Use of a Surgical Guide in a Crown-Lengthening Procedure to Improve the Aesthetics of the Interdental Papillae: A Case Report

Aim: This case report describes the use of a surgical guide in a crown-lengthening procedure to improve the aesthetics of the anterior interdental papillae in an adult female patient.&#x0D; Methodology: A 40-year-old female underwent a crown-lengthening procedure with guidance provided by a surgical template to correct unsatisfactory aesthetics in the anterior gingiva and prosthesis.&#x0D; Results: The patient’s functional and aesthetic expectations were met successfully with interdisciplinary treatment, including surgical crown lengthening and the placement of all-ceramic restorations.&#x0D; Conclusions: This case showed that satisfactory anterior aesthetics can be achieved by comprehensive examination, careful planning of treatment employing a surgical guide, and prosthodontist–periodontist teamwork, even in the complete absence of interdental papillae. &#x0D; How to cite this article: Kılıç D, Alkan BA, Kılıç K.

Sosyal Bilgiler Öğretmenlerinin Argümantasyon Temelli Sosyal Bilgiler Öğretimine İlişkin İnanç ve Deneyimleri

Bu çalışmanın amacı sosyal bilgiler öğretmenlerinin argümantasyon temelli sosyal bilgiler öğretimine ilişkin inanç ve deneyimlerinin ne olduğunu incelemektir. Çalışma 2021-2022 Eğitim öğretim yılı bahar döneminde Güneydoğu Anadolu Bölgesi içerisinde bulunan bir ilde Milli Eğitim Bakanlığı’na bağlı olarak görev yapan öğretmenler ile gerçekleştirilmiştir. Araştırmanın çalışma grubunu 8 kadın ve 13 erkek öğretmen olmak üzere toplamda 21 sosyal bilgiler öğretmeni oluşturmaktadır. Araştırmada; nitel olgu bilim deseni kullanılarak araştırma sorusuna cevap aranmıştır. Araştırmada veri toplama aracı olarak yarı yapılandırılmış ve sesli düşünmeli görüşmeden yararlanılmıştır. Araştırmada öğretmenlerin kendi sosyal bilgiler öğrenme deneyimleri, sosyal bilimlerin doğası ile argümantasyon arasında nasıl bir ilişki kurdukları ve argümantasyon temelli sosyal bilgiler öğretimine yönelik görüşleriyle, görüşlerini etkileyen faktörlerin neler olduğuna odaklanılmıştır. Araştırmanın bulgularına dayalı olarak durumlar arasındaki benzerlik ve farklılıklardan yola çıkılarak, soru-cevapla dersi zenginleştirmek için argümantasyon, küçük sosyal bilimciler gibi düşünmeyi öğretmek için argümantasyon, çocukların kendi sorularını sormalarını desteklemek için argümantasyon, etkin vatandaşlık becerilerin geliştirmek için argümantasyon ve sosyal becerileri geliştirmek için argümantasyon olmak üzere 5 tipleme oluşturulmuştur. Araştırma sonucunda, öğretmenlerin argümantasyon temelli sosyal bilgiler öğretimine ilişkin inanç ve görüşlerinin kendi öğrenme deneyimlerinden, okulun ve sınıfın fiziksel koşullarından, idare ve veli tutumundan, öğrenci seviyesinden, ilgi duydukları alan ve konulardan, uyguladıkları öğretim yöntemlerinin etkililiğine dair düşünce ve deneyimlerinden etkilendiği görülmüştür. Bu sonuçlar ışığında çeşitli öneriler sunulmuştur.The aim of this study is to examine the beliefs and experiences of social studies teachers about argumentation-based social studies teaching. The study was conducted in the spring semester of the 2021- 2022 academic year with teachers working under the Ministry of National Education in a developed province located in the Southeastern Anatolia region. The study group of the research consists of 21 social studies teachers in total, including 8 female and 13 male teachers. In the research, the answer to the research question was sought by using qualitative case science design. Semi-structured and voice-guided interview were used as a data collection tool in the research. In the research, teachers' own social studies learning experiences, how they establish a relationship between the nature of social sciences and argumentation, and their views on argumentation-based social studies teaching, decisively focused on what factors affect their views. Based on the findings of the research and considering the similarities and differences between the situations, 5 different types were created as follows: argumentation to enrich the lesson with question and answer, argumentation to teach how to think like little social scientists, argumentation to support children to ask their own questions, argumentation for the development of effective citizenship skills and argumentation to improve social skills. As a result of the research, it was seen that teachers' beliefs and views on argumentation-based social studies teaching were affected by their own learning experiences, by their beliefs and opinions on the teaching of social studies, by the physical conditions of the classroom and the school administration and the parent stance, by the level of the student, and by the subjects in areas of interest, thoughts and experiences applied from the effectiveness of the teaching methods. Consequently, various recommendations have been presented within the framework of these results

Orthodontic Materials Interacting with Fifth Generation (5G) Electromagnetic Waves

Objective: Public exposure to radiofrequency (RF) fields from fifth generation (5G) and other sources is known to be below human exposure limits. The interaction of RF fields with the human body has been widely documented, with tissue heating being the primary consequence for RF fields above 100 kHz. This study aimed to reveal possible harm to orthodontic patients associated with 5G electromagnetic waves. The possibility of individuals with orthodontic appliances (metallic braces, porcelain braces, thermoplastic appliances) being more affected by 5G was investigated. Methods: Sixty extracted human teeth were divided into 5 groups. Different types of brackets, arch, and ligature wires were applied to each group. Each group was exposed to 5G electromagnetic waves (3.6 GHz of frequency) for 60 minutes. Temperature measurements were made inside the canine root canals and in saline solution. Results: Exposure to a 5G electromagnetic field increased the temperatures of the root canal of the tooth and sodium chloride (NaCl) solution surrounding samples. Temperature increase in the canals were as follows; metal self-ligating braces > mini metal braces > porcelain braces > clear aligner > control. The temperature change in the NaCl solution at the 60th minute was close to each other in the self-ligating braces and mini metal braces groups. The temperature rise of the NaCl solution in the control group was also minimal. Conclusion: The hypothesis that orthodontic materials alter electromagnetic waves is supported by temperature increases. The ferromagnetic density of the orthodontic materials used was shown to be closely connected to temperature increase

Giant variant of acquired perforating dermatosis in a patient with diabetes mellitus

Perforating dermatoses are a group of diseases characterized by transepidermal elimination of dermal components such as collagen, elastin and fibrin. Perforating dermatoses primarily include four main forms: Reactive perforating collagenosis, elastosis perforans serpiginosa, perforating folliculitis and acquired perforating dermatosis. There is limited data about perforating dermatoses in the literature. Because of their rare appearance, they can be easily misdiagnosed. Acquired perforating dermatosis is a systemic disease such as diabetes and chronic renal failure; and it should be considered in case of pruritic papulonodules and giant plaques with central crater in a patient. In addition to the treatment of underlying disease in the first stage; narrow band ultraviolet B (nbUVB) is evaluated to be effective in these cases. Based on its rare occasions, we submit a giant variant of acquired perforating dermatosis with a collagen fiber predominant elimination pattern, which is treated with nbUVB
