  Purpose
The purpose of this study was to compare with a clinical randomized controlled split-mouth design study the changes in the therapeutic effect of infiltrating versus sealing proximal caries lesions and placebo treatment after 1, 2 and 3 years. The outcome was lesion progression, evaluated by radiographic techniques.

Condition Intervention Phase
Dental Caries Drug: Resin infiltration / adhesive Drug: Placebo Phase 2 Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment

Primary Outcome Measures:
  • Pair-wise radiographic lesion progression [ Time Frame: 1, 2, and 3 years ]
    Changes in the therapeutic effect of infiltrating versus sealing proximal caries lesions and placebo treatment after 1, 2 and 3 years. The outcome was lesion progression, evaluated by radiographic techniques.


Secondary Outcome Measures:
  • Digital-subtraction radiography lesion progression [ Time Frame: 1 year ]
    Changes in the therapeutic effect of infiltrating versus sealing proximal caries lesions and placebo treatment after 1 year. The outcome was lesion progression, evaluated by subtraction radiography.


Enrollment: 37
Study Start Date: January 2008
Study Completion Date: March 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment with Infiltrant/Adhesive
In this split-mouth design study, one of the three randomly selected approximal lesions will be treated with an infiltrant resin, one will be treated with an adhesive resin.
Drug: Resin infiltration / adhesive
Treatment at baseline of one caries lesion with a resin infiltration conducted under rubber-dam isolation with the Icon-DMG pre-product; treatment at baseline of another caries lesion with an adhesive under rubber-dam isolation with the Prime Bont NT - Dentsply.
Other Names:
  • Infiltrant: Icon pre-product, DMG
  • Adhesive: Prime Bond NT, Dentsply
Placebo Comparator: Placebo, placebo treatment
In this split-mouth design study, one of the three randomly selected approximal lesions will be treated with a placebo treatment: At baseline one caries lesion was cleaned with a microbrush for 30 seconds and the procedure was repeated after two minutes.
Drug: Placebo
In this split-mouth design study, one of the three randomly selected approximal lesions will be treated with an infiltrant resin, one will be treated with an adhesive resin.
Other Name: Placebo (cleaning of surface)
