Intraorifice sealing ability of different materials in endodontically treated teeth.
2010
Objectives To evaluate Cavit TM G, ProRoot TM MTA and Tetric® EvoFlow as intraorifice barriers to prevent coronal microleakage in root canal treatment. Study design Forty-two human single rooted teeth were divided randomly in three experimental groups of 10 specimens each and two control groups. The experimental groups were prepared with hand instrumentation and cold lateral condensed technique of the gutta-percha. Four millimetres of coronal gutta-percha were removed and replaced by one of the following filling materials: Cavit TM G, Tetric® EvoFlow or ProRoot TM MTA. In the experimental groups, leakage was measured by the concentration of leaked glucose in the apical reservoir at 1, 7, 30…
Leakage in root canal system during and after treatment: A review
2017
During and after a canal treatment any ingress of germs in the pulp space should be avoid because they are responsible for pulpal and periradicular diseases. Often this treatment is performed in more than one visit and amongst those visits a temporary restoration should impede the re-infection. Initially a pre-treatment (build-up) is required in order to prevent fluid leakage and allow a better isolation by rubber dam and a stabilised clamp. Several restorative materials are on the market and a correct choice is crucial to avoid failure considering several factors such as canal dressing medication, number of day between visits, extension of restoration, occlusal load, presence of parafuncti…
Quantitative thermoelastic stress analysis by means of low-cost setups
2020
Abstract A low-cost Thermoelastic Stress Analysis (TSA) experimental setup is proposed which uses an ordinary micro-bolometer and in-house developed signal processing scripts. The setup is evaluated by analysing the thermoelastic signal from a tensile and a SENT specimen made of stainless steel AISI 304L, and the bolometer performances are compared with those of a state of the art photon detector. Signal processing is based on off-line cross-correlation, using a self-reference signal which is retrieved from the acquired thermal data. Procedures are in particular developed to recognise, quantify and correct errors due to spectral leakage and loss of streamed frames. The thermoelastic signal …
Technical details of the hand-sewn and circular-stapled anastomosis in robot-assisted minimally invasive esophagectomy.
2020
SUMMARY The circular mechanical and hand-sewn intrathoracic anastomosis are most often used in robot-assisted minimally invasive esophagectomy (RAMIE). The aim of this study was to describe the technical details of both techniques that were pioneered in two high volume centers for RAMIE. A prospectively maintained database was used to identify patients with esophageal cancer who underwent RAMIE with intrathoracic anastomosis. The primary outcome was anastomotic leakage, which was analyzed using a moving average curve. For the hand-sewn anastomosis, video recordings were reviewed to evaluate number of sutures and distances between the anastomosis and the longitudinal staple line or gastric c…
Ex vivo study of bacterial coronal leakage in indirect pulp treatment
2012
Objective: The aim of this study was to evaluate, ex vivo, bacterial coronal leakage with different antimicrobial agents applied to the dentine for indirect pulp treatment (IPT). Study Design: Sixty extracted teeth were prepared and randomly distributed into 5 groups (n=10): Group 1: no antimicrobial dentine treatment; group 2: 1% chlorhexidine (CHX)+1% thymol varnish (Cervitec®); group 3: 2 % CHX solution; group 4: 40% CHX varnish (EC40™) and group 5: Clearfil™ Protect Bond (CPB). Ten teeth served as controls. The teeth were restored using a resin-modified glass ionomer cement (GIC) and then mounted in a two-chamber device. The coronal access was exposed to Streptococcus mutans for 45 days…
Effect of post space preparation on apical seal : influence of time interval and sealer
2007
Objective: To assess the efficacy of two sealants to preserve the apical seal after root canal preparation and cementation of posts at 24 h or 72 h after endodontic treatment. Study design: Sixty human single-root teeth were instrumented and obturated using lateral compaction technique with EndoFill® [30] or AH-Plus® [30] and were prepared in one of three ways, leaving a 3 mm gutta percha remnant in all cases: without cast post preparation, with preparation after 24 h or after 72 h. After cementing the posts, the specimens were thermal cycled at 5 and 55?C in water baths, submerged in 2% methylene blue dye for 72 h, embedded in acrylic resin and cut transversally into three 1-mm apical sect…

2009
Methods The study group is yet represented by 33 patients: 17 males and 16 females (median age 76, range 70–89). The location of cancer was respectively: 5 (15, 15%) in the rectum, 15 (45, 45%) in the left colon, 11 (33, 33%) in the right colon, 1 (3, 3%) in the transverse colon, 1 (3, 3%) synchronous in the caecum and the sigmoid colon. The associated diseases observed were: chronic obstructive pulmonary disease, hypertension, diabetes mellitus, ischemic heart disease arterial vasculopathy.
Worldwide Techniques and Outcomes in Robot-assisted Minimally Invasive Esophagectomy (RAMIE): Results From the Multicenter International Registry
2022
OBJECTIVE: This international multicenter study by the Upper GI International Robotic Association aimed to gain insight in current techniques and outcomes of RAMIE worldwide.BACKGROUND: Current evidence for RAMIE originates from single-center studies, which may not be generalizable to the international multicenter experience.METHODS: Twenty centers from Europe, Asia, North-America, and South-America participated from 2016 to 2019. Main endpoints included the surgical techniques, clinical outcomes, and early oncological results of ramie.RESULTS: A total of 856 patients undergoing transthoracic RAMIE were included. Robotic surgery was applied for both the thoracic and abdominal phase (45%), o…
PS02.147: MANAGEMENT OF A SIMULTANEOUS HIGH ESOPHAGO-TRACHEAL FISTULA CAUSED BY ESOPHAGEAL STENT DUE TO ANASTOMOTIC LEAKAGE AFTER IVOR-LEWIS ESOPHAGE…
2018
Abstract Background Esophagotracheal perforation is a very severe complication. However, an esophagotracheal perforation caused due to an esophageal stent after anastomotic leakage after ivor-lewis resection, is even more complex and associated with high mortality. Therefore we present a case how we managed a high esophagotracheal perforation and anastomotic leakage after ivor-lewis resection of esophageal cancer, prior treated with neoadjuvant radiochemotherapy. Methods Case report A 71-year old patient was transferred to our center due to an esophagotracheal perforation at the proximal stent—and at 18–20 cm from the front teeth row. The stent had been placed due to anastomotic leakage aft…
P126 HIGH ESOPHAGOTRACHEAL FISTULA DURING STENT TREATMENT OF AN ANASTOMOTIC LEAKAGE AFTER ESOPHAGECTOMY
2019
Abstract Aim We present a case of a 71 year old female with a combined anastomotic leakage after ivor-lewis resection and esophagotracheal perforation. Background & Methods Anastomotic leakage after esophageal resection is still associated with high morbidity and mortality throughout hospitalization. Nowadays there are several methods to accomplish sufficient closure of the anastomotic leakage such as clipping and using fibrin sealant in smaller leakages. Severe insufficiencies are commonly treated using esophageal stents. In our case the use of such a stent (10cm covered) placed to an anastomotic leak following esophagectomy with high intrathoracic anastomosis lead to an esophagotrache…
