Abstract

To date, there are no standardized protocols available in the literature for hypersensitivity treatment in molar incisor hypomineralization (MIH) patients. The aim of this study was to evaluate the efficacy of erosion–infiltration treatments with resin in children with a strong hypersensitivity and also to develop a minimally invasive diagnostic–therapeutic pathway for young MIH patients. Patients with clinical signs of MIH were enrolled according to international guidelines. A total of 42 patients (8–14 years old) with sensitivity of at least one molar and patients with post eruptive enamel fractures, but without dentin involvement or cavitated carious lesions were selected. A single superficial infiltration treatment with ICON (DMG, Germany) was performed with a modified etching technique. Sensitivity was tested with the Schiff Scale and Wong Baker Face Scale and was repeated at 12 months follow-up. All patients reported lower sensitivity values at the end of the treatment. Significant differences of sensitivity according to the Schiff scale were reported between T0 and all subsequent follow-ups, p < 0.05. The treatment of erosion infiltration with ICON resin is a minimally invasive preventive treatment that significantly improves the problem of hypersensitivity in permanent molars with MIH.

Highlights

In 2001, Weerheijm proposed the term molar incisor hypomineralization (MIH) to define a qualitative defect of the enamel from a systemic origin, which can affect 1 to all 4 of the permanent molars and can involve the permanent incisors [1].The prevalence of different MIH defects varies according to geographical areas, from 2.4% to 44% [2,3,4]
The different composition of the enamel affected by MIH and its altered crystalline structure are the cause of the main clinical issues reported by the affected patients
Considering the pre-treatment questionnaires completed by the patients’ parents/legal guardians, the possible etiological relationship proposed in the literature is confirmed (Table 1)

Summary

Introduction

In 2001, Weerheijm proposed the term molar incisor hypomineralization (MIH) to define a qualitative defect of the enamel from a systemic origin, which can affect 1 to all 4 of the permanent molars and can involve the permanent incisors [1]. The prevalence of different MIH defects varies according to geographical areas, from 2.4% to 44% [2,3,4]. Tooth enamel affected by MIH is hypomineralized and opaque with a porous appearance and it is either white, yellow or brown in color [5,6,7]. The different composition of the enamel affected by MIH and its altered crystalline structure are the cause of the main clinical issues reported by the affected patients. The high hypersensitivity of these elements is the reason for the poor quality of life during the daily oral maintenance procedures and during the consumption of food and cold drinks
