What techniques are used to keep the oral cavity free of moisture?

The choice that highlights techniques used to maintain a dry oral cavity is moisture control. This concept encompasses a variety of methods and tools employed during dental procedures to minimize salivary flow and keep the treatment area dry and accessible.

Moisture control techniques are crucial in dental settings since excess saliva can obstruct visibility and affect the efficacy of dental materials, such as adhesives and sealants. These techniques may include the use of cotton rolls, suction devices, and various barriers to help manage saliva and create a suitable working environment.

While drying agents and saliva ejectors also play a role in controlling moisture, they are specific tools rather than a broader category of techniques. Oral hygiene techniques, on the other hand, relate more to patient care and preventing oral diseases rather than specifically addressing moisture control during procedures. Thus, moisture control encompasses a more comprehensive range of practices essential for effective dental treatment.
