简要总结
Chemo-mechanical debridement of the root canal aims to remove pulpal tissues, microorganisms and their by-products, and debris using endodontic instruments and irrigants. Endodontic irrigant reduces the friction between the instrument and dentin; improves the cutting effectiveness of the files used; dissolves tissue; cools the file and tooth; and, furthermore, it has both a washing effect and an antimicrobial/antibiofilm effect. Irrigants have traditionally been delivered into the root canal space using syringes and metal needles of different sizes and tip designs. Many irrigation devices have been developed with the aim of improving the irrigant delivery throughout the root canal by using ultrasonic or sonic energy and apical negative pressure. One of the important aspects of root canal therapy is to control pain after treatment. Postoperative pain is an unwanted yet unfortunately common sensation after endodontic treatment. The incidence of postoperative pain was reported to range from 3% to 58%. There is no single factor affecting pain after root canal treatment and it may be due to mechanical, chemical and/or microbial injury to the pulp or periradicular tissues. Irrigating solutions or medications can evoke pain by irritating the periradicular tissues. The root canal irrigation method could affect the amount of apically extruded debris or irrigants. Any irrigation delivery system that reduces the risk of extrusion into periapical tissues would help the patient and the clinician because such a system could decrease postoperative discomfort.
Thus, the present clinical trial aims to comparatively evaluate the three irrigation techniques on causing post operative pain in symptomatic irreversible pulpitis/ apical periodontitis following single visit root canal therapy.
