Restoration of choice in endodontically treated primary secondary molar in 9-year-old child is
## Core Concept
The question pertains to pediatric dentistry, specifically the restoration of endodontically treated primary and secondary molars. In pediatric dentistry, the goal is to preserve the tooth in a functional and healthy state until it naturally exfoliates or is replaced by a permanent tooth. The restoration of choice must consider the tooth's vitality, the extent of the lesion, and the child's overall oral health.
## Why the Correct Answer is Right
Stainless steel crowns (SSCs) are often considered the restoration of choice for endodontically treated primary molars due to their durability, cost-effectiveness, and ability to prevent bacterial microleakage. For a 9-year-old child with an endodontically treated primary or secondary molar, SSCs provide full coverage, which helps in distributing the occlusal forces and prevents fracture of the tooth. They are particularly beneficial in pediatric dentistry because they can be easily adapted and are less technique-sensitive compared to other restorative options.
## Why Each Wrong Option is Incorrect
- **Option A:** While composite restorations can be used for various dental restorations, they are not the preferred choice for endodontically treated molars, especially in pediatric dentistry, due to their limited durability and higher chance of microleakage compared to SSCs.
- **Option B:** Glass ionomer cements have some beneficial properties, such as fluoride release, but they are not as durable as SSCs and are more prone to wear, making them less ideal for endodontically treated molars that need to withstand occlusal forces.
- **Option D:** Amalgam restorations have been used historically but are less favored in pediatric dentistry nowadays due to concerns about mercury toxicity, their lack of adhesive properties, and the availability of more esthetic and durable options like SSCs.
## Clinical Pearl / High-Yield Fact
A key point to remember is that stainless steel crowns are highly versatile and can be used for both primary and permanent teeth, making them an excellent option for endodontically treated teeth in pediatric patients. They are particularly useful in cases where a tooth requires a full-coverage restoration to ensure its longevity and functionality.
## Correct Answer Line
**Correct Answer: C. Stainless Steel Crown.**
