Outcome Measures

Primary Outcomes (1)

  • The primary outcome will be incidence of white spot lesions on the labial surfaces of the maxillary incisors, canines and premolars

    Assessed from high-resolution digital photos

    12-24 months

Secondary Outcomes (1)

  • The secondary outcome is the prevalence of WSLs at debonding and one year after debond

    12 months

Study Arms (2)

Fluoride varnish

EXPERIMENTAL

During the course of the orthodontic treatment, the patients are regularly checked every 6th week. At the end of each such occasion, the clinical staff will apply the test varnish with a small brush in a thin layer around the base of the braces on the maxillary teeth. The varnish is let to dry and the subjects are instructed not to eat or drink within 60 minutes after the application. The NFV test varnish has mint flavour and the active ingredient is ammonium fluoride dissolved in ethanol, water and an acrylate polymer.

Other: Fluoride varnish

Varnish without Fluoride

PLACEBO COMPARATOR

During the course of the orthodontic treatment, the patients are regularly checked every 6th week. At the end of each such occasion, the clinical staff will apply either the placebo varnish with a small brush in a thin layer around the base of the braces on the maxillary teeth. The varnish is let to dry and the subjects are instructed not to eat or drink within 60 minutes after the application. The placebo varnish has an identical composition as the test varnish except for the ammonium fluoride. Thus, taste, colour and handling properties are the same.

Other: Fluoride varnish

Interventions

The study will employ a double-blind, randomized placebo-controlled design with two parallel groups. The intervention will start at onset of the fixed appliances and will be finalized one year after debond. The primary outcome will be incidence of white spot lesions on the labial surfaces of the maxillary incisors, canines and premolars, as assessed from high-resolution digital photos. The secondary outcome is the prevalence of WSLs at debonding.
