Summary
Molar-incisor hypomineralization (MIH) and hypomineralized second primary molars (HSPM) affect over 6% of children in Rohtak, India. Early detection of these enamel defects is crucial for effective pediatric dental care.
Area of Science:
- Pediatric Dentistry
- Developmental Biology
- Public Health
Background:
- Molar-incisor hypomineralization (MIH) and hypomineralized second primary molars (HSPM) are significant developmental enamel defects in children.
- Early diagnosis of MIH and HSPM is critical for preventing complications and guiding treatment.
Purpose of the Study:
- To determine the prevalence and clinical characteristics of MIH and HSPM in school children.
- Utilized modified European Academy of Pediatric Dentistry diagnostic criteria for assessment.
- Focused on a population in Rohtak, Haryana, India.
Main Methods:
- A cross-sectional study involving 2205 children aged 3-14 years.
- Employed multistage cluster sampling for participant selection.
- Standardized clinical examinations were performed by a calibrated examiner.
Main Results:
- Prevalence rates were 6.57% for MIH and 6.41% for HSPM.
- Predominant MIH features included brown opacities and enamel breakdown.
- HSPM commonly presented as white opacities; hypomineralization in permanent canines/premolars was also noted.
Conclusions:
- The study highlights a notable prevalence of MIH and HSPM in North India.
- Increased awareness and early diagnosis are essential for managing these enamel defects.
- School-based screening programs and standardized criteria are recommended for timely intervention.

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...

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...

01:29Imperfections in Crystal Structure: Non-Stoichiometric Defects
16
Non-stoichiometric defects refer to a type of defect in the crystal structure of a compound where the ratio of its constituent elements deviates from the ideal stoichiometric ratio. There are two main types of non-stoichiometric defects: metal excess defects and metal deficiency defects.Metal excess defects occur when there is a slight surplus of metal ions than what is required by the stoichiometric ratio of the compound. For example, heating a sodium chloride crystal in sodium vapor results...

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.
