Referring to the post-treatment clinical photographs, the molar teeth are restored with which type of crowns?

• A. Prefabricated stainless-steel crowns
• B. Molded aluminum crowns
• C. Cast gold crowns
• D. Metal colored acrylic crowns

Answer: (A)

In pediatric dentistry, post-treatment photos that show molars covered with uniform, full-coverage metal crowns typically indicate prefabricated stainless-steel crowns. These crowns come as preformed shells selected to fit the size of the tooth, then trimmed and crimped to create a snug margin and proper occlusion. They restore the entire clinical crown with strong, durable coverage, which is especially useful for primary molars that undergo heavy chewing forces or when decay or following pulp therapy demands full protection.

This option is favored because it requires minimal tooth reduction, allows quick placement, and yields reliable longevity in children. The margins seal well and proximal contacts can be adjusted during seating, making them efficient in a busy clinical setting.

Other crown types have drawbacks in this context. Molded aluminum crowns are older and less durable. Cast gold crowns, while durable, are less practical for primary molars due to higher cost and more extensive preparation. Metal-colored acrylic crowns offer aesthetics but are less durable and wear more quickly. The metallic, full-coverage appearance in the photos aligns best with prefabricated stainless-steel crowns.
