- What type of pulpitis produces sharp, short-lived pain that resolves quickly after a cold stimulus is removed?
Show answer
Reversible pulpitis.- What type of pulpitis causes lingering pain that continues well after a thermal stimulus is removed?
Show answer
Irreversible pulpitis.- What is the expected pulp test response (cold and electric) in a tooth with pulp necrosis?
Show answer
No response to either cold or electric pulp testing.- Besides lingering pain to cold, what other clinical feature often accompanies symptomatic irreversible pulpitis?
Show answer
Spontaneous pain that occurs without any stimulus.- What are the hallmark signs of an acute apical abscess?
Show answer
Rapid onset of pain, swelling, and tenderness to percussion, often with a necrotic pulp.- What clinical feature distinguishes a chronic apical abscess from an acute one?
Show answer
A draining sinus tract with little or no pain.- What does a positive response to percussion testing indicate?
Show answer
Inflammation of the periodontal ligament (periapical or periodontal involvement).- What key limitation does the electric pulp test have compared to thermal testing?
Show answer

Show answer
Access preparation, canal cleaning and shaping, obturation, then final restoration.- Why is a rubber dam required during root canal treatment?
Show answer
It isolates the tooth, prevents contamination by saliva, and protects the patient from aspirating or swallowing instruments or irrigants.- What two methods are commonly combined to determine working length during root canal treatment?
Show answer
An electronic apex locator and a radiograph with a file in the canal.- What physical principle allows an electronic apex locator to find the apical foramen?
Show answer
It measures electrical impedance (resistance), which changes consistently at the apical constriction.- What is the primary purpose of sodium hypochlorite irrigation during root canal therapy?
Show answer
To dissolve organic tissue and disinfect the canal system.- What is the main purpose of placing calcium hydroxide as an intracanal medicament between appointments?
Show answer
Its high pH provides antibacterial action and helps disinfect the canal system.- What material makes up the core of most root canal filling points?
