Summary
Molar incisor hypomineralisation (MIH) affects permanent molars and incisors, increasing caries risk and restorative challenges in children. Early detection and management are crucial for pediatric dental health.
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Developmental Biology
Context:
- Molar incisor hypomineralisation (MIH) is a developmental defect affecting enamel quality.
- It frequently impacts first permanent molars and incisors.
- The aetiology of MIH remains multifactorial and not fully understood.
Purpose:
- To determine the prevalence of hypomineralised molars and incisors.
- To highlight the significance of MIH in pediatric dentistry.
- To underscore the clinical challenges associated with severe MIH defects.
Summary:
- MIH presents as hypomineralisation of enamel in one or more first permanent molars, often involving incisors.
- Hypomineralised molars exhibit increased susceptibility to caries and significant restorative issues.
- While incisors may show demarcated opacities, enamel breakdown is less common.
Impact:
- Severe MIH defects in permanent molars necessitate complex and extensive dental treatments.
- This condition poses considerable challenges for both child patients and dental practitioners.
- Understanding MIH prevalence is vital for effective pediatric dental care strategies.

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.

01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
