The first stage of carious cavity preparation:
opening the carious cavity
expansion of the carious cavity
necrectomy
forming a carious cavity
The second stage of carious cavity preparation:
expansion of the carious cavity
enamel edge treatment
disclosure of the carious cavity
forming a carious cavity
The final stage of carious cavity preparation:
enamel edge treatment
disclosure of the carious cavity
expansion of the carious cavity
forming a carious cavity
A dental hard tissue necrectomy should be performed with a bur:
spherical
cylindrical
cone-shaped
reverse cone

cylindrical
spherical
cone-shaped
reverse cone
Cariesimmune zones are located:
on the cusps and vestibular surfaces
on vestibular surfaces and fissures
on fissures and bumps
on the blind alleys
A technique to enhance the retention of cement restorations:
forming additional retention features and undercuts
avoiding the use of an insulating base
incorporating anchor pins
all of the above are correct
A method for improving the retention of cement fillings:
application of parapulpal pins
creating rounded cavity shapes
refusal to apply an insulating pad
application of anchor pins
The bottom of the additional pad shall be located:
1-2 mm below the enamel-dentinous border
within the enamel layer
on the border of the peri-pulpal dentin
any option is possible
Medium caries is differentiated:
Erosion
Acute diffuse pulpitis.
Fournier's tooth
Acute focal pulpitis
Erosion is often accompanied by:
Hyperesthesia
Tripping pains
Self-inflicted pains
Deep carious cavity.
The wedge-shaped defect is localized:
Neck area
On the aproximal surfaces
On the chewing surface
On the cutting edge
When treating superficial caries (grade 1), for a permanent filling use:
Tetric-Ceram
Adhesor
Belacin
Dentin-paste
When treating superficial caries (grade 2), for a permanent filling use:
Herculite
Adhesor
Tenet
Dentin-paste
Superficial caries is differentiated by:
affecting only the enamel layer
chronic fibrous pulpitis.
chronic fibrous periodontitis
deep caries
Remineralization therapy is used when:
Caries in the stain stage
moderate caries
deep caries
Chronic fibrous pulpitis.
Calcium and fluoride ions can be introduced into the enamel demineralization site by:
electrophoresis, applications
infiltration anesthesia
filling a carious cavity
conductive anesthesia
Decreased tooth enamel resistance in pregnancy is caused by:
Toxicosis in the first third of pregnancy
Regular oral hygiene of the mother's mouth
Balanced maternal diet
Delayed labor
When diagnosing superficial caries in the area of natural fissures, dynamic observation (repeated examinations) is allowed:
In 2-3 months
In 2-3 years
In 2-3 weeks
In 2-3 days
Superficial caries can be differentiated with:
Hypoplasia
