Evaluation of Apical Leakage After Root Canal Obturation with Glass Ionomer, Resin, and Zinc Oxide Eugenol Sealers Combined with Thermafil

“…The absence of microleakage contributes to successful root canal treatment. Therefore, adequate sealing by the root canal sealer is required to entomb persistent microorganisms remaining in the dentine tubules or in the complex root canal anatomy and those that are not removed by the mechanical and chemical preparation [ 26 ]. Although no current sealers effectively seal the entire root canal system, many investigators have used microleakage studies with dye penetration to try to find the best sealers that do not shrink after root canal treatment [ 1 , 27 ].…”

Influence of chelating solutions on tubular dentin sealer penetration: A systematic review with network meta‐analysis

“…In general, maximum penetration of the sealer is measured by a line from the canal wall up to the dentin outer limit (48,49). The measurement of maximum penetration of the sealer was a unique parameter evaluated by Thota et al (12) and Sreedev et al (31). It has been argued that this type of analysis is not representative as the sealer penetration is not homogenous along the canal (5).…”

“…The analysis of the 12 studies resulted in a total sample of 441 teeth/roots. Exclusively considering the groups used in this systematic review, most of the teeth were mandibular premolars (311 teeth) (3,12,21,(27)(28)(29)(30)(31). Seven different chelating solutions (experimental groups) were reported in the studies: 0.2% chitosan, 10% citric acid, 17% ethylenediaminetetraacetic acid (EDTA), 7% maleic acid, MTAD, QMix and tubulicid.…”

Influence of the use of chelating agents as final irrigant on the push‐out bond strength of epoxy resin‐based root canal sealers: A systematic review

“…The sealer penetration into the dentinal tubules is a desirable property because it reduces the contact surface between gutta‐percha and root dentin. The elimination of any space between the filling and the canal wall helps to avoid displacement of the filling material during subsequent manipulation (2). Despite the release of many endodontic sealers, such as bioceramic‐based material, the epoxy resin‐based sealers are considered the gold‐standard class of sealers in endodontics (11).…”

“…The smear layer, formed on the surface of the root canal walls after shaping procedures, is composed of inorganic and organic components, such as vital or necrotic pulp tissue, odontoblastic processes, microorganisms and dentinal debris (1,2). The most commonly used protocol for removing the smear layer from root canal walls is the sequential use of sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) (3,4).…”
