When it comes to restoring a badly broken deciduous molar in a child, glass ionomer cement (GIC) is often the most suitable choice. GIC has several advantages that make it ideal for pediatric dentistry.

Firstly, GIC bonds chemically to the tooth structure, providing a strong adherence that can be especially beneficial for children's teeth which may be more prone to wear and tear. This chemical bond helps to seal the cavity and reduces the risk of microleakage, which is critical in maintaining the health of the remaining tooth structure.

Secondly, GIC releases fluoride over time, which is advantageous in a pediatric population. The release of fluoride helps to remineralize adjacent tooth structures and provides ongoing protection against caries, which is important in a child who may be at higher risk for dental decay.

Additionally, GIC is less technique-sensitive compared to other materials, making it easier for a practitioner, especially in a busy pediatric practice, to place effectively. It also has a coefficient of thermal expansion that is similar to that of natural tooth structure, which minimizes stress on the restoration during normal temperature changes that occur with eating and drinking.

While other materials such as composite might be aesthetically appealing and amalgam might provide strength, they may not deliver the
