Self-adjusting file cleaning-shaping-irrigation system optimizes the filling of oval-shaped canals with thermoplasticized gutta-percha. Endodontics Endodontics questions that can be asked in the final year BDS exam are listed here according to the value of question and topics of endodontics. With the canal filled with NaOCl, the Endoactivator was used to improve the penetration and disinfecting action of the irrigant. Introduction to rotary & reciprocating systems on the market As with any procedure, equipment and techniques naturally improve in efficiency with time as new instruments are manufactured that overcome the limitations and weaknesses of those that were previously available.
