1.ÖZET İnley - Onley Restorasyonların Simantasyonu Sırasında Önısıtma Uygulamasının Klinik Başarıya Etkisi Şeyda Aygün Emiroğlu, Buket Akalın Evren, Protetik Diş Tedavisi ABDAmaç: Bu çalışmanın amacı farklı sıcaklıklara ısıtılan iki farklı rezin siman ile yapıştırılan inley-onley restorasyonların klinik performansını ve marjinal adaptasyonunu değerlendirmektir. Gereç ve Yöntem: Çalışmanın klinik değerlendirme bölümünde, 101 adet IPS e.max restorasyon (83 onley, 18 inley) 51 hastaya uygulanmıştır. İki rezin siman [G-Cem Automix (self-adeziv) ve Variolink N, high viscosity (etch-rinse)], 3 simantasyon ısısında (25 0C, 37 0C, 54 0C) uygulanmıştır. Tüm restorasyonlar 1 hafta, 6 ay ve 1 yıl sonunda 2 gözlemci tarafından modifiye USPHS kriterleri ile değerlendirilmiştir. SEM incelemeleri için restorasyon uygulanan dişlerden vestibül yüzeyinde minede marjini olan 30 ekstensiv onley belirlenmiştir. Simantasyondan sonra 1. hafta ve 12. ayda ölçüler alınıp epoksi replikalar hazırlanmıştır. Replikalar üzerinde yer alan marjinler SEM’de (x200) incelenmiştir. Marjinal adaptasyon kantitatif olarak devamlı marjin yüzdesi şeklinde hasaplanmıştır ve marjinal siman aralığı ölçülmüştür. Bulgular: Variolink ve G-Cem siman gruplarının 1 yıllık değerlendirme periyodu sonundaki total yaşam ömürleri sırasıyla %100 ve %93,8’dir. G-Cem ile gerçekleştirilen simantasyonlarda her sıcaklık grubundan 1 adet olmak üzere toplam 3 desimantasyon gerçekleşmiştir. Bir yıllık klinik kullanım sonrasında modifiye USPHS kriterlerine göre Variolink gruplarının ve 37 0C G-Cem grubunun marjinal adaptasyon skorlarında istatistiksel olarak anlamlı bir farklılık oluşmazken 25 0C ve 54 0C G-Cem gruplarının skorlarında azalma olmuştur (p0,05). Simanları farklı sıcaklıklarda kulanmanın marjinal siman aralığına istatistiksel olarak etkisi olmamıştır (p>0,05). Sonuçlar: Variolink N ile tüm sıcaklık derecelerinde simante edilen inley-onley restorasyonlar, posterior diş defektlerinde güvenli tedavi seçenekleridir. Daha iyi bir marjinal adaptasyon için yapıştırıcı simanı 37 0C’ye ısıtmak etkili bir metod olabilir.

Materials and Methods: In the clinical evaluation section of the study, 51 patients recieved 101 IPS e.max restorations (83 onlays, 18 inlays). Three cementation temperatures 25 0C, 37 0C, 54 0C were tested with two resin cements; G-Cem Automix (self-adhesive) and Variolink N, high viscosity (etch-rinse). All restorations were evaluated after 1 week, 6 months and 1 year by two examiners using modified USPHS criteria. For SEM evaluation, 30 extensive onlay restorations which have margins on the vestibular area located above the CEJ in enamel were evaluated. Impressions were taken with additional silicon impression material 1 week and 12 months after cementation and epoxy resin replicas were prepared. Then the margins on the replicas were evaluated under SEM (x200). Marginal gap width was measured and marginal adaptation was quantitatively evaluated in terms of percentage of continuous margin. Results: After 1 year observation period, total survival rates of Variolink and G-Cem groups were 100% and 93,8% respectively. Three decementations occured with G-Cem group, one from each temperature group. For 1-year clinical service time, no significant difference was noticed in the marginal adaptation of Variolink groups and 37 0C G-Cem group while 25 0C and 54 0C G-Cem groups’ marginal adaptation scores decreased (p0,05). Cements at different temperatures didn’t have significant effects on marginal gap widths. Conclusions: Cementation of inlay and onlay restorations with Variolink N in all temperatures exhibited a reliable treatment option to restore posterior tooth defects. Pre-heating the cement to 37 0C, can be an effective method to have a better marginal adaptation.Key Words: pre-heating, self-adhesive, onlay, marginal adaptation, SE

Education of Healthcare Personnel Working with Pediatric Patients During COVID-19 Pandemic within the Framework of Infection Control
Education of healthcare personnel working with pediatric patients during covid-19 pandemic within the framework of infection control Covid-19 pandemisinde enfeksiyon kontrol çalışmaları çerçevesinde çocuk hastalarla çalışan sağlık personeli eğitimi
© 2020, AVES. All rights reserved.Objective: In the early stages of any epidemic caused by new emerging pathogens healthcare personnel is subject to a great risk. Pandemic caused by SARS-CoV-2, proved to be no exception. Many healthcare workers died in the early stages of pandemic due to inadequate precautions and insufficient protection. It is essential to protect and maintain the safety of healthcare personnel for the confinement of pandemic as well as continuity of qualified healthcare services which is already under strain. Educating healthcare personnel on appropiate use of personal protective equipment (PPE) is as essential as procuring them. Material and Methods: A survey is conducted on 4927 healthcare personnel working solely with pediatric patients from 32 different centers. Education given on PPE usage were questioned and analyzed depending on age, sex, occupation and region. Results: Among four thousand nine hundred twelve healthcare personnel from 32 different centers 91% (n= 4457) received education on PPE usage. Of those who received education only 36% was given both theoretical and applied education. Although there was no differences among different occupation groups, receiving education depended on regions. Conclusion: It is essential to educate healthcare personnel appropiately nationwidely for the continuity of qualified healthcare services during the pandemic
SARS-CoV-2 seropositivity among pediatric health care personnel just after the first peak of pandemic: A nationwide surveillance.
BACKGROUND: COVID-19 pandemic affected every single person on earth one way or the other. The healthcare personnel were no exception, their responsibilities as well as their risks being immense. METHODS: 4927 healthcare personnel all working in pediatric units at 32 hospitals from seven different regions of Turkey enrolled to the study to determine the seroprevalence of SARS Co-V-2 after the first peak wave. Point of care serologic lateral flow rapid test kit for IgM/IgG was used (Ecotest CE Assure Tech. Co. Ltd.). Seroprevalence and its association with demographic characteristics and possible risk factors were analyzed. RESULTS: Nearly 6.1% of healthcare personnel were found to be seropositive for SARS Co-V- 2. Seropositivity was more common among those who did not universally wear protective masks (10.6% vs 6.1%). Having a COVID-19 co-worker increased the likelihood of infection. The least and the most experienced personnel affected more. Most of the seropositive healthcare personnel (68%) did not have any suspicion that they had COVID-19 previously. CONCLUSIONS: Health surveillance for healthcare personnel involving routine point-of-care nucleic acid testing as well as monitoring PPE adherence would be important strategies to protect healthcare personnel from COVID-19 and to reduce nosocomial SARS-CoV-2 transmission
