Outcome of Root Canal Treatments Using a New Calcium Silicate Root Canal Sealer: A Non-Randomized Clinical Trial

“…Current evidence is lacking with modern hydraulic cement. However, several studies proved the high hermetic seal of calcium silicate cements, encouraging their use to create apical plugs as sole obturation material or in conjunction with gutta-percha [6,21].…”

“…In the single cone technique, the root canal is generally obturated with a fitted cone that best matches the shape (taper and apical gauge) of the last rotary instrument used in combination with large quantity of sealer [6].…”

Effect of obturation technique using a new bioceramic sealer on the presence of voids in flattened root canals

“…17 This filling technique uses a gutta-percha cone with a diameter similar to that of the last NiTi instrument used in preparing root canals. 1,16 The single-cone technique was found to be similar to Thermafil and System B thermoplastic techniques in straight canals. 18 In addition, it showed marginal adaptation at the sealer/dentin interface similar to that of the thermoplastic technique in mesial root canals of mandibular molars.…”

“…4 However, the thermoplastic filling technique has shown a higher risk of filling material extrusion than the cold gutta-percha technique. 15 The single-cone technique is frequently used for filling root canals, 1,5,16,17 because of its simplicity and speed, 16 and also because it is less operator-dependent. 17 This filling technique uses a gutta-percha cone with a diameter similar to that of the last NiTi instrument used in preparing root canals.…”

Physico‐chemical investigation of endodontic sealers exposed to simulated intracanal heat application: epoxy resins and zinc oxide–eugenols

“…Temperatures of a maximum of 19.1 °C above body temperature were found in the root canal sealer (Donnermeyer et al ), and it is reasonable to assume that this relatively low temperature increase was due to an immediate dissipation of the temperature of the heat carrier or the pre‐heated gutta‐percha. Taking these recent findings into account, the fundamental premise of several studies conducted on the effects of heat on root canal sealers should be reconsidered as the studies heated the sealers mainly in ovens to 100 °C (Camilleri , Heran et al ), 140 °C (Qu et al ) or even 250 °C (Atmeh & AlShwaimi ) based on how the temperature of the System B Heat Plugger is interpreted. The root canal sealer specimens have been heated for 1 min (Camilleri , Atmeh & AlShwaimi ), 10 min or even as long as 4.6 h (Qu et al ).…”
