This study is ongoing, but not recruiting participants.

ClinicalTrials.gov Identifier:
NCT01726179
First received: November 1, 2012
Last updated: September 28, 2016
Last verified: September 2016
  Purpose
the goal of the project is to investigate the clinical efficacy of management of early caries lesions by resin infiltration and to further scrutinize the patient stress experiences.

Condition Intervention
Dental Health Caries Device: Icon infiltration Device: control

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Treatment
Official Title: Efficacy of Resin Infiltration of Proximal Caries Lesions in Primary Molars: Randomized Clinical Trial

Further study details as provided by DMG Dental Material Gesellschaft mbH:

Primary Outcome Measures:
  • caries progression after infiltration [ Time Frame: 1 yr, 2 yrs, 3 yrs ]
    To test the efficacy of caries infiltration with a low viscosity resin (Infiltrant; DMG, Hamburg, Germany) in controlling the progression of non-cavitated proximal lesions in primary molars in comparison to conventional non invasive treatment (daily plaque control brushing with fluoride dentifrice and flossing).


Secondary Outcome Measures:
  • stress reaction during treatment [ Time Frame: baseline ]
    To evaluate dental anxiety and stress reactions in relation to the caries infiltration procedure in comparison with a dental examination appointment and conventional resin restoration appointment.


Estimated Enrollment: 66
Study Start Date: December 2012
Estimated Study Completion Date: August 2019
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Icon infiltration
Icon infiltration regarding instructions for use
Device: Icon infiltration

Patients and their guardians will be instructed to use dental floss to remove dental biofilm in both proximal sites once a day and to brush teeth with fluorated toothpaste twice a day. Besides that, test lesion will be infiltrated with a low viscosity resin (Icon, DMG, Hamburg, Germany). The test lesions will be treated using Icon (DMG, Hamburg, Germany) following the instruction for use.

A sub-sample with children with indication for a composite restoration in at least one proximal surface will be selected for the analysis of dental anxiety and stress.

Active Comparator: control
conventional non invasive treatment
Device: control

Patients and their guardians will be instructed to use dental floss to remove dental biofilm in both proximal sites once a day and to brush teeth with fluoridated toothpaste twice a day.

A sub-sample with children with indication for a composite restoration in at least one proximal surface will be selected for the analysis of dental anxiety and stress.


Detailed Description:
The aim of this study is to test the clinical efficacy of caries infiltration to arrest proximal caries lesions in primary molars. It was hypothesized that infiltrated lesions (test lesions) will progress significantly less than non infiltrated lesions (control lesions). Additionally, it was hypothesized that dental anxiety and stress related to caries infiltration will be significantly less than dental anxiety related to a conventional restorative procedure. The study will be a controlled clinical trial with a split mouth design and blind evaluation of the outcome (caries progression). Caries progression will be evaluated annually, 12, 24, and 36 months after treatment.
