Vitamin D deficiency is linked to persistent primary teeth (PPT) in children. Lower serum 25(OH)D levels increase the likelihood of developing PPT, indicating a significant risk factor.
Area of Science:
- Pediatric Dentistry
- Endocrinology
- Human Genetics
Background:
- Dental development and eruption are complex processes influenced by genetic and environmental factors.
- Vitamin D plays a crucial role in calcium homeostasis and bone metabolism, impacting various physiological processes.
- Variations in the vitamin D receptor (VDR) gene and serum 25(OH)D levels have been implicated in several health conditions.
Purpose of the Study:
- To investigate the association between serum 25(OH)D levels and vitamin D receptor (VDR) gene polymorphisms with dental developmental disturbances.
- To determine if low 25(OH)D levels or specific VDR gene polymorphisms are risk factors for persistent primary tooth (PPT) and delayed tooth eruption (DTE).
Main Methods:
- A case-control study evaluated 183 children across two datasets.
- Dataset 1 assessed the association between PPT, serum 25(OH)D levels, and VDR polymorphisms.
- Dataset 2 analyzed VDR polymorphisms (rs2228570, rs739837) in children with DTE versus controls, using T-tests and chi-square tests.
Main Results:
- Children with PPT exhibited significantly lower serum 25(OH)D levels compared to controls (p=.047).
- Vitamin D deficiency was associated with a higher likelihood of presenting PPT (OR = 2.36; 95%CI: 1.51, 3.70).
- No significant association was found between the studied VDR polymorphisms (rs739837, rs2228570) and delayed tooth eruption.
Conclusions:
- Vitamin D deficiency is identified as a significant risk factor for persistent primary tooth (PPT).
- The findings highlight the importance of adequate vitamin D levels for normal dental development and eruption.
- Further research may explore targeted interventions for vitamin D deficiency to prevent dental anomalies.

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Teeth
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...
Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
Tooth Anatomy
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...
Bone Disorders
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...
