Indiana University-Purdue University Indianapolis (IUPUI) / This in-vitro, prospective, randomized study microscopically compared the debridement efficacy of passive ultrasonic irrigation (PUI) using the Ultrasonic Bypass System and different irrigating protocols. Eighty extracted maxillary anterior teeth were randomly assigned to four groups. Teeth were instrumented using EndoSequence rotary instrument system and treated with passive ultrasonic irrigation with different irrigating regimens for one minute. Group one (control) was treated with hand/rotary instrumentation. Group two was treated with hand/rotary instrumentation followed by a one-minute PUI using the Ultrasonic Bypass System with 6.0-percent NaOCl. Group three was treated with hand/rotary instrumentation followed by a one-minute PUI using the Ultrasonic Bypass System with 17-percent EDTA. Group four was treated with hand/rotary instrumentation followed by a one-minute PUI using the Ultrasonic Bypass System with 30 seconds of 6.0-percent NaOCl and 30 seconds of 17-percent EDTA. Teeth were sectioned longitudinally and each half was divided into three equal parts from the anatomic apex. The half with the most visible part of the apex was used for SEM evaluation. A scoring system for debris and smear layer removal was used. Statistical analysis was performed using a Kruskal-Wallis test, which determines if there are any differences among the four groups. Following this test, a Wilcoxon Rank Sum test was used to compare each pair of groups. The addition of a one-minute PUI with the Ultrasonic Bypass System significantly enhanced the removal of smear layer when compared with the hand/rotary instrumentation with conventional irrigating solutions. The Ultrasonic Bypass System when used with the combination of 6.0-percent NaOCl and 17-percent EDTA after hand/rotary instrumentation significantly removed smear layer at the coronal, middle, and apical areas of a tooth when compared with all other groups. A one-minute PUI with the Ultrasonic Bypass System combined with NaOCl and EDTA is significantly better in smear removal and ultimately will result cleaner canal wall.

Title Comparison between the effectiveness of extracorporeal shockwave therapy (ESWT) and the surgical approach in the treatment of the rotator cuff tendinopathy. Objective The main goal of this research work is comparing the effectiveness of extracorporeal shock wave therapy and the surgical intervention (arthroscopic approach) in the treatment of calcific rotator cuff tendinopathy depending on the outcome measures of the Constant-Murley Score (CMS), and the Visual Analogue Scale (VAS) from the recent scientific publications. Methodology This thesis is systemic (literature) review. The studies which recruited in this research were randomized controlled trials, prospective studies, and retrospective case series studies which written in English language form, and published between the year 2000 to the year 2018. The studies were retrieved from following databases: EMBASE, PubMed, CINAHL, Medline, SpringerLink, ProQuest using different integrations of the key words. The participants in the studies were from both genders and all ages. The type of the pathology which included in this research was chronic calcific rotator cuff tendinopathy. Regarding the intervention types both Radial, and Focused ESWT with low, medium, and high intensities and the arthroscopic interventions were the main types of...
