Multi Visit Root Canal Treatment
Multiple-Sitting RCT Procedure
When there is a chronic / long standing infection showing pus accumalation in & around the tooth without or with swelling abscess, RCT require multiple sittings to drain the pus.
Steps in the Multi-sitting RCT procedure:
1 First step is to open the pulp chamber to allow access to the canals.
2 Once open, the infected nerves are removed with the help of special instruments known as files. The canals are flushed with antiseptic solution. Sometimes frank discharge of pus can be seen oozing from canals along with foul odour. This should be flushed out.
3 The root canals are further cleaned & reshaped to free them of all debris.
4 The canals are dried & a temporary dressing is given. Root canal filling is not done.
1 After a couple of days the pulp chamber of the tooth is re-opened. The canals are checked for discharge. If the canals are dry, RC filling is done.
2 If canals are still oozing, the canals are further cleaned & dried & a temporary dressing is given, without doing RC filling.
3 RC filling is done only in a subsequent sitting in which the canal is found dry and free of discharge. The number of sittings in such an RCT procedure can varyfrom case to case, depending on the nature of the infection.
Once the RC filling is done, a temporary filling is done which is then replaced with permanent filling like composite filling. In a chronic case, it may be advisable to wait for 2-3 months before the cap/crown procedure. This period ensures complete healing of the tooth. Periodic Xrays give a good idea of the healing procedure. Once healed, tooth should be capped.
