The aim of this study was to determine the prevalence of congenital tooth deficiencies in permanent teeth (except for the third molars)in the Elazığ province children. In this study, panoramic radiographs of 969 children (473 girls, 496 boys) aged between 8 and 15 years who were admitted to the Department of Pediatric Dentistry of Dentistry Faculty were retrospectively examined. The data obtained from the study were analyzed using descriptive statistics and the Chi-square test and p

Amaç: Bu anket çalışmasının amacı; stajlarda çocuk hasta bakan diş hekimliği fakültesi öğrencilerinin, koruyucu diş hekimliği de içerisine alan çocuk diş hekimliğine yaklaşımını değerlendirmektir. Gereç ve Yöntemler: Amaca yönelik olarak 20 sorudan oluşan bir anket formu hazırlandı ve anket, öğrencilere sınav ortamından uzak stressiz bir ortamda online olarak uygulandı. Veriler bilgisayar ortamında kodlandı ve analiz edildi. Bulgular: Katılımcıların %55,9’u çocuk hasta bakmayı sevdiklerini belirtmişlerdir. %72,8’i çocuk hasta bakarken tedirgin olduğunu belirtirken, %16,9’u çocuk, %83,1’i yetişkin hastayı tedavi etmeyi tercih etmektedir. . Mezuniyet sonrasında meslek hayatlarında rutin olarak çocuk hasta tedavi etmeyi, %67,6’sı çok sık olmamakla birlikte düşünebilirim yanıtını verirken, %25’i evet, %7,4’ü ise mecbur kalmadıkça kesinlikle düşünmüyorum yanıtını vermiştir. Çocuk hasta bakarken kadınların daha tedirgin olmasına rağmen, çocuk hasta bakmayı erkelere göre daha çok tercih etmektedir (p0,05). Katılımcıların sınıflarına ve cinsiyete göre çocuk diş hekimliği hizmetinin en iyi verildiğini düşündükleri kurumlara ilişkin değerlendirmelerinde istatistiksel olarak anlamlı bir farklılık bulunmamaktadır (p>0,05). Her iki sınıf ve cinsiyet için en sık verilen yanıt diş hekimliği fakülteleri olmuştur. Sonuç: Ülkemizde çocuk ve genç nüfusunun fazla olmasına rağmen, geleceğin diş hekimi adayları, bu tedavilerde yeteri kadar istekli olmadıkları görülmüştür. Öğrenimleri süresince çocuk hastaları tedavi etmeye yönelik bilgi ve tecrübelerinin arttırılması, ileride daha çok sayıda çocuk hastayı tedavi edilebilmelerine yardımcı olacaktır.

The aim of this study was to evaluate the bond strength of three different calcium silicate based cements (Biodentine, NeoPutty and MTA Cem LC) with two different bulk fill composites (fiber-reinforced and non-fiber-reinforced). Plexiglas molds with a diameter of 4 mm and a thickness of 2 mm were prepared (n=60). Each CBC was mixed according to the manufacturer’s instructions and placed in plexiglass molds. The BD, NP, and MTA Cem LC samples were then randomly divided into 2 subgroups containing 10 samples each. The surfaces of the samples were air dried and Single Bond universal adhesive was applied. Then, cylindrical plastic capsules of 2 mm height and 2 mm inner diameter belonging to Filtek Bulk fill and EverX Posterior composite resin groups were centered on the coating material and polymerized for 20 seconds. After SBS testing, all samples were examined by scanning electron microscopy (SEM) to identify failure patterns. Three samples, one from each group, were prepared to evaluate the chemical compositions of the materials. Samples were prepared using plexiglass molds with a diameter of 10 mm and a thickness of 2 mm. The materials were then examined with an energy dispersive X-ray spectroscopy for surface elemental analysis. The values obtained from the tests were evaluated as statistically significant (p < 0.05). After SBS testing, the difference between all CBCs was statistically significant in both compound groups. According to the findings obtained from this study, it was concluded that MTA Cem LC had the highest SBS values in both composite groups.

Aim This in vivo study aimed to examine the systemic effects of contemporary calcium silicate cements (CSC) contain different radiopacifiers in rats. Materials & Methods Polyethylene tubes filled with BIOfactor MTA (BIO), Neo MTA Plus (NEO), MTA Repair HP (REP), Biodentine (DENT) and empty tubes (control group) were implanted into the subcutaneous tissues of 80 male Spraque Dawley rats for 7 and 30 days (n = 8). After 7 and 30 day, samples of liver and kidney tissues were submitted to histopathological analysis. Blood samples were collected to evaluate changes in hepatic and renal functions of rats. Wilcoxon and post hoc Dunn Bonferroni tests were used to compare between the 7th and 30th days in order to evaluate the histopathological data. Paired-sample t-test was used to compare laboratory values between the 7th and 30th days, ANOVA analysis and a post hoc Tukey test were used to compare values between groups (p < 0.05). Results On the 7th day, REP, BIO and NEO groups were statistically similar in kidney tissue and the degree of inflammation was found to be significantly higher in these groups compared to the control and DENT groups. On the 30th day, the degree of inflammation of the REP and NEO groups in the kidney tissue was found to be significantly higher than the control, BIO and DENT groups. Although the inflammation in the liver was moderate and mild on the 7th and 30th days, no statistically significant difference was observed between the groups. Vascular congestion was evaluated as mild and moderate in kidney and liver in all groups, and no statistically significant difference was observed between the groups. While there was no statistically significant difference between the groups in the 7th day AST, ALT and urea values, when the creatinine values were compared, the DENT and NEO groups were found to be statistically similar and significantly lower than the control group. On the 30th day, ALT values were statistically similar between the groups. The AST values of the BIO group were found to be significantly higher than the DENT group. While BIO, DENT, NEO and control groups had statistically similar urea values, the REP group was found to be significantly higher than the other groups. The creatinine value of the REP group was significantly higher than the groups other than the control group (p < 0.05). Conclusion CSCs with different radiopacifiers had similar and acceptable effects on the histological examination of the kidneys and liver systemically, and serum ALT, AST, urea, creatinine levels.
