“…These studies showed that there was no correlation between bacterial and dye penetration through interim restorations with Ketac Fil (3M ESPE, Seefeld, Germany) with and without stainless steel bands. In another study the sensibility and sealability between bacterial penetration and dye extraction methods of 3 root canal filling materials (lateral condensation, System B, and Thermafil) were compared by using a nondestructive bacterial penetration model (9). Subsequently, only the specimens with no bacterial penetration were submitted to the dye extraction assay.…”

“…Usually, a specific leakage test has been performed aiming to evaluate the sealing ability of several materials or techniques 1,2,6,13,15,16 . Nevertheless, the results obtained from different leakage models on similar specimens have rarely been compared on the same study 21,22,23,24 . Therefore, this paper attempted to provide a comparison between results from two different leakage methods, namely glucose and bacterial penetration, which had not been compared so far.…”

“…It is known that the results obtained from ex vivo studies might not be directly extrapolated to the clinical situation 24 . To solve the problem, many efforts have been done to standardize and validate the leakage tests 8,9 .…”

Introdução: os métodos utilizados para avaliar o selamento apical de materiais obturadores de canais radiculares apresentam algumas limitações e grande variabilidade de resultados pode ser observada. Objetivo: O objetivo deste estudo foi comparar, em modelo de apicificação ex vivo , os resultados dos testes de infiltração bacteriana e de glicose, comunicados em tampões apicais de agregado de trióxido mineral (MTA). Materiais e Métodos: Sessenta segmentos radiculares (12mm) foram divididos aleatoriamente em 2 grupos experimentais (n = 30): G1) MTA; G2) MTA + solução salina tamponada com fosfato intracanal. Metade das responsáveis de cada grupo foi submetido ao teste de infiltração bacteriana com E. faecalispor 70 dias. A outra metade foi submetida ao teste de vazamento de glicose sob pressão (103KPa) por 60 min. Os resultados dos dois testes foram comparados com base no número de corpos de prova que vazamento. Os dados foram obtidos pelo teste de Fisher (p <0,05). Resultados: Não houve diferença entre os testes para os dois grupos importantes (p> 0,05). Conclusão: Os resultados do presente estudo ex vivo demonstraram que não houve diferença entre os métodos de avaliação de vazamento de glicose e bactérias, dentro dos parâmetros do presente estudo e independentemente das limitações.

“…According to Torabinejad et al, the sealing ability of MTA in terms of bacterial leakage depends on its antimicrobial rather than physical properties. However, bacterial leakage studies have employed limited models that did not simulate any of the phenomena occurring in the oral cavity, such as temperature changes, dietary influences, and salivary flow (5,38,39). The protein molecules studied in this experiment are larger than dye molecules and smaller than the majority of bacterial cells.…”

Sealing ability of mineral trioxide aggregate and Portland cement for furcal perforation repair: a protein leakage study

et al. 2009

The purpose of this study was to compare the sealing ability of gray mineral trioxide aggregate (GMTA), white MTA (WMTA), and both white and gray Portland cement as furcation perforation repair materials. A total of 120 human mandibular first molars were used. After root canal obturation and preparation of furcal perforations the specimens were randomly divided into four groups of 25 teeth each. In groups A, B, C, and D furcation perforations were filled with WMTA, GMTA, white Portland cement, and type II Portland cement, respectively. Ten teeth were used as positive controls with no filling materials in the perforations and 10 teeth with complete coverage with two layers of nail varnish were used as negative controls. A protein leakage model utilizing 22% bovine serum albumin (BSA) was used for evaluation. Leakage was noted when color conversion of the protein reagent was observed. The controls behaved as expected. Leakage was found in the samples from group A (WMTA), group B (GMTA), and in the two other groups (white and gray Portland cement). There were no statistically significant differences between GMTA and WMTA or white and gray Portland cement, but significant differences were observed between the MTA groups and the Portland cement groups. It was concluded that Portland cements have better sealing ability than MTA, and can be recommended for repair of furcation perforation if the present results are supported by other in vivo and in vitro studies.
