Effect of Retreatment Protocols on the Push-Out Bond Strength of Hydraulic Calcium Silicate Cement in Open-Apex Teeth. [PDF]

ScientificWorldJournal
Objectives During retreatment, complete removal of previous obturation materials is essential, as remnants may compromise adhesion. This study evaluated the effect of four retreatment protocols on the push‐out bond strength of RetroMTA (BioMTA, Seoul, Korea), a fast‐setting calcium silicate–based material, used as an apical barrier in teeth with open ...

Cytotoxicity and Mineralization Activity of Calcium Silicate-Based Root Canal Sealers Compared to Conventional Resin-Based Sealer in Human Gingival Fibroblast Cells. [PDF]

Int J Dent, 2023
Background. Root canal obturation is performed by gutta-percha cones and sealer. Therefore, these materials, specially sealers, must be biocompatible.

Bacterial Leakage Testing in Dentistry: A Comprehensive Review on Methods, Models, and Clinical Relevance. [PDF]

Scientifica (Cairo)
Background The marginal gap increases the rate of bacterial leakage and treatment failure; the measurement of the marginal gap is questionable. The literature revealed that when bacteria get trapped within the smear layer, they can multiply and re‐contaminate the root canal system, leading to treatment failure.

Comparison of push-out bond strength of endodontic sealers after root canal drying with different techniques. [PDF]

Clin Exp Dent Res, 2023
Abstract Objectives An ideal endodontic sealer should bond to both dentin and root‐filling material. This study aimed to assess the push‐out bond strength (PBS) of mineral trioxide aggregate (MTA)‐Fillapex, Endoseal MTA, AH26, and Sure‐Seal Root to root dentin after root canal drying with different techniques.

Correlation of Bond Strength and Dentinal Tubule Penetration Evaluation of Four Different Endodontic Sealers: AH Plus, MTA Fillapex, Endoseal MTA, and Endoseal TCS (Maruchi): An In Vitro Study. [PDF]

Int J Dent
Background The sealer’s penetration into dentinal tubules creates a physical barrier that entombs any remaining bacteria and increases the surface contact with the root canal walls. This study aimed to evaluate the dentinal tubule penetration and push‐out bond strength of four sealers and to assess the correlation between penetration depth and bond ...

Comparative Resistance of AH26 and a New Sealer Prototype to a Bacterial Challenge [PDF]

International Journal of Dentistry, 2012
Objective. This study compared the leakage resistance of a New Sealer Prototype (NSP) with a traditional sealer (AH 26) in Resilon-filled roots subjected to a bacterial challenge. Study Design. 41 roots were instrumented to ISO size 50 apically. Group 1 (n = 20) contained Resilon and AH 26 sealer and roots in group 2 (n = 21) contained Resilon and NSP.
