eugenol, calcium hydroxide, resins, and silicone have been used in combination with GP for root canal obturation.Strong adhesion to the root canal walls and core material is one of a sealer's basic components.Calcium silicate-based bioceramic (BC) sealer, a unique category of high-purity tricalcium silicate sealers, exhibits IntroductIonThe success of nonsurgical endodontic retreatment depends on the complete removal of previous root canal filling material apart from treating the contributing factor for root canal failure and the prevention of recontamination by adequate cleaning and shaping of previously intact areas of the root canal. 1 The prospects of endodontic retreatment, surgical intervention, or tooth extraction may be taken into consideration in situations where an endodontic inflammatory lesion persists or develops.It has been demonstrated that the surgical treatment has a 77% success rate.So, wherever possible, the physician should opt for orthograde root canal retreatment since it may create a favorable environment for periradicular healing without destroying the tooth's structure.Incomplete removal of the filling materials may influence treatment outcomes. 2The presence of root canal obturation materials may prevent persistent microbes from coming into touch with irrigation solutions.A root canal sealer's function is to fill canal abnormalities that the usual solid core substance, gutta-percha (GP), is physically unable to do so with. 1 Numerous sealers such as zinc oxide
