Which tooth is primarily used for cutting and shearing food?
Premolar
Canine
Incisor
Molar
Incisors have thin, sharp edges designed for cutting and shearing food. Canines are pointed for tearing, while premolars and molars grind food.
What is the primary function of the dental mouth mirror?
Applying fluoride
Mixing dental cement
Indirect vision
Direct suction
The mouth mirror allows the dentist to see areas of the mouth not visible directly, known as indirect vision. It also aids in retraction and illumination.
Where is the transfer zone located in four-handed dentistry?
Above the patient's chest
Inside the dental unit tray
Beside the operatory light switch
At the 12 o'clock position
The transfer zone is the area above the patient's chest where instruments are exchanged. This positioning maintains ergonomics and efficient workflow.
Which sterilization method uses saturated steam under pressure to kill all microorganisms including spores?
Dry heat oven
Glass bead sterilizer
Autoclave (steam under pressure)
Alcohol wipe
An autoclave uses saturated steam under pressure to achieve temperatures that kill all microorganisms and spores. Dry heat and alcohol are less effective against spores.
Which of these is an open-ended question useful for assessing patient discomfort?
Is your tooth hurting right now?
Can you describe any discomfort you're feeling?
Do you feel any pain here?
Are you uncomfortable?
Open-ended questions invite detailed responses and help the assistant understand the patient's experience. Closed questions yield yes/no answers and limit information.
Which tooth numbering system uses numbers 1 - 32 for permanent teeth?
Universal Numbering System
Hader Notation System
Palmer Notation System
FDI Two-Digit System
The Universal system labels permanent teeth from 1 to 32. The Palmer system uses quadrant symbols, and the FDI uses two-digit codes.
Which instrument is primarily used to measure periodontal pocket depths?
Scaler
Curette
Periodontal probe
Explorer
A periodontal probe has millimeter markings for measuring pocket depths around teeth. Explorers detect decay, and scalers remove calculus.
Which evacuation device is used to remove large volumes of fluid quickly during a procedure?
High-volume evacuator
Saliva ejector
Air-water syringe
Dry-angle applicator
The high-volume evacuator removes large volumes of saliva and debris quickly. The saliva ejector is for low-volume fluid removal.
How often should biological spore testing be performed on an autoclave?
Weekly
Monthly
Daily
Once per shift
Biological spore tests verify autoclave efficacy and should be run weekly. Daily indicators monitor temperature, but spores require weekly testing.
Which communication approach best reassures an anxious adult patient before treatment?
Ignore their expressed fears
Use complex dental jargon
Rush to begin the procedure
Provide a clear, step-by-step explanation
Clear, simple explanations build trust and reduce anxiety. Jargon confuses patients, and ignoring fears can increase stress.
What is the correct order for setting up a basic tray for an amalgam restoration?
Explorer â†' Mirror â†' Condenser â†' Cotton Pliers
Cotton Pliers â†' Mirror â†' Explorer â†' Condenser
Condenser â†' Explorer â†' Cotton Pliers â†' Mirror
Mirror â†' Explorer â†' Cotton Pliers â†' Condenser
A basic tray setup begins with inspection tools (mirror, explorer), followed by cotton pliers, and then restorative instruments like the condenser.
In FDI notation, tooth 1.6 refers to which tooth?
Maxillary right first molar
Mandibular right first molar
Maxillary left first premolar
Mandibular left first premolar
In the FDI system, the first digit (1) indicates the upper right quadrant, and the second digit (6) indicates the first molar.
Which instrument is designed to carry and dispense amalgam into a cavity preparation?
Explorer
Burnisher
Amalgam carrier
Periodontal probe
The amalgam carrier has wells to transport mixed amalgam into the cavity. Burnishers finish restorations, and explorers detect decay.
Where should the saliva ejector tip be positioned during a posterior restoration?
On the lower lip
Distal to the tooth being treated
Inside the cheek fold
Directly against the tongue
Positioning the tip just distal to the working tooth keeps the field dry without injuring soft tissues. Direct contact can cause discomfort.
Which disinfectant category does an iodophor belong to?
Intermediate-level disinfectant
Low-level disinfectant
Sterilant
High-level disinfectant
Iodophors are intermediate-level disinfectants effective against bacteria, viruses, and some spores. High-level disinfectants include glutaraldehyde.
Which cusp is located on the mesiolingual aspect of the maxillary first molar?
Metacone
Paracone
Hypocone
Protocone
The mesiolingual cusp of the maxillary first molar is called the protocone. The paracone is mesiobuccal, metacone is distobuccal, and hypocone is distolingual.
Which Gracey curette is area-specific for mesial surfaces of all teeth?
1/2
13/14
11/12
5/6
Gracey 1/2 curettes are designed specifically for mesial surfaces of anterior and posterior teeth. Other Gracey instruments target different areas.
During a crown preparation procedure, which assistant task is most critical in four-handed dentistry?
Carving the provisional crown
Selecting the correct bur
Adjusting the dental light
Managing high-volume evacuation
Effective management of the high-volume evacuator maintains a clear field and patient safety. The dentist selects and uses the bur; the assistant supports suction.
A 7-year-old child becomes anxious during treatment. Which communication strategy is most effective?
Offer praise and distract with a favorite toy
Raise your voice to gain attention
Tell the child to be quiet
Ignore the child's behavior
Positive reinforcement and distraction help reduce pediatric anxiety. Ignoring or scolding a child can increase fear and resistance.
Which sequence correctly represents the order of steps in a direct composite restoration?
Etch â†' Light-cure â†' Apply bonding agent â†' Rinse and dry
Etch â†' Rinse and dry â†' Apply bonding agent â†' Light-cure
Apply bonding agent â†' Etch â†' Rinse and dry â†' Light-cure
Rinse and dry â†' Etch â†' Light-cure â†' Apply bonding agent
The proper workflow is to etch enamel and dentin, rinse and dry, apply the bonding agent, and then light-cure before placing composite. This sequence ensures optimal adhesion.
