Self-Directed Learning Scale (SDLS) developed by Lounsbury, Levy, Park, Gibson, and Smith (2009) was used for determining individuals' self-directed learning. The purpose of this study was to translate the SDLS into Turkish and to investigate its reliability and validity with a sample of 272 university students. The SDLS, the Modified Schutte Emotional Intelligence Scale (MSEIS), Self-Directed Learning Inventory (SDLI), and the Causal Uncertainty Scale (CUS) for determining convergent validity was applied to the participants. Factor analyses results verified the uni-dimensionality of the scale. The test-retest correlation of SDLS was 0.82, whereas Cronbach alpha coefficient of the scale was founded as 0.85 in the reliability analyses. Correlation coefficients representing for convergent validities varied from -0.30 to 0.72 (p < .01) and criterion validity of the scale was determined as 0.236 when cumulative GPA was used as criterion in the assessment of concurrent validity. The findings suggest that the Turkish adaptation of SDLS is a valid and reliable tool to measure self-directed learning in Turkish samples.

Radiküler kist, çenelerde görülen en yaygın lezyonlardan biridir. Çürük veya travma sonucu gelişen pulpal nekrozu takiben, devital olan dişin apeksinde oluşur. Radiküler kistlerin çoğu genellikle asemptomatik ve küçüktür, nadiren büyük boyutlara ulaşabilir. Bu makalenin amacı; maksillar sinüsü kaplayan, orbita tabanına ve burun yan duvarına kadar ulaşmış bir radiküler kist vakasının, lokal anestezi altında cerrahi olarak enükleasyonunu sunmaktır.

Radicular cysts are the most common inflammatory cysts of the jaws. Surgical intervention aims to eliminate periapical pathology in order to allow bone regeneration and healing of periapical tissues. Autologous platelet-rich fibrin is a healing biomaterial in oral surgical defects with the new perspective of accelerated healing. Titanium-prepared platelet rich fibrin (T-PRF) is a third-generation platelet concentrate developed to overcome the harmful effects of silica in glass tubes and also has a longer resorption rate. The purpose of this case report is to present the effects of T-PRF applied to the bone defect that occurs after the enucleation of the radicular cyst. A significant increase in bone density was observed after eight months of follow-up. T-PRF has been shown to be effective in the treatment of bone defects. Therefore, it is thought that it can be used as the only regenerative material in the treatment of bone defects.

Despite many scientific studies on the subject of fracture healing, the effective treatment of lesions in this tissue is still a major problem. Although there have been recent remarkable developments in the treatment methods applied, they remain insufficient for the complete treatment of lesions occurring in bones. Fracture healing is a regenerative process that includes the proliferation of mesenchymal cells, chondrogenesis, angiogenesis and bone formation. Different systemic and local variables which affect the regaining of the physical and mechanical properties of the bone tissue where the lesion has occurred play a role in this process. In the light of previous scientific research, the aim of this paper was to provide information about the options for different applications to be able to obtain rapid treatment through an understanding of the many complex processes in fracture healing.
