    (WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2022) Duman, Canan; Uslu, Fatih Samet; Çakmak, Sena; Aytekin, Şevval Ilgın; Apaydın, Tuana; Egil, Edibe
    Background: Turkey is hosting the world's largest immigrant population under temporary and international protection. Due to the social inequalities contributing to early childhood dental caries, the effectiveness of dental care service for immigrant children should be evaluated. Aim: To evaluate the accessibility of immigrant and refugee children residing in four different regions of Turkey to oral health products and dental treatment services. Design: A questionnaire consisting of 21 questions was administered: The first six questions elicited demographic data, and the remaining 15 questions asked about oral health habits, access to oral hygiene materials, and dental treatment services. Participants included the parents of 430 children under the age of 18, who were registered with migrant associations in the regions where they lived (Istanbul, Samsun, Hatay, or Ankara). Results: The majority of the participants were from Syria and Iraq. Of the participants, 42.1% reported that their children's oral hygiene habits had changed negatively after they migrated, 71.9% reported that they had not been to the dentist in the last year, and 82.8% reported that they had not been to the dentist for more than 12months. Access to oral and dental hygiene products was not difficult for 68.4%. About 62.6%, however, reported that they had difficulty accessing dental treatment. Conclusion: The findings showed that this disadvantaged group had difficulty accessing dental treatment. Therefore, there is a need for national and international health strategies to ensure that immigrant and refugee children have effective access to dental treatment.

    Antibiotic prescribing practices for prophylaxis and therapy of oral/dental infections in pediatric patients-results of a cross-sectional study in Turkey
    (German Medical Science-Gms, 2023) Capan, Belen Sirinoglu; Duman, Canan; Kalaoglu, Elif Ece
    Aim: Antibiotics are often prescribed for the treatment of various infec-tions and prophylactic purposes in dental practice. Their improper use can cause microbial resistance to antibiotics, which poses a world-wide threat. The aim of this cross-sectional study was to evaluate the knowledge and attitudes of dentists and dentistry students about anti-biotic prescription practices for prophylaxis and the treatment of dental infections in pediatric patients.Methods: A questionnaire was e-mailed to 2,100 dentists and 300 senior dentistry students. The questionnaire was filled out by the par tic-ipants within a 2-month period (May-June 2020). A 30-point scoring system was developed to assess the knowledge levels of the dentists according to the guidelines. Descriptive statistical analyses were per-formed. One-way ANOVA test and the Chi-Squared test were used to compare qualitative variables.Results: The response rate was found to be 24.2% for dentists and 49% for senior dentistry students. 19.4% of the participants were found to be moderately knowledgeable and 80.6% of them were highly know-ledgeable. Students' knowledge scores were found to be higher than the general dentists and other specialists (p<0.05). There was no sig-nificant difference between students and pedodontists. Conclusion: Dentists were found to have sufficient knowledge about the usage of antibiotics in children, but there is still a lack of information about circumstances under which antibiotics should not be prescribed. Dentists and dentistry students should attend continuing education programs to keep their information up-to-date and should also prescribe antibiotics in adherence with the current guidelines to prevent antibiotic resistance.

    (Bmc, 2023) Kalaoglu, Elif Ece; Duman, Canan; Capan, Belen Sirinoglu; Ocak, Mert; Bilecenoglu, Burak
    ObjectivesNew biomaterials had some advantages such as mixing and easier application as compared to traditional MTA in single step apexification method. This study aimed to compare the three biomaterials used in the apexification treatment of immature molar teeth in terms of the time spent, the quality of the canal filling and the number of x-rays taken to complete the process.MethodsThe root canals of the extracted thirty molar teeth were shaped with rotary tools. To obtain the apexification model, ProTaper F3 was used retrograde. The teeth were randomly assigned into three groups based on the material used to seal the apex; Group 1: Pro Root MTA, Group 2: MTA Flow, Group 3: Biodentine. The amounts of the filling, the number of radiographs taken until treatment completion and the treatment duration were recorded. Then teeth were fixed for micro computed tomography imaging for quality evaluation of canal filling.ResultsBiodentine was superior to the other filling materials according to time. MTA Flow provided greater filling volume than the other filling materials in the rank comparison for the mesiobuccal canals. MTA Flow had greater filling volume than ProRoot MTA in the palatinal/distal canals(p = 0.039). Biodentine had greater filling volume more than MTA Flow in the mesiolingual/distobuccal canals (p = 0.049).ConclusionsMTA Flow was found as a suitable biomaterial according to the treatment time and quality of root canal fillings.

    Comparison of Two Aerosol-Free Caries Removal Methods: A Split-Mouth Randomized Clinical Trial
    (Sivas Cumhuriyet Üniversitesi, 2021) Duman, Canan; Kalaoğlu, Elif Ece; Şirinoğlu Çapan, Belen; Egil, Edibe
    Objectives: The management of deep caries lesions in immature permanent molars can be challenging in clinical practice, but minimally invasive caries removal methods can maintain apexogenesis by preventing extensive tissue loss. Here we compare a chemo-mechanical caries removal (CMCR) gel and polymer bur in terms of time spent on caries removal, patient acceptability, and clinical success. Materials and Methods: The teeth of 30 children were randomly divided into two groups. The duration of each method, the level of cooperation during each method, and the child’s choice of caries removal method were recorded. Patients were followed at six-month intervals for at least two years. Results: The difference between the patients’ preferences was not statistically significant, while the average caries removal time of the polymer bur method was significantly shorter (p<0.05) than the CMCR method. The rates of apical closure without pathology in the CMCR and polymer bur groups were 63.2% and 73.7%, respectively; 10% of each group underwent further treatment due to their clinical and/or radiographic pathology. Conclusions: These methods were thought to serve as an interim treatment in managing immature permanent teeth with deep caries. Furthermore, these methods, which do not involve water cooling, can minimize the risk of contamination and cross-infection.

    Evaluation of BIS-GMA Release in Different Types of Composites
    (Erzincan Binali Yıldırım Üniversitesi, Fen Bilimleri Enstitüsü, 2021) Karaca, Serhat; Özdokur, Kemal Volkan; Egil, Edibe; Ceyran, Ertuğrul; Duman, Canan
    BIS-GMA is frequently is involved in the structure of composite materials and may remain unpolymerized after polymerization. Residual Bis-GMA has harmful effects, it is crucial to determine the amounts released monomer from dental materials. The aim of this study is to compare residual BIS-GMA amounts in three types of composite. A total of 45 (n=15) composite (Filtek Ultimate Universal Restorative,3M ESPE,Germany), flowable composite (Nextcomp Flow,Meta Biomed,Kore), bulk fill composite(Tetric N Ceram, Ivoclar,Lichtenstein) cylindrical samples were polymerized in Teflon molds in accordance with the manufacturer's instructions. The samples were placed in 1.5ml ethanol (Carlo Erba, Pharm. Grade, 99.9%) and kept at 37oC. Monomer release of the samples was evaluated on the first, third and seventh days using the High Performance Liquid Chromatography technique. BIS-GMA release was shown with the highest amounts within all groups on the first day. The elution in composite fillings was significantly lower than the other materials on the first day(p<0.05). The highest total emission rates were observed in the flowable composite. The material selected in clinical practice should be considered because the monomer release may vary depending on the composite type.

    (WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2021) Duman, Canan; Al-Batayneh, Ola B.; Ahmad, Sajjad; Durward, Callum S.; Kobylinska, Angelika; Vieira, Alexandre R.; Tredoux, Sheree; Okutan, Alev Eda; Egil, Edibe; Kalaoğlu, Elif Ece; Şirinoğlu Çapan, Belen; Akşit Bıçak, Damla; Zafar, Sobia
    Background: The number of child abuse cases is increasing worldwide; therefore, it is important to educate individuals having contact with children about it. This includes dentists who play a pivotal role in detecting and reporting child abuse. Aim: To identify and compare the final- year dental student‘s knowledge, attitudes, and practice in relation to child abuse. Design: A 38- item and four- part online questionnaire was distributed to students of 11 dental schools in 10 countries. SPSS and GraphPad Prism were used for data analysis. The levels of statistical significance were determined using a chi- square test. P ? .05 was considered to be statistically significant. Results: A total of 660 students completed the survey. Fifty- six percent of the students received formal training on child abuse, and 86% wanted additional training. The knowledge of child abuse was significantly higher in Australia, the United States, and Jordan compared with other countries. Internet (60.3%) was commonly used as an information source for child abuse. Conclusions: The study showed that dental students lack knowledge and experience in recognizing and reporting child abuse. Most respondents indicated a desire for additional training; therefore, dental schools should review what they are currently teaching and make changes as appropriate.

    Siyah Havuç, Vişne ve Nar Konsantrelerinin Streptococcus mutans’ın Biyofilm Oluşturma Özelliği Üzerine Etkisinin Değerlendirilmesi
    (Türkiye Klinikleri Yayınevi, 2021) Egil, Edibe; Duman, Canan; Ünlü, Özge; Demirci, Mehmet; Altan Şallı, Gülay; Özdal Zincir, Özge; Katiboğlu, Ahmet Bülent
    Amaç: Diş çürüğünün önlenmesi amacı ile çürük yapıcı mikroorganizmaların ağız ortamından uzaklaştırılmasında kullanılan antibakteriyel ajanların yan etkileri, insanların sağlık ihtiyaçları için tamamlayıcı ve alternatif tedavilere olan ilgisini artırmıştır. Bu çalışmanın amacı, ülkemizde yetiştirilebilen siyah havuç, nar ve vişne konsantrelerinin; Streptococcus mutans’ın biyofilm oluşturma özelliği üzerine etkisinin değerlendirilmesidir. Gereç ve Yöntemler: Çalışmamızda siyah havuç, vişne, nar konsantreleri (%100) ve S. mutans ATCC 25175 kökeni kullanıldı. Siyah havuç, vişne ve nar konsantrelerinin antibakteriyel aktivitesinin kontrol edilebilmesi için minimal inhibitör konsantrasyon değerleri tespit edildi. Biyofilm oluşturma aktivitesine etkisinin kontrol edilebilmesi için kristal viyole boyama metodu kullanıldı. Bakteriyel süspansiyonlar, Triptik soy broth (Oxoid) besi yeri kullanılarak hazırlandı ve OD (Optical Density) 600 nm’de 0,5 McFarland turbidite standartı (1,5x108 CFU/mL) olacak şekilde hazırlandı. Bulgular: Siyah havuç, vişne ve nar konsantreleri S. mutans’a karşı antibakteriyel etki göstermemiştir. Konsantrelerin S. mutans’ın biyofilm oluşturma özelliği üzerine etkisi incelendiği zaman konsantreler ve negatif kontrol grubu arasında istatistiksel olarak anlamlı farklılık gözlemlenmektedir(p<0,05). Yapılan ikili incelemelerde 24. saatten sonra nar konsantresi, 48 saatten sonra vişne konsantresi ile negatif kontrol grubu arasında istatistiksel olarak anlamlı farklılık gözlemlenmektedir(p<0,008). Siyah havuç ile negatif kontrol grubu arasında 96. saat sonuna kadar istatistiksel olarak anlamlı bir farklılık gözlemlenmemiştir(p>0,008). Sonuç: Siyah havuç konsantresi bakteri çoğalmasını inhibe etmezken, biyofilm oluşumunu 96. saat sonuna kadar baskılamaktadır. Ülkemizde bol miktarda bulunan siyah havucun biyofilm oluşumunu bozucu etkileri göz önünde bulundurularak, çocukların sıklıkla tükettiği sakız, pastil gibi ürünlerin içerisine alternatif etken madde olarak kullanılabilirliği ilerleyen çalışmalarda araştırılmalıdır.
