Chapter 36 - Moisture Control Flashcards
Where should the dental dam clamp be fitted?
The clamp is designed to fit on the cervical area of the tooth below the height of contour at, or slightly below, the cementoenamel junction.
What is the purpose of winged clamps?
Winged clamps have extensions to help retain the dental dam.
What type of teeth are posterior clamps used for?
Posterior clamps are for the maxillary and mandibular posterior teeth.
What is the function of anterior clamps?
Anterior clamps retract the gingiva on the facial surface and improve visibility.
Why are ligatures important on clamps?
Ligatures are important safety measures that make it possible to retrieve a clamp should it accidentally become dislodged and then inhaled or swallowed by the patient.
What is the dental dam stabilizing cord?
A disposable latex cord that is an alternative to the conventional clamp method of securing the dental dam.
What sizes is the dental dam stabilizing cord available in?
The cord is available in three sizes: Extra small, small, and large.
How does the dental dam stabilizing cord function during insertion?
During insertion, the cord is stretched so that it becomes narrow and slips easily between the teeth.
What happens to the dental dam stabilizing cord once placed?
Once placed and released, the cord resumes its original shape and holds the dam tightly in place.
What factors should be considered in dental dam preparation?
Preparation should accommodate dentist preference, tooth or teeth involved, and procedure to be performed.
What are the two methods used for dental dam placement?
The two methods are the one-step method and the two-step method.
What is the main difference between the one-step and two-step methods?
The main difference is the sequencing in placement of the clamp and the dental dam.
What special application may be required for anterior teeth?
A cervical or anterior clamp may be required if the gingival third of a tooth is to be restored and if the gingival tissue must be retracted for better exposure.
What can be used to stabilize the cervical clamp?
Softened stick compound may be used for this purpose.
What should be done when working with a fixed bridge?
Punch a hole for each fully crowned tooth, but do not punch holes for the teeth that are replacing missing teeth.
