Potential agents to control enamel caries-like lesions.

Area of Science:

• Dental materials science
• Cariology
• Biomaterials

Background:

• Dental caries is a multifactorial disease characterized by demineralization and remineralization of tooth structure.
• Effective remineralization agents are crucial for controlling caries lesion progression and preserving tooth integrity.

Purpose of the Study:

• To evaluate the efficacy of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) and calcium sodium phosphosilicate (CSP) in controlling artificial caries lesion progression.
• To compare the remineralizing potential of CPP-ACP, CSP, and fluoride dentifrice.

Main Methods:

• Bovine enamel slabs with induced artificial caries lesions were subjected to surface microhardness testing.
• Specimens were treated with regular fluoride dentifrice, CSP dentifrice, CPP-ACP paste, CPP-ACP with fluoride (CPP-ACP+F), or a control.
• Mineral loss was assessed using microhardness measurements after treatment application during de-remineralization challenges.

Main Results:

• Significant differences in mineral loss were observed among the treatment groups (p=0.0161).
• CPP-ACP+F, CSP, and regular fluoride dentifrice groups exhibited lower mineral loss compared to the control group.
• The CPP-ACP group also showed a significant reduction in mineral loss compared to the control, CSP, and regular fluoride groups.

Conclusions:

• Both CPP-ACP and CSP-containing agents demonstrate remineralizing effects on artificial caries lesions.
• The degree of caries lesion control varies depending on the specific agent and its formulation, including the presence of fluoride.
