Question

Answer

What is the primary objective of

endodontic treatment?

The primary objective of endodontic treatment is to

eliminate infection from the root canal system and

to prevent reinfection, thereby preserving the

natural tooth.

Which irrigant is most commonly

used during root canal treatment

for its antimicrobial properties?

Sodium hypochlorite is the most commonly used

irrigant during root canal treatment due to its

eﬀective antimicrobial properties and ability to

dissolve organic tissue.

What is the signiﬁcance of

working length determination in

endodontic practice?

Accurate working length determination ensures

complete cleaning and shaping of the root canal

without damaging periapical tissues, thus improving

treatment success.

Which instrument is typically

used for initial canal negotiation

in endodontics?

A small-sized K-ﬁle or stainless steel hand ﬁle is

typically used for initial canal negotiation to

establish patency and create a glide path.

What is the primary cause of

persistent endodontic failure?

Persistent endodontic failure is most commonly

caused by incomplete removal of bacteria and

necrotic tissue, leading to persistent infection in the

root canal system.

Which obturation technique

provides the best three-

dimensional seal of the root

canal?

The warm vertical compaction technique provides

the best three-dimensional seal by adapting gutta-

percha closely to canal irregularities.

What role does calcium hydroxide

play as an intracanal

medicament?

Calcium hydroxide acts as an antimicrobial agent

and promotes healing by creating an alkaline

environment that inhibits bacterial growth inside

the root canal.

Why is rubber dam isolation

important during endodontic

procedures?

Rubber dam isolation prevents contamination of the

root canal system by saliva and oral bacteria,

enhances visibility, and protects the patient from

ingestion or aspiration of instruments.
