Summary
A new scoring method aids in diagnosing molar-incisor hypomineralisation (MIH) by standardizing data collection for prevalence studies. This system differentiates MIH lesions and assesses severity for better research comparisons.
Area of Science:
- Paediatric Dentistry
- Dental Epidemiology
- Enamel Defects
Background:
- Growing global interest in molar-incisor hypomineralisation (MIH) prevalence.
- Existing studies show wide prevalence variations due to non-standardized data recording.
- Need for a reliable diagnostic system for MIH in various settings.
Purpose of the Study:
- To describe the development and content of a new MIH scoring method.
- To enable standardized diagnosis and recording of MIH in epidemiological and clinical studies.
- To allow separate classification of MIH lesions and similar enamel defects.
Main Methods:
- Development of a scoring method for MIH diagnosis.
- Classification of demarcated hypomineralisation lesions and other enamel defects.
- Creation of two charting forms: a short form for screening and a long form for research.
Main Results:
- The proposed grading method classifies MIH lesions separately from other enamel defects.
- It assesses MIH severity by lesion status and affected tooth surface area.
- Two charting forms are proposed for different research needs.
Conclusions:
- The new scoring method provides a standardized approach to MIH diagnosis and data recording.
- It allows for more accurate comparisons between prevalence studies.
- Further validation and testing are required across diverse populations and age groups.
