Which of the following is true about dry angles as an isolation method?

Dry angles are triangular pads of absorbent material placed in the buccal vestibule to aid in the isolation of a specific area during dental procedures. The correct answer highlights that dry angles can be effectively used for both molars and premolars. This isolation technique is particularly useful in keeping moisture away from the treatment area by absorbing saliva and preventing it from interfering with dental work.

While dry angles are effective for various teeth, they are not suitable only for permanent teeth; they can be used in pediatric dentistry as well. They are also not limited to use with dental dams but can serve as a standalone isolation method or be used in conjunction with other techniques. Although dry angles do provide effective isolation, they do not necessarily offer better isolation than a dental dam, which provides a more comprehensive barrier against moisture.

Thus, the use of dry angles is particularly beneficial for molars and premolars, making them a versatile tool in dental procedures requiring moisture control.
