Abstract
The aim of this study was to evaluate the impact of mini-screw placement on the alveolar ridge using a split-mouth design. Twelve beagles underwent bilateral extraction of their lateral teeth. In the immediate group, a mini-screw was unilaterally placed approximately 3-4 mm below the alveolar crest of the extraction site on the experimental side. The delayed group received mini-screws six weeks after tooth extraction. On average, the dogs were sacrificed after 11 weeks, and the maxillary bones were excised and scanned using cone-beam computed tomography (CBCT). Histopathological examinations were conducted to assess inflammation and bone formation scores. The results showed that in the immediate group, bone height was significantly greater on the intervention side compared to the control side (p < 0.05), whereas there was no significant difference in the delayed group. In both groups, there was a significant increase in bone density around the mini-screws compared to the control sides (p < 0.05). Mini-screw insertion led to a significant enhancement of bone growth in both groups (p < 0.05), with no notable differences between the two groups. The mini-screws did not have any impact on bone inflammation or width. Overall, both immediate and delayed mini-screw placement in the extraction socket positively influenced bone dimensions, density, and histological properties. However, immediate insertion was more effective than delayed placement in preserving vertical bone height, despite delayed insertion resulting in higher bone density.

Abstract
Background/Purpose The COVID-19 pandemic affects social and psychological resources. Healthcare workers, especially dental personnel, are more at risk for mental issues due to anxiety, pressure, and frustration. This study assessed mental health outcomes during the COVID-19 epidemic among Iranian dental care providers, focusing on insomnia, anxiety, depression, and posttraumatic stress disorder (PTSD). Methods In this multicenter cross-sectional survey, the Insomnia Severity Index, the Hospital Anxiety and Depression Scale, and the Global Psychotrauma Screening were masured. Six hundred thirty-eight dental care providers (dental specialists, general dentists, dental hygienists, dental assistants, and dental students) from different parts of Iran (Tehran, Shiraz, Tabriz, and Mashhad) were investigated by the stratified sampling method. The univariate analysis was incorporated as independent in binary logistic regression models to analyze the data. In this study, the significance level was set at 0.05. Results Among all the participants, 42.8% were dental students or residents, 21.9% were general or specialist dentists, 18.7% were dental assistants, and 16.6% were nonclinicians. The prevalence of insomnia, anxiety, and depression was 31.3%, 40.8%, and 54.9%, respectively. The frequency of participants in the low, moderate, and high levels of PTSD resulting from LCA 56.6%, 33.7%, and 9.7%, respectively. Conclusions This study found a significant frequency of mental health issues among Iranian dentists. Females, participants whose relatives have COVID-19, and those with a higher workload were more likely to develop mental health symptoms. As mental problems among dental professionals might affect the quality of patient care, diagnostic, supportive, and therapeutic interventions should be taken.

Abstract
Background Among several potential transmission sources in the spreading of the COVID-19, dental services have received a high volume of attention. Several reports, papers, guidelines, and suggestions have been released on how this infection could be transmitted through dental services and what should be done. This study aimed to review the guidelines in order to develop a practical feasibility protocol for the re-opening of dental clinics and the reorientation of dental services. Methods This study systematically reviewed the published literature and the guidelines of international health care institutions on dentistry and COVID-19. We searched Pubmed, Web of Science, and SCOPUS electronic databases using MESH terms. The recommendations identified were tested with a convenience sample of experienced practitioners, and a practical step-by-step protocol is presented in this paper. Results To the date this paper was drafted, 38 articles were found, of which 9 satisfied our inclusion criteria. As all the nine studies were proposed in a general consensus, any elective non-emergency dental care for patients with suspected or known COVID-19 should be postponed for at least 2 weeks during the COVID-19 pandemic. Only urgent treatment of dental diseases can be performed during the COVID-19 outbreak taking into consideration pharmacological management as the first line and contagion-reduced minimally invasive emergency treatment as the secondary and final management. Conclusions While the currently available evidence has not demonstrated a clear and direct relationship between dental treatment or surgery and the possibility of the transmission of COVID-19, there is clearly the potential for transmission. Therefore, following the protective protocols in the COVID-19 crisis is of utmost importance in a dental setting.

Abstract
Background: Overdose deaths from fentanyl and its analogs have increased significantly since 2013. There are limited data regarding the prevalence of fentanyl exposure among emergency department (ED) patients with active opioid use.Methods: We conducted a cross-sectional study at an urban hospital from May 20 to July 30, 2018. A convenience sample of adult ED patients with active opioid use, defined as opioid use within seven days prior to ED visit, were enrolled. Rapid Response® Single Drug Test Strip (BTNX Inc., Markham, Canada) was used to detect fentanyl in urine samples. Information on demographic, substance use history, and knowledge of fentanyl was obtained using a brief survey tool. Our primary outcome was the prevalence of fentanyl exposure; secondary outcomes included patients' knowledge regarding potency, risk of overdose death from fentanyl and intentional purchase of fentanyl.Results: During our study period, 451 patients reported active substance use. Of these, 208 reported active opioid use and 165 consented for the study. The median age was 49 years [interquartile range: 38, 57] and 77.0% (n = 127) were male; 42 participants (25.5%) presented to ED after an acute overdose event. Heroin was the preferred opioid of use in 90.8% of the participants, primarily via intranasal route (64.6%). Polysubstance use was reported in 98.8%, most commonly with cocaine (57.6%; n = 95). Fentanyl was detected in 104 out of 129 urine samples tested (80.6%). 84.2% (n = 139) identified fentanyl as highly potent and 85.5% (n = 141) recognized highest risk of death in fentanyl overdose. A larger proportion of non-overdose participants intentionally purchased fentanyl (34.1%; n = 42) compared to the overdose group (16.7%, n = 7; p = .04).Conclusions: The majority of ED patient with active opiate use were exposed to fentanyl while one in three participants intentionally purchased fentanyl despite their awareness of its potency and the high-risk of death from overdose.

Abstract
BACKGROUND In an emergency department (ED), intravenous (IV) access is frequently accomplished by inspection and palpation of peripheral veins. Failure of these methods indicates severe IV access difficulty and necessitates advanced techniques. Here, we estimate the incidence of advanced IV access in 2 urban EDs with varying resident coverage. METHODS In this multiple-cohort study, we enrolled data from 2 neighboring urban EDs-a tertiary care ED and a community hospital affiliate. The 2 have similar volumes but the tertiary care ED has more resident coverage (112 vs 20 hours/d). In a prospective data collection (April 2012-2013), we enrolled consecutive patients during hours of scheduled shifts for research assistants. In a retrospective data collection (March 2011-2012), we reviewed charts of a random sample of patients from each ED for similar outcomes. We calculated the incidence of advanced IV access by dividing the number requiring advanced techniques by the number requiring IV access. RESULTS We determined IV outcomes for 790 patients in the prospective cohort and 669 patients in the retrospective cohort. Between groups, there was no difference in the incidence of advanced IV access in the prospective collection (P = .08) or in the retrospective collection (P = .7). Pooling data from both cohorts and both hospitals, the overall incidence was 3.2 [95% confidence interval, 1.9-5.2] per 100 attempts. CONCLUSION Advanced IV access is needed in 3.2% of IV attempts in 2 urban EDs with varying levels of resident coverage. We found similar incidence in both EDs.

Abstract
The aim of this study was to compare the bond strengths of three self-etching materials during one year of storage. Clearfil SE Bond (SE), Clearfil Protect Bond (PB), and Clearfil Tri-S Bond (TS) were used for bonding to dentin and enamel according to manufacturer's instructions. Microshear bond strength values were measured after 24 hours, six months, and one year. Two-way ANOVA showed that the interaction of material type and storage time was significant for dentin. At baseline, SE had the highest bond strength to dentin. There were no significant changes in bond strength for each material during the storage period, except for PB which showed increased bond strength to dentin after one year. All materials performed reliably after one year. However, the antibacterial and fluoride-releasing effects of PB would further contribute to the long-term clinical benefits of this material.
