Comparison between two molar incisor hypomineralization detection criteria in epidemiological surveys.

Background: There is no consensus on which molar incisor hypomineralization (MIH) indices are more suitable for epidemiological surveys.

Aim: To compare the operational aspects and diagnostic ability of the MIH index (simplified/MIH_s and extended/MIH_e) with the MIH-Severity Scoring System (MIH-SSS) in classifying and diagnosing MIH.

Design: This cross-sectional study assessed the indices in a homogeneous group of 680 6- to 10-year-old schoolchildren in Bauru, Brazil, who had at least one first permanent molar, ensuring consistent conditions.

Sensitivity Treatments for Teeth with Molar Incisor Hypomineralization: Protocol for a Randomized Controlled Trial.

Background: The sensitivity of teeth with molar incisor hypomineralization (MIH) can affect children's quality of life and is a challenging problem for dentists. Remineralizing agents such as sodium fluoride varnish seem to reduce the sensitivity of teeth with MIH, but long-term clinical trials with large samples are still needed for more evidence about its effectiveness as a desensitizing agent before its clinical recommendation.

Objective: This randomized clinical trial aims to compare three treatment interventions for teeth with MIH and hypersensitivity.
