The patient has no spontaneous pain and responds normally to pulp testing and percussion. However, radiographically, there are some pulpal calcifications but no evidence of resorption, caries, or mechanical pulp exposure. The pulpal diagnosis of this case is:
Asymptomatic irreversible pulpitis
Normal pulp
Reversible pulpitis
Symptomatic Irreversible Pulpitis
The patient complains of pain upon drinking cold drinks, but the pain disappears immediately after the stimulation is over. The tooth response normally to pulp and periapical tests. Radiographically, there is no periapical change but caries can be seen approaching the pulp chamber. What is the likely pulpal diagnosis of this case?
Normal pulp
Reversible pulpitis
Symptomatic Irreversible Pulpitis
Asymptomatic irreversible pulpitis
The patient has no any symptoms and response normally to both pulp and periapical test. However, the radiograph shows the caries extend well into the pulp. So, what is the likely pulpal diagnosis of this case?
Normal pulp
Reversible pulpitis
Symptomatic Irreversible Pulpitis
Asymptomatic irreversible pulpitis
The patient reports spontaneous pain and responses with extreme pain to cold test. Periapical tests give a normal response, and the radiograph also shows normal periapical structure. The pulpal diagnosis of this case would be:
Normal pulp
Reversible pulpitis
Symptomatic Irreversible Pulpitis
Asymptomatic irreversible pulpitis
What is the treatment of asymptomatic irreversible pulpitis?
Pulp capping
Pulpotomy
Pulpectomy
No treatment is required
Cavity and crown preparation should be carried out:

At which speed is it safe to prepare a vital tooth without water?
At 3000 rpm or lower
At 4500 rpm or lower
At 6000 rpm or lower
At 9000 rpm or lower
Why high-torque handpiece should only be used for detail work and to excavate carious soft dentin?
Because it is too slow
Because it leads to bur vibration which may cause internal bleeding of the pulp.
Because it is hard to handle
Because it cannot be used with water spray
Bent burs should be discarded because:?
Burs are not expensive
They may vibrate or rotate eccentrically
They can be fractured during the cavity preparation
They become dull and cannot cut dentin efficiently
Which material should be used for cleansing dentin surface?
Alcohol
Detergent
Water spray
Disinfectant
After cleansing, the dentin surface should be:
Dried thoroughly using a strong air blast
Dried using shorts blasts of air and cotton pellet
Left to dry by itself
Left wet
Base materials are used for two reasons:
To protect the pulp from harmful components in a filling material and from marginal leakage, and to influence the repair processes in the pulp to enhance healing.
Because they are cheaper than filling materials, and they are easily handled
To bond filling materials to the tooth structure, and to protect the pulp from harmful components in those filling materials.
To bond filling materials to the tooth structure, and to influence the repair processes in the pulp to enhance healing.
Two main types of base materials are:
GIC and MTA
MTA and Ca(OH)2
ZOE and Ca(OH)2
ZOE and GIC

To remove the smear layer
To clean out debris and dentinal shavings
To remove necrotic tissue in lateral canals
The effects of mechanical instrument are enhanced by all of the following properties of root canal irrigation except one:?

Which is the most commonly used irrigant?
EDTA
Chlorhexidine
NaOCl
H2O2
Which irrigant has tissue-dissolving ability?
EDTA
Chlorhexidine
NaOCl
H2O2
Which irrigant can remove smear layer?
EDTA
Chlorhexidine
NaOCl
H2O2
In case of NaOCl allergy,
Chlorexidine should be used instead
Saline should be used instead
H2O2 should be used instead
Iodine potassium iodide (IKI) should be used instead
How to improve the tissue-dissolving capacity of NaOCl?
Warm it
Cool it
Lower the concentration
No means to do that
NaOCl is used in concentrations between:
O.1% to 0.5%
0.5% to 6%
6% to 10%
10% to 15%
Which one has the most tissue-dissolving ability?
0.5% NaOCl
2.5% NaOCl
5.25% NaOCl
10% NaOCl
Which one is the less toxic?
0.5% NaOCl
2.5% NaOCl
5.25% NaOCl
10% NaOCl
If lower concentrations of NaOCl are to be used, how should they be used?
They should be used as sparingly as possible.
They should be used in higher volume and in more frequent intervals
They should be used in higher volume but as less frequently as possible.
They should be used in the same manner as those of higher concentrations
Which statement is true about the working time of NaOCl?
NaOCl remains active in the root canal for a very long time, so we can use it as an intracanal medication
NaOCl remains active in the root canal for quite a long time, so there is no need to replenish it during the root canal preparation
NaOCl remains active in the root canal for quite a long time, but we need to replenish it 2 or 3 times during the root canal preparation
NaOCl remains active in the root canal for a very short time, so there is a need to replenish it frequently during the root canal preparation
In endodontics, EDTA is normally used at which concentration?
5%
7%
15%
17%
Which statement is not true about EDTA?
An increase in the temperature of EDTA is desirable.
Longer exposure time to EDTA may cause dentin erosion.
EDTA can remove the smear layers when in direct contact with the root canal wall for less than 1 minute.
EDTA removes the mineralized portion but not the organic portion of the smear layer.
When EDTA is mixed with NaOCl, what will happen?
Brownish-orange precipitate containing parachloroaniline (PCA), which is toxic and mutagenic, is formed.
NaOCl will lose its tissue-dissolving capacity.
White precipitate is formed, and the ability of EDTA to reduce the smear layer is reduced.
Nothing happens
Which of the following statements is true?
Use of NaOCl as the final rinse following EDTA is desirable.
Use of NaOCl as the final rinse following EDTA should probably be avoided as this causes dentin erosion.
Use of NaOCl as the final rinse following EDTA is neither desirable nor prohibited.
Use of NaOCl as the final rinse following EDTA is fine, but chlorhexidine may be better than NaOCl as a final rinse.
The properties of chlorhexidine are as follows except one:
No tissue-dissolving capability
Lower toxicity than NaOCl
No bad smell
No reduced activity in the presence of organic matter
CHX is normally used at concentrations between:
