Unilateral molar Incisor hypomineralization influences the chewing side? an observational study in children.

Objective: The aim of this observational study was to compare the chewing patterns of children with unilateral Molar Incisor Hypomineralization (MIH) to those of children without MIH and to assess how the MIH severity influences the risk of chewing deviation. The hypothesis was that children with unilateral MIH would prefer to chew on the side opposite the defect.

Methods: A total of 121 children were included in this investigation and evaluated for their preferred chewing side (PCS).

Optical coherence tomography and gray scale digital analysis as noninvasive techniques for evaluating molar-incisor hypomineralization severity: A comparative study with microcomputed tomography.

Molar-incisor hypomineralization (MIH) is a qualitative defect of dental enamel characterized by demarcated opacities present in permanent first molars and other teeth. It is considered a major clinical challenge in dentistry because it makes affected teeth more susceptible to fractures and dental caries. Its diagnosis is mainly clinical and there are few technological resources that allow for a more accurate diagnosis, especially with respect to the depth of the defect in the dental enamel.

Use of Optical Coherence Tomography for Differential Diagnosis of Severity of Molar Incisor Hypomineralization (MIH).

To evaluate descriptively and quantitatively teeth affected by enamel hypomineralization (EH) using optical coherence microtomography (OCT). Twenty teeth were classified according to the European Academy of Pediatric Dentistry's molar incisor hypomineralization (MIH) index and separated into groups according to the degree of EH severity. For each tooth, scans were performed on both the affected and the non-affected areas, and their corresponding optical images were captured.
