Abstract: Longitudinal co-site optical microscopy study on the chelating ability of etidronate and EDTA using a comparative single-tooth model AbstractIn the present study the smear layer dissolution kinetics of 18% etidronate (HEBP), 9% HEBP, and 17% ethylenediaminetetraacetic acid (EDTA) on human dentin were quantitatively and longitudinally analyzed by using a single-tooth comparative model. Coronal dentin disks were prepared from 3 maxillary human molars. A standardized smear layer was produced on the pulpal side of… Show more

“…Further, a lower concentration of etidronic acid (9%) was utilized, since the demineralization kinetics promoted by both 9% and 18% etidronic acid have been shown to be similar. 25 Compared with the present results obtained using chelating solutions, significantly lower bond strength values were achieved in the NaOCl-treated (control) specimens. This finding strongly suggests that the presence of smear layer has a negative impact on the adhesion of iRoot SP and AH Plus.…”

“…25,26 Here, in both iRoot SP and AH Plus groups, final irrigation with 9% etidronic acid resulted in slightly higher bond strength values than those achieved with 17% EDTA and 1% PAA irrigation. Despite some differences in the irrigation protocols, this finding is in agreement with a recent study, 27 which showed an improvement in the bond strength of AH Plus when a chelating irrigation protocol involving a mixture of 18% etidronic acid and 5% NaOCl was used in the instrumentation phase.…”

“…However, additional studies are needed to determine whether this solution improves or shortens the duration of endodontic irrigation. Demineralization with 9% or 18% HEBP is slower than that with 17% EDTA (35).…”

“…Alternativa como o EDTA tem sido recomendada, pois foi verificado que essa substân-cia, amplamente usada como um agente quelante na Endodontia, reage com os íons de cálcio da dentina removendo-os 10 . Além disso, estudos [41][42][43] , têm demonstrado que o EDTA realiza a descalcificação mais rápida e de forma mais eficaz, independente do pH e do intervalo de tempo, quando comparado com outras soluções, tais como o ácido cítrico e o ácido ortofosfórico.…”
