Summary
Children with Deciduous Molar Hypomineralization (DMH) are more likely to develop Molar Incisor Hypomineralization (MIH). This suggests a shared cause, making DMH a potential predictor for MIH in dental health.
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Developmental Biology
Background:
- Deciduous Molar Hypomineralization (DMH) and Molar Incisor Hypomineralization (MIH) are developmental defects of enamel.
- First permanent molars and second primary molars develop concurrently, suggesting shared etiological factors.
- Understanding the relationship between DMH and MIH is crucial for early detection and intervention.
Purpose of the Study:
- To investigate the association between Deciduous Molar Hypomineralization (DMH) and Molar Incisor Hypomineralization (MIH).
- To determine if DMH can serve as a predictor for the development of MIH.
- To explore potential shared risk factors for hypomineralization in primary and permanent teeth.
Main Methods:
- Utilized data from the population-based prospective Generation R Study.
- Clinical photographs of 6,161 children's teeth were assessed for DMH and MIH.
- Prevalence and odds ratios were calculated to quantify the relationship between DMH and MIH.
Main Results:
- The prevalence of DMH was 9.0% at the child level and 4.0% at the tooth level.
- The prevalence of MIH was 8.7% at the child level and 5.4% at the tooth level.
- Children with DMH had an Odds Ratio of 4.4 for developing MIH (95% CI, 3.1-6.4).
Conclusions:
- A significant association exists between Deciduous Molar Hypomineralization (DMH) and Molar Incisor Hypomineralization (MIH).
- The findings suggest common underlying causes for both conditions.
- Clinically, DMH appears to be a valuable predictor for MIH, aiding in early identification and management.

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:31Essential Minerals for Bone Health
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
