Tooth avulsion is a type of dental injury defined as the complete displacement of a tooth out of the alveolar socket, and the lack of prompt treatment measures can result in the loss of function, poor quality of life, and psychological and social problems. However, several factors may not permit the immediate replantation of an avulsed tooth; therefore, delayed replantation has emerged as an alternative to meet the esthetic, functional, and psychological demands of patients. Here it was described that the successful replantation of an avulsed maxillary central incisor in a 9-year-old boy who presented at the clinic with the tooth stored in unfavorable conditions as dry and then in olive oil-milk mixture almost 10 h after the event. The tooth has remained in its socket healthy for 16 years after treatment. The patient was satisfied with both esthetics and function.

Introduction The aim of the study was to evaluate the in vitro microleakage of new flowable compomers in the class V cavities of primary teeth. Methods Thirty freshly extracted, non-carious, primary molars without visible defects were used in this study. Class V cavities (n = 60), with the occlusal and cervical margins located in the enamel, were prepared on the buccal and lingual surfaces. The samples were randomly divided into 3 groups of 20 each. Group 1: restored with Twinky Star Flow (Voco, Cuxhaven, Germany), Group 2: restored with Dyract Flow (Dentsply, Konstanz, Germany) and Group 3: restored with R&D Series Nova Compomer Flow (Imicryl, Konya, Turkey) according to the manufacturer's instructions. After a thermocycling regimen of 1000 cycles between 5°C and 55°C, the samples were isolated, immersed in 0.5% basic fuchsine solution for 24 h at 37°C and sectioned longitudinally in a buccolingual direction. The sections were evaluated for values of microleakage with a stereomicroscope. Results All materials showed microleakage but no statistically significant difference was observed among the groups (p>0.05). The highest microleakage score was observed in group II (1.65 ± 0.49) and group I (1.75 ± 0.44) at occlusal and gingival margins, respectively. Conclusions Flowable compomers showed insignificantly least amount of microleakage in class V cavities prepared on primary molars.

Background: The aim of the present study was to determine Shear bond strength (SBS) of different flowable compomers on the enamel surface of primary teeth. The null hypothesis to be tested was that none of the flowable compomer would differ significantly from the other two with respect to SBS. As a result, the tested materials that have the easiest application on child patient is preferred. Material and Methods: Sixty newly extracted non carious primary molars were selected. The buccal surface was cleaned and polished to obtain a flat enamel surface. The specimens were randomly divided into three groups of 20 teeth each, based on the flowable compomers applied, as follows: group I: Dyract Flow® (Dentsply, Konstanz, Germany); group II: Twinky Star Flow® (Voco, Cuxhaven, Germany); and group III: R&D Series Nova Compomer Flow® (Imicryl, Konya, Turkey). Results: SBS in group II (6.78± 0.45 MPa) were significantly lower than groups I and III (8.30 ± 0.29 and 8.43 ± 0.66 MPa, respectively) ( P

Background: Fine-needle aspiration cytology (FNAC) in the diagnosis of thyroid nodules is an easy and cost-effective method. The increase in malignancy rates of the excised nodules due to the high sensitivity and specificity rates of the FNAC is remarkable. Aim: The aim of this study was to assess the effectiveness of FNAC in the evaluation of thyroid nodules by comparing the results with histopathologic evaluation and comparing the consistency of the results with the literature. Materials and Methods: In this study, 1607 FNACs of 1333 patients which were classified according to the Bethesda system and 126 histopathological evaluations obtained from this group were evaluated. The mean age of the patients was 51.24 (range: 17-89, 17% male and 83% female). The sensitivity, specificity, positive and negative predictive values, and accuracy rates were evaluated. Results: The sensitivity was 87.1% and specificity was 64.6%. The positive and negative predictive value and accuracy rates were 76.1%, 79.5%, and 77.3%, respectively. Conclusions: In our study, the evaluation of thyroid FNAC samples with Bethesda system highly correlated with the results of histopathological diagnosis. However, combination of additional and advanced diagnostic methods such as immunocytochemical studies and molecular pathology techniques enhance the prognostic value of FNAC in patients with atypia of undetermined significance or follicular lesion of undetermined significance, lesions suspicious for malignancy, and suspected follicular neoplasm.

Bu çalışma, öznelliklerimizi ortaya çıkaran, yani bakış açılarımızı sınırlandırarak millet, cemaat ve cemiyet gibi sosyolojik varlıkları ortaya çıkaran çerçeveleri sorgulamaktadır. İnsanın tüm duyularına sınırlama koyabilen, dünyayı ve nesneleri öyle değil de böyle algılamamızı sağlayan sınırlandırmalar hangi mekanizmalarla ve ne gibi araçlarla işlemekte, psişik düzeyde sonuçları nasıl ortaya çıkmaktadır? Daha da önemlisi, ?iç-dış? bölünmesi sonucunda öznelliğin meydana çıkmasını sağlayan araçlar nelerdir? Elinizdeki çalışma, Osmanlı öznelliğinin oluşumunu incelerken bu sorulara özgün cevaplar vermeyi amaçlamaktadır. Geçtiğimiz yüzyılda sosyal bilimler alanında yeni yöntemsel mecralar açan psikanalitik kuram, bu konuda oldukça verimli çalışmaların yapılmasını sağladı. Sigmund Freud'un insan ruhunun dinamiklerine dair fikirleri ve Jacques Lacan'ın özne kuramları, bu verimli mecraın niteliğini belirlemede önemli rol oynadı. Kimlik tartışmaları, aidiyet, mensubiyet ve cinsiyet konuları kadar milliyetçilik ve hatta ırkçılık ve zenofobi gibi hararetli sosyal fenomenleri ele alırken, psikanalizin açtığı yeni alanı zemin olarak kullanan oldukça geniş hacimli bir akademik külliyat meydana geldi. Metodolojik açıdan, elinizdeki çalışma, psikanalizin getirdiği imkânları kullanmayı denemektedir. Fransız psikanalist Jacques Lacan'ın iki kavramını, yani ?gerçek? ve ?imgesel? kavramlarını esas alarak, ?iç-dış? düalizminin farklı tarihsel bağlamlarda ne tür sınır araçlarıyla ortaya çıkarak Osmanlı öznelliğini meydana getirdiğini araştırmaktadır. İç-dış düalizmini yaratan araçları, genel olarak iki başlık altında incelemektedir: ?Gerçek eşikler? ve ?imgesel eşikler?. Gerçek eşikler, insan bedenini sınırlayan her türlü maddi engelden meydana gelir (dağlar, denizler, nehirler gibi doğal engellerin yanısıra, savaş mimarisinin ürettiği her türlü tasarlanmış engel bu başlığa dahil edilebilir). İmgesel eşikler ise, tıpkı aynadaki imajlarımız gibi, sosyal yaşamdan akisler halinde bize dönen her türlü ?benlik? imgesidir (diplomatik metinler ve mitolojiler gibi). Elinizdeki çalışma, Lacan'ın bu iki kavramını ödünç almakla birlikte, bu iki kavramı gerektiğinde eğip bükerek, çalışmanın sorularına yanıt ararken onları daha ?ergonomik? hale getirmekte, böylece bu kavramlara kısmen özgün anlamlar da yüklemektedir. This work examines the nature of frames that restrict our perspectives and thus give birth to such sociological entities like societies, communities and nations. How is the dualism of ?inside-outside? created on sociological and psychic levels? More importantly, what instruments play what kind of roles in the creation of that dualism? Examining the formation of Ottoman subjectivity as a case, this study gives original answers to these questions. The psychoanalytic theory, which opened a new methodological domain for the social sciences in the past century, productively accommodated a good amount of works on these questions. Sigmund Freud?s pioneering works on the dynamics of human psyche and Jacques Lacan?s theories of human subjectivity played important roles in the improvement of this domain. Beginning from the second half of the past century, discussions on identity and belonging, as well as such furious social questions as nationalism, racism and xenophobia, have been held in the light of the new approaches of psychoanalytic theories in the field of social sciences. In this sense, this study can be seen as a part of those approaches, because methodologically, it bases itself on the opportunities offered by a particular psychoanalytic theory, namely, that of a French psychoanalyst, Jacques Lacan. I pick up two of Lacan?s productively scrutinized concepts, namely the ?real? and the ?imaginary?, to develop a particular perspective towards this question: How is the dualism of inside-outside created in different contexts throughout the Ottoman history, so that this dualism could give birth to Ottoman subjectivity? Taking the two Lacanian concepts as a base, I analyze the instruments that play the role of ?thresholds? in the formation of the dualism of ?inside-outside?, under two general headings: The ?real thresholds? and the ?imaginary thresholds?. To put in a very brief manner, a ?real threshold? is born out of any material obstacle that puts restrictions of any kind to the abilities of human body (natural obstacles like mountains, rivers and oceans, as well as designed obstacles like any object of war architecture, for instance, fall into this heading). Imaginary thresholds, on the other hand, are the ?images of selves? that reflect back to us on the social ground, just in the same manner as our mirror-images come back to us and provide us with a subjective feeling of self (like the diplomatic texts and the mythologies). Although I borrow the two Lacanian terms (i.e. real and imaginary) to build up a theory of thresholds, I do not hesitate to bend and reshape those concepts whenever necessary, to build the conceptual tools into a rather ergonomic manner. 281
