Root Canal Obturation Quiz

What is the main aim of root canal obturation?

• To provide a 2 dimensional seal of root canal space

• To prevent ingress of bacteria and body fluids into root canal space

• To encourage bacterial growth within the root canal

• To create an environment for recurrent infection

What is the timing of obturation based on patient symptoms?

• When the patient has tenderness to percussion

• When the patient has no symptoms

• When the patient has sensitivity to percussion

• When the patient has irreversible pulpitis

What is the purpose of using a sealer in root canal obturation?

• To provide color to the obturation material

• To bond between gutta-percha and root canal walls

• To increase the risk of vertical root fracture

• To create voids and spaces between cones

What is the main advantage of the lateral compaction obturation technique?

• It can be used with routine clinical situations

• It increases the risk of vertical root fracture

• It provides excellent sealing of the canal apically and laterally

• It is less time-consuming

What is the main disadvantage of the warm vertical compaction obturation technique?

• It provides excellent sealing of the canal apically and laterally

• It may not sufficiently fill the irregularities within the canal

• It is less time-consuming

• It increases the risk of vertical root fracture

What is the main characteristic of an ideal root filling material?

• Easily dissolved in water

• To encourage bacterial growth within the root canal

• To prevent ingress of bacteria and body fluids into root canal space

• To create an environment for recurrent infection

• To avoid recurrent infection

What is the main function of root canal sealers?

• To lubricate and aid the seating of gutta-percha cones

• To increase the risk of vertical root fracture

• To create voids and spaces between cones

• To encourage bacterial growth within the root canal

What is the main advantage of gutta-percha as a root filling material?

• Compatibility and inertness

• Lack of adhesiveness

• Lack of rigidity
