“…In this method, the sealing ability is measured via air bubble movement within a capillary tube (21,55-58), consisting of an obturated canal with its coronal portion connected to a tube filled with water at atmospheric pressure, and its apex connected to a 20-μL glass capillary tube measuring 170 mm in length and with a uniform caliber filled with water. A pressure of 0.1 atm is applied through the coronal part, forcing the water through the empty spaces along the root canal (53).…”

IntroductionIt is very important to obtain a tight seal in obturated root canal, making it necessary to conduct clinical or laboratory studies on the sealability of endodontic materials. Different methodologies have been historically used to assess microleakage of different endodontic materials. The aim of the present study was to comprehensively review different material testing methods used in microleakage studies, their interpretation and importance in endodontic literature.Material and MethodsA systematic search was conducted in Medline, Cochrane, and Web of Science databases. In addition, the reference lists of review articles on the topic were searched. No language restriction was applied. Two independent reviewers screened the article.ResultsMicroleakage is considered the single most important risk factor responsible for apical periodontitis. Dye penetration, dye diffusion, bacterial and endototoxin infiltration, fluid filtration, glucose, caffeine and protein infiltration, radioisotope penetration, animal studies, and electrochemical or 3D evaluation are different methodologies used to assess dental leakage. 91 out of 177 articles in the primary search were included in the study. These methods are very divergent in their viewpoints; that is why their results cannot be easily compared. It is necessary to standardize microleakage detection methods in order to more correctly evaluate the phenomena that are found between the root canal wall and the root canal filling materials.ConclusionsAll the methods are useful if studies are performed strictly with large sample sizes and proper control groups and if the technique can be standardized. Furthermore, more evaluations of the reliability of the methods are strongly recommended. Key words:Dental leakage, review, root canal, material testing methods, data interpretation.

“…Trabalhos avaliando as propriedades do iRoot SP necessárias para uma melhor vedação do canal radicular, o compararam a outros cimentos endodônticos, mostrando que o iRoot SP permitiu maior selamento apical do que o Sealapex, o EndoREZ e o MTA Fillapex. 34,35 Estudos são contraditórios, um menciona não existir diferença significativa entre o iRoot SP e o AH Plus, 34 porém outro aponta que o EndoSequence BC Sealer apresenta maior vedamento do que o AH Plus. 12 Em relação à interferência do smear layer na propriedade de vedamento e resistência de união do BC Sealer, resultados similares foram obtidos, a ausência ou presença do smear layer não interferiu em nenhuma destas propriedades.…”

Objetivo: O objetivo do presente trabalho foi revisar as publicações prévias sobre o EndoSequence BC Sealer com o intuito de avaliar os resultados obtidos por este cimento em relação às suas propriedades biológicas e físico-químicas, analisando-se, assim, de forma mais consistente, diversos âmbitos de sua atuação e possíveis desfechos de seu uso clínico realizar uma revisão de literatura sobre este material. Material e Métodos: Uma busca extensiva na literatura foi realizada para identificação de todos os artigos publicados sobre o cimento EndoSequence BC Sealer, considerando-se estudos que avaliaram suas propriedades biológicas e físico-químicas. A estratégia de busca foi fundamentada no acesso às bases de dados PubMed e Bireme. Resultados: Trinta e dois artigos satisfizeram os critérios de inclusão e foram utilizados na presente revisão. Os artigos demonstraram que o cimento possui radiopacidade, escoamento, solubilidade e alteração dimensional adequadas. Além disso, o cimento possui atividade antimicrobiana e é biocompatível. Conclusão: A avaliação dos trabalhos prévios do EndoSequence BC Sealer permite concluir que o cimento EndoSequence BC Sealer demonstrou performance satisfatória quanto as propriedades necessárias para um material obturador endodôntico.

Clinical applications of BioAggregate in pediatric dentistry: Case reports

View full text Add to dashboard Cite

Introduction Calcium-silicate-based, nanoparticle-sized BioAggregate is produced as an alternative version of mineral trioxide aggregate (MTA). It contains additives such as calcium phosphate and silicon dioxide but does not contain aluminium oxide and bismuth oxide. Studies have shown that BioAggregate's calcium-ion release is better than these qualities in MTA concerning fracture and acid resistance, biocompatibility and sealing ability. Case outline In this paper, we examine eight case reports. These reports describe the long-term results of using BioAggregate in areas such as pulpotomy and root canal treatment in primary and permanent teeth, partial pulpotomy, artificial apical barrier construction of permanent teeth, root resorption repair, and treatment of dens in dente. Conclusion As evidenced by the case reports examined here, BioAggregate can be used as alternative material to MTA in many dental treatments. These reports also show that the biocompatibility, antibacterial properties, hardening when moisture is present, ideal expansion percentage, impermeability, and dentine adhesion features of BioAggregate provide advantages in clinical use.
