    We sought to evaluate the capability of high field strength MRI in depicting clinically important tendons and ligaments of the ankle joint using slice orientations parallel to the standard space directions without angulation. Patients (65) whose ankle joint complaints were not sufficiently clarified by conventional radiology sphere underwent MRI using plain T{sub 1}-weighted spin echo sequences. Tendons and ligaments were classified by three independent radiologists with regard to their perceptibility on images of the different slice orientations. Good perceptibility of at least two-thirds of each structure was observed with the possibility for a decision regarding continuity or rupture of the remaining part was given most frequently in the following slice orientations: Axially for the tendons of peroneus longus, peroneus brevis, tibialis posterior, flexor digitorum longus, flexor hallucis longus, tibialis anterior, extensor digitorum longus, and extensor hallucis longus muscles, and for the calcanear tendor (each over 94% of cases), anterior (68%) talofibular ligament, deltoid (77%), anterior (63%), and posterior (72%) tibiofibular ligaments and coronally for the calcaneofibular (39%) and posterior talofibular ligaments (70%). The sagittal orientation was never the favored one. Thus in most cases tendons and ligaments of the ankle joint can be sufficiently visualized by non-angulated spin echo sequences in standard slice orientations if the examination is performed in at least two slice directions.

    Full Text Available Die Magnet-Resonanz-Urographie (MRU ist ein relativ neues Verfahren in der Diagnostik des oberen Harntraktes. Das Ziel dieser Studie war der Vergleich der Aussagefähigkeit der MRU unter Gabe von Gadolinium und Furosemid und dem konventionellen Urogramm (IVU in der Diagnostik der Ursache von Obstruktionen im Bereich des Harnleiters. 82 Patienten mit im IVU nachgewiesener Obstruktion des oberen Harntraktes oder urographisch stummer Niere bei sonographisch nachgewiesener Dilatation wurden der MRU zugeführt. Die Bilder beider Untersuchungsmethoden wurden von voneinander unabhängigen Untersuchern befundet. Zwei Urologen befundeten die IVU-Bilder, zwei Radiologen die MRU-Bilder, die Radiologen kannten die IVU-Diagnose nicht. Bei unklarer Diagnose wurden weitere Untersuchungen wie Computertomographie, retrograde Pyelographie oder Ureteroskopie durchgeführt. Die Diagnosen waren: Harnleitersteine bei 72 Patienten, Harnleitertumore bei 8 Patienten und extraureterale Tumore bei 2 Patienten. Eine richtige Diagnose bei den Steinpatienten wurde durch IVU bei 49 von 72 Patienten und durch MRU bei 64 von 72 Patienten gestellt. In dieser Patientengruppe wurden durch die MRU zwei falsche Diagnosen gestellt. Fehlende Kontrastmittelausscheidung war der Hauptgrund für Versagen der IVU. 3 der 8 Patienten mit Harnleitertumoren wurden durch die IVU richtig dignostiziert, bei dreien wurde eine falsche Diagnose gestellt. Durch die MRU konnten in dieser Gruppe 7 von 8 Patienten korrekt diagnostiziert werden, es wurde keine falsche Diagnose erhoben. IVU wird zunächst die Standarduntersuchungstechnik zur Darstellung des oberen Harntraktes bleiben, aber durch diese Studie konnte die Möglichkeit gezeigt werden, die in der MRU in Kombination mit Gadolinium und Furosemid liegt. Die größte Bedeutung dieser Untersuchung liegt in der urographisch stummen Niere, bei Untersuchungen in der Schwangerschaft, bei Kindern und bei Patienten mit Kontrastmittelunverträglichkeit.

    Full Text Available Urotheliale Tumoren des oberen Harntraktes sind selten. Sie repräsentieren nur etwa 5 % aller Urothelkarzinome. In der vorliegenden Studie wurden Tumorparameter, demographische Faktoren, diagnostische und therapeutische Maßnahmen sowie die Follow-up-Daten von 28 Patienen mit Urothelkarzinomen des oberen Harntraktes analysiert und retrospektiv bezüglich der Effektivität diagnostischer Methoden (Urinzytologie, Ausscheidungsurogramm, retrogrades Ureteropyelogramm, CT, Endoskopie sowie hinsichtlich des therapeutischen Vorgehens ausgewertet. Zusätzlich fanden das histopathologische Tumorstaging, das Grading der Tumoren sowie die Rezidivhäufigkeit und das Patientenüberleben Berücksichtigung. Die Hauptsymptome waren eine Hämaturie in 60,0 % und Flankenschmerzen in 39,0 %. Eine Urinzytologie wurde bei 17 Patienten (60,7 % durchgeführt, mit richtig-positivem Ergebnis in 8 Fällen (47,0 %.

    Purpose: To compare digital X-ray, CT, and MRI in the evaluation of ligamentous and osseous lesions in upper cervical spine specimens after artificial craniocervical injury with the findings of macroscopic preparation. Materials and Methods: A rotation trauma of defined severity was applied to 19 human corpses. After dissection of the neck specimens, digital X-ray (DIMA Soft P41, Feinfocus), conventional and helical CT (CTi, High Speed, GE, collimation 1 mm; pitch 1.0), and MRI were performed from the skull base to C3. The findings were correlated with the macroscopic results of preparation. MR (Magnetom Vision, Siemens) imaging was obtained with a 1.5 T system using 2D- and 3D-sequences. Results: Preparation revealed 6 fractures of the vertebral bodies, 5 fractures of the dens axis, 1 fracture of the arcus anterior of the atlas, 4 osseous flakes at the occipital condylus, and 6 lesions of the alar ligaments. Digital radiography showed all fractures and 4 osseous flakes at the occipital condylus. With conventional and helical CT, all fractures and all ruptured alar ligaments could be detected. 2D MRI depicted 9 of the fractures and 3D MRI showed fractures. With 2D MRI, 2 of the 4 osseous flakes at the condylus could be detected and with 3D MRI one occipital condylus fracture could be depicted. Ligamentous injuries were visualized by 2D MRI in 2 of 6 cases and by 3 D MRI inone case. Conclusions: In post-mortem studies, CT was superior to MRI in the visualization of osseous and ligamentous injuries after trauma of the upper cervical spine. However, these results are not transferable to patients with rotation injury in general. (orig.)

    Conventional radiography plays an essential role in the primary evaluation of acute ankle and foot trauma. In the case of complex injuries, however, subsequent computed tomography (CT) is nowadays recommended. In this connection, multidetector computed tomography (MDCT) allows better temporal, spatial, and contrast resolution compared with the conventional single-slice spiral CT. Multiplanar reformation and three-dimensional reconstruction of the acquired data sets are also helpful tools for critical assessment of therapeutic intervention. This report reviews the potential of the MDCT technique for accurate fracture classification, precise illustration of displaced components, and postoperative control of arrangement of typical lesions. (orig.) [German] Die konventionelle Radiographie spielt bei der initialen Diagnostik akuter Verletzungen des oberen Sprunggelenks und des Fusses eine essenzielle Rolle. Im Falle komplexer Frakturen ist jedoch eine weiterfuehrende computertomographische Diagnostik empfehlenswert. Dabei ist die Multidetektorcomputertomographie (MDCT) der konventionellen Einzeilencomputertomographie hinsichtlich Zeit-, Orts- und Kontrastaufloesung deutlich ueberlegen. Die multiplanare Reformation und dreidimensionale Rekonstruktion des akquirierten Datensatzes sind zudem bei der Beurteilung therapeutischer Interventionen aussagekraeftige Werkzeuge. Der vorliegende Beitrag gibt einen Ueberblick ueber die exakte Frakturklassifikation, die praezise Abbildung dislozierter Komponenten und die postoperative Stellungskontrolle typischer Verletzungen mit dieser Technik.

    Purpose: To evaluate technique and practicability of MR-guided percutaneous nephrostomy (MRPCN) in an animal model. Methods: In three domestic pigs, a unilateral percutaneous nephrostomy tube was placed into the nondilated collecting system using exclusively MR-guidance with a standard 1.5 T scanner. The urinary tract was visualized by intravenous injection of Gd-DTPA and low-dose furosemide. The entire interventional procedure was controlled using a T{sub 1}-weighted `dual stack` 2D TFE sequence in two orthogonal planes. Results: In all three animals, the puncture needle was safely directed into the nondilated target calyx. Even slight deviations of the needle from the optimal path were readily detected on both MR image planes which enabled immediate correction. This technique successfully achieved a `first attempt` puncture of the targeted calyx in each animal. Over a nitinol guidewire a 5 F catheter was placed into the renal pelvis. Its dysprosium labelled tip was acurately delineated on contrast-enhanced MR images. Conclusions: Percutaneous nephrostomy under MR guidance is a very feasible technique for puncturing the nondilated pelvicalyceal system. This procedure offers some advantages over the current standard modalities. (orig.)

    2009-01-01

    Full Text Available In den letzen 10 Jahren sind sowohl in der Diagnostik als auch in der Therapie des Blasenkarzinoms Fortschritte erzielt worden. In der Diagnostik sind mit den Tumormarkern, beispielsweise NMP22 und UroVysion Instrumente implementiert worden, die sensitiver sind als die Urinzytologie und somit als Alternative und ergänzende Untersuchungen zur Zystoskopie betrachtet werden können. Die Fluoreszenzzystoskopie kann rund 20 % mehr Tumoren entdecken als die Weisslichtzystoskopie, es kommt nach TUR-B zu rund 20 % weniger Resttumoren und auch ca. 20 % weniger Rezidiven im Langzeitverlauf. Als Rezidivprophylaxe kann bei Low-grade-Tumoren eine einmalige Instillation eines Chemotherapeutikums unmittelbar nach TUR-B empfohlen werden und bei High-risk-Tumoren ein BCG-Instillationszyklus. Bei Versagen der BCG-Therapie muss die Zystektomie erwogen werden. Im Rahmen der Zystektomie soll die ausgedehnte pelvine Lymphadenektomie durchgeführt werden; der therapeutische Nutzen ist suggestiv, aber nicht bewiesen. Mittels Nerve-sparing-Technik kann, sofern durchführbar, die Kontinenz nach orthotopem Blasenersatz schneller und in einem leicht höheren Prozentsatz erreicht werden und der Erhalt der erektilen Potenz ist möglich. Die kontinenten Harnableitungen mittels orthotopem Blasenersatz oder katheterisierbarem Pouch haben sich etabliert. Dabei ist der Reflux in den oberen Harntrakt beim orthotopen Blasenersatz unerheblich; die Langzeitresultate in Bezug auf Erhaltung der Nierenfunktion sind bei offener Anastomose exzellent. Deshalb kann auf eine antirefluxive Implantation der Harnleiter wegen höherer Strikturierungsrate zugunsten einer offenen Anastomose verzichtet werden. Laparoskopische und roboterassistierte Zystektomien sind machbar, aber im Moment spezialisierten Zentren vorbehalten. Die Chemotherapie, aktuell meist mit Gemcitabin und Cisplatin durchgeführt, hat ihren Platz beim fortgeschrittenen Blasenkarzinom. Im Rahmen einer neoadjuvanten Indikation

Det står altså skidt til med et begreb om festivalen, og dette endog...... til trods for, at der er forsket i festivalen som fænomen siden det 19. århundrede – tilmed inden for en række forskellige faglige discipliner såsom religionsvidenskab, sociologi, antropologi, folklore m.fl. Endnu mere sparsomt må det vel så også stå til med bud på, hvad fødens festival er for en...

    Norma Belfiore

    2012-10-01

    Full Text Available Introduction Microcrystalline deposition in peri-odontoid articular structures is mainly responsible for acute or chronic cervical pain and is known as “crowned dens syndrome”.Materials and methods We described two cases of acute cervical pain associated with onset of fever and peripheral acute monoarthritis. Cervical computed tomography (CT scan showed linear calcification of the retrodens ligament and calcium pyrophosphate dehydrate (CPPD crystals were found in synovial fluid of inflamed joints. Both patients were treated with anti-inflammatory drugs and colchicine.Discussion Calcium depositions around the odontoid process of the axis can be occasionally detected by radiological studies. They are frequently asymptomatic but sometimes can be associated with severe neurological abnormalities, fever and acute neck pain. CPPD crystals are usually deposited in joints and bursae but occasionally can disrupt these anatomical confines and deposit in periarticular tissues, sometimes forming large masses confused with tumours.Conclusions Acute onset of cervical neck pain associated with elevation of inflammatory indicators and/or signs of cervical myelopathy should suggest CT scans searching for microcrystal depositions in the peryodonthoid tissue. Differential diagnosis of fever of unknown origin (FUO should include crowned dens syndrome specially in the elderly after exclusion of several endocrine or metabolic disorders, infection diseases (meningitis, arthritis (psoriatic arthritis and ankylosing spondylitis and tumours (chordoma, meningioma, osteoblastoma.

    2012-05-01

    Dens invaginatus or 'dens in dente' is a developmental malformation of the tooth resulting from infolding of the dental papilla before calcification. This article presents a case of dens invaginatus occurring in maxillary right lateral incisor of a 45-year-old male patient. The patient presented with pain and clinically missing maxillary right canine. The tooth was found to be non-vital. Radiographic examination revealed the tooth-in-tooth appearance of lateral incisor with a dilated pulp chamber. The crown of impacted canine was found within the pulp chamber of lateral incisor. Owing to this unique clinical presentation, both the lateral incisor and the impacted canine were extracted. Histopathologic examination confirmed the diagnosis of Dens invaginatus Type III B. A brief review on etiopathogenesis, radiographic features and treatment of dens invaginatus has also been included.

  5. Den iscenesatte folkelighed

    Néstor Garcia Canclini

    1994-09-01

    Full Text Available Hvad er "det folkelige" og hvad er "folkekultur"? Néstor Garcia Canclini har i denne artikel sat sig for at dekonstruere begrebet "det folkelige" og beskrive den måde, forskellige grupper bruger og misbruger begrebet på. Han analyserer tre fremherskende idéer om folkelighed: folkloristernes romantiske idé om det oprindelige, der blev ødelagt af massekulturen, massemediernes popularitetsbegreb og endelig populisternes - både de højre- og venstreorienteredes - iscenesættelse af folkeligheden. Desuden ser han på to marxistiske skolers opfattelse af forholdet mellem de dominerende og undertrykte klasser og forskellige definitioner af folkelig- hed. Ligesom Anamaria Fadul argumenterer Canclini for nødvendigheden af en ny, tværdiciplinær forskning, som opfanger kompleksitet og flerty- digheder i forholdet mellem de undertrykte og dominerende og ser "det folkelige" som en tragisk komedie med modsætninger og flertydighed snarere end en evigt fremadskrivende episk fortælling.

    Directory of Open Access Journals (Sweden)

    2004-12-01

    Full Text Available In der gegenwärtigen Verkündigung des Wortes Gottes spielt die Veranschaulichung der Überlieferung eine nicht zu überschätzende Rolle. Vor diesem Hintergrund wird es sehr wichtig, dass man den Predigern nicht nur auf die Funktion des Bildes in der Verkündigung, sondern auch auf die Art und Weise seines Entstehens auf der narrativen Ebene aufmerksam macht. Während die Kenner der Homiletik die Notwendigkeit des Auftretens der Bildeigenschaften in den Predigten betonen, erinnern sie gleichzeitig daran, dass der moderne, von der „Bild-Zivilisation“ gestaltete Mensch, „immer mehr sehen als hören“ möchte. Der vorliegende, die Rundfunkpredigten von der Heiligkreuz-Kirche analysierende Aufsatz, nimmt auf und bringt zugleich nahe die Problematik der Notwendigkeit des Bildes in der Wort-Gottes-Verkündigung. Der Artikel stellt die Erzählungsform als eine wichtige Möglichkeit der Glaubensüberlieferung dar, behandelt das Problem der Aktualisierung evangelischen Werte, bringt das von den Predigten gestaltete synästhetische Weltbild nahe und analysiert die Rolle des Zitats und Beispiels (exemplum bei der Gestaltung der Bildhaftigkeit einer Predigt.

Denne forståelse er kraftigt inspireret af Emmanuel Lévinas’fænomenologiske nærhedsetik, der forstår æstetik og etik som...... antagonistiskefænomener. Med afsæt i denne forståelse anser Bauman æstetiseringen af denAnden, som en maskering af det nøgne ansigt, der ifølge Lévinas er den etiskefordrings kilde. Hermed mødes den Anden ikke som et unikt menneske, mensnarere som et overfladisk objekt, der nydes uden etisk ansvar. Artiklen pegerpå......, at Knud E.

  5. Dens evaginatus and dens invaginatus in all maxillary incisors: report of a case.

    Science.gov (United States)

    Vardhan, Talla Harsha; Shanmugam, Subramanyam

    2010-02-01

    Dens evaginatus is a developmental malformation characterized by the presence of an extra cusp that takes the form of a tubercle arising from the occlusal or the lingual surface of the tooth. It is also referred to as talon cusp in the anterior teeth and Leong premolar in the premolars. Dens invaginatus is a deep surface invagination of the crown or the root lined by enamel, dentin, and pulp. Though many case reports of dens evaginatus and dens invaginatus have been found in the literature, an association of both is a rare anomaly. Only two cases of concomitance of dens invaginatus and dens evaginatus have been reported. This article is a case report of dens evaginatus and dens invaginatus involving all four maxillary incisors in a 25-year-old patient.

    2014-09-01

    Dens invaginatus is a developmental malformation of teeth related to shape of the teeth. Affected teeth show a deep infolding of enamel and dentin starting from the tip of the cusps and may extend deep into the root. It results from the invagination of the enamel organ into the dental papilla before calcification has occurred. Teeth most affected are maxillary lateral incisors. The presence of dens invaginatus in mandibular canine is extremely rare. The tooth was symptomatic in that it was mobile and was oriented horizontally. This article presents a case of symptomatic dens invaginatus in mandibular canine.

  17. Rare associations of dens invaginatus and mesiodens.

    Science.gov (United States)

    Sannomiya, Eduardo Kazuo; Asaumi, Jun-ichi; Kishi, Kanji; Dalben, Gisele da Silva

    2007-08-01

    Dens invaginatus is a developmental variation resulting from an alteration in the normal growth pattern of the dental papilla. Synonyms of this disturbance include dens in dente, invaginated odontome, tooth inclusion, and dentoid in dente. Radiographically, it is observed as infolding of a radiopaque ribbon-like structure, with equal density as enamel, extending from the cingulum into the root canal and sometimes reaching the root apex, assigning the appearance of a small tooth within the coronal pulp cavity. This article presents 2 case reports. The first describes an 8-year-old girl with dens invaginatus in a mesiodens; the second report describes a 16-year-old boy presenting with 2 mesiodens, both associated with dens invaginatus.

  3. Polar bear maternity denning in the Beaufort Sea

    Science.gov (United States)

    Amstrup, Steven C.; Gardner, Craig L.

    1994-01-01

    The distribution of polar bears (Ursus maritimus) is circumpolar in the NOrthern Hemisphere, but known locations of maternal dens are concentrated in relatively few, widely scattered locations. Denning is either uncommon or unknown within gaps. To understand effects of industrial development and propose increases in hunting, the temporal and spatial distribution of denning in the Beaufort Sea must be known. We caputred and radiocollared polar bears between 1981 and 1991 and determined tht denning in the Beaufort Sea region was sufficient to account for the estimated population there. Of 90 dend, 48 were on drifting pack ice, 38 on land, and 4 on land-fast ice. The portions of dens on land was higher (P= 0.029) in later compared with earlier years of the study. Bears denning on pack ice drifting as far as 997 km (x=385km) while in dens. there was no difference in cun production by bears denning on land and pack ice (P =0.66). Mean entry and exit dates were 11 November and 5 April for land dens and 22 November and 26 March for pack-ice dens. Female polar bears captured in the Beaufort Sea appeared to be isolated from those caught eat of Cape Bathurst in Canada. Of 35 polar bears that denned along the mainland coast of Alaska and Canada 80% denned between 137 00'W snf 146 59'W. Bears followed to >1 den did not reuse sites and consecutive dens were 20-1,304 km apart. However radio-collared bears are largely faithful to substrate (pack-ice, land, and land-fast ice) and the general geographic area of previous dens. Bears denning on land may be vunerable to human activities such as hunting and industrial development. However, predictable denning chronology and alck of site fidelity indicate that many potential impacts on denning polar bears could be mitigated.

  4. Virtual endoscopy of the upper urinary tract based on contrast material-enhanced MR urography data sets; Virtuelle Endoskopie des oberen Harntraktes auf der Basis kontrastangehobener MR-Urographie Datensaetze

    1999-06-01

    Purpose: To investigate the feasibility of reconstructing a virtual endoscopy from MR imaging data sets of the upper urinary tract. Method: The data obtained from 28 contrast-enhanced MR urographic examinations (5 normal; 23 pathologic) were post-processed to reconstruct a virtual ureterorenoscopy (VURS) using a threshold image segmentation. The visualization of the upper urinary tract was based on the acquisition of T{sub 1}-weighted 3D gradient-echo sequences after intravenous administration of gadolinium-DTPA and a prior injection of low-dose furosemide. Results: The employed MR urography technique created in all 28 cases a complete and strong contrast enhancement of the urinary tract. These 3D sequence data allowed the reconstruction of a VURS, even when the collecting system was not dilated. The best accuracy was provided by the MR urography sequences with the smallest voxel size. Moreover, the data acquisition based on a breath-hold technique has proved superior to that using a respiratory gating. Inside the renal pelvis, all calices could be assessed by turning the virtual endoscope in the appropriate direction. The visualization of the ureteral orifices in the bladder was also possible. All filling defects that were diagnosed by MR urography could be evaluated from the endoluminal view using the VURS. The exact characterization of the lesions based only on the assessment of the surface structure was difficult. Conclusion: A virtual endoscopy of the upper urinary tract can be successfully reconstructed using the data sets of high-resolution 3D MR urography sequences. (orig.)

  6. Dens invaginatus: diagnosis and management strategies.

    Science.gov (United States)

    Gallacher, A; Ali, R; Bhakta, S

    2016-10-07

    Dens invaginatus is a developmental malformation, in which there is an infolding of enamel into dentine. These infolds represent stagnation sites for bacteria and can predispose to dental caries. The carious infection can spread via enamel and dentine to contaminate the pulp and cause soft tissue necrosis. The altered and sometimes complex anatomy of affected teeth can make endodontic management challenging. Early diagnosis is therefore essential as prophylactic treatment of the dens can prevent degeneration and pulpal necrosis. The aim of this article is to review the aetiology, classification, diagnosis and management of teeth affected with dens invaginatus. Emphasis will be placed on describing the clinical features of this anomaly. Treatment options, management strategies and the challenges faced in managing this condition will be discussed.

    Full Text Available Dens invaginatus is a developmental anomaly resulting from an invagination in the surface of a tooth crown before its calcification. It involves more commonly maxillary anterior teeth. Dens invaginatus with supernumerary teeth and double dens invagintus were also reported. The management of dens invaginatus includes simple prophylactic restoration to conventional endodontic treatment or extraction, depending on the type of invagination, function, esthetics, and morphology of the root canal. Extraction is indicated as a last choice of treatment in cases of failure of root canal treatment and in supernumerary teeth associated with dens invaginatus. In this paper, we have reported a series of cases of dens invagintus.

    MR imaging is being increasingly used for the diagnosis of congenital urinary tract obstruction. The following conditions have to be fulfilled to provide an MR urography technique which is useful for the pediatric age group: (1) the combination of morphology and function, (2) a high-resolution morphological image, (3) a morphological image independent of kidney function, (4) reliable determination of split renal function and (5) of urinary excretion. This is best accomplished with a combination of a T1-weighted fast GE sequence post-contrast and a heavily T2-weighted 3D IR-TSE sequence. Selected sequence parameters are important for optimization as well as for a correct functional assessment. Then MR urography is superior to the conventional methods of excretory urography, ultrasound, and scintigraphy in the morphological depiction of the urinary tract even of complex malformations as well as in a detailed functional assessment. In particular, this method is useful in the situation of complicated duplex kidneys, dystopic kidneys, unclear morphology, or discrepant former results and perioperative assessment. The main advantages are avoiding radiation and obtaining a simultaneous functional-morphological diagnosis. (orig.) [German] Zur Diagnostik angeborener Harnwegfehlbildungen und Harntransportstoerungen wird zunehmend die MRT eingesetzt. Voraussetzungen fuer eine sinnvolle MR-Urographie-Technik im Kindesalter sind 1. die Kombination von Morphologie und Funktion, 2. eine hochaufloesende morphologische Abbildung, 3. ein funktionsunabhaengiges morphologisches Bild, 4. die zuverlaessige Bestimmung der seitengetrennten Nierenfunktion und 5. des Harnabflusses. Dies wird am besten mit einer Kombination aus T1-gewichteter schneller GE-Sequenz nach KM und stark T2-gewichteter 3D-IR-TSE-Sequenz erreicht. Wichtig zur Optimierung sowie zur korrekten Funktionsbestimmung ist die gezielte Wahl der Sequenzparameter. Dann ist die MR-Urographie den konventionellen Methoden AUG

    2015-01-01

    The presence of dens invaginatus (DI) and dens evaginatus (DE) on same tooth is a rare phenomenon. However, when these dental anomalies occur on a double tooth, it becomes an extremely rare phenomenon. The authors report a rare case of DI and DE on fused permanent maxillary central incisor with supernumerary tooth in a 40-year-old male. The present article also focuses on the differentiating fusion from gemination and also reviews preventive and management strategies for tooth with complex dental anatomy.

    Polar bears (Ursus maritimus) give birth in dens of snow and ice. The altricial neonates cannot leave the den for >2 months post-partum and are potentially vulnerable to disturbances near dens. The coastal plain (1002) area of Alaska's Arctic National Wildlife Refuge (ANWR) lies in a region of known polar bear denning and also may contain >9 billion barrels of recoverable oil. Polar bears in dens could be affected in many ways by hydrocarbon development. The distribution of dens on ANWR was documented between 1981 and 1992 and responses of bears in dens to various anthropogenic disturbances were observed. Of 44 dens located by radiotelemetry on the mainland coast of Alaska and Canada, 20 (45%) were on ANWR and 15 (34%) were within the 1002 area. Thus, development of ANWR will increase the potential that denning polar bears are disturbed by human activities. However, perturbations resulting from capture, marking, and radiotracking maternal bears did not affect litter sizes or stature of cubs produced. Likewise, 10 of 12 denned polar bears tolerated exposure to exceptional levels of activity. This tolerance and the fact that investment in the denning effort increases through the winter indicated that spatial and temporal restrictions on developments could prevent the potential for many disruptions of denned bears from being realized. 16 refs., 1 fig., 2 tabs.

    2015-01-01

    Full Text Available Dens evaginatus is an uncommon developmental anomaly of human dentition characterized by the presence of tubercle on the occlusal surface of mandibular premolars and lingual surface of anterior teeth. Due to occlusal trauma this tubercle tends to fracture thus exposing the pathway to the pulp chamber of teeth. This case report is about the presentation of dens evaginatus in mandibular premolars bilaterally; among them tooth 44 was associated with chronic apical periodontitis. Fractured tubercle of three premolars was sealed with composite resin. Root canal treatment was performed with tooth 44. Routine endodontic treatment did not result in remission of infection. Therefore, culture and sensitivity tests were performed to identify the cause and modify treatment plan accordingly. Triple antibiotic paste was used as an intracanal medicament to disinfect the root canal that resulted in remission of infection.

    Full Text Available Dens invaginatus (DI (dens in dente is a developmental anomaly resulting from an invagination in part of variable depth of the enamel organ into the dental papilla in the surface of the crown before calcification of the dental tissues. This anomaly usually involves the upper lateral incisors. These teeth are frequently expressed by an unusual form of crown and accentuation in the cingulum or a cusp. They are a target for caries leading to pulp necrosis and apical pathosis, so the diagnosis and early prevention measures are important. When treatment is necessary, conservative, endodontic, and periodontal possibilities are very effective. Surgical interventions are only rarely indicated. The present paper deals with the treatment of series cases with DI.

  1. Simultaneous Occurrence of Dens Invaginatus and Fusion

    Directory of Open Access Journals (Sweden)

    Amit Mhapuskar

    2013-01-01

    Full Text Available Although Dens invaginatus and fusion are well-known and well established dental anomalies, they are rarely seen in supernumerary teeth. In this article, simultaneous occurrence of Dens invaginatus and fusion between maxillary lateral incisor and a supernumerary tooth is described. Dens invaginatus is clinically significant due to the possibility of the pulpal involvement; pulpitis, necrotic pulps and chronic periapical lesions are often associated with this anomaly without clinical symptoms. Fusion has a negative impact on the aesthetics, especially when it occurs in maxillary anterior teeth. It is difficult to clinically make differential diagnosis between fused teeth and geminated teeth, especially when these anomalies take place together with hypodontia or supernumerary tooth. It has been found that sequel of such teeth may result in delayed eruption, ectopic eruption or even impaction of permanent teeth; hence proper diagnosis by clinical and radiographic methods and intervention at appropriate time is of paramount importance. The accurate knowledge of variations in morphology of tooth and pulp cavity greatly assists the dentist in planning successful treatment options.

    2006-01-01

    Dens invaginatus, commonly known as dens in dente, is a developmental malformation of teeth that most commonly affects permanent maxillary lateral incisors. Deciduous teeth are infrequently affected. Presence of dens invaginatus in mandibular permanent teeth is extremely uncommon. A rare presentation of coronal double dens invaginatus incidentally detected in a mandibular canine tooth on radiographic examination is being reported, along with a discussion of this anomaly. The patient had presented for routine dental treatment unrelated to this finding. In addition, the various radiographic appearances of dens invaginatus, as they present within the maxillary and mandibular teeth, are described. Essential clinical considerations and treatment options are presented. A review of the pertinent literature is undertaken, and tables summarizing previously published reports of mandibular dens invaginatus and double dens invaginatus are presented. A review of the literature indicates that dens invaginatus in mandibular teeth is extremely rare, with only 11 other cases, involving 14 teeth, reported previously. Cases of double dens invaginatus are even more atypical, with only eight previously reported cases. Dens invaginatus is an anomaly that should be familiar to all practicing dentists because of the clinical implications and potential sequelae.

    Dens invaginatus is a malformation with varying anatomical features, posing challenges to treatment. Early and accurate diagnosis plays a significant role in selecting the appropriate treatment. The diagnosis of teeth with a complex root canal system including dens invaginatus has made progress with the application of three-dimensional imaging techniques in endodontics. Advanced treatment options provide hope for teeth that could not be saved before. This review discusses diagnostic methods and treatment options for teeth with dens invaginatus, and provides guidelines for the management of dens invaginatus cases in clinic. Current as well as traditional diagnostic techniques are summarized. Treatment options including state-of-the-art alternatives are presented for coronal dens invaginatus and radicular dens invaginatus. © 2017 Australian Dental Association.

Die Zeit der Romantik in Europa ermöglichte die Schaffung von Nationalstaaten und ihr Hauptmerkmal war die Nationalsprache. Diese Art der sozialen Differenzierung hatte das Ziel, die Illusion einer vollständig homogenisierten Gesellschaft zu schaffen und damit den Prozess der Zerstörung der „kleinen“ Sprachen zu beginnen.

    Castellarin, M; Demitri, V; Politi, M

    2001-01-01

    The aim of this paper is to propose a single stage global treatment of endodontic, periapical and periodontal lesions in a lateral maxillary incisor with dens invaginatus. A 24 year-old woman presenting a lateral maxillary incisor with dens invaginatus in association with periapica1 and periodontal lesions underwent simultaneous surgical, endodontic and periodontal regenerative procedures. At 2, 6, 12, 18 months follow-up the radiographic healing appeared to be improved and the periapical lesion healed completely 1 year after surgical intervention. Surgery in association with endodontic and periodontal procedures represents the treatment of choice to maximize long term prognosis in cases of dens invaginatus with chronic periapical and periodontal lesions.

    2006-01-01

    Dies ist die Geschichte von Einsteins unvollendeter Revolution, einer tiefgreifenden Veränderung unserer Begriffe von Raum, Zeit, Materie und Strahlung. Diese Revolution begann in Einsteins Wunderjahr 1905, wurde durch seine allgemeine Relativitätstheorie aus dem Jahre 1915 fortgesetzt und wirkt in den heutigen Versuchen der Wissenschaft, die Entstehung und das Schicksal des Universums zu verstehen, weiter. Vor dem Hintergrund einer historischen Theorie des wissenschaftlichen Fortschritts wird Einsteins bis heute nicht abgeschlossene Revolution als das Ergebnis einer langfristigen Entwicklung des Wissens verständlich. Anhand der spannenden Geschichte von Einsteins Entdeckungen wird nachvollziehbar, warum große Denker wie Einstein weiter gesehen haben als ihre Vorgänger. Sie standen nicht nur auf den Schultern von Riesen, also den wissenschaftlichen Leistungen einzelner großer Vorgänger wie Newton, sondern auch auf den Schultern von "Zwergen", dem wissenschaftlichen Wissen, dem technischen Wissen, und d...

    2012-01-01

    Dens invaginatus is a rare developmental morphoanatomical variation resulting from the infolding of the dental papilla before biological mineralization that allows the invagination of inner dental epithelium. Permanent maxillary lateral incisors are most commonly affected, and the condition is frequently bilateral, but it may also prevail in permanent maxillary central incisors. The purpose of this paper was to provide an overview of the etiopathogenesis, frequency of occurrence, and clinical and radiographic features and to discuss 3 dens invaginatus cases.

    Dens invaginatus is a rare malformation affecting the teeth. The teeth that are most commonly affected are the permanent maxillary lateral incisors. The mandibular posterior teeth are rarely affected by dens invaginatus. In most of the cases, a single dens invaginatus is seen affecting the tooth. Cases of double dens invaginatus affecting a single tooth are rare, and those of triple dens invaginatus in a single tooth are even rarer. Here, we present a case of a 14-year-old where three dens invaginatus were seen in the mandibular second premolar. This is the fourth case of three dens invaginatus in a single tooth as only three have been reported previously.

    This case report, involving an indigenous Australian, presents the diagnosis and non-surgical endodontic management of a 22 with developmental abnormalities. They include a dens evaginatus and a dens invaginatus that extends to an apical burst in a second truncated root. Cone-beam computed tomography and endodontic microscopy were not available to the clinician. This case report focuses on ambiguities appearing in the literature relating to classification and terminology associated with the abovementioned developmental anomalies. It also demonstrates the need to methodically collect and cautiously interpret available information before initiating endodontic intervention. Axial inclination, distance perception, internal demarcation and spatial awareness, together with an understanding of dental anatomy, embryology and histology and associated physiology and pathology, allowed the clinician to accurately predict the point, the angle and the depth of coronal access. Sensibility of the dentino-pulpal complex was maintained. Critical thinking, experience, innovation, problem-solving and established principles can compensate for inaccessible technologies. © 2014 Australian Society of Endodontology.

    2012-01-01

    This study describes a clinical case of type III dens invaginatus with an extensive periradicular lesion treated successfully. Dens invaginatus is a maldevelopment of the dental germ which occurs as a result of the invagination of the enamel organ. These cases may present difficulties with respect to its diagnosis and treatment because of canal morphology. The success of endodontic therapy requires a knowledge of dental anatomy and its anomalies. A 17-year-old female patient is reported presenting right maxillary lateral incisor (tooth no. 7) classified as type III dens invaginatus with necrotic pulp and presence of an extensive radiolucid lesion. Endodontic treatment was recommended for tooth. However, intracanal exudate was present, suggesting a resistant infection. Enucleation of the lesion was performed as a complementary approach. The root canal obturation was carried out by the gutta-percha thermoplastification technique with root canal sealer, followed by restoration of the tooth. Healing of the lesion with hard tissue formation was confirmed at follow-up. A combination of endodontic and surgical treatments were fundamental to the maintenance of the tooth. The treatment was considered successful. Root canal therapy of dens invaginatus should be based on a thorough clinical and radiographic evaluation. The knowledge of classification and anatomical variations of teeth with dens invaginatus are of great importance for correct treatment.

  6. American black bear denning behavior: Observations and applications using remote photography

    2004-01-01

    Researchers examining American black bear (Ursus americanus) denning behavior have relied primarily on den-site visitation and radiotelemetry to gather data. Repeated den-site visits are time-intensive and may disturb denning bears, possibly causing den abandonment, whereas radiotelemetry is sufficient only to provide gross data on den emergence. We used remote cameras to examine black bear denning behavior in the Allegheny Mountains of western Virginia during March-May 2003. We deployed cameras at 10 den sites and used 137 pictures of black bears. Adult female black bears exhibited greater extra-den activity than we expected prior to final den emergence, which occurred between April 12 and May 6, 2003. Our technique provided more accurate den-emergence estimation than previously published methodologies. Additionally, we observed seldom-documented behaviors associated with den exits and estimated cub age at den emergence. Remote cameras can provide unique insights into denning ecology, and we describe their potential application to reproductive, survival, and behavioral research.

    Das Gamma-Weltraumteleskop INTEGRAL der Europäischen Weltraumbehörde, ESA, hat in den ersten 15 Monaten seiner Mission eine Fülle interessanter, neuer Ergebnisse geliefert. Hauptinstrumente an Bord sind das hoch auflösende Spektrometer SPI und das Spektrometer IBIS. Hinzu kommt je ein Monitor für den Röntgen- und optischen Bereich. Die wichtigsten neuen Erkenntnisse stammen vor allem aus dem Bereich harter kompakter Röntgenquellen und aus dem Bereich der Gammalinien-Spektroskopie. Mit INTEGRAL wurde es erstmals möglich, den diffusen galaktischen Hintergrund zum Teil mit Einzelquellen identifizieren zu können. Ferner ließ sich in der Umgebung des galaktischen Zentrums die 511-keV-Linie von annihilierenden Positronen und Elektronen nachweisen. Schließlich trägt INTEGRAL auch entscheidend zum Studium der geheimnisvollen Gamma Ray Bursts bei.

    George, Roy; Moule, Alexander J; Walsh, Laurence J

    2010-08-01

    Dens invaginatus (dens in dente) is a common dental anomaly with a reported prevalence of between 0.04% and 10%. It typically affects permanent maxillary lateral incisors, central incisors and premolars. These developmental lesions are less common in mandibular teeth and are extremely rare in canines and molars. This report describes a rare case of dens invaginatus (Oehlers type II) in a permanent mandibular canine. The tooth was mature with a closed apex and showed apical pathosis. The tooth was treated endodontically using a non-surgical technique with hand endodontic files, and then followed up after a period of 8 months. A follow-up radiograph showed some healing of the lesion.

    Chun-Ming Chen

    2005-07-01

    Full Text Available Dens evaginatus is a developmental anomaly that produces a tubercle on the occlusal surface of a tooth. It is found most frequently in the mandibular premolars. The occlusal tubercle easily causes occlusal interferences. Attrition or fracture of the tubercle can lead to pulpitis, pulp necrosis, periapical pathosis, and periapical infection. This case report illustrates the treatment of facial cellulitis arising from dens evaginatus with open apex. Calcium hydroxide was used for the apexification procedure. One year after canal obturation, radiography revealed no apical pathosis and the apical seal was evident.

    2012-01-01

    Dens invaginatus is a developmental anomaly resulting from invagination of a portion of crown forming within the enamel organ during odontogenesis. The invagination ranges from a slight pitting (coronal type) to an anomaly occupying most of the crown and root (radicular type). Although a clinical examination may reveal a deep fissure or pit on the surface of an anterior tooth, radiographic examination is the most realistic way to diagnose the invagination. The objective of this case presentation is to report a rare case of radicular dens in dente, which is a rare dental anomaly. PMID:22900211

    2009-01-01

    The endodontic treatment of teeth with dens invaginatus, characterized by an infolding of enamel and dentin, extending deep into the pulp cavity near the root apex, may be complicated and challenging. The complexity of the internal anatomy may create challenges for the complete removal of diseased pulpal tissue and the subsequent sealing of the canal system. Because of the bizarre root canal anatomy and widely open apex, a combination of nonsurgical and surgical endodontic treatment or extraction is the most common choice of therapy. This article describes case reports of nonsurgical endodontic treatment of Type II dens invaginatus associated with periradicular lesion. PMID:20617071

  20. Radicular Dens Invaginatus: Report of a Rare Case

    Directory of Open Access Journals (Sweden)

    V. T. Beena

    2012-01-01

    Full Text Available Dens invaginatus is a developmental anomaly resulting from invagination of a portion of crown forming within the enamel organ during odontogenesis. The invagination ranges from a slight pitting (coronal type to an anomaly occupying most of the crown and root (radicular type. Although a clinical examination may reveal a deep fissure or pit on the surface of an anterior tooth, radiographic examination is the most realistic way to diagnose the invagination. The objective of this case presentation is to report a rare case of radicular dens in dente, which is a rare dental anomaly.

  19. Pulp revascularization of immature dens invaginatus with periapical periodontitis.

    Science.gov (United States)

    Yang, Jie; Zhao, Yuming; Qin, Man; Ge, Lihong

    2013-02-01

    Dens invaginatus is a rare developmental malformation of a tooth caused by the invagination of the tooth crown before biological mineralization occurs. The complex anatomy of these teeth makes nonsurgical endodontic treatment difficult and more so when there is presence of periapical periodontitis with open apex. The endodontic treatment of dens invaginatus is a challenge, especially in the case of periapical periodontitis with open apex. Pulp revascularization is a conservative endodontic treatment that has been introduced in recent years. Presented here is a variant approach for the treatment of immature dens invaginatus type II with periapical periodontitis, which combines filling of the invagination and pulp revascularization. After accessing the pulp chamber, the main canal and the invagination were explored. The root was thoroughly disinfected by irrigating and medication, invagination was filled, and the main canal was revascularized. Then the coronal sealing was made by glass ionomer cement and composite resin. Radiograph taken regularly and computed tomography scan were used to investigate the healing of the periapical lesion and development of the root. In the subsequent follow-up, the periapical lesion was completely eliminated, the open apex was closed, and the wall of the root was thickened. For type II immature dens invaginatus with large periapical lesion, conservative endodontic treatment should be considered before periapical surgery. With sufficient infection control, pulp revascularization can be an effective alternative method. Copyright © 2013 American Association of Endodontists. Published by Elsevier Inc.

    Dens invaginatus may be seen as a developmental malformation. It is characterized by an invagination of the enamel and dentin, creating a lumen inside the affected tooth, which may extend as deep as the apical foramen. Oehlers Type IIIb is considered the most challenging clinical conditions. The purpose of this study is to discuss the nonsurgical endodontic management of vital and necrotic dens invaginatus Type IIIb cases. Due to the complex anatomical consideration of dens invaginatus Type IIIb, endodontic treatment is extremely technique sensitive. A conservative approach was used in a vital case to treat the invaginated lumen only, to preserve the vitality of the pulp, and a more invasive approach was used in a necrotic case to debride the lumen and necrotic pulp for proper disinfection of the root canal system. Although different, all the approaches were successful. The clinical signs and symptoms were resolved. The vital case remains vital after 19 months, and the recall radiographs were able to show satisfactory periapical healing both in vital and necrotic cases. Due to the highly complex anatomy of dens invaginatus Type IIIb, the decision of preserving the pulp vitality may not be related only to pulpal diagnosis but also to the technical requirements of the treatment. Although very technically sensitive, it may be possible to treat the invaginated lumen exclusively, while preserving the vitality of the pulp. Necrotic cases may require a more aggressive approach to achieve a favorable prognosis.

    Calcification around the odontoid process suggests 'crowned dens' syndrome, when accompanied with acute occipital headache or neck pain and with inflammatory signs. We retrospectively searched for calcification around the odontoid process in routine CT images of 282 patients emcompassing the craniovertebral junction, and found 13 (4.6%) had 'crowned dens' calcifications with neither characteristic symptoms nor signs suggestive for crowned dens' syndrome. Females of older ages frequently showed asymptomatic crowned dens' calcifications. (author)

    Full Text Available Four visual censuses targeting Octopus vulgaris living in dens on sandy bottoms were carried out from June to October 2013 in the National Park of the Atlantic Galician Islands (NW Spain. Censuses were undertaken by scuba diving between 5 and 21 m depth in daytime. The total area swept was 13.75 ha. There were no significant differences between octopus presence in dens during open and closed fishing seasons. Depth had a significant negative relationship with occupancy. The average number of dens per 1000 m2 was 3.84±0.84 in June and 3.89 in October. The area per den was 260 m2. Den number estimations varied between 1586 and 2057. The largest number of dens (76.5% was found between 5 and 10 m depth. Den distribution was clumped. No significant differences were found between octopus size classes (small, medium and large and den diameter. Associate dens were observed. There were no significant differences in den diameter and shell types found around the middens. Many dens could be “permanent”. Drilling bivalve shell behaviour is discussed. The surveyed area had around 1100 individuals, mainly small specimens. No significant differences were found between octopus size and depth. Substrate, den type and food abundance and availability (especially razors Ensis arcuatus seem to be the main factors influencing dens and octopus density and distribution. Den availability does not appear to be a limiting factor in this case. Temperature, den availability, predators and fishing pressure influencing density and distribution are discussed. Rodas inlet may be a preferential habitat for O. vulgaris individuals ranging from 200 to 2000 g, but especially small specimens ( ≤ 1000 g.

    Dens invaginatus is a developmental variation in the formation of a tooth that causes changes in the internal anatomy of the tooth. The presence of double dens invaginatus is extremely rare. Understanding the type, extension, and complex morphology of dens invaginatus is essential. Diagnosis of this condition using conventional radiographic techniques is not easy. Advanced imaging techniques, such as cone beam computed tomography (CBCT) are very helpful in diagnosis of these complex anatomic variations. In the present case report, we demonstrate the use of CBCT in the evaluation and treatment planning of bilateral maxillary dens invaginatus, of which one presented as a case of double dens.

    We evaluated selection of den sites by American black bears (Ursus americanus) in the Pisgah Bear Sanctuary, western North Carolina, by comparing characteristics of dens at 53 den sites with availability of habitat characteristics in annual home ranges of bears and in the study area. We also tested whether den-site selection differed by sex, age, and reproductive status of bears. In addition, we evaluated whether the den component of an existing habitat model for black bears predicted where bears would select den sites. We found bears selected den sites far from gravel roads, on steep slopes, and at high elevations relative to what was available in both annual home ranges and in the study area. Den-site selection did not differ by sex or age, but it differed by reproductive status. Adult females with cubs preferred to den in areas that were relatively far from gravel roads, but adult females without cubs did not. The habitat model overestimated the value of areas near gravel roads, underestimated the value of moderately steep areas, and did not include elevation as a predictor variable. Our results highlight the importance of evaluating den selection in terms of both use and availability of den characteristics. ?? 2007 American Society of Mammalogists.

    2015-01-01

    Intensive forest management may influence the availability of suitable den sites for large den-seeking species, such as Procyon lotor (Raccoon). As part of a Raccoon ecology study on an industrial forest in the Allegheny Mountains of central West Virginia, we radio-tracked 32 Raccoons to 175 diurnal den sites to determine relative use of dens that included cavity trees, rock dens, log piles, slash piles, and exposed limbs. Patterns of den use significantly differed between sexes and among seasons. Overall, we recorded 58 cavity dens in 12 tree species with 7 maternal dens found in 5 tree species. Raccoons selected larger-diameter den trees than available cavity trees and non-cavity trees. Because the abundance of suitable tree cavities is known to influence Raccoon densities and recruitment at fine spatial scales and female Raccoons in this study used tree cavities as maternal den sites, the continued harvest of large-diameter trees (i.e., those capable of developing den cavities) without replacement may impact Raccoon recruitment within intensively managed forests throughout the central Appalachians.

    Full Text Available Dens invaginatus is a rare malformation affecting the teeth. The teeth that are most commonly affected are the permanent maxillary lateral incisors. The mandibular posterior teeth are rarely affected by dens invaginatus. In most of the cases, a single dens invaginatus is seen affecting the tooth. Cases of double dens invaginatus affecting a single tooth are rare, and those of triple dens invaginatus in a single tooth are even rarer. Here, we present a case of a 14-year-old where three dens invaginatus were seen in the mandibular second premolar. This is the fourth case of three dens invaginatus in a single tooth as only three have been reported previously.

    Full Text Available Der vorliegende Sammelband basiert auf Vorträgen einer Konferenz aus dem Jahr 1995, auf der nach dem spezifischen Erleben des Holocaust durch Frauen gefragt wurde. In der Regel waren es Zeugnisse von Überlebenden, die die Grundlage für die Analyse von Verhalten und Reaktionen von Frauen bildeten. Diskutiert wurde aber nicht nur über die einzelnen Erfahrungsbereiche jüdischer Frauen in West- und Osteuropa in Zwischenkriegs- und Kriegszeit, sondern ebenso über die Anwendbarkeit der „Gender-Frage“ auf den Holocaust generell. Entstanden ist so ein interessanter Überblick über den aktuellen Stand der Diskussion, der die Grenzen und mehr noch die Chancen eines solchen Zugangs hervortreten läßt.

    This study discusses a nonconventional therapeutic protocol for type III dens invaginatus. This condition is a disorder of dental development, caused by the invagination of enamel into coronal and/or radicular dentin structure. This promotes several structural alterations within the dental organ, which offers challenges and difficulties to perform the endodontic treatment when needed. This article reports a clinical case where a conservative approach was adopted to preserve the invagi-nated tooth, and endodontic treatment was performed in the main necrotic canal. Following 21 years of observation, a complete root formation could be seen, with dental pulp preservation of the pulpotomized tooth. Considering the reported difficulties for the treatment of dens invaginatus, conservative measures, such as pulpotomy to preserve the remaining dental pulp may be an excellent alternative to allow less invasive procedures, thus avoiding endodontic surgery. This study discusses a nonconventional therapeutic protocol for type III dens invaginatus. A conservative approach adopted preserved the invaginated tooth, and root canal treatment was performed in the main necrotic canal. Following 21 years of observation, there was complete root formation, with dental pulp preservation of the pulpotomized tooth.

    The prevalent notion about maxillary central incisor with normal external morphology is a tooth with single root and root canal. A case in which all four maxillary incisors were having Type II canal configurations (Vertucci's classification) is reported, in addition, the lateral incisors revealed dens invaginatus with a Type I pattern as suggested by Ohler's classification and a large periapical lesion was seen in relation to the right lateral incisor. The diagnosis was confirmed with the aid of spiral computed tomography (CT) and canals obturated. Nonsurgical healing of the lesion was assessed by reviewing the case at prefixed intervals of time.

    Full Text Available To avoid predation, octopuses select and actively modify shelters (also called dens in the substratum, where they remain most of the time, especially during daylight hours. The main questions that this study deals with are: Is den availability a significant constraint for the distribution of Octopus vulgaris on soft sediment? What kind of dens does O. vulgaris use on soft sediment and what factors affect the selection of one type instead of another? With population density measurements by SCUBA diving and enrichment experiments with artificial dens, we concluded that the availability of solid materials necessary for den construction is a limiting factor for the distribution of O. vulgaris on soft sediment. O. vulgaris used four different types of den on soft sediment: well (a vertical hole in the sediment, rock/stone (the octopus uses a rock or a large stone to dig a cavity under it, shell (an empty shell is used, human origin (a solid material of human origin is used. The relative proportion of the four types of den in the areas studied was: 38.7% human origin, 29.7% well, 21.5% rock/stone, 2.9% shell. Also, 7.3% of the octopuses were found outside their den. The main types of den were found in different relative proportions in relation to the depth, the distance from shore, the octopus size and the granulometry of the sediment.

    Full Text Available Dens invaginatus is a developmental anomaly resulting from epithelial invagination of the tooth crown before calcification. Endodontic treatment of teeth affected by dens invaginatusmay be difficult and complex due to aberrant anatomy. Combined orthograde and surgical approaches for successful treatment of dens invaginatus are effective. This report describes the successful treatmentand results atthe 12-month follow-up of a maxillary lateral incisor showing dens invaginatus type II, a large periapical lesion and an open apex by using combined surgical and endodontic treatment.

    To assess the prevalence and type of dens invaginatus in anterior teeth of a selected population and to report associated dental complications. The records of patients examined in the Department of Paedodontics, Faculty of Dentistry, Süleyman Demirel University, Isparta, Turkey between 1999 and 2006 were screened and a total of 2477 patients who had complete records with satisfactory radiographs were selected. The type of dens invaginatus and the presence of apical pathosis was determined from radiographs. Other dental abnormalities, syndromes and systemic diseases were noted. Variations in crown shape were also recorded. Dens invaginatus was detected in 300 out of 2477 patients, with a prevalence of 12%; 82% of affected patients had dens invaginatus bilaterally. Maxillary lateral incisors were the most affected teeth. The majority of the teeth had normal crown morphology (95%). The most commonly seen type of dens invaginatus was type I (94%). Overall 33% of the patients with type III dens invaginatus and 4% of the patients with type II dens invaginatus had apical pathosis. No associations with other systemic diseases and syndromes and some limited association with hypodontia and dens evaginatus were detected. A careful oral examination, radiographs, a suitable treatment plan and follow-up programme are crucial for early diagnosis and treatment for teeth with dens invaginatus.

For Kant findes der rene videnskaber og empiriske videnskaber. De rene videnskabers begreber er karakteriseret...... instrumentalisme, der hersker. Der er visse subjektive principper og maximer, som er mere ’naturlige’ og ’rigtige’ end andre.

It is an important dental anomaly due to the possible pulpal involvement. DI can be detected clinically in a tooth presenting unusual crown morphology or having deep foramen coaceum. Also, clinically, non-suspected affected teeth are commonly diagnosed as an incidental radiographic finding. Presence of DI in the mandibular premolar teeth is unusual. Aims is to introduce a case of bilateral occurrence of DI in mandibular first premolar teeth. A 33- year-old man was referred to our clinic with a chief complaint of severe pain in his lower third molar tooth. Radiographic examination revealed bilateral DI (single at the left, double at the right in mandibular first premolar teeth. The teeth were restored with fissure sealant. Although bilateral appearance of DI is a frequent situation, mandibular occurrence is very rare. Our review of the literature reveals just nine cases of DI, and only one of them is in a premolar tooth.

    2007-01-01

    We observed polar bear (Ursus maritimus) maternity den sites on Alaska’s North Slope in March 2002 and 2003 in an effort to describe bears’ post-den emergence behavior. During 40 sessions spanning 459 h, we observed 8 adults and 14 dependent cubs outside dens for 37.5 h (8.2% of total observation time). There was no significant difference between den emergence dates in 2002 (mean = 15 Mar ± 4.1 d) and 2003 (mean = 21 Mar ± 2.1 d). Following initial den breakout, polar bears remained at their den sites for 1.5 to 14 days (mean = 8.1 ± 5.1 d). The average length of stay in dens between emergent periods was significantly shorter in 2002 (1.79 h) than in 2003 (4.82 h). While outside, adult bears were inactive 49.5% of the time, whereas cubs were inactive 13.4% of the time. We found no significant relationships between den emergence activity and weather. Adult polar bears at den sites subjected to industrial activity exhibited significantly fewer bouts of vigilance than denned bears in undisturbed areas (t = -5.5164, df = 4, p= 0.00). However, the duration of vigilance behaviors at sites near industrial activity was not significantly shorter than at the other sites studied (t = -1.8902, df = 4, p = 0.07). Results for these bears were within the range of findings in other studies of denned polar bears.

The question is discussed of whether the resulting lowering of the carbon dioxide concentration on a global scale could be a solution to the greenhouse problem.

    Activity of Swift Foxes (Vulpes velox) at den sites was studied in northwestern Texas during pup rearing seasons in 2000 and 2001 to determine role of males in parental care. Twenty-four percent of radio-collared females with a potential to breed successfully raised pups to eight weeks of age. We intensively monitored presence and absence of male and female Swift Foxes at two den sites each year. Females were present >2.6 times more at den sites than males during the pup rearing season. Female and male Swift Foxes largely stayed at dens during diurnal hours and were active away from dens during nocturnal and crepuscular hours. Females and males spent 12.4% and 3.0% more time at dens before pups emerged, than after pups emerged, respectively. Following depredation of one male parent, the female spent 29% less time at the den site. Decrease in time spent at the den by the female following loss of her mate suggested that loss of one parent might severely impact recruitment of Swift Foxes. Our observations indicated that intense Coyote (Canis latrans) depredation may severely impact pup-rearing success as well as the parental care within Swift Fox family groups.

    2006-01-01

    Polar bears (Ursus maritimus) give birth during mid-winter in dens of ice and snow. Denning polar bears subjected to human disturbances may abandon dens before their altricial young can survive the rigors of the Arctic winter. Because the Arctic coastal plain of Alaska is an area of high petroleum potential and contains existing and planned oil field developments, the distribution of polar bear dens on the plain is of interest to land managers. Therefore, as part of a study of denning habitats along the entire Arctic coast of Alaska, we examined high-resolution aerial photographs (n = 1655) of the 7994 km2 coastal plain included in the Arctic National Wildlife Refuge (ANWR) and mapped 3621 km of bank habitat suitable for denning by polar bears. Such habitats were distributed uniformly and comprised 0.29% (23.2 km2) of the coastal plain between the Canning River and the Canadian border. Ground-truth sampling suggested that we had correctly identified 91.5% of bank denning habitats on the ANWR coastal plain. Knowledge of the distribution of these habitats will help facilitate informed management of human activities and minimize disruption of polar bears in maternal dens.

    Dens invaginatus is a rare developmental anomaly. It is unusual to find this anomaly in primary dentition. Diagnosis of this dens invaginatus is important due to possible pulpal involvement. Not only that, simultaneous presence of other dental anomaly may require long-term treatment planning. Dens invaginatus can be detected clinically in the tooth presenting unusual crown morphology or radiographically as radiopacity within tooth. This article describes one of the first case reports of dens invaginatus in primary maxillary second molar in a 5-year-old female patient.

Results indicate that this rodent uses holes in the ground or in fallen trees as sleeping dens. Each of these sleeping dens had two or more orifices and an internal cavity for the "diurnal sleep”. Typically, one orifice was for common use and the rest for the circumstantial escape. According to their form, their localization in the ground, and the number and location of orifices, sleeping dens were classified into four types, of which type A was the most common. The results also indicate a greater concentration of sleeping dens in temporary flooded gallery forest.

  10. Dens invaginatus in an impacted mesiodens: a morphological study.

    Science.gov (United States)

    Cantín, M; Fonseca, G M

    2013-01-01

    Dens invaginatus (DI) is a dental anomaly originated from invagination of the enamel organ into the dental papilla, during odontogenesis. DI may be associated with other abnormalities such as dysmorphic mesiodens, and this unusual condition may be detected by chance on the conventional radiography. However, the three-dimensional nature and the exact morphological patterns of DI are impossible to appreciate from this method. We present a morphological study of impacted mesiodens in a 9-year-old girl, which the three coronal invaginations were detected only by Cone-Beam Computed Tomography (CBCT) in the pre-surgical examination. CBCT, radiographic and microscopic reproductions allow transfer of images to facilitate cooperation of working groups, examination as well as for teaching purposes.

    2015-01-01

    Dens invaginatus (DI) and gemination are two developmental abnormalities that are well reported in the dental literature, but their coexistence in a single tooth is rare. Such situations worsen the risk factors associated with these anomalies, and the treatment plan should be customised as they possess altered morphology and anatomy. A 19-year-old girl came for evaluation of a cracked tooth in the front region of the upper jaw. The tooth showed clinical features of gemination and radiographic features of DI, and was diagnosed as DI in geminated maxillary lateral incisor. The differential diagnoses based on clinical appearance without radiographic investigation may warrant the treatment approach if these two abnormalities coexist in a single tooth. The report also highlights the importance of three-dimensional imaging in diagnosis and treatment planning of teeth with altered pulp canal anatomy. There are few reported cases in the literature detailing the treatment options for these two anomalies occurring in the same tooth. PMID:26002668

    We examined eight summer dens (used only in summer) and seven hibernacula (occupied both in winter and summer) of the snake Pituophis melanoleucus in the New Jersey Pine Barrens, comparing above ground characteristics of hibernacula and summer dens with characteristics at nearby random points. Temperatures at the soil surface and at 10 cm depth were significantly warmer, and there was less leaf cover around the random points compared to the entrances of the hibernacula and summer dens. Hibernacula had significantly more vegetation cover within 5 m, more leaf cover over the burrow entrance, and were closer to trees than were summer dens. Most hibernacula and summer dens were beside old fallen logs (73%), the entrance tunnels following decaying roots into the soil. Excavation of the hibernacula and summer dens indicated that most hibernacula appeared to be dug by the snakes and had an average of eight side chambers and 642 cm of tunnels, compared to less than one side chamber and 122 cm of tunnels for summer dens. Except for hatchlings, most snakes in hibernacula were located in individual chambers off the main tunnel; all snakes were at depths of 50-111 cm (X̄ = 79 cm). Pine snakes may select optimum hibernation sites which reduce winter mortality.

    Increasing winter use of steep, high-elevation terrain by backcountry recreationists has elevated concern about disturbance of denning grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem (GYE). To help identify areas where such conflicts might occur, we developed a spatially explicit model to predict potential denning areas in the GYE. Using a scan area of 630 m around each location, we assigned site attributes to 344 den locations of radio-trackedg rizzly bears from 1975-99. Attributesi dentified as predictorsf or the analysis included elevation, slope, an index of solar radiation, and forest cover. We used the Mahalanobis distance statistic to model the similarity between sites used by denning bears and each cell in the data layers. We used the final Mahalanobis distance model to produce maps of the study area. Potential denning habitat, based upon the model, is abundantw ithin the GYE. Ourr esultsc an be used by land managementa gencies to identifyp otentialc onflict sites and minimize effects of regulated activities on denning grizzly bears. We illustrate how the Gallatin National Forest (GNF) used the model to examine the overlap between potential snowmobile use areas and potential denning habitat as part of a Biological Assessment submitted to the U.S. Fish and Wildlife Service.

    Full Text Available Aim: The aim of this study was to determine the prevalence of dens invaginatus in a sample of Turkish dental patients. Materials and Methods: The sample included 6, 912 panoramic radiographs from different Turkish dental patients. The ages of the patients ranged from 18 to 50 years. A tooth was considered having dens invaginatus if an infolding of a radiopaque ribbon-like structure equal in density to enamel was seen extending from the cingulum into the root canal. Maxillary and mandibular teeth were evaluated on panoramic radiographs to determine the type of dens invaginatus using Oehlers′ classification. Results: The overall incidence of patients with dens invaginatus was 0.17%. Dens invaginatus were detected in 15 teeth of a total of 192 150 teeth to give a tooth prevalence of 0.008%. Maxillary lateral incisors were most commonly affected teeth in the mouth (80% of cases, followed by maxillary canine teeth (20% of cases. The bilateral incidence of a symmetrical distribution was 25%. Conclusion: The occurrence of dens invaginatus among this Turkish population was rare. Attention should be paid to the presence of dens invaginatus and the treatment problems associated with it.

    The objective of this study was to assess the prevalence and characteristics of dens invaginatus in anterior teeth and to classify the type of dens invaginatus in a sample of Turkish Anatolian population. A retrospective study was performed using full-mouth periapical and panoramic radiographs of 1012 patients. Maxillary and mandibular anterior teeth were evaluated for the presence and characteristics of dens invaginatus. Statistical evaluation of the presence of dens invaginatus related to gender was performed by the Pearson chi-squared test. Dens invaginatus was observed in 13 out of 1012 subjects and in only maxillary lateral incisors. There were no periapical lesions in teeth with types I and II, whereas both of the subjects with type III had apical periodontitis at the time of referral. Males and females were equally affected by dens invaginatus (P=0.98). The anomaly was detected in only maxillary lateral incisors with no gender difference and the most commonly observed type of dens invaginatus was type I (81.25%).

    Dentatin (DEN), purified from the roots of Clausena excavata Burm f., has poor aqueous solubility that reduces its therapeutic application. The aim of this study was to assess the effects of DEN-HPβCD (hydroxypropyl-β-cyclodextrin) complex as an anticancer agent in HT29 cancer cell line and compare with a crystal DEN in dimethyl sulfoxide (DMSO). The exposure of the cancer cells to DEN or DEN-HPβCD complex leads to cell growth inhibition as determined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. To analyze the mechanism, in which DEN or DEN-HPβCD complex causes the death in human colon HT29 cancer cells, was evaluated by the enzyme-linked immunosorbent assay (ELIZA)-based assays for caspase-3, 8, 9, and reactive oxygen species (ROS). The findings showed that an anti-proliferative effect of DEN or DEN-HPβCD complex were via cell cycle arrest at the G2/M phase and eventually induced apoptosis through both mitochondrial and extrinsic pathways. The down-regulation of poly(ADP-ribose) polymerase (PARP) which leaded to apoptosis upon treatment, was investigated by Western-blotting. Hence, complexation between DEN and HPβCD did not diminish or eliminate the effective properties of DEN as anticancer agent. Therefore, it would be possible to resolve the conventional and current issues associated with the development and commercialization of antineoplastic agents in the future.

    Full Text Available Dens in dente, also known as dens invaginatus, dilated composite odontoma, or deep foramen caecum, is a developmental malformation that usually affects maxillary incisor teeth, particularly lateral incisors. It may occur in teeth anywhere within the jaws, other locations are comparatively rare. It can occur within both the crown and the root, although crown invaginations are more common. The use of cone beam computed tomography (CBCT is very helpful in endodontic diagnosis of complex anatomic variations. In this case we demonstrate the use of CBCT in the evaluation and endodontic management of a Type III dens in dente (Oehler′s Type III.

    Dens invaginatus occurs as a result of the invagination of the enamel organ. These cases may present difficulties with respect to its diagnosis and treatment because of canal morphology. It frequently leads to caries, pulpal, and periodontal involvement with necrosis and loss of attachment. The knowledge of classification and anatomical variations of teeth with dens invaginatus are of great importance for correct treatment. This article presents two case reports of two different types of dens invaginatus along with profound review of the literature regarding etiology, epidemiology, and histology. It discusses clinical appearance and diagnosis, and it provides guidelines for decision-making and treatment of invaginated teeth. PMID:24678234

    Dens invaginatus is a developmental dental anomaly clinically characterized by a palatine furrow that can be limited to the coronal pulp or may extend to the radicular apex. The purpose of this paper was to present a clinical case of type III dens invaginatus, identified on the maxillary right central incisor in anterior periapical radiographs, in which the tooth was submitted to conventional endodontic treatment. The results obtained after five years of clinical and radiographic followup demonstrated that conventional endodontic treatment is a clinically viable alternative in cases of type III dens invaginatus.

    Full Text Available Though a clinical examination may reveal a deep fissure or pit on the surface of an anterior tooth, radiographic examination is a more accurate approach to diagnose an invagination. Dens invaginatus is one of the common dental deformities, but the defect involving the root and its association with radicular cyst is still very uncommon. The objective of this case presentation is to report a case of radicular dens in dente, which is a rare dental anomaly. This case report shows that dens invaginatus with an open apex and a radicular cyst can be treated successfully using currently available materials.

    Dens invaginatus (DI) and gemination are two developmental abnormalities that are well reported in the dental literature, but their coexistence in a single tooth is rare. Such situations worsen the risk factors associated with these anomalies, and the treatment plan should be customised as they possess altered morphology and anatomy. A 19-year-old girl came for evaluation of a cracked tooth in the front region of the upper jaw. The tooth showed clinical features of gemination and radiographic features of DI, and was diagnosed as DI in geminated maxillary lateral incisor. The differential diagnoses based on clinical appearance without radiographic investigation may warrant the treatment approach if these two abnormalities coexist in a single tooth. The report also highlights the importance of three-dimensional imaging in diagnosis and treatment planning of teeth with altered pulp canal anatomy. There are few reported cases in the literature detailing the treatment options for these two anomalies occurring in the same tooth. 2015 BMJ Publishing Group Ltd.

    2012-01-01

    Mesiodens is a supernumerary tooth occupying the position in the maxillary anterior region. This additional tooth structure may cause disturbance in eruption or position of the adjacent teeth. About 8–25% of supernumerary teeth in the anterior region erupt spontaneously. Un-erupted supernumerary teeth are incidentally identified on a routine radiographic examination. Dens invaginatus is a rare tooth malformation showing an in-folding of enamel and dentine of affected tooth sometimes extending deep into the pulp cavity and the root portion. We report a case of un-erupted mesiodens causing midline diastema of permanent teeth subsequently corrected following extraction of mesiodens. Dens invaginatus was identified affecting the un-erupted mesiodens. It is rare to find dens invaginatus associated with a supernumerary tooth and only 10 such instances of dens invaginatus affecting supernumerary teeth have been reported in the English literature.

  16. Remote identification of maternal polar bear (Ursus maritimus) denning habitat on the Colville River Delta, Alaska

    Science.gov (United States)

    Blank, Justin J.

    High resolution digital aerial photographs (1 foot pixel size) of the Colville River Delta, Alaska were examined in 3D, with the use of a digital photogrammetric workstation. Topographic features meeting the criteria required for adequate snow accumulation, and subsequent construction of terrestrial polar bear maternal dens, were identified and digitized into an ArcGIS line shapefile. Effectiveness, efficiency, and accuracy were improved when compared to previous polar bear denning habitat efforts which utilized contact photo prints and a pocket stereoscope in other geographic areas of northern Alaska. Accuracy of photograph interpretation was systematically evaluated visually from the air with the use of a helicopter and physically on the ground. Results show that the mapping efforts were successful in identifying den habitat 91.3% of the time. Knowledge denning habitat can improve and inform decision making by managers and regulators when considering travel and development in the study area. An understanding of polar bear denning habitat extent and location will be a crucial tool for planning activities within the study area in a way that minimizes conflicts with maternal dens.

    2008-10-01

    To report the endodontic treatment of an immature maxillary central incisor with dens invaginatus. Dens invaginatus is a rare malformation of teeth, probably resulting from an infolding of the dental papilla during tooth development. The present case describes the complex endodontic treatment of a type III dens invaginatus in an immature maxillary central incisor with a necrotic pulp and abscess formation. The initial treatment goal was to achieve apexification of the pseudocanal root and conservative root canal treatment in the main canal. Following 1-year of treatment with calcium hydroxide dressings, radiography revealed a healing response, but no sign of a hard tissue barrier at the apex. Periapical surgery with the placement of a zinc oxide cement (IRM) root-end filling was considered successful at the 4-year follow-up. The complexity of the canal system and open apex in dens invaginatus present a challenge to endodontic treatment. Correct diagnosis and treatment planning are fundamental to treatment of dens invaginatus. Periapical surgery is indicated in cases of unsuccessful apexification in immature teeth with dens invaginatus and nonvital pulp.

    Dens invaginatus is a developmental anomaly that often presents a perplexing challenge to the endodontist. It involves the maxillary central incisor less commonly than the maxillary lateral incisor. Double dens invaginatus is even rarer. Herein a unique case of dens invaginatus in a maxillary central incisor is presented. The tooth had an inadequate previous root canal treatment. On retreatment, multiple canals and double dens invaginatus were found. The invaginations were Oehlers type 3b and type 2. The complex morphology was diagnosed and confirmed with cone-beam computed tomography imaging and managed with a combined surgical and orthograde approach. Four canals and a blind sac along with an open apex were found. There were many intercommunications between the canals. During the treatment, a complication of a separated instrument occurred, which was managed successfully. The 1-year follow-up shows successful outcome of the treatment. Dens invaginatus may be more complicated than it seems. It needs meticulous treatment by a specialist. Failure or a delay in referring the case to a specialty setting may further increase the complications. With the advancements in equipment and materials, it is possible to save even severe cases of dens invaginatus. Copyright © 2015 American Association of Endodontists. Published by Elsevier Inc.

    The purpose of this study was to assess the prevalence of dens invaginatus and to classify the types of dens invaginatus in a sample of the Turkish population. A retrospective study was performed using periapical and panoramic radiographs of 5355 patients who presented to the Department of Oral Diagnosis and Radiology at the Ondokuz Mayis University Dentistry Faculty between January 2009 and December 2010. Maxillary and mandibular anterior teeth were evaluated for the presence and characteristics of dens invaginatus. Statistical evaluation of the presence of dens invaginatus related to gender was performed by the Pearson chi-squared test. Dens invaginatus was observed in 116 of 4556 subjects, with a frequency of 2.5%. There was only one periapical lesion in teeth with type I dens invaginatus, but 8.1% of patients with type II and 87.5% of patients with type III dens invaginatus had apical periodontitis at the time of referral. There were 116 (72%) females and 32 (27%) males with dens invaginatus. This data represents the only study carried out in a large population in Turkey, and no dens invaginatus was found in mandibular teeth. The most commonly observed type of dens invaginatus was type I (69.8%).

  20. Heading for the hills: risk avoidance drives den site selection in African wild dogs.

    Directory of Open Access Journals (Sweden)

    Craig R Jackson

    Full Text Available Compared to their main competitors, African wild dogs (Lycaon pictus have inferior competitive abilities and interspecific competition is a serious fitness-limiting factor. Lions (Panthera leo are the dominant large carnivore in African savannah ecosystems and wild dogs avoid them both spatially and temporally. Wild dog young are particularly vulnerable and suffer high rates of mortality from lions. Since lions do not utilize all parts of the landscape with an equal intensity, spatial variation in lion densities can be exploited by wild dogs both during their general ranging behaviour, but more specifically when they are confined to a den with vulnerable young. Since patches of rugged terrain are associated with lower lion densities, we hypothesized that these comparatively safe habitats should be selected by wild dogs for denning. We investigated the relationship between the distribution of 100 wild dog den sites and the occurrence of rugged terrain in four wild dog populations located in Tanzania, Zimbabwe and South Africa. A terrain ruggedness index was derived from a 90 m digital elevation model and used to map terrain ruggedness at each site. We compared characteristics of actual and potential (random den sites to determine how wild dogs select den sites. The distributions of wild dog dens were strongly associated with rugged terrain and wild dogs actively selected terrain that was more rugged than that available on average. The likelihood of encountering lions is reduced in these habitats, minimizing the risk to both adults and pups. Our findings have important implications for the conservation management of the species, especially when assessing habitat suitability for potential reintroductions. The simple technique used to assess terrain ruggedness may be useful to investigate habitat suitability, and even predict highly suitable denning areas, across large landscapes.

    There are many developmental variations in the permanent dentition. Dens invaginatus can be recognized on many dental X-rays of affected patients, but not every image allows for assessment of the type of malformation. The aim of the present study was to assess the presence of dens invaginatus with radiological features using cone-beam computed tomography (CBCT). CBCT images of 33 patients were evaluated. Age, sex, side, lateralization, occurrence in a particular group of teeth, type of invagination, differentiation, and the consequences of these factors were analyzed. Forty-one teeth with dens invaginatus met the inclusion criteria for this evaluation. Females were affected more frequently than males (57.6 vs. 42.4%, respectively). The patients' age ranged from 7 to 40 years, and the occurrence of dens invaginatus peaked from age 9 to 13 years. In total, 92.7% of affected teeth were present in the maxilla, more often unilaterally (75.8%) than bilaterally (24.2%). The most frequent tooth with dens invaginatus was the maxillary lateral incisor (53.7% of affected teeth). Almost two-thirds (63.4%) of affected teeth were found on the left side and 36.6% were found on the right. The tooth anatomy was distorted within the crown and root. Dens invaginatus sometimes affected other surrounding teeth and reduced their esthetics. The obtained data indicate that CBCT examination is an essential tool in assessing dens invaginatus and can guide dental practitioners in treating patients who exhibit characteristic features of this disorder. CBCT allows the clinician to distinguish the type of anomaly.

We define the term ‘naturalism’ and explain, in which way naturalistic attitudes may occur and which questions they are related to. Based on a theological and philosophical criticism of naturalism we want to encourage teachers of religion to openly question such worldviews. To do so, we refer to the concept of ‘philosophy/theology for children/adolescents’. We argue to use the so-called ‘Socratic Method’ in its original sense, namely the challenging of alleged certainties (elenchus. The Socratic Method can and should be used not only to philosophize freely, but also to question pupils’ (naturalistic worldviews and attitudes, not with the purpose to then impose a ‘correct’ worldview onto them, but to help deconstructing alleged certainties and opening new horizons of thought.

    Dens in dente, also known as dens invaginatus and dilated compound odontoma, is a malformation that can occur on primary, permanent, or supernumerary teeth that is characterized by a deep invagination of the surface of a crown or root covered with enamel. This abnormality in tooth morphology generally affect the maxillary lateral incisors but several cases of multiple dens invaginatus have been reported in the literature. A 15 year-old female patient is reported here presenting five dens invaginatus: four in the permanent mandibular incisors and one in the permanent, maxillary left central incisor, additionally the following dental findings were observed: a permanent mandibular left mulberry molar, molarization of some premolars, several microdontic conoid teeth, retention of five primary teeth, absence of several permanent teeth germs, a macrodontic molar with abnormal roots and several periapical radiolucencies associated to the dens invaginatus. There was no family history of similar dental findings to those observed in the patient. There are several genes that participate in the development of teeth, of those, the following five genes could be implicated as responsible or co-participators for some of the dental anomalies present in this patient: MSX1 (Muscle segment homeobox 1), DLX1 & DLX2 (Distal-less homeobox 1 & 2 genes), PAX9 (Paired box gene) and PITX2 (Pituitary homeobox transciption factor 2).

    To give an overview of treatment options for dens invaginatus based on a classification system. Dens invaginatus is a dental malformation which may give endodontic complications. Treatment may vary in relation to anatomy, and a classification system for dens invaginatus forms the basis for discussion. A clinical case, classified as a type II invagination (Oehlers' classification), is also presented. Clinical and radiographic examination revealed an invagination penetrating into the apical third of the root canal in tooth number 12. The tooth was immature with an open apex, apical pathosis and a labial fistula. To control the infection, ultrasonic removal of the invagination was necessary, as the invagination prevented complete cleaning and shaping of the root canal. After chemo-mechanical preparation and dressing with calcium hydroxide, an apical plug of MTA was placed, followed by restoration of the tooth with resin-bonded composite. Healing of the lesion with hard tissue formation was confirmed at follow-up. KEY LEARNING POINTS * Knowledge about classification and anatomical variations of teeth with dens invaginatus is important in endodontic decision making. * A classification system may be helpful when treatment options are considered. * Classification of dens invaginatus requires a thorough preoperative radiographic examination.

    Dens invaginatus is a rare developmental anomaly of teeth with complex root canal system morphology. The present case describes a peg shape maxillary lateral incisor with dens invaginatus (Oehlers type II), necrotic pulp, and an associated large periradicular lesion. Nonsurgical endodontic treatment was performed with the aim of removing the blind sac with diamond bur under the use of operating surgical microscope. The root canal system was obturated with thermoplastic technique. Final restoration was done using composite. The 20-months clinical and radiological follow up revealed an asymptomatic tooth with healing of the periapical pathology; however, for complete healed periradicular lesion more follow up is needed. This case illustrated that a dens invaginatus malformed teeth with a large periradicular lesion can be managed successfully with nonsurgical root canal therapy (NSRCT).

    Dens invaginatus is a developmental anomaly resulting in a deepening or invagination of the enamel organ into the dental papilla prior to calcification of the dental tissues. The prevalence has been reported to vary from 0.04% to 10%. Dens invaginatus commonly affects lateral incisors and very rarely affects the mesiodens. This article presents a rare case of type II dens invaginatus affecting an impacted mesiodens in a 13-year-old boy and describes its gross and histological features. The associated tooth was dilated and showed invaginated enamel and dentin extending beyond the cement enamel junction. In this case, the clinical diagnosis was confirmed by histological evaluation of the internal morphology using a hard tissue microtome to section the tooth.

    This work describes a case of "dens invaginatus" and analyzes the possible aspects of this malformation. An unusual type of dens invaginatus was detected in a young patient corresponding to the maxillary lateral incisor and showing extensive periradicular radiolucency and a vestibular fistula. The radiographic and tomographic examination revealed two apices: one wide open in the distal part of the root and the other normally formed in the mesial. Nonsurgical endodontic treatment was performed by using the "one-step apexification technique," filling both apexes with mineral trioxide aggregate followed by composite resin. The follow-up examination 6 months later showed the healing of the radiolucent area and the healing of the sinus tract. Hypotheses on which was the type of dens invaginatus we had to deal with are formulated.

  14. Mapping polar bear maternal denning habitat in the National Petroleum Reserve -- Alaska with an IfSAR digital terrain model

    2013-01-01

    The National Petroleum Reserve–Alaska (NPR-A) in northeastern Alaska provides winter maternal denning habitat for polar bears (Ursus maritimus) and also has high potential for recoverable hydrocarbons. Denning polar bears exposed to human activities may abandon their dens before their young are able to survive the severity of Arctic winter weather. To ensure that wintertime petroleum activities do not threaten polar bears, managers need to know the distribution of landscape features in which maternal dens are likely to occur. Here, we present a map of potential denning habitat within the NPR-A. We used a fine-grain digital elevation model derived from Interferometric Synthetic Aperture Radar (IfSAR) to generate a map of putative denning habitat. We then tested the map’s ability to identify polar bear denning habitat on the landscape. Our final map correctly identified 82% of denning habitat estimated to be within the NPR-A. Mapped denning habitat comprised 19.7 km2 (0.1% of the study area) and was widely dispersed. Though mapping denning habitat with IfSAR data was as effective as mapping with the photogrammetric methods used for other regions of the Alaskan Arctic coastal plain, the use of GIS to analyze IfSAR data allowed greater objectivity and flexibility with less manual labor. Analytical advantages and performance equivalent to that of manual cartographic methods suggest that the use of IfSAR data to identify polar bear maternal denning habitat is a better management tool in the NPR-A and wherever such data may be available.

    Dens invaginatus is a developmental anomaly that results in an enamel-lined cavity intruding into the crown or root before the mineralization phase. It typically affects permanent maxillary lateral incisors, central incisors, and premolars. This paper describes the root canal treatment of Oehlers' type II dens invaginatus in maxillary left lateral incisors. A 16-year-old boy presented to the Faculty of Dentistry, University of Kocaeli, to receive his dental treatments. During the caries removal, the pulp was exposed then anendodontic treatment was initiated. Two canals, one of which represented the invagination, were instrumented, irrigated, and then obturated with a lateral condensation technique. PMID:23213576

    Supernumerary teeth are defined as any teeth in excess of normal number. Mesiodens is a supernumerary tooth, in the central region of premaxilla between two central incisors. Dens invaginatus is a developmental anomaly resulting from invagination in the surface of tooth crown before calcification has occurred. Radiographically, it is observed as infolding of a radioopaque ribbon like structure, with equal density as enamel, extending from cingulum into a root canal and sometimes reaching the root apex. This paper aims to present a rare association of dens invaginatus with two mesiodentes in a child causing the eruption disturbance and unaesthetic appearance in anterior maxilla. PMID:23198162

    Full Text Available Gemination is a developmental anomaly where a single tooth bud attempts to split into two. It is also sometimes called as double tooth or twinning. Dens invaginatus is another developmental anomaly caused due to invagination of a portion of crown. These anomalies occur as separate entities. Co-occurrence of these two anomalies have been only reported four times in the literature. Here we present an extremely rare case of simultaneous occurrence of gemination and dens invaginatus in the same tooth. [Cukurova Med J 2016; 41(1.000: 175-177

    Dens invaginatus is a well-recognized phenomenon, and its endodontic treatment poses a challenge, especially for peri-invagination lesions with vital pulp. Here we describe the outcome of conservative treatment and follow-up in a case of type III dens invaginatus. Cone-beam computed tomography was used for diagnosis and follow-up. Pulp vitality was preserved with endodontic treatment of only an invaginated canal. At the 24-month follow-up examination, the tooth was asymptomatic and repair of the lesion was evident radiographically. This case was managed successfully with endodontic treatment of the invagination. (J Oral Sci 56, 307-310, 2014).

    In this study, a serotype-specific monoclonal antibody (mAb), D(2) 16-1 (Ab4), against dengue virus type 2 (DEN-2) was generated. The specificity of Ab4, which recognized DEN-2 non-structural protein 1, was determined by ELISA, immunofluorescence and immunoblotting analyses. The serotype-specific B-cell epitope of Ab4 was identified further from a random phage-displayed peptide library; selected phage clones reacted specifically with Ab4 and did not react with other mAbs. Immunopositive phage clones displayed a consensus motif, His-Arg/Lys-Leu/Ile, and a synthetic peptide corresponding to the phage-displayed peptide bound specifically to Ab4. The His and Arg residues in this epitope were found to be crucial for peptide binding to Ab4 and binding activity decreased dramatically when these residues were changed to Leu. The epitope-based synthetic peptide not only identified serum samples from DEN-2-immunized mice and rabbits by ELISA but also differentiated clearly between serum samples from DEN-2- and Japanese encephalitis virus-immunized mice. This mAb and its epitope-based peptide antigen will be useful for serologic diagnosis of DEN-2 infection. Furthermore, DEN-2 epitope identification makes it feasible to dissect antibody responses to DEN and to address the role of antibodies in the pathogenesis of primary and secondary DEN-2 infections.

    The chimeric yellow fever (YF) 17D-dengue type 2 (ChimeriVax-DEN2) vaccine virus developed by Acambis, Inc. (Cambridge, MA) contains the prM and E genes of wild-type (wt) dengue 2 (DEN-2) (strain PUO-218) virus in the YF vaccine virus (strain 17D) backbone. The potential of ChimeriVax-DEN2 virus to infect and be transmitted by Aedes aegypti, the principal DEN and YF virus mosquito vector, and Aedes albopictus, a species that occurs in areas of active transmission of YF and DEN viruses, was evaluated. Mosquitoes were intrathoracically (IT) inoculated with virus or were fed a virus-laden blood meal, and the replication kinetics of ChimeriVax-DEN2 were compared with the wt DEN-2 and YF 17D vaccine viruses. Replication of YF 17D virus is attenuated in cultured Ae. albopictus C6/36 mosquito cells and in Ae. aegypti and Ae. albopictus mosquitoes. Growth of ChimeriVax-DEN2 virus similarly was restricted in C6/36 cells and in mosquitoes. ChimeriVax-DEN2 replicated in 56% of IT inoculated Ae. aegypti, and virus disseminated to head tissue in 36%, with a mean viral titer of 1.8 log10 PFU/mosquito. Of mosquitoes, 16% of Ae. aegypti and 24% of Ae. albopictus were infected 14 days after a blood meal containing ChimeriVax-DEN2, but virus did not disseminate to head tissue. In contrast, DEN-2 replicated in all IT inoculated and orally infected Ae. aegypti (mean titer 5.5 log10 PFU/mosquito), and virus disseminated to head tissue in 95%. Of Ae. albopictus, 84% were infected after a blood meal containing DEN-2 virus; dissemination occurred in 36%. Replication of ChimeriVax-DEN2 virus in mosquitoes corresponded to that of YF 17D vaccine virus, which is restricted in its ability to infect and replicate in mosquitoes. Therefore, transmission of ChimeriVax-DEN2 virus by vector mosquitoes is unlikely.

  18. The Dens: Normal Development, Developmental Variants and Anomalies, and Traumatic Injuries

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Accurate interpretation of cervical spine imagining can be challenging, especially in children and the elderly. The biomechanics of the developing pediatric spine and age-related degenerative changes predispose these patient populations to injuries centered at the craniocervical junction. In addition, congenital anomalies are common in this region, especially those associated with the axis/dens, due to its complexity in terms of development compared to other vertebral levels. The most common congenital variations of the dens include the os odontoideum and a persistent ossiculum terminale. At times, it is necessary to distinguish normal development, developmental variants, and developmental anomalies from traumatic injuries in the setting of acute traumatic injury. Key imaging features are useful to differentiate between traumatic fractures and normal or variant anatomy acutely; however, the radiologist must first have a basic understanding of the spectrum of normal developmental anatomy and its anatomic variations in order to make an accurate assessment. This review article attempts to provide the basic framework required for accurate interpretation of cervical spine imaging with a focus on the dens, specifically covering the normal development and ossification of the dens, common congenital variants and their various imaging appearances, fracture classifications, imaging appearances, and treatment options.

    There have been few reports of ventilator-induced lung injury associated with noninvasive ventilation (NIV), but many with invasive mechanical ventilation. The purpose of this study was to detect subclinical NIV-associated lung injury by monitoring Krebs von den Lungen glycoprotein plasma levels. Forty-one Duchenne muscular dystrophy patients were divided into three categories: group 1, asymptomatic and not using ventilators; group 2, NIV use less than 24 hrs/day at full ventilatory support settings; and group 3, continuous NIV dependence. Plasma Krebs von den Lungen glycoprotein level was measured by electrochemical luminescent immunoassay using Krebs von den Lungen glycoprotein antibodies. One-way analysis of variance, followed by the Tukey-Kramer test, was used as appropriate to compare intergroup differences. Extent of ventilator dependence correlated with age (P Krebs von den Lungen glycoprotein levels were not significantly different. NIV used at volumes and pressures of full (invasive) ventilatory support may not induce the alveolar septal barrier injury commonly seen with invasive mechanical ventilation.

    Dengue virus (DENV) is a human pathogen and its etiology has been widely established. There are many interactions between DENV and human proteins that have been reported in literature. However, no publicly accessible resource for efficiently retrieving the information is yet available. In this study, we mined all publicly available dengue–human interactions that have been reported in the literature into a database called DenHunt. We retrieved 682 direct interactions of human proteins with dengue viral components, 382 indirect interactions and 4120 differentially expressed human genes in dengue infected cell lines and patients. We have illustrated the importance of DenHunt by mapping the dengue–human interactions on to the host interactome and observed that the virus targets multiple host functional complexes of important cellular processes such as metabolism, immune system and signaling pathways suggesting a potential role of these interactions in viral pathogenesis. We also observed that 7 percent of the dengue virus interacting human proteins are also associated with other infectious and non-infectious diseases. Finally, the understanding that comes from such analyses could be used to design better strategies to counteract the diseases caused by dengue virus. The whole dataset has been catalogued in a searchable database, called DenHunt (http://proline.biochem.iisc.ernet.in/DenHunt/). PMID:27618709

    2014-01-01

    Introduction. "Dens invaginatus" is a dental anomaly which originates from the invagination of the ameloblastic epithelium into the lingual surface of the dental crown during the odontogenesis. It can cause early pulpal necrosis, abscesses, retention or dislocation of contiguous elements, cysts, and internal resorptions. It normally affects the upper lateral incisors. In the following study the authors will discuss the etiology, the physiopathology, and the surgical-orthodontic management of a rare case of impacted canine associated with dens invaginatus and follicular cyst, with the aim of highlighting the importance of taking any therapeutic decision based on the data available in the literature. Case Report. The present study describes a combined surgical-orthodontic treatment of an impacted canine associated with a lateral incisor (2.2) suffering from type III dens invaginatus with radicular cyst, in a 15-year-old patient. Discussion. When treating a dens invaginatus there are different therapeutic solutions: they depend on the gravity of the anomaly and on the association with the retention of a permanent tooth. The aesthetic and functional restoration becomes extremely important when performing a surgical-orthodontic repositioning.

    Dens invaginatus is a critical condition for endodontic treatment once it frequently presents a complex internal anatomy and might be associated with incomplete root and apical development. Three cases of dens invaginatus with open apex in maxillary lateral incisors are presented. In the first case, apexification with calcium hydroxide pastes was performed. In the second case, initial treatment was carried out, but the patient missed follow-up appointments for 15 months. In the third case, periradicular surgery was done as a result of the persistence of exudates and incomplete root canal development after conservative endodontic treatment. Oehlers' type I dens invaginatus was also present in the opposite maxillary lateral incisor in 2 patients, but no treatment was required. At subsequent follow-up, the periradicular region was completely healed, and postoperative radiographs revealed good bone healing in all patients. Patient #2 had an increase in root length, and after 38 months the apical third was completely calcified. A careful clinical and radiographic examination should be conducted to identify dens invaginatus associated with incomplete root development and open apexes. Adequate periradicular healing was observed after the infection, and the anatomical features in the root canal system were accessed. Because a long period is required to determine the clinical outcome, patient compliance must be encouraged. Copyright 2010. Published by Elsevier Inc.

  4. Distribution, den characteristics and diet of the Indian Fox Vulpes bengalensis (Mammalia: Canidae in Karnataka, India: preliminary observations

    Directory of Open Access Journals (Sweden)

    H.N. Kumara

    2012-11-01

    Full Text Available The Indian Fox Vulpes bengalensis inhabits relatively dry areas with scrub thorn forests, deciduous forests, short grasslands and marginal croplands. Since it is a widely distributed species, especially in the dry tracts, very little attention has been paid to it by researchers and wildlife managers. We conducted an extensive survey in the south Indian state of Karnataka to determine the conservation status of the Indian Fox. We also carried out a more detailed observation in a small region called “Jayamangali Blackbuck Block” (JBB and surrounding private lands to study the den site characteristics of the species. Except for a few districts in the Western Ghats and the west coastal region, the fox was present throughout Karnataka. Relatively higher encounter rates were observed in regions with extensive grasslands. We located 52 dens during the study in JBB which provide a minimum of 12dens/km2 with 1.33/km2 active dens. Circumference of den sites were smaller in JBB than in the adjoining private lands indicating that foxes frequently shifted dens in this area. The number of openings and active openings increased as the circumference of the den site increased. Fecal analysis revealed remains of certain species of plants, vertebrates and invertebrates, with arthropods as the major food items of the fox.

  5. Noise and vibration levels in artificial polar bear dens as related to selected petroleum exploration and developmental activities

    Blix, A.S.; Lentfer, J.W.

    1992-01-01

    Petroleum exploration and development are occurring in various locations in the Arctic, where there are important denning sites for polar bears. Petroleum activities usually coincide with winter denning activities by bears, who may abandon dens if subject to prolonged annoyance. A study was carried out to measure noise and vibration levels in artificial polar bear dens at Prudhoe's Bar, Alaska, resulting from seismic testing, drilling and transport. A microphone and an accelerometer were frozen to the floor of the dens, with leads passed through a consolidated snow filled entrance to a truck, tent or helicopter. Tests were carried out on land, sea ice, and next to a drilling tower on an artificial island, which was also used to measure noise levels resulting from a helicopter taking off. It was concluded that the dry and wind-beaten arctic snow muffles both sound and vibration extremely well, and it is unlikely that polar bears in their dens will be disturbed by the type of petroleum-related activities measured, provided they do not take place within 100 m of the dens. 8 refs., 7 figs., 1 tab

    Full Text Available Conventional forms of African American activism and organization in the second half of the twentieth century have been the subject of academic research for quite some time, but less attention has been devoted to symbolic and body political forms of intervention. Looking at the Afro hairstyle and hip hop culture, this article explores how African American identity has been reflected through Style Politics. It outlines the history of African American hairstyles from the 1970s until the 2000s and identifies elements of popular culture such as Blaxploitation movies and rap music as constitutive of African American fashion. The question of ›respectability‹ that surfaced in the context of racist discourses about black women will be examined through the example of First Lady Michelle Obama, who rose to fame as a fashion icon. In conclusion, the article discusses the case of Trayvon Martin, an African American teenager who was killed in 2012 while wearing a hoodie, making the garment once again an object of contention and a symbol of protest. * * * Klassische Formen des Aktivismus und der Organisierung von African Americans in der zweiten Hälfte des 20.

Skizziert wird die Geschichte afroamerikanischer Hairstyles von den 1970er- bis zu den 2000er-Jahren. Weiterhin werden Elemente der Populärkultur wie das Blaxploitation-Kino oder die seit den 1980er-Jahren verbreitete Rap-Musik als stilbildend für afroamerikanische Modephänomene identifiziert.

  8. Importance of native grassland habitat for den-site selection of Indian foxes in a fragmented landscape.

    Directory of Open Access Journals (Sweden)

    Girish Arjun Punjabi

    Full Text Available Fragmentation of native habitats is now a ubiquitous phenomenon affecting wildlife at various scales. We examined selection of den-sites (n = 26 by Indian foxes (Vulpes bengalensis in a highly modified short-grassland landscape in central India (Jan-May, 2010. At the scale of the home-range, defined by an 800 m circular buffer around den sites, we examined the effect of land-cover edges and roads on selection of sites for denning using a distance-based approach. At the smaller den-area scale, defined by a 25 m x 25 m plot around den and paired available sites, the effect of microhabitat characteristics was examined using discrete-choice models. Indian foxes selected den-sites closer to native grasslands (t = -9.57, P < 0.001 and roads (t = -2.04, P = 0.05 than random at the home-range scale. At the smaller scale, abundance of rodents and higher visibility increased the odds of selection of a site by eight and four times respectively, indicating resource availability and predator avoidance to be important considerations for foxes. Indian foxes largely chose to den in human-made structures, indicated by the proportion of dens found in earthen bunds (0.69 and boulder piles (0.27 in the study area. With agricultural expansion and human modification threatening native short-grassland habitats, their conservation and effective management in human-dominated landscapes will benefit the Indian fox. The presence of some human-made structures within native grasslands would also be beneficial for this den-dependent species. We suggest future studies examine the impact of fragmentation and connectivity of grasslands on survival and reproductive success of the Indian fox.

  9. Collar temperature sensor data reveal long-term patterns in southern Beaufort Sea polar bear den distribution on pack ice and land

    In response to a changing climate, many species alter habitat use. Polar bears Ursus maritimus in the southern Beaufort Sea have increasingly used land for maternal denning. To aid in detecting denning behavior, we developed an objective method to identify polar bear denning events using temperature sensor data collected by satellite-linked transmitters deployed on adult females between 1985 and 2013. We then applied this method to determine whether southern Beaufort Sea polar bears have continued to increase land denning with recent sea-ice loss and examined whether sea-ice conditions affect the distribution of dens between pack-ice and coastal substrates. Because land use in summer and autumn has also increased, we examined potential associations between summering substrate and denning substrate. Statistical process control methods applied to temperature-sensor data identified denning events with 94.5% accuracy in comparison to direct observations (n = 73) and 95.7% accuracy relative to subjective classifications based on temperature, location, and activity sensor data (n = 116). We found an increase in land-based denning during the study period. The frequency of land denning was directly related to the distance that sea ice retreated from the coast. Among females that denned, all 14 that summered on land subsequently denned there, whereas 29% of the 69 bears summering on ice denned on land. These results suggest that denning on land may continue to increase with further loss of sea ice. While the effects that den substrate have on nutrition, energetics, and reproduction are unclear, more polar bears denning onshore will likely increase human-bear interactions.

    Egypt occupies a progressed rank among the developing countries in prevalence of hepatic diseases and liver disorders. Hepatopathies are major public health problems in Egypt where hepatitis C virus (HCV) and schistosomia record a high prevalence which may account for the most serious clinical disorders e.g. liver cirrhosis and liver cancer.Vascular endothelial growth factor (VEGF) is the most specific and potent mitogen of endothelial cells. Hepatocellular carcinoma (HCC) is characterized by increased pathologic angio genesis and increased level of the vascular endothelial growth factor. Taurine is clinically used as a protecting agent of the liver and recently, its chemo preventive effect on rat large bowel carcinogenesis was reported.In this study, forty male albino rats were used and diethyl nitrosamine (DEN) was used for inducing pathological changes in different organs while taurine was given to investigate the possible protective effects on liver tissue after DEN treatment.The results showed elevation in serum AST, ALT, ALP, urea, creatinine, cholesterol and triglycerides in DEN group. On the other hand, estimation of sex hormones exhibited marked decrease in testosterone and significant increase in estradiol levels in DEN group as compared to control and taurine groups.Pathological examination of rat liver showed that DEN induced peri portal inflammatory cellular infiltrate, piece meal necrosis and necro inflammatory activity as well as the appearance of areas of haemorrhage and ballooning in hepatocytes. Moreover, moderate to high expression of V EGF in the cytoplasm of hepatocytes and sinusoidal cells were clearly observed while in control and taurine groups, normal architecture of hepatic tissue of rats was found and normal distribution of V EGF as diffuse or focal granular cytoplasmic stain in rats liver were observed. The prophylactic group showed minimal and mild changes in the liver tissue with absence of necro inflammation and the V EGF expression

    Nuclear chemistry and radiochemistry are very young sciences which developed at an extremely brisk pace within a very short period of time after the discovery of nuclear fission in 1938, and caused profound societal changes. In the United States, nuclear chemistry developed very differently from Germany, where nuclear research initially had been banned after the Second World War. The prime mover in the development in the United States was the Manhattan Project, the construction of the atomic bomb. The counteract the impending shortage of qualified personnel, important institutions have begun to establish training and support programs in the field. The National Laboratories in the United States introduced a National Security Internship Program, while the U.S. Department of Energy (DOE) tries to promote cooperation, and thus the training of personnel, by launching programs of its own. Yet, a greater shortage of qualified personnel is becoming apparent. The situation of nuclear chemistry and radiochemistry in the United States can be summarized in the finding that research at the National Laboratories is very wide ranging. It receives sufficient funds from the DOE. However, the National Laboratories show a very high proportion of elderly personnel, a problem which will have to be corrected in the years to come. This may be helped by the Summer Schools financed by the DOE, though a summer school of six weeks cannot replace a sound training in nuclear chemistry of the kind still to be found in Germany. (orig.) [German] Kern- und Radiochemie sind sehr junge Wissenschaften, die sich nach der Entdeckung der Kernspaltung 1938 innerhalb kuerzester Zeit extrem rasant entwickelt und tiefe gesellschaftliche Veraenderungen bewirkt haben. In den USA hat sich die Kernchemie sehr unterschiedlich im Vergleich zu Deutschland entwickelt, wo die Kernforschung nach dem 2. Weltkrieg vorerst verboten war. Massgeblich in den USA war dabei das Manhatten-Projekt zum Bau von Nuklearwaffen

  12. The use of cone beam computed tomography in the conservative management of dens invaginatus: a case report.

    2010-08-01

    To report the use of cone beam computed tomography (CBCT) in the assessment of dens invaginatus. Chronic periradicular periodontitis associated with an infected invagination was diagnosed in an immature mandibular lateral incisor tooth. A CBCT scan revealed essential information for the management of the tooth. There was no communication between the invagination and the main root canal. Endodontic treatment was carried out on the invagination. The root canal with a vital pulp was left untreated, thus allowing the tooth to mature and continue to develop. * The true nature of dens invaginatus cannot always be estimated from conventional radiographs. * Cone beam computed tomography is a useful diagnostic tool in the management of dens invaginatus.

    Full Text Available Artikkelen tar utgangspunkt i observasjoner fra et klasserom på ungdomstrinnet der elevene arbeider tverrfaglig i norsk, KRL og samfunnsfag. Temaet er blant annet jødenes situasjon før og under krigen. Læreren er faglig dyktig, erfaren og sterkt engasjert i å formidle overgrepene som ble begått mot jødene, og elevene er velvillige. Likevel er elevenes konklusjon at de i en krigssituasjon med en etisk fordring, ikke ville ha våget å gjøre noe for å hjelpe jødene.      Med utgangspunkt i diskursteori, sosiokulturell teori og nyere kognitiv teori diskuteres disse svarene som ”naturlige” svar i den konteksten som skapes i klasserommet, og gjennom det språket som elevene utfordres i, deres ”mediational means”. Et konkret didaktisk problem er at den historiske fortellingen er borte og erstattet av empatisk innlevelse. Artikkelen avslutter med å hevde at uten en narrativ ramme forsvinner muligheten for etisk erkjennelse gjennom konteksten som skapes, og gjennom materialet som foreligger. Her ligger imidlertid nye didaktiske muligheter for engasjerte lærere, ikke minst gjennom litteraturundervisning.

    2013-01-01

    Dens invaginatus is an anomaly characterized by an infolding of enamel and dentin that can lead to caries and pulpal death while the tooth is still immature, and present difficulties with diagnosis and treatment. Generally such open apices are managed by long term apexifaction procedures. This article demonstrated rapid management of a maxillary lateral incisor having a type 2 dens invaginatus, necrotic pulp, open apex and very large periradicular lesion using calcium hydroxide for one week prior to placement of a mineral trioxide aggregate (MTA) plug. After setting of the MTA, the remaining canal space was obturated using a warm vertical gutta percha technique. At 6 months follow-up the patient was asymptomatic, the lesion had almost entirely resolved, and, the root was already completely surrounded by bone. ©2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

    Dens invaginatus is a developmental abnormality that alters dental morphology; as a result, treating this condition is a challenge for endodontic practices. This article describes how a combination of nonsurgical and surgical therapies was utilized to treat a maxillary central incisor with Type III dens invaginatus and vital pulp. The treatment plan included using computed tomography (CT) for a detailed analysis of the dental anatomy and periapical area, endodontic and surgical procedures, and a 4-year follow-up period that included periodic clinical and radiographic examinations. The follow-up examinations revealed a regression of the apical lesion and no other signs or symptoms. Based on the present case report, the authors concluded that this combination of surgical and nonsurgical approaches was effective and that CT is a valuable auxiliary tool for the study of dental anatomy.

    2012-11-01

    Dens Invaginatus (DI) is a rare developmental anomaly which affects the tooth, which shows an infolding of enamel and dentine which extends into the pulp chamber and sometimes into the root. The aim of this case report was to describe its radiographic findings, to emphasize the bizarre morphology and the difficulties which are encountered in the diagnosis by using conventional radiographic techniques and the importance of computed tomography as a valuable diagnostic aid. Dens Invaginatus is clinically significant due to the possibility of an early pulpal involvement and the chronic periapical lesions are often associated with this anomaly without any clinical symptoms. Difficulties are encountered during the endodontic treatment, owing to the complex root canal anatomy; therefore, a proper radiologic evaluation by using different imaging modalities, is essential for its successful treatment.

    Dens invaginatus is a developmental anomaly resulting in an infolding of the enamel organ into the dental papilla prior to calcification of the dental tissues. The invagination predisposes the tooth for the development of dental caries. Conventional radiographs do not provide detailed information concerning the three-dimensional image, which would help the clinician in making a confirmatory diagnosis and planning the treatment before undertaking the actual treatment. This report describes a case where Oehlers type II dens invaginatus was diagnosed with the help of spiral computed tomography. The locations of the primary root canal and the invagination were assessed from spiral computed tomography scan images. Usually, the invagination is present on palatal/lingual side. However, in this case, the invagination was unusually located on labial side, which has yet not been reported. The tooth also showed certain unusual morphological features.

    Herzkrankheiten verursachen allein in den Vereinigten Staaten jährlich mehr als 700’000 Todesfälle. Ungefähr 3 Millionen Patienten in den U.S.A. leiden gemäss der American Heart Association (AHA) und dem National Heart, Lung and Blood Institute (NHLBI) an kongestivem Herzversagen (Congestive Heart Failure, CHF), welches eine chronische, sehr entkräftende und degenerative Krankheit ist: Das Herz ist dabei unfähig, hinreichend Blut zu den Organen des Körpers zu pumpen. Über 400’000 Fälle von CHF werden jedes Jahr diagnostiziert. Ähnliche Zahlen werden für Europa und Japan zusammen geschätzt. Basierend auf Daten vom AHA und NHLBI beträgt die fünfjährige Überlebensrate für CHF-Patienten lediglich etwa 50% [1]. 70’000-120’000 dieser Patienten könnten von einer Herzverpflanzung profitieren. 1999 wurden in den USA aber nur 2185 Herztransplantationen durchgeführt während die Warteliste über 4000 Patienten beträgt [2]. Ein akuter Mangel an Spenderherzen und die enormen Kosten (250’000-400’000 USD pro Patient) sind die begrenzenden Faktoren für Herztransplantationen [3]. Dies bedeutet, dass eine riesige Anzahl von Patienten durch ein zuverlässiges und verschleissfreies, nichtthrombotisches, total implantierbares, künstliches Herz gerettet werden könnten.

    Dens invaginatus is a dental malformation that may give rise to several complications. Caries of the invagination can severely weaken the whole tooth, making it susceptible to fracture. Subgingival fractures are major complications threatening tooth survival and usually require periodontal/orthodontic/prosthetic treatment if long-term viability is to be ensured. This article describes a case of single-session restoration of a fractured invaginated tooth by means of endodontic treatment followed by fragment reattachment.

    Dengue is an acute, emerging, infectious disease transmitted by Aedes mosquitoes that has become a serious global public health problem. The DEN2-FJ10 and DEN2-FJ11 strains of the dengue 2 virus were originally isolated from the serum of a patient with dengue fever in Fujian Province, China, in 1999. Our data provide the first assessment of the vector competence of Aedes mosquitoes with respect to the DEN2-FJ10 and DEN2-FJ11 strains of the dengue virus. There were significant differences in the replication rates of these two viral strains in Aedes albopictus and Aedes aegypti (Pdengue 2 virus (P>0.05). In summary, our results indicate that Ae. albopictus and Ae. aegypti mosquitoes are moderately competent vectors of the DEN2-FJ10 and DEN2-FJ11 strains of the dengue virus and provide the first evidence of the effect of these two viral strains on the vector competence of mosquitoes in China.

    Der aktuelle Wissensstand der Kern- und Elementarteilchenphysik hat eine wechselvolle Entstehungsgeschichte, oft gekennzeichnet durch schockierend neue Begriffsbildungen, die sich bis heute auch den Physik-Studierenden nur unter Mühen erschließen. Dieses Buch nutzt die kontroversen und zugleich lehrreichen Entwicklungsprozesse selber für den Zugang zu den schwierigen neuen Konzepten. Es macht verständlich, wie das physikalische Bild von den kleinsten Teilchen heute aussieht und warum es so und nicht anders entstanden ist: vom Nachweis der Existenz der Atome bis zum derzeitigen Standard-Modell der Elementarteilchenphysik, in einem ständigen Wechselspiel zwischen etablierten theoretischen Modellen, bestätigenden oder widersprechenden experimentellen Befunden, zuweilen umstrittenen neuen Begriffsbildungen, verbesserten Experimenten usw. - ein Prozess, der sicher auch künftig weiter geht. Leitschnur der Darstellung ist eine auch im Detail möglichst nachvollziehbare Argumentation. Physik-Studierende vor...

  5. The utopian challenge to global capitalism by Walter van den Broeck in Terug naar Walden

    Full Text Available The socialist sympathies that inform the writing of Flemish author Walter van den Broeck align him with a well-established tradition of socially engaged writing in Flanders. In his novel Terug naar Walden (Back to Walden, published in 2009, he revisits the Walden project of the Dutch reformer and writer Frederik van Eeden (1860−1932. Van den Broeck suggests that a reconsideration of the socialist ideals that inspired Van Eeden to establish settlements in the Netherlands and the United States is warranted in the light of the economic crisis triggered by unchecked capitalist practices in 2008. In Terug naar Walden Ruler Marsh, the richest man in the world, unleashes a global financial crisis as a form of retaliation against the capitalist system that ruined his parents. Marsh returns to the Kempen in Flanders where his family originated. In a Heideggerean affirmation of the local as exemplified by the country road, Van den Broeck articulates his vision of the common, that theorists Michael Hardt and Antonio Negri in their Empire trilogy have attempted to salvage from communist thinking, with a utopian notion that a stronger connection with the land and the people within one’s immediate environment may provide a useful premise for the development of viable alternatives to capitalism.

    Dens invaginatus is one of the most common anomalies of tooth structure. It is caused by the invagination of the crown surface during odontogenesis that enters the pulp chamber of the affected tooth. Depending on the complexity of invagination, the tooth might present with pulp necrosis, open apex and a complicated root canal system. This case report presents an Oehlers' type 2 dens-invaginatus in a mandibular premolar with chronic apical abscess. In most cases, dens invaginatus is removed during treatment. However, in this case report, based on cone-beam computed tomography (CBCT) evaluation, non-surgical treatment and maintenance of the invaginated segment was chosen in order to prevent compromising the tooth structure and its susceptibility to future root fracture. This is a new treatment approach and has not been performed in previous reports. Calcium-enriched mixture (CEM) cement was used as an apical plug followed by gutta-percha in warm vertical compaction for root canal obturation. The case was followed up for 36 months after treatment. This report highlights the importance of selecting the appropriate treatment approach based on CBCT evaluation.

    Dens invaginatus is a rare developmental anomaly that occurs during odontogenesis, with a higher prevalence in the Caucasian race and no significant sex predilection; it can be bilateral. This anomaly occurs in approximately 1.26% of the teeth, and the maxillary lateral incisor is most often affected. This case report describes a female patient with dens invaginatus in the maxillary right conoid lateral incisor. The patient presented to Araçatuba School of Dentistry, Universidade Estadual Paulista, São Paulo, Brazil, in 1995 with an acute periapical abscess in the palatal region of the tooth in question. After access preparation, the pulp in the main root canal was found to be vital and not associated with the abscess; therefore, surgical drainage of the abscess and root canal treatment of the main canal were performed. Surgical complementation was also performed to eliminate the infectious focus, which involved retrograde endodontic treatment of the dens invaginatus being obturated with Sealapex (Sybron Dental Specialties, Glendora, CA) and Ultrafil (Coltène/Whaledent AG, Altstätten, Switzerland). Radiographic assessments were completed periodically to verify healing. After 18 years, the patient returned to Araçatuba School of Dentistry, presenting crown fracture of the tooth in question. Radiographic examination showed repair and favorable conditions for tooth maintenance, so a post and porcelain core were made. The treatment was successful, achieving adequate repair with 18 years of follow-up. Copyright © 2014 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

    To remain internationally competitive company managements in the German coal mining industry must effectively use market opportunities on foreign coal markets. It is shown below that there can be no uniform, globally successful marketing strategy for the international coal market. Instead different marketing strategies specific to the countries should be implemented for commitments in the individual coal-producing countries. Such marketing strategies should be based on situation analyses of the individual coal-producing countries, which should be supplemented by opportunity/risk analyses. The systematology introduced for this purpose in based on the model of the product life cycle. The description concentrates on the coalproducing sector. (orig.) [Deutsch] Prognosen renommierter Institutionen lassen erwarten, dass die Steinkohlenbranche weltweit in den naechsten Jahrzehnten noch Wachstumspotentiale besitzt. Durch Nutzung dieser Potentiale im Zug einer Internationalisierung kann die deutsche Steinkohlenbranche schrumpfende Inlandsproduktion ersetzen. Im vorliegenden Beitrag wird gezeigt, dass es hierfuer keinen Koenigsweg einer einheitlichen, global erfolgreichen Marketingstrategie fuer den Weltsteinkohlenmarkt geben kann. Statt dessen sind laenderspezifisch differenziert gestaltete Marketingstrategien fuer Engagements in den einzelnen Kohlelaendern umzusetzen. Solche Marketingstrategien sollten auf Situationsanalysen der einzelnen Kohlelaender beruhen, die durch Chancen-/Risikenanalysen zu ergaenzen sind. Die hierzu vorgestellte Systematik beruht auf dem Modell des Produktlebenszyklus. Im Mittelpunkt der Darstellung steht der steinkohlenproduzierende Bereich. Basis fuer internationale Engagements sind vorhandene Kernkompetenzen. Zur erfolgreichen Realisierung solcher Strategien scheint die Organisationsform der Netzwerk-Organisation zweckmaessig zu sein.

    Whether worldwide, on the European Continent, or at national level, natural gas is coming to the front everywhere. In Latin America or South-East Asia, the natural gas industry is booming. However, the regional constraints of natural gas should not be forgotten. ``et`` interviewed a representative of the BEB company about the prospects of the natural business at large and the primary energy source no. 2 in the German energy market, where natural gas ranks second after mineral oil. The topics reported refer to basic regulatory policy requirements in order to safeguard a smooth functioning of the gas market, as well as suitable environmental policy instruments and strategies for management re-orientation to cope with the expected changes in the competitive situation. (Orig.) [Deutsch] Ob weltweit, kontinentaleuropaeisch oder national betrachtet - das Erdgas ist dort wie hier auf dem Vormarsch. In Lateinamerika und Suedostasien kann man regelrecht von einem Erdgasboom sprechen. Allerdings sollte man die regionale Gebundenheit der Erdgasnutzung nicht aus den Augen verlieren. `et` sprach mit dem `Unternehmen Erdgas` BEB ueber die Perspektiven des - nach dem Mineraloel - Primaerenergietraegers Nr. 2 auf dem deutschen Markt. Neben der Auslotung von ordnungspolitischen Grunderfordernissen fuer einen funktionierenden Gasmarkt und geeigneten Instrumenten fuer den Umweltschutz geht es um die Strategien fuer eine unternehmerische Neuausrichtung fuer den verschaerften Wettbewerb.

    In Hadronproduktionsdaten der e+e− - Vernichtungsexperimente JADE und OPAL messen wir die ersten f¨unf Momente von zw¨olf hadronischen Ereignisformvariablen bei Schwerpunktsenergien von 14 bis 207GeV. Aus dem Vergleich der QCD NLO-Vorhersage mit den mittels MC-Modellen um Hadronisierung korrigierten Daten erhalten wir den Referenzwert der starken Kopplung αs(MZ0) = 0.1254 ± 0.0007(stat.) ± 0.0010(exp.)+0.0009 −0.0023(had.)+0.0069 −0.0053(theo.) . F¨ur einige, insbesondere h¨ohere, Momente sind systematische Unzul¨anglichkeiten in der QCD NLO-Vorhersage erkenntlich. Simultane Fits an zwei Momente unter Annahme identischer Renormierungsskalen ergeben Skalenwerte von xμ=0.057 bis xμ=0.196 . Wir pr¨ufen Vorhersagen verschiedener nichtperturbativer Modelle. Aus der Single Dressed Gluon - N¨aherung ergibt sich eine perturbative Vorhersage in O(α5 s ) mit zu vernachl¨assigender Energiepotenzkorrektur, die den Mittelwert von Thrust auf Hadronniveau gut beschreibt mit αs(MZ0) = 0.1186 ± 0.0007(st...

    An accurate understanding of the morphology of the root canal system is a prerequisite for successful root canal treatment. Invaginated teeth have a complex root canal configuration that cannot be instrumented effectively. Correct diagnosis and treatment planning are fundamental to treatment of dens invaginatus. Periapical surgery is indicated in cases where a nonsurgical approach fails. A case of dens invaginatus type 3 in a maxillary lateral incisor with a periapical lesion and its successful treatment by these combined methods is reported. PMID:25206122

    Present study, was an effort to scrutinize the molecular and biochemical role of ibuprofen and thiamine combination in diethylnitrosamine (DEN)-induced HCC in Wistar rats. Single intraperitoneal injection of DEN (200 mg/kg) was used for induction of HCC in rats. The rats were divided into eight various groups. DEN induced rats were treated with pure ibuprofen (40 mg/kg) and thiamine in combination for the period of 12th weeks. The protocol was terminated after the 16th week. Exposure of DEN up-regulated the levels of different serum biochemical parameters, antioxidant enzyme level, Alfa-fetoprotein (AFP) and reduced the level of High density lipoprotein (HDL) in Wistar rats along with the alteration in pro-inflammatory cytokines viz., interlukin-6 (IL-6), Tumor necrosis factor (TNF-α) and Interleukin-1β (IL-1β) with decrease in body weight. Macroscopic evaluation, revealed DEN group rats confirmed the expansion of hepatic nodules, which were reduced by the individual treatment of ibuprofen and thiamine, but the synergistic treatment of ibuprofen and thiamine confirm the significant reduction of hepatic nodules. Further, this combination possesses the significant chemoprotective effect in DEN-induced HCC by restoring the hepatic enzymes and other biomarkers along with an alteration in pro-inflammatory cytokines. The above result concludes that ibuprofen and thiamine combination possess potent anti-cancerous activity. Copyright © 2017 Elsevier Inc. All rights reserved.

En viktig uppgift men också en stor utmaning för högskolans lärare är att stödja studenter i deras språkutveckling så att fler får möjlighet att fullfölja sin akademiska utbildning. Den här artikeln bygger på en kvalitativ undersökning av hur studenter vid ett tillfälle samtalar om en vetenskaplig artikel som ingår i deras utbildning. Vårt syfte är att diskutera vilka möjligheter innehållet i studenternas samtal ger för att utveckla deras förståelse av den vetenskapliga texten och dess kontext.

    Full Text Available Laut Nachrichtenwertforschung hängt die Publikations- und Lesenswürdigkeit von Nachrichtentexten von den Nachrichtenfaktoren der zu publizierenden Ereignisse ab. Als anerkannte Nachrichtenfaktoren gelten beispielsweise Negativität, Vereinfachung und Personifizierung. Friedensjournalistische Arbeiten weichen von diesen Kriterien oft ab, indem sie versuchen, die berichteten Ereignisse in ihrer Komplexität darzustellen, den Fokus nicht auf negative Ereignisse zu legen und auch strukturellen Themen Raum zu geben. Aber sind sie deshalb weniger publikationswürdig? Der folgende Artikel zeigt anhand einer experimentellen Studie, welche Akzeptanz Friedensjournalismus beim Leser finden kann, auch wenn dies teilweise den Theorien der Nachrichtenwertforschung widerspricht. Des weiteren wird gezeigt, wie sich konstruktive Berichterstattung auf die mentalen Modelle der Rezipienten auswirkt und in welchem Zusammenhang diese beiden Ergebnisse miteinander stehen. In der vorliegenden Studie wurden einer für die Leserschaft der deutschen Qualitätspresse hinsichtlich Alter und Bildungsgrad repräsentativen Stichprobe von n = 128 Versuchspersonen Zeitungsartikel zu drei verschiedenen Ereignissen im Konfliktfeld des ehemaligen Jugoslawien dargeboten.

    2015-01-01

    Full Text Available Dens Invaginatus (DI is a rare developmental malformation of teeth, resulting from an infolding of dental papilla. The increased risk of pulpal pathologies associated with DI makes it clinical relevant. Only few cases have been reported where double DI was found associated with supernumerary teeth. Diagnosis of DI with the conventional radiographs is not easy, so advanced imaging modalities are must. This paper highlights a rare case of bilateral double DI in multituberculated maxillary central incisors with impacted supernumerary teeth with its clinical and imaging features.

    This study was designed to find out the efficacy of ethanol extracts of Punica granatum peel and Vitis vinifera seeds on diethylnitrosamine (DEN)-induced oxidative stress and hepatocellular damage in Wistar rats. Rats were divided into four groups. The first group served as normal control, and the second group received DEN at a dose of 200 mg/kg body weight by single intraperitoneal administration. The third one received DEN as in DEN-treated group and co-treated with 400 mg/kg P. granatum peel extract. The final group also received DEN and co-treated with 400 mg/kg V. vinifera seed extract. DEN administration to rats resulted in significantly elevated levels of serum SGPT, SGOT, ALP, and GGT which is indicative of hepatocellular damage. DEN-induced oxidative stress was confirmed by elevated levels of lipid peroxides and decreased activities of superoxide dismutase, catalase, and glutathione peroxidase in the serum and liver tissues. The status of non-enzymatic antioxidants like vitamin C, vitamin E, and reduced glutathione were also found to be decreased in serum and tissues of DEN-administered rats. Co-treatment with the P. granatum peel and V. vinifera seed extracts orally for 12 weeks significantly reversed the DEN-induced alterations in the serum and liver tissues.

    Deutsche Bahn is presently endeavouring to further improve the interaction between the overhead wire and the current collectors on its locomotives and trainsets. The major factors behind this initiative are cost, quality and noise prevention. The outcome is the development of a completely new type of current collector for high-speed operation even on conventional track. Prototypes have meanwhile undergone practical trials on the 200 km/h line from Augsburg to Donauwoerth. The new current collector is a single-arm pantograph jointly developed by DB and Bombardier Transportation. (orig.)

  4. Ethik und Politik im Anschluss an Levinas – Zwischen dem einen und den vielen Anderen?

    2016-07-01

    Full Text Available Wird in philosophischen Diskussionen auf Emmanuel Levinas Bezug genommen, bleibt es zumindest in einigen Theoriekontexten häufig bei dem Verweis auf den „Anderen“, dem wir die Moral schulden, gelten doch seine Schriften immer noch als metaphysisch aufgeladen und in ihrer Radikalität als unplausibel. Weitgehend außer Acht gelassen wird dabei, wie Levinas sich dazu äußert, dass wir in der Welt nie nur mit einem, sondern mit vielen Anderen leben und somit vor der Frage stehen, wie wir diesen allen gerecht werden können. Auch dass für Levinas diese Frage nicht mehr in den Bereich der Ethik, sondern in das Feld der Politik gehört, wird entsprechend oft nicht weiter reflektiert. Um das Verhältnis zwischen Ethik und Politik bei Levinas im Hinblick auf einen Dialog mit anderen Theorieansätzen näher zu beleuchten, werde ich zunächst wichtige Grundannahmen seiner Philosophie in Erinnerung rufen. In einem zweiten Schritt werde ich überlegen, inwiefern die Bezugnahme auf seine Arbeiten für andere moralphilosophische Ansätze fruchtbar sein könnte. Schließlich werde ich darlegen, inwiefern auch für an Levinas anknüpfende Theorien eine Öffnung hin zu anderen Philosophietraditionen sinnvoll ist.

    Dens Invaginatus (DI) is a rare malformation of the teeth, showing a broad spectrum of morphologic variations. The aim of this study was to perform in vitro radiographic analyses of three extracted dens invaginatus (DI) teeth with complex root anatomy using plain radiographs, CBCT, MRI and micro CT techniques. Study design: Three maxillary lateral incisors (A, B and C) from two patients were extracted due to poor prognosis and were radiographically analysed. Initially, conventional two dimensional digital radiographs were taken. Subsequently CBCT, micro CT and MRI analyses were performed. According to the Schulze and Brand system of classification, teeth A, B and C were classified as A2, B3 and B2 respectively. To detect the relationship between the invagination to the oral cavity and pulp chamber, conventional two dimensional radiographs were of no help. CBCT and MRI images were found to be complementary to each other but provided lesser structural detail than micro CT images. Reporting on these three DI teeth, normal conventional radiographs did not provide detailed structural information about the malformation due to geometric distortion and lack of information. Even though Oehlers classification system is the most widely used, classification by Schulze and Brand is more applicable in rare and deviant teeth.

  6. Use of computed tomography in diagnosis and management of type III dens invaginatus

    2009-01-01

    Full Text Available Background: Dens invaginatus is a developmental malformation, which concerns the non-typical arrangement of dental hard tissues. Conventional diagnostic aids like radiographs play an important role in assessment of complex root canal morphologies. These modalities, however, do not provide detailed information of the complexity as a result of their inherent limitations. This calls for use of more advanced imaging modalities such as computed tomography, which can help the clinician in making a more accurate diagnosis. Report: Type III Dens invaginatus was detected in a 20 year old male patient corresponding to the maxillary lateral incisor and showing extensive periradicular radiolucency and a vestibular sinus. The radiographic and tomographic examination revealed 2 apices: one wide open in the distal part of the root and the other normally formed in the mesial. Treatment plan: Combined non-surgical and surgical endodontic therapy with MTA as a retrograde filling material was planned in this case. Outcome: At follow-up examination after 6 months, the tooth was asymptomatic and radiographically showed repair of the lesion.

    Dens invaginatus is a well-known malformation of teeth, which probably results from an invagination of enamel organ into dental papilla during tooth development. The endodontic treatment of invaginated teeth may be challenging due to difficulties in accessing the root canals and also due to complex variations of internal morphology. This article presents the endodontic management and follow-up in a rare case of right mandibular second premolar with Oehlers' type III dens invaginatus. The result of cold pulp testing was positive for this tooth but it was associated to a sinus tract and periapical lesion. Herein, it is described the root canal therapy of this tooth combined with periapical surgery, emphasizing the importance of proper diagnosis and planning by using cone beam computed tomography (CBCT). This case report presents the proper periapical healing 6 months after the combination of nonsurgical and surgical treatments. It also shows that CBCT is an important auxiliary examination to avoid errors in diagnosis and subsequent treatment of dental anomalies.

    Full Text Available Dens Invaginatus is a dental malformation that poses diagnostic difficulties in the clinical context. This anomaly may increase the risk of pulp disease and can potentially complicate endodontic procedure due to the aberrant root canal anatomy. Compared to conventional radiographs, three-dimensional images obtained with Cone Beam Computed Tomography (CBCT are invaluable in the diagnosis of the extent of this anomaly and in the appropriate treatment planning. Oehler’s classification (1957 for Dens Invaginatus (DI into three types depending on the depth of the invagination has been used for treatment planning. Of the three types Type III DI is characterized by infolding of the enamel into the tooth up to the root apex and is considered as the most severe variant of DI and hence the most challenging to treat endodontically, due to the morphological complexities. This report describes a case of Oehler’s Type III DI in a necrotic permanent maxillary lateral incisor in which CBCT images played a key role in diagnosis and treatment planning. The case was managed successfully by a combination of nonsurgical and surgical endodontic therapy with orthograde and retrograde thermoplastic gutta percha obturation.

    Hibernating brown bears (Ursus arctos) and black bears (Ursus americanus) spend half of the year in a physically inactive state inside their winter dens without food intake and defecating and no or little urination. Under similar extreme conditions, humans would suffer from loss of lean body mass, heart failure, thrombosis, azotemia, osteoporosis, and more. However, bears exit the den in the spring strong without organ injuries. Translational animal models are used in human medicine but traditional experimental animals have several shortcomings; thus, we believe that it is time to systematically explore new models. In this review paper, we describe physiological adaptations of hibernating bears and how similar adaptations in humans could theoretically alleviate medical conditions. The bear has solved most of the health challenges faced by humans, including heart and kidney disease, atherosclerosis and thrombosis, and muscle wasting and osteoporosis. Understanding and applying this library of information could lead to a number of major discoveries that could have implications for the understanding and treatment of human disease. © 2015 Wiley Periodicals, Inc.

    1985-08-01

    Within the last decade unusually high frequencies of neoplasms have been reported in feral fish populations from a variety of locations. At many of these locations organic carcinogens have been noted as a potential cause. The authors sought to identify toxic effects including neoplasia in fish exposed to an organic carcinogen, and to quantify these effects through time. They exposed guppies (Poecilia reticulata) to multiple doses of DEN, an organic carcinogen. Fish were then subsampled and examined for liver histopathology at 2-month intervals over 12 months. Necrotic zones, macrophage centers, bile duct proliferations, enlarged lipid deposits, neoplastic foci, cholangiocarcinomas and hepatoblastomas were quantified by frequency of occurrence and the percentage of liver area involved. DEN toxicity resulted in necrotic zones that peaked in frequency at the first sample period (2 months). Lipid deposits increased, then plateaued in guppies, indicating a more chronic toxic effect. Similarly, macrophage centers increased through the sampling period. Bile duct proliferation appeared to be of two types: a reversible toxic response which peaked at 4 months and then declined and a less frequent irreversible proliferation which continued to develop into cholangiocarcinoma. The irreversible bile duct proliferations and the neoplastic foci had cellular densities different from corresponding control tissue and similar to cellular densities of cholangiocarcinomas and hepatoblastomas, respectively.

    Young-Jun Lim

    2012-02-01

    Full Text Available Cone-beam computed tomography (CBCT is a useful diagnostic tool for identification of both internal and external root configurations. This case report describes the endodontic management of a lateral incisor with both dens invaginatus and external root irregularity by using CBCT. Nonsurgical endodontic retreatment was performed on the lateral incisor with dens invaginatus. A perforation through the dens invaginatus and external concavity was repaired using mineral trioxide aggregate. After 18 mon of follow-up, there were no clinical symptoms. Recall radiographs appeared normal and showed healing of the periapical pathosis. The understanding of both internal root canal configuration and external root irregularity using CBCT can ensure predictable and successful results.

    2014-01-01

    Talon cusp and dens invaginatus are developmental anomalies of the human dentition. They not only affect the esthetic appearance of teeth but also may create difficulties during dental treatment and lead to a number of dental problems. Both anomalies are observed most commonly in the lateral maxillary incisor and rarely in the mandibular dentition. The simultaneous occurrence of talon cusp and dens invaginatus in a single tooth is very rare in the mandibular dentition and, to the authors' knowledge, has not yet been reported in a mandibular lateral incisor. This article presents a rare case of dens invaginatus and talon cusp occurring concurrently in a mandibular lateral incisor. Three-dimensional imaging modality was used to describe the complex internal anatomy.

    Congenital morphological dental alterations are related to the physiological phase of tooth development. Since the etiology of the dens invaginatus and supernumerary roots has yet to be fully determined, a rare presentation of dens invaginatus in a primary molar and a birooted deciduous maxillary canine were incidentally detected in routine radiographic examinations. Essential clinical considerations and treatment options are presented. This study highlights the importance of a deep and comprehensive anamnesis and clinical examination, with radiographs taken when necessary. The negligence of these stages in an initial consultation could cause irreversible future damage to the patient, since rare dental anomalies or other lesions that require treatment may not be detected.

    Häufig kommt in Software Projekten früher oder später die Frage auf, wie man unabhängiger von einer Datenbank eines Herstellers wird. In den seltensten Fällen ist es gewünscht oder notwenig auf die Datenbank eines Herstellers zu setzen. Eine Applikation unabhängig von einer Datenbank zu gestalten, bietet einige Fallstricke. Der Catacomb WebDAV Server ist bei seiner Entstehung auf eine spezische Datenbank hin entwickelt worden. Ziel dieser Diplomarbeit ist den Catacomb WebDAV Server Datenba...
