Preventive Potential of Fluoride Sealants in Adolescent Orthodontic Patients

July 2, 2026 updated by: Sigmund Freud PrivatUniversitat

The Potential of Fluoride Sealants in Preventing White Spot Lesions During Orthodontic Treatment

The aim of this trial is to investigate the potential of using an adhesive bonding agent that also acts as a fluoride sealant when placing fixed orthodontic appliances in adolescent patients, as an alternative to regular bonding agents.

The main question it aims to answer is:

- Does an adhesive fluoride sealant reduce the prevalence of white spot lesions in orthodontic adolescent patients after an observation period of 3 months?

Participants who need orthodontic treatment and who agree to take part in this study will have their orthodontic appliance placed using regular adhesive on one side of their upper jaw and fluoride sealant on the other.

White spot lesion prevalence will be assessed using the Enamel Decalcification Index (EDI) at baseline and after 3 months.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Group Sealant
Side of the maxilla in which a fluoride releasing bonding agent was used
Other: Use of fluoride releasing bonding agent to place the orthodontic appliance
In this prospective study using the split-mouth design, patients will be followed for 3 months after placing the fixed orthodontic appliance. The orthodontic appliance will be placed according to the clinic's standards using an adhesive bondin agent that simultaneously works as a fluoride sealant especially provided for this purpose.
Control Group
Side of the maxilla in which a regular bonding agent was used
Other: Use of a bonding agent to place the orthodontic appliance
In this prospective study using the split-mouth design, patients will be followed for 3 months after placing the fixed orthodontic appliance. The orthodontic appliance will be placed according to the clinic's standards using an adhesive especially provided for this purpose.
