Dental Assisting

Demonstrate a safe single-handed instrument transfer between assistant and operator.

Transfer hinged instruments and loaded material instruments while controlling their working ends.

Position the dental light to illuminate maxillary and mandibular treatment areas without obstructing the operator.

Differentiate the purposes and limitations of high-volume evacuation and the saliva ejector.

Position high-volume evacuation to control spray, retract tissue, and protect the patient during a simulated procedure.

Select cotton rolls, gauze, dry angles, saliva ejectors, or high-volume evacuation for a given moisture-control need.

Coordinate retraction, evacuation, and instrument transfer during a basic four-handed dentistry sequence.

Identify the parts of a dental bur: shank, neck, and head.

Distinguish friction-grip, latch-type, and straight-handpiece bur shanks by their physical features.

Match each bur shank type to a compatible fast-speed or slow-speed handpiece attachment.

Identify common bur shapes, including round, pear, inverted-cone, straight-fissure, and tapered-fissure burs.

Match common bur shapes to their basic cutting or finishing functions.

Differentiate carbide burs, diamond instruments, and polishing attachments by construction and intended use.

Interpret common bur markings, packaging information, and single-use indications.

Inspect a bur for contamination, wear, corrosion, or damage and determine whether it may be used, reprocessed, or discarded.

Compare fast-speed and slow-speed handpieces by speed, torque, attachments, cooling needs, and common uses.

Identify the external controls and functional parts of a fast-speed handpiece.

Identify the motor, straight attachment, contra-angle attachment, latch head, and prophy angle used with slow-speed handpieces.

Assemble and disassemble a slow-speed handpiece system in the correct sequence.

Insert, secure, test, and remove a friction-grip bur from a fast-speed handpiece safely.

Insert, secure, test, and remove latch-type and straight-handpiece burs from compatible slow-speed attachments safely.

Perform pre-use safety checks for bur retention, rotation, water spray, air supply, vibration, and visible damage.

Apply manufacturer instructions to handpiece cleaning, lubrication, purging, packaging, and sterilization.

Select an appropriate handpiece, attachment, and rotary instrument for a basic clinical task.

Recognize common handpiece problems and choose whether to correct, reprocess, remove from service, or report the equipment.

Differentiate cleaning, sanitizing, disinfection, antisepsis, and sterilization.

Explain how standard precautions interrupt links in the chain of infection in a dental setting.

Select appropriate hand hygiene and personal protective equipment for common dental-assisting tasks.

Classify reusable dental items as critical, semicritical, or noncritical based on how they contact the patient.

Choose cleaning, disinfection, or sterilization for an item based on its infection-risk classification.

Differentiate low-level and intermediate-level surface disinfectants by intended use.

Use label directions to determine a disinfectant's dilution, application method, contact time, and safety precautions.

Sequence removal and replacement of surface barriers without contaminating cleaned areas.

Perform the ordered steps of an operatory turnover while maintaining clean-to-dirty separation.

Respond safely to a contaminated surface, torn barrier, spill, or break in aseptic technique.

Map the one-way workflow from receiving contaminated instruments through cleaning, packaging, sterilization, storage, and distribution.

Transport contaminated instruments and sharps to the processing area using appropriate containment and personal protective equipment.

Compare manual cleaning, ultrasonic cleaning, and automated instrument washing by method, advantages, and safety requirements.

Inspect cleaned instruments and prepare hinged or multipart items for packaging and sterilization.

Select and seal an appropriate sterilization pouch, wrap, or cassette without overloading it.

Place internal and external chemical indicators correctly and interpret their purpose.

Compare steam autoclaves, dry-heat sterilizers, and unsaturated chemical-vapour sterilizers by operating principle, compatible items, advantages, and limitations.

Load a sterilizer to permit circulation and avoid package damage, following the manufacturer's instructions.

Differentiate mechanical, chemical, and biological monitoring of sterilization cycles.

Interpret sterilizer records and indicator results to determine whether a load may be released.

Store and handle sterile packages in a way that preserves package integrity.

Respond to a failed indicator, interrupted cycle, wet package, torn package, or suspected sterilization failure.

Select the correct bur, shank, handpiece, and attachment from a mixed set for a stated basic task.

Identify safety, ergonomic, and infection-control errors in a simulated chairside setup.

Sequence a complete basic assisting scenario from operatory preparation through instrument processing and operatory turnover.

Complete a mixed written self-assessment and classify each error by topic for targeted review.

Use a timed verbal checklist to explain handpiece setup, bur handling, disinfection, and sterilizer monitoring during a mock practical station.
