The aim of this study was to point out the prevalence of hypomineralised molars and incisors and emphasize importance of this condition in paediatric dentistry. This condition is defined as hypomineralisation of one or more first permanent molars frequently affecting incisors and referred to as molar incisor hypomineralisation (MIH). Aetiology of MIH has not been fully clarified and numerous aetiological factors have been cited. Hypomineralised molars are more prone to caries, cause severe restorative problems and are frequently extracted due to serious damage and caries complications. Incisors can present demarcated enamel opacities, while enamel breakdown is uncommon. Considering the fact that permanent first molars with severe defects demand complex treatment, they represent a serious problem for the patient as well as for the dentist.

Molar incisor hypomineralization (MIH) is a developmental defect that affects the enamel tissue of permanent teeth. Clinicians may observe a range of opacities in the affected teeth, varying from white to creamy, yellow, and brown. Of particular interest is an etiology of MIH that has not been rigorously elucidated.

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.

Aim: To investigate the association between molar incisor hypomineralization (MIH) and periodontitis in adolescents.
Methods: A population-based study was undertaken of Brazilian adolescents aged 18 and 19 years (n = 2515). MIH was assessed according to Ghanim's criteria.

Aim: This prospective clinical study aimed to clinically investigate the efficiency of (GIC) glass-ionomer cement application (Ionostar Plus + Easy Glaze, VOCO) in reducing hypersensitivity in permanent molars affected by molar incisor hypomineralisation when assessed immediately (15 min) and 12 weeks after its application.
Materials And Methods: Children with at least one hypersensitive MIH-affected permanent molar (MIH-TNI-3 or 4). The pre-treatment status was evaluated and only included if they did not receive a tooth-specific in-office desensitizing treatment within one month.

Molar incisor hypomineralization (MIH) presents a multifaceted challenge in pediatric dentistry, impacting diagnostics, clinical management, resource accessibility, and psychosocial care. The condition's complexity is exacerbated by diagnostic variability, overlapping clinical symptoms, and the need for tailored treatment approaches. This study aims to explore the key challenges associated with the management of MIH in pediatric dentistry, including diagnostic precision, clinical management, resource limitations, interdisciplinary care, long-term follow-up, and psychosocial impact, and to propose strategies for overcoming these obstacles.
