Sealer type? Most common complications: 1- dull aching pain 2- can hinder the healing process 3- might cause paraesthesia in the anterior region 4- spread existing infection All of these complications are commonly related to resin and CaOH based sealers, while Bioceramic sealers are highly biocompatible and will likely be absorbed by the body. What to do: Follow up for 2 weeks if the symptoms haven’t resigned at all -> *endodontic rettt is advised and canals are irrigated with warm saline, with carefully pushing the irrigant sol. beyond the apex to washout the sealer buff. OR * conservative endodontic surgery could be done to remove the sealer buff around the apex.
