    Investigation of Effects of Essential Oil from Berries of Juniperus excelsa Bieb. Subsp excelsa (Cupressaceae) on Angiogenesis in Shell-less Chick Embryo (CAM) Culture

    The aim of this study was to investigate the effect of essential oil of the berries from Juniperus excelsa Bieb. subsp. excelsa (Cupressaceae) to the vascularization systems of the chick embryos in a chorioallantoic membrane model. The berries of J. excelsa were subjected to hydrodistillation. 50 mu l of essential oil were applied to the center of the blastodisc using a precision micropipette prior to the transfer of shell-less cultures to the incubator. Antiangiogenic effect of essential oil of the study plant was determined with the use of the chick chorioallantoic membrane model. Numbers of main, branching and capillary blood vessels were counted. In the statistical analysis, when the groups were compared with regard to the main blood vessel (MBV) and branch blood vessel (BBV) development, no significant difference (p>0.05) was observed. However, when the groups were compared with regard to capillary vessel (CV) development, the difference between the data of the groups was found significant (p<0.05). This study examined the effect of exposure J. excelsa essential oil on extraembryonic vascular development in the chick embryo area vasculosa (AV) in shell-less culture for the first time. Essential oil of the berries from J. excelsa has antiangiogenic effect.

    ENDODONTİK TEDAVİ SIRASINDA SODYUM HİPOKLORİTİN YANLIŞLIKLA APİKALDEN YUMUŞAK DOKULARA EKSTRÜZYONU: OLGU BİLDİRİMİ
    (2019-12-01T00:00:00Z) Yuca Öztürk, Tuğçe; Alim, Betül Aycan; Güneşer, Mehmet Burak; UYSAL, BETÜL AYCAN
    Kök kanal tedavisi sırasında en çok kullanılan irrigasyon solüsyonu sodyum hipoklorittir. Sodyum hipokloritin antimikrobiyal özelliğine ek olarak en önemli avantajı iyi bir organik doku çözücü olmasıdır. Endodontide %0.5–6 konsantrasyon aralığında kullanılmaktadır ve yüksek konsantrasyonlarda, canlı dokular için son derece toksiktir. Dikkatsiz kullanımı ya da hastada mevcut olan anatomik/patolojik değişiklikler sonucu sodyum hipoklorit apikalden ekstrüze olabilir. Toksik etkisi nedeniyle dokuda ülserasyon, sinir hasarı, nekroz ve bazen geri dönüşümsüz hasarlara yol açabilir. Bu nedenle hastanın klinik ve radyolojik muayenesini detaylı yapmak, irrigasyon aşamasında dikkatli olmak ve oluşabilecek bir komplikasyonu yönetebilmek önemlidir.

    Evaluation of Different Root Canal Filling Techniques in Severely Curved Canals by Micro-computed Tomography
    (2019-09-01) Alim, Betül Aycan; Garıp Berker, Yıldız; UYSAL, BETÜL AYCAN
    AimTo fill the severely curved root canals with different filling techniques and to compare these techniques using micro-computed tomography (micro-CT).Materials and methodsSixty extracted mandibular first molars (degree of root canal curvature > 25°) were selected. All samples were divided into four groups and filled with one of the following techniques: lateral condensation, single-cone, continuous-wave obturation, and core carrier. After they were scanned by micro-CT, the total area, filled area and void area of the root canal were calculated. The Mann–Whitney U and Kruskal–Wallis tests were used for statistical analysis (p<0.05).ResultsIt was shown that significantly more filling material was used in the lateral condensation and core carrier technique groups at 2 and 5 mm than in the single-cone and continuous-wave obturation technique groups (p<0.05). It was observed no statistically significant difference at 8 mm (p > 0.05).ConclusionNo technique could completely fill in root canal. Regarding the coronal part, all techniques can be used for more effective filling as long as a good condensation is achieved. The use of a plugger with an optimal size according to the localisation of root canal curvature and the choice of a heat-resistant root canal sealer affects the success of the treatment in the thermoplastic techniques.
