if you clean the canals properly,i.e remove all the remnants from the canal. if

you place only one master cone with no accesory cones,then the case will be

success full.atleat for min 5-7years.

Just wanted to inquire without an apical seal how can a tooth even qualify for

root canal treatment? Can u please confirm if these are author views only

because some authors may not agree with the same idea.How can we be sure what

our examiner believes in regard to such questions where there is a difference of

opinion?

Hi guys

Which of the following is the most critical step in root canal therapy?

Cleaning and shaping.

Obturation.

A hermetic apical seal.

A hermetic coronal seal.

C and D.

Answer: A. Cleaning and shaping.

Historically, many authors have written that obturation is the most important

part of root canal therapy. Recent studies have shown that achieving adequate

chemomechanical debridement is paramount. The most common cause of root canal

failure is inadequately disinfected canal systems. A rubber dam is always

indicated during root canal therapy. Even if a superior obturation is achieved,

all dental work leaks on a microscopic level and residual microorganisms will

eventually cause failure of the endodontic treatment rendered.

A coronal seal has emerged as being more important than the apical seal for long

term success as a failed coronal seal provides easier access for microbial

invasion of the canal system relative to the failed apical seal in most cases.

Even in cases where the endodontic therapy is questionable, a good coronal

restoration has been shown to improve the overall result.
