Summary
This study found hypomineralized second primary molars (HSPM) in 4.9% of 5-year-old Dutch children. Most affected teeth showed demarcated opacities, indicating a need for monitoring early childhood dental enamel defects.
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Developmental Biology
Background:
- Dental enamel hypomineralization is a common defect affecting tooth quality.
- Primary molars are crucial for mastication and guiding permanent teeth.
- Limited data exists on hypomineralization prevalence in primary molars among young children.
Purpose of the Study:
- To determine the prevalence of hypomineralized second primary molars (HSPM) in 5-year-old Dutch children.
- To describe the clinical appearance of HSPM in this population.
Main Methods:
- Cross-sectional observational study involving 386 Dutch children aged 5 years.
- Adapted Molar Incisor Hypomineralization (MIH) criteria for assessing second primary molars.
- Clinical examination to identify and categorize hypomineralized enamel defects.
Main Results:
- The prevalence of HSPM was 4.9% at the child level and 3.6% at the tooth level.
- Demarcated opacities were the most frequent finding (87% of HSPM).
- Posteruptive enamel loss was observed in 40% of HSPM.
Conclusions:
- HSPM affects a notable percentage of 5-year-old Dutch children.
- Demarcated opacities are the primary clinical presentation of HSPM.
- Early detection and management of HSPM are important for pediatric oral health.

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...

01:21Tooth 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.

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
