Objective: The COVID-19 disease, which is caused by the SARS-CoV-2 infectious agent, is the last member of infectious diseases. Factors such as uncertainties about the prognosis of the disease, insufficient control measures, lack of effective therapeutic mechanisms can cause negative effects on individuals’ daily living activities and mental health. In this study, it was aimed to evaluate the mood changes and Mediterranean diet adherence of individuals during the COVID-19 pandemic. Methods: The study was carried out between November 2020 and January 2021 with individuals over 18 years of age. The data required for the research were collected with an online questionnaire. The COVID-19 Phobia Scale (C19P-S) and the Coronavirus Anxiety Scale (CAS) were used to assess the emotional state of individuals. The Mediterranean Diet Adherence Screener (MEDAS) was used to examine the adherence to the Mediterranean diet. Results: A total of 6609 individuals between the ages of 18-70 participated in the study and 70% of the participants are female.

Objective: The goal of this study was to examine the effect of in vivo melatonin (MEL) administration on isolated thoracic aorta in rats with thyroxine treatment and its duty in aortic response to contractile agents, such as potassium chloride (KCl) and phenylephrine (PE). In addition, immunohistological alterations were also examined. Methods: Experimental groups were as follows: control group (n= 5), thyroxine group (n= 5), melatonin group (n= 6), and thyroxine + melatonin group (n= 6). L-thyroxine was given by intraperitoneal (i.p) administration at 0.3 mg/kg/day for 14 days. MEL was administered i.p., at 3 mg/kg/day for 14 days. The thoracic aorta was isolated from rats euthanized by cervical dislocation. Then, vascular rings were prepared. Concentration-response curves for KCl and PE applications were recorded in an isolated organ bath. Tissue samples were fixed in 10% formalin for histopathological and immunohistological evaluation. Results: KCl and PE-induced contractions were reduced significantly in the thoracic aortic rings of the thyroxine-treated rats. MEL administration partially attenuated the reduction in the contraction responses due to thyroxine treatment. Immunohistological findings showed that MEL inhibits the thickening of the vessel wall by probably suppressing collagen formation due to thyroxine treatment in the aortic tissue. Conclusion: Our results suggest that MEL may attenuate the decrease in vascular resistance caused by thyroxine treatment.
目的:研究体内给药褪黑素(MEL)对甲状腺素治疗大鼠离体胸主动脉的影响及其在主动脉对收缩剂如氯化钾(KCl)和苯肾上腺素(PE)的反应中的作用。此外，还检查了免疫组织学改变。方法:试验组分为对照组(n= 5)、甲状腺素组(n= 5)、褪黑素组(n= 6)、甲状腺素+褪黑素组(n= 6)， l -甲状腺素按0.3 mg/kg/d腹腔注射，连用14 d。MEL以3 mg/kg/天的剂量ig给药，连用14天。对颈椎脱位安乐死大鼠进行胸主动脉分离。然后制备血管环。在离体器官浴中记录KCl和PE应用的浓度-响应曲线。将组织样本固定在10%福尔马林中进行组织病理学和免疫组织学评估。结果:甲状腺素治疗大鼠胸主动脉环KCl和pe诱导的收缩明显减少。MEL的使用部分减弱了甲状腺素治疗引起的收缩反应的减弱。免疫组织学结果显示，MEL可能通过抑制主动脉组织中甲状腺素治疗导致的胶原形成来抑制血管壁增厚。结论:MEL可减轻甲状腺素治疗引起的血管阻力下降。

Objective: This research was carried out to determine the attitudes of individuals who applied to primary care during the coronavirus disease-2019 (COVID-19) pandemic and the factors affecting the COVID-19 vaccine. Methods: The descriptive study was conducted with individuals (n=190) who applied to five family health centers in Erzincan city center between March-June 2021. The data were collected using the "Personal Information Form" and the "Scale of Attitudes towards the COVID-19 Vaccine" by paying attention to the pandemic rules by face-to-face interview method. Results: It was determined that 75.3% of the individuals were women, 41.1% were primary school graduates, 59.5% lived in a nuclear family and 74.2% had no chronic disease. Individuals Attitudes Towards COVID-19 Vaccine Scale mean score was 3.26±0.78 out of 5, positive attitude sub-dimension mean score was 3.32±0.99, and negative attitude sub-dimension mean score was 3.21±0.71. There is a statistically significant difference between the mean scores of the Attitudes Towards COVID-19 Vaccine Scale and the status of individuals thinking that COVID-19 vaccine is necessary for public health, worrying about getting COVID-19 infection, having COVID-19 vaccine, and following information about COVID-19 vaccine. Conclusions: It was determined that the attitudes of these individuals towards the COVID-19 vaccine were at a positive level. The reasons for participants' concerns about the COVID-19 vaccine are fear of side effects of the vaccine and the production of the vaccine in a very short period of time.

Objective: Sphenoid sinus is an irregular cavity in the skull and sphenoid sinus pneumatization (SSP) is a variation of the sphenoid sinus that can observe on the radiographs when it reaches large sizes. It is aimed to evaluate the prevalence of SSP in panoramic radiographs in this study.
Methods: Panoramic radiographs of 500 patients were performed in this study. The patients who applied to our department with miscellaneous dental complaints were over the age of 14. The gender and age of the patients were recorded and the right, left, or bilateral visibility of SSP was examined. The study subjects were classified into four age categories and SSP prevalence was evaluated with gender, age, and visibility by statistical analyses.
Results: Female patients were more than males (78%, and 22% respectively). SSP was found in approximately one-third of the patients (33%) in the panoramic radiographs. Of these, 69 (41.8%) were on the right only, 40 (24.2%) on the left only, and 56 (33.9%) were bilateral. SSP was more common in women (24.2%) and was mostly detected in group 2 (14.4%). Any significant difference was not found in terms of right, left, and bilateral SSP, gender, and age groups. (p ›.05).
Conclusion: SSP can be superposed in the zygomatic arch as a radiolucency that can be misdiagnosed as a cyst. SSP was observed in approximately one-third of patients in this study so dentists should be aware of superimposed surrounding structures of the maxillofacial region for accurate diagnosis.

Objective: The Hall Technique is one biological strategy for sealing carious lesions with preformed metal crowns in primary molars. This study aimed to compare the Hall Technique's survival rate with conventional compomer restorations in caries management in primary molars for 60 months. Methods: Children with preformed metal crowns placed with Hall Technique and conventional compomer restorations were invited to Pediatric Dentistry Clinics for a 60-month follow-up. The restorations of these children were evaluated clinically and radiographically. Dental health records of 12 and 24-month follow-up appointments were obtained from the electronic archive. The survival rate of the restorations was evaluated by Kaplan-Meier analysis and the success/failure of the restorations by the Chi-Square test. Restorations with finding such as secondary caries, pulpitis, restoration wear/fracture/loss, crown perforation, inter-radicular radiolucency, and internal root resorption were scored according to major and/or minor failure criteria, while satisfactory ones were scored as successful. Results: Twenty-six primary molars were included in the study. There was no significant difference in the survival rates of preformed metal crowns placed with the Hall Technique (92.3%) and conventional compomer restorations (84.6%) at 60-month follow-up (2 = 2.455, p = .48). The Hall Technique (84.6%) was found significantly more successful clinically and radiographically compared to conventional compomer restorations (23.1%) according to the success or failure criteria in 60-month follow-up (p < .01). Conclusion: The Hall Technique was clinically and radiographically more successful than conventional compomer restorations according to the success or failure criteria at 60-month follow-up. The Hall Technique had a similar survival rate to the conventional compomer restorations as well as low failure findings in caries management in primary molars.

Objective: This study aimed to investigate the effect of low-temperature degradation (LTD) in phase transformation and biaxial flexural strength of high-translucent yttria partially stabilized zirconia (Y-PSZ) and yttria tetragonal zirconia polycrystalline (3-YTZP).
Methods: A total of 120 new high-translucent 3-YTZP (NMS) and Y – PSZ (KST, KUT, NQ3MS) zirconia disc specimens were manufactured according to ISO 6872 for biaxial flexural strength (14 mm., 1.2 ± 0.02 mm). The specimens from each type of material were divided into 3 subgroups (n:30) according to the LTD in an autoclave at 134 C0 at 2 bar (n:10) (at 5, 20 hour (h)). Specimens without LTD served as the control. Data of the monoclinic phase changes (Xm) and flexural strength were analyzed using two-way ANOVA followed by post hoc MannWhitney U test. Weibull statistics were used to analyze strength reliability.
Results: LTD increased the monoclinic content significantly for NMS and slightly for the KST group. A monoclinic phase was not detected for KUT and NQ3MS groups. The biaxial flexural strength of the NMS group was affected significantly and decreased with an increase in the 20 h aging. For flexural strength values, there was no significant difference in aging times for each of the KST, KUT, and NQ3MS groups. Weibull analysis showed the highest characteristic strength for NMS (1412.9), KST (750.1), NQ3MS(790.5) and KUT (615.2) groups. The Weibull modulus (m) increased in the NMS, KUT, and NQ3MS groups compared with the control group and decreased in the KST group.
Conclusion: LTD caused a significant decrease in the biaxial flexural strength results of the NMS group but did not significantly affect the KST, KUT, and NQ3MS groups’ values.

Objective: This research was conducted to identify the relationship between the chronotypes of nurses working in shifts and the quality of their lives. Methods: The research sample that was designed as a descriptive study comprised 267 nurses working in shifts. The research data were collected with the descriptive survey form, the Morningness–Eveningness Questionnaire, and the Short-Form Health Survey (SF-36). Results: As per the breakdown of the nurses by chronotype, 68.9% of the nurses were intermediate-type (n=184), 15.7% of the nurses were morning-type (n=42), and 15.4% of the nurses were evening-type (n=41). The evening-type nurses had a higher number of night shifts than the morning-type nurses (p
