Bioceramic-Based Root Canal Sealers: A Review

Abstract

Bioceramic-based root canal sealers are considered to be an advantageous technology in endodontics. The aim of this review was to consider laboratory experiments and clinical studies of these sealers. An extensive search of the endodontic literature was made to identify publications related to bioceramic-based root canal sealers. The outcome of laboratory and clinical studies on the biological and physical properties of bioceramic-based sealers along with comparative studies with other sealers was assessed. Several studies were evaluated covering different properties of bioceramic-based sealers including physical properties, biocompatibility, sealing ability, adhesion, solubility, and antibacterial efficacy. Bioceramic-based sealers were found to be biocompatible and comparable to other commercial sealers. The clinical outcomes associated with the use of bioceramic-based root canal sealers are not established in the literature.

Comparison of Apical Leakage in Root Canal Obturation Using Bioceramic and Polydimethylsiloxane Sealer (<i>In Vitro</i>)

“…According to Tronstad et al (2000), tight sealing of the canal space is necessary to maintain satisfactory condition of the periapical tissue [8] [9]. Therefore, the physical properties that need to be observed from a root canal sealer is its ability to adhere with the root canal wall and gutta-percha, the solubility against the body tissue fluid, and its stability after hardened.…”

“…Both sealers have good biocompability characteristics against the body tissue, low solubility, and good flow. Bioceramic sealer is able to diffuse into dentinal tubules to create mechanical interlocking bonds and form a hydroxyapatite-like structure along the mineral infiltration zone [9]. Meanwhile polydimethylsiloxane sealer is able to expand as much as 0.2% after hardened thus making it able to fill the spaces formed by the irregularity of the canal wall.…”

Comparative apical sealing evaluation of two bioceramic endodontic sealers

“…By obtaining the hybrid layer, all communications between the exterior and the radicular canal are eliminated, realising a complete seal of the dentinal wound [24].…”

Novel Bioactive and Therapeutic Root Canal Sealers with Antibacterial and Remineralization Properties

“…Several classes of calcium-phosphate and calcium silicate root canal sealers have been developed. Their major benefits are to produce high pH and calcium and phosphate ion release to promote mineralized tissue formation [70]. Recently, Inorganic fillers were incorporated into polymeric resin matrices and tested for their potential to release high levels of Ca and P ions and strengthen the tooth root structure [54].…”
