Summary
This study explored small bioactive compounds for direct pulp capping to regenerate dentin. Phenamil (Phen) showed potent ability to stimulate reparative dentin formation in dental pulp stem cells (DPSCs).
Area of Science:
- Biomaterials Science
- Regenerative Dentistry
- Dental Pulp Biology
Background:
- Direct pulp capping aims to regenerate reparative dentin using dental materials.
- Existing materials have limitations; small bioactive compounds for enhanced dentinogenesis are underexplored.
Purpose of the Study:
- To evaluate the pro-osteogenic and pro-odontogenic effects of four small bioactive compounds: phenamil (Phen), purmorphamine (Pur), genistein (Gen), and metformin (Met).
- To assess their potential as direct pulp capping agents for stimulating reparative dentin formation.
Main Methods:
- Assessed the effects of compounds on preosteoblastic MC3T3-E1 cells and dental pulp stem cells (DPSCs).
- Evaluated cellular differentiation and mineralization in vitro and in vivo at non-cytotoxic concentrations.
Main Results:
- All tested compounds induced dose-dependent differentiation and mineralization.
- Phenamil (Phen) demonstrated consistent and potent induction of differentiation and mineralization in vitro.
- Phen-treated DPSCs exhibited enhanced odontogenic differentiation and mineralization in vivo.
Conclusions:
- Small bioactive compounds, particularly Phenamil, show promise for direct pulp capping.
- Further research is warranted to explore their clinical application in stimulating reparative dentin regeneration.

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...

1.7K
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...
