RESUMO Introdução: o tratamento de dentes jovens traumatiza-dos requer atenção especial, devido à possível presença de ápice incompleto e paredes dentinárias delgadas, o que pode dificultar ou comprometer o tratamento endodôntico convencional. Faz-se necessária a realização de um proce-dimento para induzir a formação de uma barreira minera-lizada, com o auxílio de materiais biocompatíveis, como o hidróxido de cálcio e o agregado trióxido mineral (MTA). Objetivo: relatar um caso clínico em que foi realizada apicificação, com tampão de MTA, em um incisivo lateral superior traumatizado. Conclusão: o uso de MTA como material obturador de dentes com ápice incompleto mos-trou-se eficiente, pois permitiu resolução do caso com su-cesso e a manutenção do dente na arcada, exercendo suas funções primárias quanto à estética e à mastigação. Palavras-chave: Apicificação. Agregado trióxido mineral.

Root resorption is a dental complication especially involved in endodontic treatment, which represents a clinical challenge. The failure could lead to dental loss. Factors of resorption could be dental trauma, surgical procedures, excessive pressure or irritation from bleaching agents.[1] Internal root resorption has not been proven to be hereditary or to be contagious. The process is slow to advance and therefore many cases are not detected until the painful response from the patients. As mineral trioxide aggregate (MTA) has been indicated for the treatment because of its sealing ability, biocompatibility and potential induction of osteogenesis and cementogenesis.2 The following case reviews represent the diagnosis, treatment methods and the results of the use of MTA in internal root resorption.

Mustafa Kemal Atatürk’ün direktifleri doğrultusunda Cumhuriyet hükümeti, ülkenin ihtiyacı olan kadroları yetiştirmek amacıyla yurtdışına eğitim amaçlı olarak çok sayıda burslu öğrenci göndermiştir. Burslu öğrenci gönderen devlet kurumları arasında Maden Tetkik ve Arama Enstitüsü (MTA) de vardır. Amaç, Türkiye’nin işletmeye elverişli maden rezervlerini belirlemek ve bu alanda araştırma yapacak, eğitim verecek teknik eleman ve mühendislerini yetiştirmektir. Gönderilen burslular arasında Sadrettin Alpan da vardır. 1944 yılında İngiltere’ye giden Alpan, Birmingham Üniversitesi’nde maden mühendisliği öğrenimi görmüştür. Aynı üniversitede “Taş Matkabı” konulu teziyle doktorasını tamamlayan Alpan 1951’de Türkiye’ye dönerek MTA’da göreve başlamış, 1960 yılında MTA Genel Direktörlüğü’ne getirilmiştir. Atom Enerjisi Komisyonu’nda ve Birleşmiş Milletler’de uzun yıllar görev yapmış olan Alpan 1954 yılında İTÜ’den doçent ünvanı almış, Türkiye’nin belli başlı üniversitelerinde dersler vermiştir. Tanıtılan bu kitap Sadrettin Alpan ile yapılan sözlü tarih çalışması sonucunda hazırlanmıştır.

Les Néandertaliens ont occupé la totalité du territoire belge, ce qui se traduit aujourd’hui par 441 points de découvertes d’éléments lithiques. Les instruments bifaciaux y abondent, puisque 184 de ces sites en ont livré, et permettent d’identifier diverses influences régionales. Le bref aperçu que nous en avons donné illustre toute la complexité liée à cette documentation. Des pièces bifaciales typiquement rapportables tantôt au M.T.A., tantôt au K.M.G. sont représentées, ainsi que des « modèles intermédiaires ». La position du territoire belge n’est pas étrangère à cette situation. Situé à la marge septentrionale des régions à forte tradition M.T.A. et à la marge occidentale du K.M.G., il constitue—au même titre que l’est et le nord de la France — une zone tampon où influences occidentales et orientales se mêlent et s’entremêlent jusqu’à constituer des industries atypiques.

In this paper we present two interactive multi-user systems for video search and browsing. The first is composed by web applications which allows multiuser interaction in a distributed environment; such applications are based on the Rich Internet Application paradigm, designed to obtain the levels of responsiveness and interactivity typical of a desktop application. The second system implements a multi-user collaborative application within a single location, exploiting multi-touch devices. Both systems use the same backend, based on a service oriented architecture (SOA) that provides services for automatic and manual annotation, and an ontology-based video search and browsing engine. Ontology-based browsing let users to inspect the content of video collections; user queries are expanded through ontology reasoning. User-centered field trials of the systems, conducted to assess the user experience and satisfaction, have shown that the approach followed to design these interfaces is extremely appreciated by professional archivists and people working on multimedia.

Metastasis-associated protein 1 (MTA1) and its short form (MTA1s) regulate the function of estrogen receptors (ERs). Estrogens, via ERs, affect placental growth and fetal development, a process that may involve MTA1 signaling. Expression of MTA1, MTA1s, ERa, and ERb genes and proteins in rat placentas was studied on 16, 19, and 21 days of gestation (dg). The ERb messenger RNA decreased significantly toward the end of gestation, whereas its protein level increased in the nuclear fraction on 21 dg. Both MTA1 and MTA1s increased with gestation. Decidual, trophoblast giant, glycogen, and villous trophoblast cells expressed MTA1, ERa, and ERb proteins on all dg with colocalization of MTA1 with ERa and ERb in the nucleus and cytoplasm. Expression of MTA1 suggests a possible role in regulating placental functions; considering the repressive function of MTA1 on ERs, the expression of MTA1 suggests that placental cells may be less sensitive to estrogens during late pregnancy.

The aim of this study was to evaluate the response of rat subcutaneous tissue to MTA Fillapex® (Angelus), an experimental root canal filling material based on Portland cement and propylene glycol (PCPG), and a zinc oxide, eugenol and iodoform (ZOEI) paste. These materials were placed in polyethylene tubes and implanted into the dorsal connective tissue of Wistar rats for 7 and 15 days. The specimens were stained with hematoxylin and eosin, and evaluated regarding inflammatory reaction parameters by optical microscopy. The intensity of inflammatory response against the sealers was analyzed by two blinded and previously calibrated examiners for all experimental periods (kappa=0.96). The histological evaluation showed that all materials caused a moderate inflammatory reaction at 7 days, which subsided with time. A greater inflammatory reaction was observed at 7 days in the tubes filled with ZOEI paste. Tubes filled with MTA Fillapex presented some giant cells, macrophages and lymphocyt...

Root resorption is of major concern to endodontists. It is one of the common causes for root perforation which complicates endodontic treatment and often results in periodontal destruction.  Proper diagnosis and an understanding of the aetiology and dynamics of the processes involved in tooth resorption is critical for effective management. Tooth resorption can have a multifactorial etiology. Traumatic injury, orthodontic treatment, bacteria, bacterial products and tissue destruction products within the root canal, periodontal treatment, local pressure and inflammation are some of the common causes for tooth resorption. Multinucleated clastic cells are responsible for destruction of bone, dentin and cementum. Usually a multidisciplinary approach is required in managing such cases. The following case report represents a surgical management of a tooth with combined internal and external resorption. The initiation and progression of the resorptive lesion has occurred due to iatrogenic errors from the previous endodontic treatment that resulted in a large perforation defect on the facial aspect of the upper left canine tooth associated with severe pain and periodontal involvement.

Management of the teeth was done in three stages. The use mineral trioxide aggregate (MTA) has resulted in the repair of the resorptive defect.  Periodontal surgery with regenerative procedures were carried out in the later stage. At  two year followup, the tooth showed signs of healing and arrest of root resorption along with  considerable bone fill. Treatment of the mutilated teeth in three stages and involvement of an interdisplinary approach have resulted in good esthetic and functional outcome.

My paper considers public art that engages with the moving image.  Since most film theory assumes a static spectator and most writing on public art neglects temporality, works such as Bill Brand's Masstransiscope, a short abstract film installed as a large-scale zoetrope in an abandoned subway station in Brooklyn, exist somewhere in between.  This permanent work, one of the earliest completed with the help of Creative Time, also has a fraught history with deterioration and renovation.
