How Root Canal Treatment or RCT procedure done?
Diagnostic and preparation: The tooth is clinically diagnosed & investigated with x-ray & short course of Antibiotic is given.
Root Canal Treatment procedure is done by drilling out the outer enamel & dentin part of the tooth under local anaesthesia. First, the Dentist reached the pulp chamber, where the infected or inflamed pulp is present. The next step is an exploration of a root canal, removal of the remaining pulp tissue and infected tissue. The infected pulp is then taken out with the help of long needle-shaped drills called files, Remears, Protaper files, K-flex, Headstroem ( H-files) etc.
After successful removal of the pulp, Canal shaping done, then Pulp chamber is irrigated with a different irrigating solution like Sodium Hypochlorite, EDTA etc. Then the root canal is disinfected with the help of intracanal medicaments with Calcium Hydroxide or Chlorhexidine Digluconate or Sodium Hypochlorite etc. The disinfection procedure is done by using a plastic pipette or a syringe. Finally, filling (obturation) of a root canal is done with an inert filling material called gutta percha.
Root canal treatment is commonly done in 3-4 days appointment, depending upon tooth infection. After successful treatment of RCT you should use tooth crown, because after RCT tooth becomes brittle & if you won’t use crown tooth may fracture. After completing the RCT regular maintains- cleaning, scaling is also very important.
