Management of Teeth Affected by Molar Incisor Hypomineralization Using a Resin Infiltration Technique—A Systematic Review

Abstract

In recent years, an increase in children diagnosed with molar incisor hypomineralization (MIH) has been observed. Children with MIH show a high failure rate with conservative treatment. The ICON® system (DMG, Hamburg, Germany), which is an infiltration of decalcified lesions with resin, may strengthen the tooth structure, improve its aesthetics, and cure hypersensitivity. The following article is a systematic review based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Scientific articles in the PubMed and Google Scholar databases describing the use of the ICON system in the treatment of MIH published in the years 2012–2022 were analyzed. Two independent study authors selected publications that show that the ICON system can be used during the treatment of children with MIH. So far, in the literature, there are no standardized protocols for the dental treatment of patients with hypomineralization of the incisors using the ICON system. Therefore, clinicians rarely use this method of treatment. The ICON system may be successfully used to infiltrate tooth decalcification in children with MIH. However, the depth of infiltration and the achievement of enamel hardness after such therapy are not precisely defined.

Clinical evaluation of resin infiltration treatment masking effect on hypomineralised enamel surfaces

“…The use of infiltrants for masking enamel discolourations in hypomineralized teeth has spread more recently [ 9 ]. We evaluated the qualitative and quantitative clinical outcomes of resin infiltration on teeth with MIH for 6 months.…”

“…It was reported that this high fluorescence is due to bacterial porphyrins in the carious lesion [ 15 , 17 ]. In MIH, opacities structure differs from caries etiology [ 9 , 18 ]. DIAGNOdent readings were recorded high in tooth with irregular enamel structure without dental caries as MIH [ 19 ].…”

“…The defective enamel has a smooth surface with average thickness; however, the enamel structure is defective. As a characteristic of MIH is that the cervical third is spared, but the two other thirds might be affected [ 9 ].…”

Resin Infiltration of Non-Cavitated Enamel Lesions in Paediatric Dentistry: A Narrative Review

“…RI was also used in the management of anterior teeth with MIH [ 91 , 92 ]. Earlier studies by Kim et al [ 93 ] found that the MIH teeth treated with RI showed significant colour changes after one week of treatment.…”

Comparison of aesthetic treatments for molar-incisor hypomineralisation: Systematic review and meta-analysis

“…Molar incisor hypomineralisation (MIH) is a developmental defect that involves hypomineralisation of the enamel, most frequently targeting one or more of the first permanent molars and incisors ( Bulanda et al, 2022 ). The prevalence worldwide is increasing, along with other associated dental complications among these patients ( Almuallem and Busuttil-Naudi, 2018 ).…”
