“…All of these properties can be compared with Calcium Hydroxide properties [2][3][4][5][6][7][8][9]. However, Calcium Hydroxide antimicrobial activity is mainly due to alkaline potential [4], while extract presents acidogenic potential [11], so the action path differs between the two substances.…”

“…They can also be performed as a result of asymptomatic cases, but in any case, the infection may be present in the root canal system and or the apical region [3]. The suitable chemical-mechanical preparation as well as the use of intracanal medication eliminates infection, prevents recontamination [3][4][5], and may also prevent or reduce periapical inflammation through biocompatibility [6,7].…”

“…Por isso, a falta de escoamento prejudica a eficácia da obturação endodôntica 11,12 . No entanto, materiais com fluidez exagerada podem, durante a obturação endodôntica, extravasar para os tecidos periapicais, danificando-os.…”

“…Para a avaliação do escoamento, Bernardes et al 12 . A alta fluidez do MTA Fillapex ® pode comprometer seu desempenho clínico, pois aumenta a chance de seu extravasamento durante a obturação, o que pode acarretar dor intensa no pós-operatório, uma vez que, em recentes estudos biológicos, o MTA Fillapex ® apresentou maior irritação em culturas de células 14 nas primeiras cinco semanas e moderada reação inflamatória nos primeiros sete dias em tecido conjuntivo 15 .…”

Na endodontia, o conhecimento das propriedades físi-cas dos cimentos endodônticos faz-se necessário para IntroduçãoA escolha do cimento obturador é uma etapa crí-tica durante a fase de obturação dos canais radiculares, sendo o conhecimento de suas características de fundamental importância. Um cimento endodôn-tico ideal deve apresentar, entre outras propriedades, qualidades antissépticas permanentes, baixa viscosidade, bom escoamento, biocompatibilidade, baixa solubilidade, pH alcalino, estabilidade dimensional, tempo de trabalho adequado, radiopacidade, atividade bacteriostática e adesividade, além de não manchar as estruturas dentárias 1 .A propriedade de escoamento de um cimento obturador consiste na sua capacidade de penetrar em irregularidades, ramificações do sistema de canais radiculares e nos túbulos dentinários. Quanto maior a fluidez do material, maior será sua capacidade de penetração; no entanto, também será maior a chance de ocorrer extravasamento do material e, consequentemente, proporcionar danos ao tecido periapical 2 . O tempo de presa do cimento é outro parâmetro importante, pois, com base nele, é possível calcular o intervalo de tempo disponível para a obturação dos canais radiculares. Essa propriedade pode sofrer interferência de fatores como temperatura, relação entre pó e líquido, granulometria, meio ambiente e pH. De acordo com Alan et al. 3, esse tempo não deve ser longo a ponto de prejudicar a conduta clínica,

“…Endodontic treatment aimed to restore the normality of apical and periapical tissues [1][2][3][4] through a root canal system deep cleaning and disinfection, to control pathogenic microorganisms and the complete three-dimensional sealing using root canal sealers [5][6][7]. To achieve this goal, irrigation and aspiration of the root canal system, coupled with instrumentation, composes an important stage of radical endodontic treatment, the chemical mechanical preparation.…”

The aim of this study was to evaluate the ethanolic extract of Psidium cattleianum biocompatibility by structural and functional cell viability maintenance. Cell viability was analyzed after 1 h, 3 h, 6 h, 10 h and 24 h of incubation by Exclusion Method with trypan blue and MTT assay, using human mononuclear cells (PBMC) and human periodontal ligament (PDL) cells in culture. Positive control used was RPMI cell culture medium and negative control was ethanol 80%. The obtained data were subjected to statistical analysis at a significance level of 5%. By trypan blue assay, ethanolic extract presented a homogeneous performance of PBMC from the 1 h, with average viability between 30 and 50% (p>0.05). By MTT assay, the results showed the efficacy of the ethanolic extract of Psidium cattleianum in maintaining the functional viability of the periodontal ligament cells to 10 h (p>0.05), presenting values greater than the RPMI control. In both methods, it can be observed that the extract properties can neutralize the cytotoxic effect of its diluent ethanol 80%, which showed average viability nearly zero (p <0.05). Thus, biocompatibility by structural and functional cell viability maintenance was considered acceptable to ethanolic extract of Psidium cattleianum and further studies should be performed to indicate its use as an alternative to irrigation solution traditionally used in everyday practice.
