The usage of calcium hydroxide [Ca(OH)2] as intracanal dressing has been recommended WR LQGXFH DSH[L DWLRQ WR FRQWURO LQWHUQDO DQG H[WHUQDO LQ PPDWRU\ URRW UHDEVRUSWLRQ DQG LQ the therapy of necrotic teeth with periapical lesions2,six,7,17. Nonetheless, failing to entirely eliminate the dressing may possibly interfere with all the seal, adhesion, and penetration of endodontic sealers4,5,14, adversely affecting the clinical efficiency of your sealer and possibly the long-term prognosis of root canal therapy14. The most usually described technique for Ca(OH)two removal would be the use of a master apical H DW ZRUNLQJ OHQJWK FRPELQHG ZLWK WKH XVHof sodium hypochlorite (NaOCl) irrigation and EDTA3,13,20,21,23. Rotary instruments11,12, sonically or ultrasonically-activated tips3,24, and devices which include the CanalBrush22 in conjunction with irrigation have also been encouraged. None of these approaches, nevertheless, have already been able to fully take away Ca(OH)2 from the root canal, especially inside the apical third3,11. The Self-Adjusting File ?SAF (ReDent-Nova, 5D QDQD ,VUDHO LV D KROORZ F\OLQGULFDO H UHFHQWO\ launched inside the industry. Its thin compressible walls are created of a nickel-titanium mesh, enabling its shape to adapt to root canal’s along the crosssection, also as longitudinally. As a result, the SAF will three-dimensionally conform to canals with circular or oval cross-section, permitting maintenance on the original canal shape.

Thirty-six freshly extracted permanent human mandibular incisors with lengths varying from 19 to 21 mm had been chosen following radiographs had been taken in both buccolingual and mesiodistal directions. Exclusion criteria had been: root canals permitting introduction of an instrument exceeding ISO size ten to the apical foramen, teeth presenting apical curvature or two root canals, teeth with prior endodontic therapy and presence of external or internal root reabsorption. A smaller level of composite resin (Z-100, 3M/ ESPE, Salt Lake City, UT, USA) was placed on each root tip to prevent irrigant extrusion in the apical foramen during root ca.
