Quiz 1 Flashcards
The holes for the maxillary anterior teeth are punched down _______ from the upper edge of the rubber dam material.
2 inches
It is helpful to stamp or mark the extension in back of the punch plate of the dental dam punch to indicate 1 inch.
The purpose of inverting the dental dam into the gingival sulcus is to:
prevent saliva leakage.
Inverting the dental dam creates a seal to prevent the leakage of saliva.
When removing cotton roll isolation, the dental assistant must wet the cotton roll before removal because:
a dry cotton roll can stick to the lining mucosa and cause injury.
Wetting the cotton roll makes it easier to remove without causing harm.
The HVE is held using a _________ grasp.
pen
The HVE can also be held in the palm grasp.
The two types of tests that the dentist uses to determine whether the inflammatory process has gone into the periapical tissues are ____________ and ___________.
palpation; percussion
These tests help assess the extent of inflammation in the periapical area.
What is pulp fibrosis?
It is the decrease of living cells within the pulp.
Pulp fibrosis can occur due to traumatic injury or in older patients.
Which sign or symptom is uncommon for pulpitis?
Fever
Fever is typically associated with extreme cellulitis.
Which factor can cause pulpal nerve damage?
Physical irritation
Trauma is a common cause, while poor nutrition does not directly damage the pulpal nerve.
What is the most common symptom of pulpal damage?
Pain when occluding
This symptom is a key indicator of pulpal issues.
All of the following are indications for using the saliva ejector except:
removal of solid debris.
The saliva ejector is not powerful enough for solid debris removal.
What would not cause endodontic failure?
Recurrent caries
Other factors include severely curved roots and perforation of the canal.
Which statement is incorrect concerning hand-operated files?
Each file is color-coded according to flexibility of the file.
Each file is actually color-coded according to size.
All of the following are guidelines for using the air-water syringe except:
directing the syringe tip toward the patient’s nose and lips.
This could cause discomfort to the patient.
Which thickness of rubber dam material is most widely used for operative procedures?
Medium
Medium thickness is favored for its handling and isolation capabilities.
Which instrument is used to remove dentin and to smooth and increase the size of the canal?
Reamer file
The Hedstrom file is specifically for final enlargement.
The three most common methods used to isolate a specific area of the mouth include:
cotton rolls, dry angles, and the dental dam.
These methods are essential for effective isolation during procedures.
The piece of dental floss or dental tape that should always be attached to the bow of the dental dam clamp prior to clamp placement is called a(n):
ligature
This serves as a safety measure in case the clamp dislodges.
Which process is used to remove bacteria, necrotic tissue, and organic debris from the root canal?
Debridement
This step is crucial for cleaning the root canal before filling.
When the high-speed handpiece is positioned on the occlusal surface of tooth #3, where would the assistant position the HVE?
Buccal surface of #2
Proper positioning ensures effective suction during procedures.
Which tissues surround the root of the tooth?
Periradicular
This term refers to the tissues surrounding the root.
The high-volume evacuator (HVE) is able to take up water and debris because a _____ volume of air is moved into the vacuum hose at _____ pressure to create a strong suction.
high; low
This combination is essential for effective suction.
The rubber dam may tear or stretch if the holes that are punched in it are too:
close together.
This can lead to leakage and improper fit.
Which radiograph image is taken with the final size files in all canals receiving treatment?
Final instrumentation
This image is crucial for assessing treatment progress.
The ________ is punched as the largest size hole (#5) to accommodate the dental dam clamp that fits on the ________ tooth.
keypunch hole; anchor
This ensures proper placement of the dental dam clamp.
Which of the following is used to absorb solutions and dry the canal?
Paper points
These are used to ensure the canal is dry before filling.
Which vitality test is the least useful?
Heat
A painful response to heat can indicate both reversible and irreversible pulpitis.
Which procedure is most commonly used for vital primary teeth?
Pulpotomy
This procedure preserves the vitality of the remaining pulp.
When the tooth pulp has symptoms of lingering pain, a diagnosis of _______ can be made.
irreversible pulpitis
This condition indicates that the pulp is incapable of healing.
What is the defining characteristic of irreversible pulpitis?
Symptoms of lingering pain and pulp incapable of healing.
Irreversible pulpitis indicates that the pulp cannot recover, often leading to the need for more invasive procedures.
What develops as an inflammatory response to pulpal infection?
Periradicular cyst.
A periradicular cyst is associated with necrosis of the pulp.
What occurs when the pulp is irritated but can still recover?
Reversible pulpitis.
This condition allows for potential treatment to save the pulp by removing the irritant.
What is the cause of a periodontal abscess?
Bacteria entrapped in the periodontal sulcus.
This leads to rapid onset pain, swelling, and tenderness to pressure.
What is used along with the HVE to complete the rinsing process?
Air-water syringe.
The air-water syringe provides convenience and accuracy in rinsing.
How often should an antimicrobial solution be flushed through the evacuation system hoses?
Daily.
Flushing daily prevents microbial growth in the hoses.
What is the dental dam material between the holes of the punched dam called?
Septum.
Insufficient or excessive septum material can cause complications during procedures.
What term most accurately identifies root canal therapy?
Pulpectomy.
A pulpectomy involves the complete removal of the dental pulp.
If a tooth has a necrotic pulp, it will not respond to _______.
heat and cold stimulus.
A necrotic pulp does not elicit responses to thermal stimuli.
When is the dental dam placed in relation to local anesthetic administration?
After.
This ensures visibility during the anesthetic injection and reduces patient discomfort.
Which tests include checking for cold sensitivity?
Thermal sensitivity tests.
These tests utilize ice or dry ice for cold sensitivity assessment.
The isolation of anterior teeth is usually from _______.
canine to canine.
This method typically does not require a dental dam clamp.
What natural rubber material is used to obturate the pulpal canal?
Gutta-percha.
Gutta-percha is specifically designed for sealing the canal after treatment.
The saliva ejector should be placed _______ the tongue on the __________ where the dentist is working.
under; opposite side from.
This placement minimizes items in the operating field.
After use, a plastic HVE tip is _______.
thrown away.
Plastic tips are typically disposable, while stainless steel tips can be sterilized.
Which step in root canal therapy takes place first?
