摘要: In the present study smear layer dissolution kinetics of 18% etidronate (HEBP), 9% HEBP, and 17% ethylenediaminetetraacetic acid (EDTA) on human dentin were quantitatively longitudinally analyzed by using a single-tooth comparative model. Coronal disks prepared from 3 maxillary molars. A standardized was produced pulpal side each disk. The layer-covered surface divided into similar areas. Each these then exposed to 1 irrigants under investigation, whereas others covered with adhesive tape. Co-site image sequences areas investigation obtained after several cumulative demineralization times. Sixteen images area tooth for experimental time at 1000x magnification. An processing analysis sequence measured sets images, providing data fraction thousands tubules over allowing us follow effect chelating substances. Kruskal-Wallis H test Dunn multiple comparison used analyze data. Overall, it can be concluded that promoted both HEBP significantly slower than those EDTA (P < .05). addition, model is advantageous first co-site optical microscopy assessments when different chelator solutions are compared.
