Single sitting rct usually done in single sitting. Single sitting RCT is only done in those cases where there is no abscess in tooth . Or the tooth structure is not compromised. No periapical lesion present . Single sitting RCT are less time taking as compare to traditional RCT but the success rate is more in traditional RCT or multiple sitting RCT as compare to single sitting RCT.

single sitting R CT s are only preferred when the pain is acute. A long standing case needs more time to heal .

Single sitting RCT is usually done in single rooted tooth and also done where there is no acute infection. It is not preferred by many dentist as sometimes the thorough cleaning done in RCT procedure requires more than one sitting. This differs from case to case though. It is possible only in specific cases as all the cases differ in the amount of infection persisting at that moment.

Chronic cases or cases with large periapical lesions need multiple sitting RCT. It depends on your case which RCT is to be done.

Single sitting root canal done for no acute periapical infection , but requires intentional root canal treatment for aesthetics

Hie dear...dear single sitting rct is preferred in acute infection cases or periapical infection cases ...it is not done in all cases...i usually preferred multiple sitting rct ...in multiple sitting there is no chance of remaining of any infection....

In my opinion I prefer doing single sitting RCTs only. And there are conditions such as pus discharge, periapical lesions where we contraindicate single sitting RCT. I depends on the tooth and its condition.

Hi! Sittings depends on assessment of how successful the case will be. If the infection in the concerned tooth is less then single sitting RCT is done. If infection is more or pain persits- then to let it resolve multiple sitting is opted. Single sitting RCT - the whole procedure from opening the root part through the crown , removing the infected pulp(nerve), cleaning the root canal and finally filling it with a material which is biocompatible and helps ceasing the bacterial growth- all these are done in a single same sitting.
