Publication Open Access Clinical Experience, Knowledge, Attitudes and Practice of Turkish Pediatric Dentists during the COVID-19 Pandemic(MDPI, 2021-10-21) AKYÜZ, SERAP HATİCE; Koc, Yelda; Akyuz, Serap; Aksit-Bicak, DamlaBackground and Objectives: Coronavirus Disease 2019 (COVID-19) is a critical public health problem that has affected all fields, including dentistry. The dental management of children has become even more difficult during the COVID-19 pandemic. The purpose of this study was to evaluate the current knowledge, attitudes and practices of Turkish pediatric dentists who have been providing dental treatments to children during the COVID-19 pandemic. Materials and Methods: After receiving ethical approval, this cross-sectional study was conducted using the Google Forms online survey instrument. An online questionnaire link was sent to all the members of the Turkish Society of Paediatric Dentistry by e-mail and through social media. Statistical analyses were performed using descriptive statistics and Chi-square test; a p-value less than 0.05 was considered statistically significant. Results: A total of 200 pediatric dentists participated in this study and most of them (82%) only performed emergency dental treatments, whereas 18.5% performed both emergency and routine dental practices during the COVID-19 pandemic. The vast majority (72.5%) of pediatric dentists prescribed antibiotics and analgesics to their patients who were not cooperative with non-pharmacological behavior management techniques. The findings of the current study showed that the Turkish pediatric dentists had a good level of knowledge about COVID-19, satisfactorily conducted most of the infection control measures before and after the dental treatments, and attached importance to the use of PPEs; however, infection control measures during the dental treatments could be implemented better. Conclusions: Along with all precautions, the vaccination of healthcare workers and requesting a recent test result from patients showing a lack of COVID-19 disease before dental appointments could be used as effective infection control measures. Additionally, pediatric dentists should continue to follow local and universal guidelines, and education programmes should be frequently implemented in order to keep their COVID-19 management strategies up to date.Publication Open Access In Vitro Fluoride-Release/Recharge Pattern and_x000D_ Antimicrobial Effects of Current Restorative_x000D_ Materials Used in Pediatric Dentistry(2020-04-13) YARAT, AYŞEN; Belen Şirinoğlu ÇAPAN;Serap AKYÜZ;Burçin ALEV;Beste TACAL ASLAN;Tanju KADİR;Ayşen YARATObjective: The aim of this in vitro study was to investigate the fluoride-releasing/recharging and antimicrobial effects of restorative materialsused in pediatric dentistry.Material and Method: High-viscosity and resin-modified glass-ionomercement, glass carbomer, compomer, giomer and composite weretested. Dental materials’ fluoride-release was measured in distilled water(DW) and artificial saliva (AS) for eight weeks using a fluoride-specificelectrode. At the end of eight weeks, specimens were divided intothree groups for recharging with acidulated phosphate fluoride gel andfluoride varnish. After recharge, fluoride release was measured again.Agar diffusion test was used to assess antimicrobial effects againstS. mutans and L. acidophilus. The statistical analysis was done withMann-Whitney U and Friedman tests using SPSS-22 software.Results: High-viscosity glass-ionomer cement showed the highestfluoride-release in both storage media, followed by glass carbomer,while giomer demonstrated the lowest. After recharge, the increasein the varnish group was significantly higher than others (p<0.05).Fluoride-release in DW groups was significantly higher than in the ASgroups for all materials during the test period (p<0.05). None of thematerials showed antimicrobial effects.Conclusion: It was concluded that fluoride-release from glass ionomer-based materials is higher than that from resin-based materials.Fluoride-release from materials decreases in AS. Glass carbomer can beused as an alternative to glass ionomers.Publication Open Access The level of two trace elements in carious, non-carious, primary, and permanent teeth(ISTANBUL UNIV PRESS, ISTANBUL UNIV RECTORATE, 2020-08-13) YARAT, AYŞEN; Kuru, Ruya; Balan, Gulsah; Yilmaz, Sahin; Tasli, Pakize Neslihan; Akyuz, Serap; Yarat, Aysen; Sahin, FikrettinPurpose The boron and fluoride mainly accumulate in the bones and teeth of the human body. The purpose of this study is to determine boron or fluoride levels in the whole tooth, to evaluate the correlation between their levels and to compare these levels in primary/permanent, carious, and non-carious groups. Materials and Methods The boron and fluoride levels of thirty-six teeth, separated such as primary carious (n=9) and non-carious (n=9), permanent carious (n=9) and non-carious (n=9), were determined by ICP-MS and ion-selective electrode, respectively. Results While boron levels were between 0.001 and 5.88 ppm, the fluoride levels were between 21.24 and 449.22 ppm. The boron level of non- carious teeth was higher than those of carious teeth in primary and permanent tooth groups. However, this difference was not statistically significant (p>0.05). The fluoride level of non-carious teeth was higher than those of carious teeth in primary (p=0.062) and permanent teeth groups (p=0.046). Negative correlation, found between boron and fluoride in all groups, was significant only in non-carious teeth group (r=-0.488, p=0.040). Conclusion The results of our study proved the importance of fluoride as a protective factor for dental caries once more. The boron levels in non- carious teeth were also higher than carious teeth. However, it was not significant. Moreover, there was negative correlation between teeth boron and fluoride levels. Therefore, it is necessary to conduct more detailed studies on the tooth boron level and its relation with caries formation and with fluoride levels.
