    Plagiarism, taking written material such as language, thoughts, ideas, or expressions of other authors without adequate citation or representing of them as one's own original work, is one of the most common types of misconduct in a scientific publication.1 According to Wager,2 there is a difference between a standard phrase and original use. Standard phrases such as “The specimens were mounted in the custom jig of a universal testing machine” or “The specimens were divided into three groups (n=10) according to surface treatments” should not be accepted as plagiarism, although all these examples contain more than 6 words and may be seen verbatim in many texts. We, as the editors, must distinguish between standard phrases and original usage when considering plagiarism. In addition, major plagiarism is being decribed as copying of >100 words without citation and copying of <100 words is named minor plagiarism.2 Even when the author use his/her own words from a previous paper in a new manuscript, he/she should limit this into 30% rule in order to stay away from self-plagiarism.3 Nevertheless, Habibzadeh and Shashok advocated that many paper has been published in a year and it will not be possible to prevent text similarity in the near future.4 In Cumhuriyet approach, authors have to be encouraged to write their own sentences rather than simply copy from other sources. Cumhuriyet Dental Journal announces that every accepted manuscript will be routinely monitored for plagiarism by using the iThenticate software program. I owe a 'Thank you' to every author of Cumhuriyet Dental Journal for their hard work to avoid unethical approach in their paper. Hope to meet in the next issue. Assoc.

    Objectives: With conflicting results in the literature and various manufacturer recommendations, implant restorative cements can provide inadequate retention on implants, especially short or single implants. The aim of this study was to evaluate and compare the retentive properties of six different implant restorative cements on titanium surface. Materials and Methods: A total of 120 titanium rods of specimens (10 mm in length and 12 mm in diameter) were divided into 6 experimental groups (n=20) and six different cements were compared: Adhesor (A), Adhesor Carbofine (AC), Cavitan Cem (CC), Meron (M), Implacem (IM), and MIS Crown Set (MIS). Specimens were subjected to shear bond strength test by a universal testing machine with a crosshead speed of 1 mm/min. The data were analyzed with Kruskal-Wallis and Mann-Whitney U tests (α=0.05). Results: The highest mean bond strength was observed in specimens of group MIS, and followed by specimens of group AC. The adhesive failure mode was predominantly observed in all groups. Conclusions: Different cements on titanium surfaces provide different retention levels. Resin cement is the cement of choice for the definitive non-retrievable cementation of crown copings to implant abutments

    Magnet-retained sectional definitive obturator for an infrastructure maxillectomy patient with limited jaw opening: A clinical report

    A limited oral opening can be a significant problem for patients who must wear removable dental prostheses while inserting or removing prostheses. The treatment of a patient with an infrastructure maxillectomy due to adenoid cystic carcinoma is presented in this clinical report. A sectional obturator prosthesis retained by magnets was fabricated to deal with trismus, fibrosis, and microstomia. The patient’s esthetic and functional expectations were satisfied. The new generation of magnets with improved technology provide sufficient denture retention for clinical application. However, further follow-up may be necessary to ascertain the long-term usefulness of the magnet-retained obturator prosthesis, because, not only the deformation of the silicone material may continue to progress but also loss of magnetism can occur because of corrosion

    Impact of Reducing Irritative Symptoms in Non-Muscle Invasive Bladder Cancer During BCG Instillation: A Pilot Study

    Get PDF
    INTRODUCTION: We evaluated use of anticholinergics, mirabegron, and combination of anticholinergics with mirabegron during Bacillus Calmette-Guérin (BCG) instillation for reducing irritative symptoms in patients with non-muscle invasive bladder cancer (NMIBC). METHODS: Prospectively recorded data of NMIBC patients receiving BCG were retrospectively evaluated between August 2015 and April 2019. Patients with low-grade T1 solitary papillary lesions <4 cm were included in the study. Validated questionnaires (OAB-V8) for irritative symptoms adapted to Turkish language, and QoL index forms were filled out by the study participants. OAB-V8 scores of ≥8 were considered as an indication to start medical treatment for irritative symptoms. Groups were formed according to daily used anticholinergic drugs and combinations as follows: Group 1, tolterodine; Group 2, solifenacin 5mg; Group 3, mirabegron, and Group 4, mirabegron with solifenacin 5 mg. RESULTS: Mean follow- up period was 20.4+-6.8 months. There were 132 patients [110 men (83%) and 22 (17%) women] with irritative symptoms and NMIBC. Mean age of the study population was 59.7+-12.4 years. The OAB-V8 scores and QoL indexes significantly improved with all drugs. However, in subgroup analyses, Group 4 provided the most dramatic improvement in OAB-V8 and QoL index scores (P=0.02 for both). The longest in time to micturition was recorded in Group 4 (P=0.04). Tumour recurrence was similar for groups 12 months after BCG instillation (P=0.9), however the least recurrence was observed in Group 4. DISCUSSION AND CONCLUSION: Combination of solifecacin and mirabegron can reduce irritative symptoms, improve QoL, and prolong time to micturition, during BCG instillation in selected NMIBC patients. This combination may also decrease recurrence rates in this patient population

    <p>Abstract</p> <p>Background</p> <p>Bone marrow-derived circulating progenitor cells (BM-CPCs) in patients with coronary heart disease are impaired with respect to number and mobilization. However, it is unknown whether the mobilization of BM-CPCs depends on the number of diseased coronary arteries. Therefore, in our study, we analysed the correlation between the diseased coronary arteries and the frequency of CD34/45+ BM-CPCs in peripheral blood (PB) in patients with ischemic heart disease (IHD).</p> <p>Methods</p> <p>The frequency of CD34/45<sup>+ </sup>BM-CPCs was measured by flow cytometry in 120 patients with coronary 1 vessel (IHD1, n = 40), coronary 2 vessel (IHD2, n = 40), coronary 3 vessel disease (IHD3, n = 40) and in a control group of healthy subjects (n = 40). There was no significant difference of the total number of cardiovascular risk factors between IHD groups, beside diabetes mellitus (DM), which was significantly higher in IHD3 group compared to IHD2 and IHD1 groups.</p> <p>Results</p> <p>The frequency of CD34/45<sup>+ </sup>BM-CPCs was significantly reduced in patients with IHD compared to the control group (CD34/45<sup>+</sup>; p < 0.001). The frequency of BM-CPCs was impaired in patients with IHD3 compared to IHD1 (CD34/45<sup>+</sup>; p < 0.001) and to IHD2 (CD34/45<sup>+</sup>; p = 0.001). But there was no significant difference in frequency of BM-CPCs between the patients with IHD2 and IHD1 (CD34/45<sup>+</sup>; p = 0.28). In a subgroup we observed a significant negative correlation between levels of hemoglobin AIc (HbAIc) and the frequency of BM-CPCs (CD34/45<sup>+</sup>; p < 0.001, r = -0.8).</p> <p>Conclusions</p> <p>The frequency of CD34/45<sup>+ </sup>BM-CPCs in PB is impaired in patients with IHD. This impairment may augment with an increased number of diseased coronary arteries. Moreover, the frequency of CD34/45<sup>+ </sup>BM-CPCs in ischemic tissue is further impaired by diabetes in patients with IHD.</p
