Objectives: The purpose of this study was to discriminate hypomineralised enamel of permanent first molars from normal enamel by means of spectroscopic methods.
Methods: The present study was conducted using Multi spot Raman Fourier Transform Spectroscopy, Diffuse Reflectance Infrared Fourier Transform Spectroscopy (FTIR) and X-ray diffraction (XRD).
Results: Raman spectroscopy indicated significantly more B-type carbonate and hydrocarbons in hypomineralised enamel diagnosed as MIH (Molar Incisor Hypomineralisation). From XRD analysis, no changes in crystallinity of the enamel apatite could be found.
Conclusions: Using multi spot Raman-spectroscopy, a significant molecular discrimination between normal and hypomineralised enamel could be made.
Clinical Significance: Detailed surface studies are needed in order to achieve better restorative materials, specifically designed for restoration of hypomineralised enamel, and are also needed in order to understand and predict the clinical consequences of hypomineralised enamel with the condition MIH.

Aim: Assess the prevalence and severity of molar incisor hypomineralization (MIH) in children 6- to 12-year-old and correlate MIH severity with the complexity of treatment demands.
Materials And Methods: Between March and October 2023, 2,136 children were screened for MIH by two calibrated examiners. MIH severity was categorized in mild, moderate, severe, and very severe.

Renal tubular acidosis (RTA) is a group of disorders in which there is an alteration in acid-base homeostasis because of the impairment of nephrons to excrete hydrogen ions or reabsorb bicarbonate ions, resulting in chronic metabolic acidosis. RTA is an important cause of rickets, particularly 'resistant rickets'. Dental manifestations frequently reported in patients with RTA include enamel hypoplasia and amelogenesis imperfecta, affecting permanent dentition.

This review investigated the effects of hypersensitivity treatment on molar-incisor hypomineralization (MIH) using laser therapy, combined or in conjunction with other therapeutic modalities. The review was conducted according to the PICOS strategy (Population, Intervention, Comparison, and Outcome) and was performed in March 2024 using the Web of Science, PubMed, Scopus and Embase. The RoB 2 tool was employed to evaluate the risk of bias.

Background: Molar incisor hypomineralization (MIH) is estimated to affect more than 800 million people worldwide. The clinical management of MIH can be challenging. For dentists, to provide effective and high-quality dental care to people affected by MIH, it is essential that they improve their awareness, ability to describe the clinical situation, and knowledge of treatment modalities.

Objective: Success of resin infiltration for the masking of MIH-lesions remains difficult to predict, prompting suggestions to adjust the treatment protocol. This exploratory in vivo study aims to evaluate whether monitoring the resin infiltration process using transmitted light, compared to ambient light, enables a better estimation of when the infiltration process is completed, and to assess how the treatment success, i.e.
