An international survey on the use of calcium silicate-based sealers in non-surgical endodontic treatment

Abstract

Objectives: To gain insight on the current clinical usage of Bioceramic root canal sealers (BRCS) by general dental practitioners (GDPs) and endodontic practitioners (EPs) and to determine if BRCS clinical application is in accordance with the best available evidence.Material and methods: An online questionnaire of 18 questions addressing BRCS was proposed to 2335 dentists via a web-based educational forum. Participants were asked about socio-demographic data, clinical practice with BRCS and their motivation for using BRCS. Statistical analysis (Chisquared test or Fisher's exact test) were applied, as appropriate, to assess the association between the variable categories (p-value<0.05). Results:The response rate was 28.91%. Among respondents, 94.8% knew BRCS (EPs more than GDPs, p<0.05) and 51.70% were using BRCS. The primary reason for using BRCS was their believe of its improved properties (87.7%). Among BRCS users, single cone technique (SCT) was the most employed obturation method (63.3%) which was more applied by GDPs (p<0.05); EPs utilized more of the thermoplasticized obturation techniques (p<0.05). A proportion of 38.4% of BRCS users indicated the usage of SCT with BRCS regardless of the root canal anatomy (GDPs more than EPs p<0.05) and 55.6% considered that BRCS may influence their ability to re-establish apical patency during retreatment (GDPs more than EPs p<0.05). Conclusions:This study highlights wide variation in the clinical use of BRCS which is not in accordance with the current literature.Clinical relevance: This inconsistency among EPs and GDPs on BRCS clinical application requires further clarifications to better standardize their use and improve their future evaluation.

Characterization of heat resistant hydraulic sealer for warm vertical obturation

“…The manufacturer recommends the HiFlow for use with warm vertical compaction obturation technique while the Totalfill BC sealer for single cone obturation technique [15]. The effectiveness of the single cone obturation technique with premixed hydraulic sealers has been verified clinically [16] and a recent survey of clinicians has also endorsed the popularity of this technique [17].…”

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

“…Single cone obturation technique has been often regarded as inadequate due to the potential for apical leakage [4], however with the recent advent of hydraulic cement-based endodontic sealer their acceptance has increased because of their increased properties [5]. The possibility of a dissolving process in the apical third may contribute to re-growth of microorganisms and reinfection, however it appears that the solubility of a calcium silicate-based sealer is linked to a positive biological outcome.…”

Main and Accessory Canal Filling Quality of a Premixed Calcium Silicate Endodontic Sealer According to Different Obturation Techniques

“…Based on the reproducible results conducted by independent research groups, we recommend the application of ultrasonic energy to reduce void formation when the SC technique is used. Moreover, an international survey on the use of calcium-silicate-based sealers reported that endodontic specialists utilized more of the thermoplasticized obturation techniques than the SC technique [ 6 ].…”

“…Furthermore, the SC technique is less operator-dependent and potentially reduces the damage to dentinal walls. According to one survey, among calcium silicate sealer users, the SC technique was the most employed obturation method applied by general dental practitioners [ 6 ].…”
