Saliva Ejector
Small, straw-shaped oral evacuator, used in less evasive dental procedures
High-Volume Evacuator
used to remove saliva, blood, water, and debris during a procedure; to retract the tongue and cheek from field of operation; to reduce the bacterial aerosol caused by high-speed handpiece
Moisture Control
Keeping the operating field free of excess water, saliva, blood, tooth fragments, and excess dental materials; one of dental assistant's primary responsibilities chairside
Air-Water Syringe
Used for convenience and accuracy when rinsing the oral cavity
Guidelines For Using Air-Water Syringe
Direct syringe tip towards tooth being treated with a close distance; blow air on the mouth mirror to keep water from obstructing view; rinse and dry site when handpiece stops
Isolation of Teeth
Provides optimum results in dental procedures, keeping the tooth, quadrant, or arch dry and isolated
Teeth Isolation Techniques
Cotton roll isolation; dry angles; dental dam
Cotton Roll Isolation
Placed close to the working field to absorb excess water
Dry Angles
Pad placed on salivary gland to block flow of saliva
Dental Dam
Provides a barrier and should be routinely used for dental procedures
Dental Dam Steps
1. Mark holes 2. punch holes 3. dentist clamps tooth (floss tied to clamp to prevent swallowing) 4. stretch dam over tooth 5. place frame
Plastic Frame Is Used:
in endodontics; radiolucent
Young's Frame
Stainless steel dental dam frame
Dental Dam Napkin
placed between the patient's face and dam. Increases patient comfort and absorbs moisture
Lubricants
Lubricants can be used when dam is placed; one is used on patient's lips for comfort (zinc oxide or petroleum jelly), other is water soluble and goes on the underside of dam to help slide over teeth
Dam Punch
Makes a hole as it strikes an opening in the punch plate
Dental Dam Stamp
Used with inkpad to mark dental dam with predetermined markings
Dental Dam Forceps
Used to hold dental dam clamps; fits into holes in the clamps
Dental Dam Clamps
Primary means of anchoring and stabilizing the dental dam
Bow
Rounded portion of the clamp
Jaws
Section of the clamp that encircle the tooth (on the cervical area) and shaped into four prongs
Winged Clamp
Designed with extra extensions to help retain the dental dam
Stylus
Cutting tip
