Uso dos sistemas reciprocantes Reciproc® e Wave One® em Endodontia: revisão de literatura

Revisión de desobturación de gutapercha con limas manuales, Xilol y Reciproc

“…Xylol dissolves slowly, allowing for the controlled removal of gutta-percha (13) . Therefore, it is recommended to use a single drop to avoid harming the patient (17,24) . Xylol softens the guttapercha and decreases the potential resistance of the material to its removal (22,25) .…”

“…However, Khalilac et al (32) found no significant differences between rotary and manual instruments for removal procedures . The advent of alternating systems with a single instrument has simplified retreatment and decreased the time needed: removal with reciprocating instruments is faster, thus reducing the stress of the patient and the operator (17,19,33) . The reciprocating, alternating or oscillatory movement, represented by Reciproc (VDW, Munich, Germany) is a system with a single-use single file (34) .…”

“…However, this instrument tended to break because of cyclic stress, and it was necessary to seal the canal before applying the technique. However, it opened up a promising path for reciprocating motion (17,35,(38)(39) . In 2010, Denstplay launches the VDW Reciproc System (VDW, Munich, Germany) and two files operated with oscillatory movements like Reciproc and Wave appear, thus revolutionizing the endodontics industry based on the concepts developed by Roane and Yared (35,(38)(39) .…”

“…Nonsurgical endodontic retreatment is performed to remove material from the root canal space in order to correct deficiencies or repair pathological or iatrogenic defects, followed by cleaning, shaping and three-dimensional obturation (6,9,15) . When removing filling material, dentin debris, microorganisms, microorganisms or irri-gation solution by-products may be extruded from the root canal area to the periradicular tissues, causing an inflammatory reaction known as flare-up (16)(17) . This reaction causes postoperative pain and edema and delays periapical healing.…”

“…All retreatments leave gutta-percha and sealant debris on the root canals after re-instrumentation. Although it is not possible to fully remove the filling material, it is necessary to remove as much debris as possible to help clean and disinfect the root canal (17) . The aim of this review is to report a series of in vitro studies of nonsurgical retreatment with manual files, xylol and Reciproc, with a focus on current concepts and the importance of the right diagnosis and treatment.…”
