Summary
Severe molar-incisor hypomineralisation (MIH) in children is linked to higher rates of dental caries and hypersensitivity. Understanding these associations is crucial for providing individualized dental care to affected children.
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Developmental Biology
Background:
- Molar-incisor hypomineralisation (MIH) affects tooth enamel development, leading to potential dental issues.
- Understanding the prevalence and severity of MIH in children is essential for targeted interventions.
Purpose of the Study:
- To determine the distribution and severity of MIH in 8-9-year-old children.
- To investigate the relationship between MIH severity and hypersensitivity, caries, and involvement of incisors and second primary molars (SPM).
Main Methods:
- A cross-sectional study involving 3013 children, with 538 diagnosed with MIH based on European Academy of Paediatric Dentistry criteria.
- Data collected by a calibrated dentist and analyzed using bivariate logistic regression.
Main Results:
- Nearly half of children with MIH had at least one severely affected molar; incisors were affected in 51.9% and SPM in 29.6%.
- Children with severe MIH showed significantly higher odds of hypersensitivity (OR 5.62) and dentine caries (OR 10.32).
Conclusions:
- High prevalence of hypomineralised incisors and SPM observed in children with MIH.
- Severe MIH increases the likelihood of incisor affection, dentine caries, and hypersensitivity, necessitating specialized dental care.

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...

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...

Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

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...

642
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

3.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
