Abstract:

White spot lesions are defined as enamel superficial and subsurface demineralization. The resin infiltration technique has proved to be a valid micro-invasive alternative to traditional conservative therapy. This article aims to present the treatment of initial carious lesions after fixed orthodontic treatment by resin infiltration.
A 15-year-old clinically healthy girl without allergies or general diseases was admitted to the dental office for consultation and treatment. Intraoral examination revealed initial carious lesions on the vestibular surface of multiple teeth in the upper and lower jaw. The lesions were irregular in shape, located in the cervical, proximal, and bracket fixation areas. Their color ranged from chalky white to yellow-brown, with a loss of gloss and transparency and a lack of clear boundaries. A resin infiltration treatment was performed.
The resin infiltration technique can mask the enamel discoloration and achieve a satisfactory aesthetic result. It can be successfully used in patients with white spot carious lesions after fixed orthodontic treatment.
