BACKGROUND The aim was to compare the efficacy of the passive ultrasonic irrigation PUI and the Xp-endo Finisher (FKG-Dentaire, La-Chaux-de-Fonds, Switzerland) in removing the calcium hydroxide paste from root canals and from the apical third. MATERIAL AND METHODS Sixty-eight root canals of single-rooted teeth were shaped using the BT-Race files (FKG-Dentaire, La-Chaux-de-Fonds, Switzerland)....

Objective To evaluate the effect of passive ultrasonic irrigation or XP-Endo Finisher on post-operative pain in patients with necrotic teeth apical periodontitis using (VAS) scale at 6, 12, 24, 48, 72 hours, and 7 day time intervals.
 Methods Seventy-eight diagnosed mandibular first molar symptomatic were randomly allocated into 1 3 separate groups (n=26); Navitip group (control), group, U...

OBJECTIVE Calcium hydroxide (Ca(OH)2) has been used in endodontics as an intracanal medicament due to its antimicrobial effects and its ability to inactivate bacterial endotoxin. The inability to totally remove this intracanal medicament from the root canal system, however, may interfere with the setting of eugenol-based sealers or inhibit bonding of resin to dentin, thus presenting clinical ch...

Aim: To evaluate the effectiveness of different irrigation solutions and ultrasonic activation of the irrigation solutions on the removal of calcium hydroxide (Ca(OH)2) from the simulated immature root canals after apexification. Materials and methods: One-hundred and one single-rooted teeth were used. The root canals were shaped with ProTaper rotary files up to F5. Simulation of roots with imm...

introduction: the penetration depth of irrigating solutions in dentinal tubules is limited; consequently, bacteria can remain inside dentinal tubules after the cleaning and shaping of the root canal system. therefore, new irrigation systems are required to increase the penetration depth of irrigating solutions in dentinal tubules. methods: a comparative study regarding the penetration depth of ...

New technical and scientific developments have been advocated to promote the success of the endodontic treatment. In addition to rotary and reciprocating systems, irrigating solution agitation has been suggested and passive ultrasonic irrigation (PUI) is the most used. OBJECTIVE To evaluate, in vitro, the effect of ultrasound streaming (US) in the disinfection of flattened root canal systems ...

Smear layer removal in root canal treatment is required to aid the diffusion of intracanal medicament and help sealer penetrate into dentinal tubules. The need for irrigants important facilitate smear canal. Various methods have been proposed some articles, but their application apical third still challenges many clinicians due complexity This study aimed analyze effect temperature passive ultr...
