Abstract: BACKGROUND: Dental fluorosis seriously affects the aesthetics of patients, and traditional oral filling materials have defects.
OBJECTIVE: To evaluate the clinical efficacy of Icon (DMG, Hamburg, Germany) penetrating resin in the treatment of dental fluorosis.
METHODS: ICON penetrating resin was used to treat dental fluorosis in 30 patients (200 teeth in total) admitted to Hebei Eye Hospital from December 2018 to December 2019. After treatment, patients’ subjective feelings about the treatment, including satisfaction with aesthetics, tooth sensitivity after treatment, and dignity with the treatment process, were counted through a questionnaire. The relationship between the size of the lesion, the tooth surface index of fluorosis, and the number of dental erosion required for the filling was calculated to investigate the effect of the lesion on the treatment.
RESULTS AND CONCLUSION: (1) The aesthetic satisfaction of 30 patients was higher at 3, 6, and 9 months after treatment than that before and immediately after treatment (P < 0.05). Among 30 patients, dentin hypersensitivity was not detected in 19 patients after resin restoration, and dentin sensitivity disappeared within 72 hours in 11 patients. All patients were satisfied with the treatment. (2) Before treatment, the proportion of tooth surface index of fluorosis scoring 1, 2, and 3 was 65.50%, 30.50%, and 4.00%,respectively. Immediately after treatment, the proportion of the tooth surface index of fluorosis scoring 0, 1, and 2 was 83.00%, 16.00%, and 1.00%, respectively. Spearman rank correlation analysis demonstrated a correlation between the number of dental erosion during the operation, the size of the lesion, and the tooth surface index of fluorosis. (3) It is concluded that ICON infiltration resin has a highly effective and stable effect for treating dental fluorosis. However, the size of the fluorosis lesion and the tooth surface index of fluorosis may affect the number of dental erosion during the procedure, which also needs to be taken into account by the practitioner.
