A CLINICAL CASE OF APPLICATION OF «ICON-INFILTRANT» SYSTEM IN THERAPEUTIC DENTISTRY

Abstract

Modern scientific and technological progress offers a new standard of treatment of odontopathology - infiltration of enamel with resins to seal cracks, chips and to level the surface in the affected area. The aim of the research is to introduce a conservative method for caries treatment using the polymer system "Icon" in the practice of therapeutic dentistry. Patient P., 20 years old, applied to the Department of Propaedeutics of Therapeutic Dentistry of PDMU with complaints of a tingling sensation from chemical stimuli, which disappeared immediately after their removal and the appearance of white matte spots on the vestibular surface of the maxillar teeth in the frontal area. From the anamnesis - the spots appeared after removing the brace system, which the patient had been wearing for 3 years. After the clinical examination, we diagnosed acute superficial dental caries 13,12,11,21,22,23. The treatment was performed in one visit with the Icon Vestibular system. Teeth are cleaned of plaque with a brush and fluoride-free toothpaste "Depural Neo". Under application anaesthesia with Sol. Lidocaini 10%, we isolated teeth with the rubber dam system. The lesions were treated with etching gel (Icon-Etch) 15% hydrochloric acid solution, left for 2 min, then washed off with water for 30 seconds, dried with dry air. To ensure high-quality adhesion of polymer resins, complete moisture removal was performed using ethanol-containing conditioner "Icon-Dry" for 30 seconds, followed by thorough air drying. To infiltrate the lesion, the vestibular nozzle was wound on the syringe "Icon-Infiltrant", infiltrate was carefully applied with a small excess on the etched enamel and left for 3 minutes. Excess was removed with floss and photopolymerized using "Icon-Infiltrant" for 40 seconds. For the second time, having screwed a new vestibular nozzle onto the "Icon-Infiltrant" syringe, the resin was applied for 1 minute. Excess material was removed and polymerized with ultraviolet light for 40 seconds. The rubber dam system was removed. The oxygen-inhibited layer was removed and the vestibular surfaces of the teeth were polished with the help of polishing discs and heads. As a result of the treatment, most of the stains disappeared, the colour, the shine of the tooth enamel 13,12,11,21,22,23 and the surface relief were restored. In 1 and 3 months after treatment, the visual and tactile examination of the vestibular surfaces of teeth revealed that the achieved aesthetic result slightly improved – the sizes of spots, which had been noticeable on the day of treatment decreased. The obtained result satisfied the patient both on the day of infiltration and in the long term. Follow-up examinations every 3 months during the year are recommended. Thus, this method allows us to stop the development of caries and non-carious lesions. It does not require anaesthesia; during treatment, intact areas of tissue are preserved and not damaged. Consequently, a high therapeutic and aesthetic result is achieved, several teeth can be cured in one session, and treatment lasts for an average of 15 minutes.
