Bioactive glass (BAG) effectively prevents dental erosion in primary teeth. A 6% BAG concentration showed the most significant reduction in tooth wear and microhardness loss.
Area of Science:
- Dental Materials Science
- Pediatric Dentistry
- Biomaterials Research
Background:
- Dental erosion is a significant concern in primary teeth, leading to tooth structure loss.
- Developing effective preventive strategies is crucial for maintaining children's oral health.
Purpose of the Study:
- To evaluate the efficacy of bioactive glass (BAG) in preventing dental erosion in primary teeth.
- To determine the optimal concentration of BAG for erosion prevention.
Main Methods:
- Primary teeth specimens were pretreated with varying concentrations of BAG (2-8%) or sodium fluoride.
- Specimens underwent in vitro erosive challenges.
- Erosive tooth loss, microhardness, surface morphology, and mineral composition were analyzed.
Main Results:
- BAG treatments significantly reduced enamel and dentin erosion and microhardness loss.
- The 6% and 8% BAG concentrations demonstrated the greatest protective effects.
- Increased BAG concentrations led to more surface deposits rich in calcium, phosphorus, and silicon.
Conclusions:
- Bioactive glass, particularly at 6% concentration, is highly effective in preventing dental erosion in primary teeth.
- BAG shows strong potential for protecting dentin from erosive challenges.

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...

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.
