti-Caries Varnish. The active ingredients are Povidone Iodine and Sodium Fluoride .
Standard varnish	Standard varnish	The active control varnish will be the same fluoride varnish without iodine with an appropriate FDA approved food dye added to match the color of the test agent. There will be no difference in the treatment and control varnishes except for the povidone iodine.

Primary Outcome Measures

Name	Time	Method
Dental Caries for All Primary Teeth Sound at Baseline	24 months	The outcome will be the surface-level primary tooth caries increment (d2-4mfs) at two years post baseline that were sound at baseline. Caries, as measured by d2-4mfs, is the total number of surfaces with decay into the enamel (2), dentin (3) or pulp (4), missing due to caries (m), or filled with amalgam, composite or other filling material (f). This scale records whether caries is detected in any of the 4 or 5 surfaces of the tooth for up to 20 primary teeth that were sound at baseline, and has a range of 0 to 88. Higher values indicate a greater number of caries.; The measure records whether caries is present on any of the 5 surfaces of the primary molars or 4 surfaces of the other teeth.
Dental Caries for Primary Molars Sound at Baseline	24 months	The primary outcome will be the surface-level primary molar caries increment (d2-4mfs) at two years post baseline. Caries, as measured by d2-4mfs, is the total number of surfaces with decay into the enamel (2), dentin (3) or pulp (4), missing due to caries (m), or filled with amalgam, composite or other filling material (f). This scale records whether caries is detected in any of the 5 surfaces of the tooth for up to 8 primary molar teeth that were sound at baseline, and has a range of 0 to 40. Higher values indicate a greater number of caries.

Secondary Outcome Measures

Name	Time	Method
Child Response to Fifth Treatment	After fifth treatment visit	Facial Images Scale which measures the child's response using a series of five happy/sad faces from a very unhappy face (5) to a very happy face (1). The minimum value is 1 which corresponds to a very happy face and the maximum value is 5 which corresponds to a very unhappy face. The possible values of the scale are 1, 2, 3, 4, or 5.
Child Response to First Treatment	After first treatment visit	Facial Images Scale which measures the child's response using a series of five happy/sad faces from a very unhappy face (5) to a very happy face (1). The minimum value is 1 which corresponds to a very happy face and the maximum value is 5 which corresponds to a very unhappy face. The possible values of the scale are 1, 2, 3, 4, or 5.
