Background: Dental education is one of the disciplines where students are most significantly affected psychologically. The aim of this study was to evaluate the relationship between spiritual health, resilience and happiness levels of dental students at a state university in Turkey. Methods: This cross- sectional study included 212 students from the 3rd, 4th and 5th grades of the faculty of dentistry. A questionnaire consisting of 4 sections was used in the study. The sections of the questionnaire include students’ general and academic information, Turkish adaptations of the Spiritual Well-Being Scale, The Brief Resilience Scale, and the Oxford Happiness Questionnaire-Short Form. Data analysis was performed with IBM SPSS 25 package program. The Shapiro-Wilk test was used to assess the normal distribution of the data. The Mann-Whitney U test was preferred for comparisons between two categorical variables and one numerical variable. The Kruskal-Wallis H test was employed for comparisons involving two categorical variables and one numerical variable. The presence of a relationship between two numerical variables was examined using the Spearman test. Results: In terms of resilience and happiness scores, males had higher scores than females. It was determined that third graders scored higher than fifth graders in harmony with nature scores, and third graders scored higher than fourth graders in deregulation scores. There was a positive correlation between happiness, spiritual well-being and resilience; a negative correlation between happiness and anomie. There was no significant relationship between age and happiness scores. As a result of multiple linear regression to determine the factors affecting happiness; increases in spiritual well-being and resilience will lead to an increase in happiness levels. Conclusion: This study concluded that increased levels of spiritual well-being and resilience among a group of dental students would lead to increased levels of happiness. However, further research is needed to understand the relationship between mental health, resilience and happiness levels during dental education.

Testing the biocompatibility of commercially available dental materials is a major challenge in dental material science. In the present study, the biocompatibility of four commercially available dental materials Mineral Trioxide Aggregate, Biodentine, Harvard BioCal-CAP and Oxford ActiveCal PC was investigated. The biocompatibility analysis was performed on zebrafish embryos and larvae using standard toxicity tests such as survivability and hatching rates. Comparative toxicity analysis of toxicity was performed by measuring apoptosis using acridine orange dye and whole mount immunofluorescence methods on zebrafish larvae exposed to the dental materials at different dilutions. Toxicity analysis showed a significant decrease in survival and hatching rates with increasing concentration of exposed materials. The results of the apoptosis assay with acridine orange showed greater biocompatibility of Biodentine, Oxford ActiveCal PC, Harvard BioCal-CAP and Biodentine compared to MTA, which was concentration dependent. Consequently, this study has shown that showed resin-modified calcium silicates are more biocompatible than traditional calcium silicates.

Kök malformasyonları çeşitli genetik ve çevresel faktörlerin bir sonucu olarak ortaya çıkabilmektedir. Kök gelişimi sırasında meydana gelen problemler enfeksiyon, travma, kemoterapi veya radyasyon tedavisine bağlı oluşabilmektedir. Yakın zamanda tanımlanan bir dental anomali olan molar keser malformasyonu veya molar keser kök malformasyonu, daimi birinci molar dişlerin köklerinde görülen gelişim bozuklukları ile karakterizedir. Aynı zamanda süt ikinci molar ve maksiller daimi santral keser dişleri etkileyebilmektedir. Molar keser kök malformasyonu veya molar keser malformasyonu, erken çocukluk döneminde maruz kalınan farklı çevresel faktörler sebebiyle diş köklerinin anormal oluşumu ile ilişkilendirilmiştir. Bu anomalinin görüldüğü dişlerden, molar dişler normal kron morfolojisine sahip olup ancak radyografi ile teşhis edilebilirken, keser dişler de kron morfoloji etkilenmiştir. Bu dişlerde herhangi bir çürük veya kron deformitesi olmaksızın enfeksiyon ve periodontal hastalık görülebilmektedir. Tedavi için ilk seçenek, doğru zamanda dişlerin çekimi ve ikinci daimi molar dişlerin oluşan boşluğuna doğru sürdürülmesi olabilmektedir. Malforme kökler ve kalsifiye pulpa dokusu sebebi ile endodontik tedavinin çok zor olduğu belirtilmektedir. Güncel klinik ve radyografik teşhis ve tedavi yöntemlerinin uygulandığı farklı vaka raporları bulunmaktadır. Bu derlemenin amacı, ‘Molar Keser Malformasyonu’ olarak adlandırılan anomalinin güncel literatür ışığında değerlendirilmesidir.

Background The aim of this study was to evaluate the effect of band and loop space maintainers, fabricated using digital technologies, and the luting cements used for their fixation, on mesio-distal tooth movement using the Finite Element Analysis method. Additionally, the biomechanical performance of the materials was analyzed by comparing the maximum Von Mises stress distribution. Methodology: A total of fifteen finite element models were created using combinations of five different band and loop materials (BruxZir, Conventional, Trilor, polyetheretherketone and carbon fiber-reinforced polyetheretherketone) and three types of luting cements: conventional glass ionomer cement, resin-modified glass ionomer cement, and dual-cure resin cement. A vertical force of 70 Newton was applied in the occluso-gingival direction at the band-loop junction in each model. Stress distribution and potential failure zones were analyzed using the finite element analysis method. Results: Among the tested materials, BruxZir exhibited the least amount of displacement and generated the lowest stress on the tooth. It was followed by Conventional, Trilor, and carbon fiber-reinforced polyetheretherketone and polyetheretherketone. Polyetheretherketone showed the highest level of displacement. When comparing luting cements, the resin-modified glass ionomer, which has the lowest elastic modulus, caused the greatest mesial movement. This was followed by the self-adhesive resin cement and the conventional glass ionomer cement. Conclusions: The integration of digital technologies in pediatric dentistry enables the clinical use of space maintainers fabricated from various advanced materials. However, further clinical studies are necessary to assess the long-term success and biocompatibility of these digital materials.

Diş hekimleri meslek hayatları boyunca milyonlarca tedavi kararı vermek zorunda kalmaktadır. Bu kararlar doğrultusunda toplumun ağız ve diş sağlığına yön vermektedirler. Birçok meslektaşım tedavi aşamasına gelmeden dişleri koruma yöntemleri hakkında özellikle lisans öğrenimi sırasında yeterli eğitimi alamamaktadırlar. Ağız ve diş sağlığı birey bazında korunarak toplumun sağlık durumu yükseltilecek ve devlet bütçesinden bu alana ayrılan harcamalarda önemli miktarda tasarruf sağlanacaktır. Bu kitapta, Türkiye’de ağız diş sağlığı uygulamalarının dünü, bugünü ve yarınına ışık tutmak amacıyla, dünyada ve ülkemizde mevcut durumun analizi, sağlık hizmetleri basamaklarında yapılması gereken düzenlemeler ve toplumun ağız diş sağlığını tehdit eden bölgesel ve sistemik hastalıklar incelenmiştir. Toplum ağız ve diş sağlığı hakkında diş hekimlerinin farkındalıklarının arttırılması amaçlanmıştır.
