The aim of root canal obturation is to seal the root canal space and prevent microleakage, which in turn will lead to treatment failure. Root canal obturation has been done using a solid cone which can be either unmodified or modified by heat and in combination to a sealer. These techniques aim to achieve an hermetic seal. The hydraulic sealers, unlike the conventional ones, interact with the dentine and tissue fluids. They are not dimensionally stable but are highly antimicrobial. Furthermore, canal preparation techniques have advanced considerably with the creation of greater taper canals to which well-sized gutta-percha can be fit. Modified gutta-percha cones with bioceramic coating are also available. The use of well fitting cones, which can be bioceramically coated together with the use of a highly antimicrobial hydraulic sealer that bonds to dentine and does not deteriorate in contact with moisture, can lead to a successful singe cone obturation technique. This technique is easy and fast, and aims at a biological seal and can lead to better acceptance by general dental practitioners.
