Molar Incisor Hypomineralization: Prevalence and Treatment Needs in 7- to 9-year-old Children of Lucknow City.

Background: Molar incisor hypomineralization (MIH) is one of the most common developmental disturbances that dental practitioners encounter, which may influence the child's quality of life and can impact their future dental health.

Aim: To determine prevalence and treatment needs of MIH in children of Lucknow.

Materials and methods: A total of 800 children aged 7 to 9 years were clinically screened for the presence of MIH. All demographic details were filled in by the examiner in communication with the parents, and examination was performed using the Würzburg MIH concept.

Results: The overall prevalence of MIH in the children examined was 5.12%. A higher prevalence was found in males (7%) than in females (3.25%). The distribution of MIH was higher in the mandibular arch than in the maxillary arch. Mandibular molars were the most affected teeth, followed by maxillary incisors, and the least affected teeth were maxillary molars. On the basis of severity, 55.14% of teeth with MIH had no breakdown or hypersensitivity followed by 30.14% of teeth with hypersensitivity but no breakdown, and 7.35% of teeth had both hypersensitivity and breakdown. Based on severity, in 39.70% of teeth, the intervention suggested was fluoridated toothpaste, casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) remineralizing agent, and varnish application. This was followed by the application of sealants and low-viscosity glass ionomer cement (GIC) in 38.97% of teeth, and in 7.35% of teeth, short- and long-term restorations, including stainless steel crown (SSC), were recommended.

Conclusion: Prevalence of 5.12% was observed in children of Lucknow city. The characteristics of MIH defects were predictive of the treatment of the affected first permanent molars and incisors and can guide their management.
