Objective: This study aimed to compare the physicochemical properties of 3 bioceramic sealers (NeoSealer Flo, WellRoot ST, and CeraSeal) with mineral trioxide aggregate-like sealer (MTA Fillapex ), epoxy resin-based sealer (AH Plus Jet), methacrylate resin-based sealer (EndoREZ), and calcium hydroxide/salicylate resin-based sealer (Apexit Plus) in terms of flow, setting time, film thickness, solubility, water absorption, radiopacity, immediate and delayed pH, compressive strength, and dimensional stability. Material and Methods: Flow, setting time, film thickness, and solubility of all sealers were evaluated by International Standards Organization (ISO) 6876:2012, while water absorption and radiopacity values were determined using ISO:4049:2019 and ISO:13116:2014, respectively. Five samples were prepared from sealers for each test (n=5). Data were analyzed with Kruskal-Wallis H test with 5% significance threshold. Results: Flow, setting time, film thickness, and radiopacity values of all canal sealers complied with ISO standards. The solubility of AH Plus Jet, EndoREZ sealers was acceptable, while those of NeoSealer Flo, Well-Root ST, CeraSeal, MTA Fillapex, and Apexit Plus showed greater solubility than recommended. The lowest pH value in freshly mixed samples was observed in EndoREZ sealer. Conclusion: All the sealers complied with ISO 6876:2012 and ISO 13116:2014 standards regarding flow, setting time, film thickness, and radiopacity. MTA Fillapex did not set during its reported working time. The solubility values of AH Plus Jet, EndoREZ pastes were found to comply with ISO 6876:2012 standards, while Apexit Plus and bioceramic sealers exceeded the threshold.

Amaç: Bu çalışma, 3 farklı hidrolik kalsiyum silikat kanal patının (NeoSealer Flo, Well-Root ST ve CeraSeal) fizikokimyasal özelliklerini bir mineral trioksit agregat içeren kanal patı (MTA Fillapex), bir epoksi rezin bazlı kanal patı (AH Plus Jet), bir metakrilat rezin bazlı kanal patı (EndoREZ) ve bir kalsiyum hidroksit/salisilat reçine bazlı kanal patı (Apexit Plus) ile sertleşme zamanı, film kalınlığı, çözünürlük, su emilimi, radyoopasite, sertleşme esnasında ve sonrasındaki pH değerleri, baskı dayanımı ve boyutsal stabilite açısından karşılaştırmayı amaçlamıştır. Gereç ve Yöntemler: Akıcılık, sertleşme süresi, film kalınlığı, çözünürlük Uluslararası Standartlar Teşkilatı [International Standards Organization (ISO)] 6876:2012 ile değerlendirilirken su emme, radyoopasite, erken ve geç pH, basınç dayanımı ve boyutsal stabilite sırasıyla ISO:4049:2019 ve ISO:13116:2014 ile değerlendirildi. Her bir test için beşer örnek hazırlandı (n=5). Veriler %5 anlamlılık eşiği ile Kruskal-Wallis H testi ile istatistiksel olarak analiz edildi. Bulgular: Tüm kanal patlarının akıcılık, sertleşme süresi, film kalınlığı ve radyopaklık değerleri ISO standartlarına uygundu. AH Plus Jet, EndoREZ kanal patlarının çözünürlüğü kabul edilebilir düzeydeyken, NeoSealer Flo, Well-Root ST, CeraSeal, MTA Fillapex ve Apexit Plus arzu edilenden daha yüksek çözünürlük göstermiştir. Yeni karıştırılmış örneklerde en düşük pH değeri EndoREZ için bulundu. Sonuç: Bütün kanal patları akıcılık, sertleşme süresi, film kalınlığı ve radyoopasite açısından ISO 6876:2012 ve ISO 13116:2014 standartlarına uygun bulunmuştur. MTA Fillapex belirtilen sertleşme süresinde sertleşme göstermemiştir. AH Plus Jet ve EndoREZ patlarının çözünürlük değerleri ISO 6876:2012 standardına uygun bulunurken, Apexit Plus ve biyoseramik patlar standartta belirtilen eşiği aşmıştır.
