Summary
Maternal tobacco use during pregnancy, hypertension, delivery complications, and early childhood otitis media are linked to a higher prevalence of hypomineralized primary second molars (HPSMs). These findings highlight key risk factors for this common dental issue.
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Developmental Biology
Background:
- Hypomineralized primary second molars (HPSMs) are characterized by enamel opacities affecting one to four primary molars.
- Understanding systemic factors associated with HPSMs is crucial for early identification and intervention.
Purpose of the Study:
- To investigate systemic exposures linked to the prevalence of hypomineralized primary second molars (HPSMs) in children.
- To identify potential risk factors during pregnancy and early childhood.
Main Methods:
- A cross-sectional study involving 731 eight-year-old children and their mothers.
- Data collection through structured questionnaires and clinical assessment of HPSMs using the modified-DDE index.
- Statistical analysis using Poisson multiple regression with a temporal hierarchical approach.
Main Results:
- The prevalence of HPSMs was 9.4%.
- Maternal hypertension (PRa=1.73) and tobacco use during pregnancy (PRa=2.44) were significantly associated with higher HPSM prevalence.
- Complications during delivery (PRa=1.83) and early childhood otitis media (PRa=1.68) also showed increased HPSM prevalence.
Conclusions:
- Maternal tobacco use, hypertension, delivery complications, and early childhood otitis media are significant risk factors for HPSMs.
- These findings underscore the importance of prenatal and early childhood health in primary tooth development.
- Targeted preventive strategies addressing these systemic factors may reduce HPSM incidence.

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...

01:31Essential Minerals for Bone Health
5.8K
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...

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.

01:15Teeth
1.5K
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...

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
