- Long term effects of the ICON technique on patients with enamel hypomineralization: a systematic reviewPublication . Benguigui, Sacha Abraham; Palmeira, Carlos; Begonha, Maria JoãoEnamel hypomineralization, commonly called molar-incisor hypomineralization (MIH), is a developmental defect in the mineralization of tooth enamel. It is a disorder that mainly affects the first permanent molars and central incisors and causes the appearance of more or less dark stains on the affected teeth, which makes them less aesthetic and more susceptible to pathologies. The consequences for the patient are multiple and include hypersensitivity, increased occurrence of caries lesions, decreased durability of dental restorations, decreased enamel resistance to chewing or acid attacks, and even aesthetic changes, causing psychological and behavioural problems in affected children. The ICON technique, which consists of infiltrating the stain with resin after superficial abrasion with hydrochloric acid, is one of the available treatments. The main objective of this study is to compare and evaluate the long-term effects of the ICON technique in patients affected by MIH. To achieve that, a bibliographic search was carried out in the following databases: PubMed, Science Direct and Scielo. The articles found were screened based on the PRISMA criteria, using inclusion and exclusion criteria. Methodological quality was assessed using the Joanna Briggs Institute tool for case series, cohorts and randomized clinical trials. We combined data from the theoretical and empirical literature in order to compare and synthesize the results of the various studies on the proposed topic. The analysis of the studies included in this work on ICON resin infiltration highlights its consistent positive results in terms of improving aesthetics, dental hypersensitivity and structural integrity of the teeth. These notable improvements in aesthetics, reduction of post-treatment pain and reduction in the risk of enamel fracture, suggest the durability of the treatment and its potential as a long-term solution in the treatment of MIH. Despite these results, limitations such as variations in study parameters emphasize the need for further research in order to fully establish the efficacy of ICON compared to alternative treatments. Overall, infiltration with this resin appears to be a promising and minimally invasive option for treating dental hypomineralization, and continued investigation into its clinical application should be ensured.
