# Prevalence of MIH in Young Adults At Cairo University Dental Hospital and Its Link to Dental Cavities: a Cross-Sectional Study

**Official Title:** MIH Prevalence Among Early Adulthood Patients Attending Cairo University Dental Educational Hospital and Its Correlation to Dental Caries Experience: a Cross-Sectional Study

**NCT ID:** [NCT06701552](https://clinicaltrials.gov/study/NCT06701552)

## Key Facts

- **Status:** NOT_YET_RECRUITING
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 266
- **Lead Sponsor:** Cairo University
- **Conditions:** Molar Incisor Hypomineralization, Dental Caries
- **Start Date:** 2024-11
- **Completion Date:** 2025-02
- **CT.gov Last Update:** 2024-11-22

## Brief Summary

We are conducting a study to understand how often MIH (Molar Incisor Hypomineralization) occurs and whether it is linked to a higher chance of dental cavities (caries).

MIH is a condition where the enamel (the hard outer surface) of the first permanent molars and incisors (front teeth) doesn't develop properly, making these teeth more prone to damage and decay. We are looking at whether patients with MIH have more cavities in their teeth compared to patients without MIH.

This study aims to help us learn more about the connection between MIH and dental health, so we can improve care and prevention strategies for kids at risk of cavities.

## Eligibility

- **Minimum age:** 18 Years
- **Maximum age:** 30 Years
