For which type of teeth is a sectional tray typically used?

Sectional trays are specifically designed to adapt to the unique shape and size of anterior teeth, which are the front teeth in the mouth including incisors and canines. These trays provide a better fit and improved access for procedures such as composite restorations, where precision and visibility are crucial. The design of sectional trays allows dental professionals to isolate specific teeth without affecting adjacent molar or premolar areas, which is especially beneficial in cosmetic dentistry and when applying materials like bonding agents that require a dry field.

Though sectional trays can sometimes be used in different scenarios, their primary design and effectiveness cater to the anterior teeth, making them the ideal choice for procedures involving these specific teeth. This specialized use ensures optimal outcomes, which is why it is the correct answer.
