Finishing and polishing techniques have great importance on the long term success and aesthetics of the composite restorations. In this study it was aimed to examine the effect of three different posterior composites on surface texture with various finishing and polishing procedures. Three different posterior composites, Filtek P60, Clearfil Majesty Posterior and Cavex Quadent Posterior Dense, and three different finishing and polishing procedures diamond finishing burs, tungsten carbide burs and Sof-Lex discs were used in the study. The specimens were 5 mm in diameter and 2 mm in height. The surface roughness was measured at three seperate points with a profilometer device and the Ra values were recorded. A one-way analysis of variance (ANOVA) and Kruskal-Wallis variance analysis was applied for statistical analysis and p < 0.05 was accepted significant. No statistically significant differences were found between the composite resins with respect to surface roughness (p > 0.05). A statistically significant difference was found between the groups of diamond, carbide, and Sof-Lex groups (p < 0.05). Sof-Lex polishing system was more successful than the diamond and carbide burs in the finishing and polishing procedures of composites. SCANNING 38:448-454, 2016. © 2016 Wiley Periodicals, Inc.

The aim of this study was to compare the local and systemic effects of current pulp capping materials containing resin with those of traditional materials in an animal study. A total of 48 rats were used: a control group (n=12) (sub-control and negative control), a resin-containing group (n=18) (Calcimol LC, Theracal LC, Activa-BioActive Base/Liner), and a traditional group (n=18) (Biodentine, ProRoot MTA, Dycal). The materials which had been placed in polyethylene tubes were implanted in subcutaneous pockets. The rats were sacrificed at 1, 2, or 4 weeks. Evaluations were made of subcutaneous connective tissue, the left kidney, liver, and blood samples. Of all the study groups, MTA demonstrated biocompatibility at a level close to that of the control groups. Inflammation was observed to be more severe in resin-containing materials, but Activa Base/Liner showed a more successful local and systemic tissue response.

Aim: To evaluate the bond strengths of pulp capping materials (Dycal, ProRoot MTA, Biodentine, TheraCal LC, Calcimol LC, and ApaCal ART) and different adhesive systems (Gluma 2 Bond, Clearfil SE Protect, Gluma Self Etch, Clearfil S 3 Bond Plus, Gluma Bond Universal, Clearfil S 3 Bond Universal). Materials and Methods: Two hundred fifty-two acrylic blocks were prepared in which cylindrical cavities of 4 × 2 mm 3 were formed. Pulp capping materials were placed in the cavities. Different adhesive systems were applied to each pulp capping material group. After applying the composite resin, the shear bond strength (SBS) values of the specimens were determined in the Instron test device. Fracture types were evaluated using a stereomicroscope and a scanning electron microscope. Data were analyzed by Shapiro–Wilk’s and Kruskal–Wallis H test. Results: There is a statistically significant difference between pulp capping materials in terms of SBS values ( P < .05). Dycal’s SBS was found significantly lower than other materials, and the highest bond strength was observed in Calcimol LC material. Although there is no statistically significant difference ( P > .05) between the adhesive agent groups in terms of SBS, Gluma 2 Bond showed the highest bond strength value. Conclusion: In traditional pulp capping materials such as Dycal, MTA, and Biodentine, using a two-step self-etch adhesive system can result in higher bond strength values. In resin-based TheraCal LC,, ApaCal ART, and Calcimol LC materials, it may be recommended to use a two-step etch and rinse adhesive system.

Dental anksiyete, diş hekimliği uygulamalarına bağlı gelişen streslerin bireyde yarattığı tepki olarak ifade edilmektedir. Dental anksiyeteli bireyler, randevularını erteleyerek geciktirmekte ve hatta diş hekiminden tamamen kaçınmaktadır. Çalışmamızda; Dicle Üniversitesi Diş Hekimliği Fakültesi'ndeki öğrencilerin diş sağlığı ile dental anksiyete arasındaki ilişkinin incelenmesi amaçlanmıştır. Gereç ve Yöntemler: Çalışmaya Dicle Üniversitesi Diş Hekimliği Fakültesi'nden 300 öğrenci dâhil edildi. Katılan öğrencilerin ağız muayeneleri yapılarak, DSÖ'nün diş sağlığı durumunu değerlendirmekte belirlediği DMF-T indeksi kullanılarak hesaplandı. Öğrencilere dental işlemlere karşı anksiyete seviyelerini ölçebilmek için 5 sorudan oluşan Modifiye Dental Anksiyete Skalası (MDAS) anketi uygulandı. MDAS sonuçları ≥19 olan bireyler yüksek anksiyeteli olarak düşünüldü. Bireylerin demografik niteliklerini de içeren veriler istatistik programına aktarılarak değerlendirildi. Bulgular: Erkeklerin MDAS değerleri kadınlara göre anlamlı derecede düşüktür. Yaş grupları arasında DMF-T değerleri bakımından anlamlı farklılık bulunmaktadır. 17-20 yaş aralığındaki katılımcıların DMF-T değeri 26-30 yaş aralığındakilere oranla anlamlı derecede düşük hesaplanmıştır. Sonuç: DMF-T değerleri üst sınıflara gidildikçe, anksiyete verilerinden bağımsız olarak artmıştır. Araştırmamızdan elde edilen diğer verilere göre; kadın katılımcılar erkeklere nazaran anlamlı derecede yüksek anksiyeteye sahip bulunmuştur. Cinsiyet ve sınıftan bağımsız olarak Diş hekimliği eğitiminin erken bir aşamasında müfredata eklenebilecek ''anksiyete tanı ve kontrol yöntemleri'' üzerine bir eğitimin kaygıyı azaltmada yardımcı olacağını düşünmekteyiz.

Purpose Nurses have a very important role in diabetes education of children and adolescents, however, no systematic review has been performed that evaluates the effectiveness of the independent interventions of the nurses. This systematic review aims to identify and assess randomized controlled trials (RCT) that included interventions implemented by nurses to improve glycemic control for children and adolescents with type 1 diabetes. Eligibility Criteria PubMed, the Cochrane Central Register of Controlled Trials, Scopus, Web of Science, Science Direct databases were systematically searched up to 2022. Interventions provided by nurses for any child ≤18 years diagnosed with type 1 diabetes mellitus were included. Sample Seven RCT articles met our review criteria. Results All included studies were published between 2005 and 2021. Studies varied in terms of intervention type; telephone case management, coping skills training, motivational interview as well as home visit education programs. Interventions were found to significantly decrease the HbA1c level in three of seven studies. Conclusions Our systematic review suggests that nurses can improve the glycemic control of children with type 1 diabetes by conducting care interventions. According to current evidence, this study suggests that telephone contact by nurses and motivational interviewing can be beneficial in improving glycemic control in this population. Implications Nurses may encourage children and adolescents with diabetes to engage in self‐management of their glucose levels. There is a need for more randomized controlled studies assessing the efficacy of nursing interventions for children with type 1 diabetes.
