Evaluation of apical leakage in root canals filled with different sealers

Abstract: Objective: To evaluate the apical leakage exhibited by different endodontic sealers. Material and Methods:(maxillary molars) and distal roots (mandibular molars) sectioned, standardized and instrumented with Mtwo condensation technique and divided into three groups (n=10), according to the endodontic sealer employed: G1-AH Plus, G2-Fill Canal, G3-MTA Fillapex. All sealer. Gutta-percha points were immersed into sodium hypochlorite for 24 h to achieve disinfection. After the ink for posterior diaphanization and … Show more

“…The results of this study showed that TG sealer which is resin materials was more resistant to bacterial microleakage compared with MTA Fillapex®. These results are similar to the results of both Oliveira et al (28) who evaluated the sealing of MTA Fillapex, Sealapex and AH Plus by fluid movement technique, and they have found that after 180 days AH Plus and Sealapex had the least microleakage, the difference can be attributed to the chemical composition of MTA-based materials. While the results were contradicting to the results of Gomes-Filho et al (41) who concluded that Fillapex® and Sealapex resulted in significantly less microleakage than Endo CPM sealer using dye penetration method.…”

“…Coronal and/or apical leakage enhances the ingress of microorganisms and nutrient that initiate periradicular inflammation and cause failure in endodontic therapy. Adequate marginal sealing between tooth and endodontic restorative material is essential to decrease contamination of the root canal systems during and post endodontic treatment (28)(29)(30) .…”

“…14 No entanto, em outros estudos foi reportada melhor performance para o cimento AH plus em comparaçao ao MTA Fillapex. 15,16 Ao avaliar a associação de um cimento ao MTA, observou-se maior infiltração, mas esta foi compensada pelo "plug'' apical. 17 Neste contexto, existe uma semelhança na composição química entre o cimento de Portland, usado em construção civil e não indicado para uso odontológico, e o MTA.…”

“…O terço cervical apresentou maior penetração de cimento, provavelmente devido à grande pressão lateral aplicada na técnica de condensação lateral ativa, gerando maior penetração de cimento nos túbulos dentinários (OLIVEIRA et al, 2012), e à estrutura anatômica dos canais radiculares, com maior amplitude nas regiões cervical e média (VERTUCCI, 1984(VERTUCCI, , 2005, e maior quantidade de túbulos dentinários e maior volume destes, podendo ser interpretadas como maiores áreas de escape para o cimento endodôntico quando submetido à pressão da técnica obturadora.…”

“…A predominância da distribuição uniforme das linhas de cimento foi observada na análise qualitativa. Isso pode ter ocorrido devido ao fato dos tratamentos terem removido, de forma adequada, a camada de debris e smear (EKIN; ERDEMIR, 2015), bem como a técnica de obturação adotada e seu volume da área obturada terem se mostrado adequados para possibilitar que o cimento endodôntico entrasse em contato com a superfície dentinária intrarradicular (OLIVEIRA et al, 2012).…”
