Removal efficiency of calcium hydroxide intracanal medicament with RinsEndo system in comparison with passive ultrasonic irrigation, an in vitro study

摘要: Background: Different techniques have been introduced to improve removing the calcium hydroxide intra-canal dressing. The purpose of this study was compare effi ciency passive ultrasonic irrigation (PUI) and RinsEndo system in removal from root canal system. Materials Methods: Access cavities were prepared 50 single-rooted anterior teeth. Cleaning shaping done using Flexmaster rotary up size no. 30, 6%. canals fi lled with injectable (calcipex). After 7 days, retrieved Group 1 ( n = 20), PUI 2 20). In positive control group 5), no performed. negative not any medicament. Following these two systems, teeth split buccolingually into sections every third evaluated under stereomicroscope (×30) analyze residual medicament each segment. Data analyzed Kruskal-Wallis Mann-Whitney tests P < 0.05). Results: There signifi cant difference between at cervical 0.67), middle 0.51) apical 0.75) part canals. Conclusion: None able completely remove Key Words: Calcium hydroxide, system, irrigation,
