Dental Nurse 315 Review Book 2025:
Exam Preparation and Revision Topics
Scaler that can be used Supragingivally and Subgingivally, it uses compressed air to work.
A. Hand scaler
B. Sonic scaler
C. Ultrasonic scaler
D. Chisel scaler
Rationale: Ultrasonic scalers use compressed air to vibrate and remove calculus. Hand and
chisel scalers are manual. Sonic scalers use sound waves but lower power.
Preferred method of conserving a tooth with a fractured crown?
A. Extraction
B. Filling
C. Crown
D. Veneer
Rationale: A crown restores full structure and strength. Fillings or veneers are insufficient for
major fractures. Extraction sacrifices the tooth.
It can be used to collect droplets of mercury.
A. Cotton roll
B. Lead foil
C. Rubber dam
D. Gauze
Rationale: Lead foil safely absorbs and contains mercury droplets. Cotton and gauze are
permeable.
Bayonets forceps used for
A. Extracting lower premolars
B. Extracting upper central incisors
C. Extracting upper 3rd molar
D. Extracting lower 3rd molar
Rationale: Bayonet forceps are angled for upper third molars. Other forceps have different
angulations.
It is used for: placing between tooth and gingiva, soaked in astringent to stop bleeding during
restoration or impression.
A. Matrix band
B. Rubber dam
C. Retraction cord
D. Cotton pellet
Rationale: Retraction cord temporarily displaces gingiva for access and hemostasis.
,Medical emergency, patient has a seizure, the dentist can administer...
A. Adrenaline
B. Midazolam
C. Salbutamol
D. Glucose
Rationale: Midazolam is a benzodiazepine that stops seizures.
EPANUTIN is

A. Edentulous
B. Dentate patient
C. Mixed dentition
D. Pediatric
Rationale: “Dentate” means having natural teeth.
Patient with no natural teeth is called

Used to retract soft tissue from bone during surgery
A. Elevator

C. Chisel
,D. Scaler
Rationale: Periosteal elevator separates periosteum from bone surface.
Denture may require a reline to improve fit. Material used:
A. Alginate
B. Composite
C. Zinc oxide and eugenol paste
D. Acrylic resin
Rationale: ZOE paste records functional impression for relining.
Frenectomy may be required
A. After extraction
B. Pre-orthodontic treatment
C. During root canal
D. During scaling
Rationale: Frenectomy removes frenum that interferes with orthodontic movement.
Bur used to prepare a tooth for a veneer
A. Round bur
B. Tapered fissure
C. Flat fissure
D. Inverted cone
Rationale: Flat fissure bur creates a smooth flat surface for veneer bonding.
Final stage of cavity preparation is
A. Outline form
B. Resistance form
C. Shape to ensure retention
D. Depth control
Rationale: Final shaping ensures the restoration stays mechanically retained.
Large spillage of mercury occurs; we inform
A. Dental nurse
B. Local council
C. The Health and Safety Executive
D. The patient
Rationale: The HSE must be notified of hazardous material spills.
Surgical removal of gingiva over a partially erupted tooth (often third molar)
A. Gingivectomy
B. Operculectomy
C. Apicectomy
D. Frenectomy
Rationale: Operculectomy removes inflamed operculum tissue.
, Root and whole tooth removed without soft tissue or bone removal
A. Surgical extraction
B. Simple extraction
C. Apicectomy
D. Curettage
Rationale: Simple extraction uses forceps only.
Smoothing or reshaping bone before dentures
A. Osteotomy
B. Alveolectomy / Alveoplasty
C. Gingivoplasty
D. Apicectomy
Rationale: Alveoplasty reshapes alveolar ridge for denture fit.
Surgical removal of inflamed gum tissue to reshape
A. Operculectomy
B. Gingivectomy / Gingivoplasty
C. Periodontal flap
D. Curettage
Rationale: Gingivectomy removes diseased gingiva for contour correction.
Surgical raising of gingival tissues then sutured back for subgingival cleaning
A. Gingivectomy
B. Periodontal flap surgery
C. Apicectomy
D. Alveolectomy
Rationale: Flap surgery allows access for root debridement.
Partial or complete removal of soft tissue for pathology
A. Gingivectomy
B. Soft tissue biopsy
C. Apicectomy
D. Operculectomy
Rationale: Biopsy obtains tissue for diagnosis.
Roots or whole tooth removed with bone removal
A. Simple extraction
B. Surgical extraction
C. Apicectomy
D. Curettage
Rationale: Surgical extraction involves flap and bone cutting.
Surgical cutting of fibrous tissue under tongue or between centrals
A. Gingivectomy
B. Frenectomy
C. Operculectomy
