It was observed that the participants were unsatisfactorily cautious against the COVID-19 infection and its dissemination pathways in their social environment, particularly in the specific case of systematic diseases and preventive measures. The primary way of obtaining information about the COVID-19 infection was the electronic websites.<br /><br /> Deplorably, accentuating the urgent need for further intensive training programs on the relationship between the systemic diseases and COVID-19 infection, and explicit daily care methods in the social environment.<br /><br />Deplorably, accentuating the urgent need for further intensive training programs on the relationship between the systemic diseases and COVID-19 infection, and explicit daily care methods in the social environment.<br /><br /> The Saudi Ministry of Health (MOH) has published detailed guidelines and educational documents about Coronavirus disease 2019 (COVID-19) prevention and infection control. The knowledge of dentists of the reported guidelines is not yet assessed and lack of awareness of these guidelines may have negative implications on dental patients.<br /><br /> The aim of this study is to assess the knowledge of dentists about COVID-19 and the MOH guidelines while treating dental patients in Saudi Arabia.<br /><br /> A cross-sectional study was conducted using an online survey which was sent to a sample of dentists in Saudi Arabia from March to May 2020.<br /><br /> A total of 294 dentists with a mean age of (36.9 ± 10.6) years completed the questionnaire. Participants included 157 females and 137 males with a range of professional classification and experience. All of the participants were aware of COVID-19, the nature of the disease, symptoms, modes of transmission and people at higher risk, except for 7.2% who did not report the correct incubation period. All participants agreed that patients and staff should wear a facial mask, use hydroalcoholic hand sanitizer upon arrival. Only 72.4% had knowledge about published guidelines. Infection control training was provided for 53% of the participants and those who had training were more confident to treat patients. Regarding personal protective equipment (PPE), putting on and taking off PPE, 64.6% and 78.6%, respectively, were aware of the guidelines.<br /><br /> Dentists in Saudi Arabia had optimal knowledge about COVID-19. However, infection control training is recommended to increase readiness and confidence among dentists.<br /><br />Dentists in Saudi Arabia had optimal knowledge about COVID-19. However, infection control training is recommended to increase readiness and confidence among dentists.<br /><br /> Widening the breadth of dentists' responsibilities to include screening all patients for life-threatening diseases, such as head and neck cancer (HNC), is crucial to improve survival rates and decrease morbidity.<br /><br /> The study aimed to assess the knowledge and behavior of dentists toward screening and managing patients with HNC in Daudi Arabia. Thus, this study aimed to assess the knowledge and behavior of dentists toward screening and managing patients with HNC in Saudi Arabia.<br /><br /> This cross-sectional study comprised a closed-ended electronic questionnaire sent to dentists including general practitioners, specialists, and consultants (n = 723). The e-questionnaire included questions that assessed dentists' behavior and knowledge toward screening and managing patients with HNC. The Chi-square test was used to establish relationships between categorical variables.<br /><br /> The response rate was 28.5%. Dentists obtained the dental and medical histories of 74% and 80% of their cases, respectively. Only 55% and 14% of deaced on updating information on clinical practices and having dentists familiarize themselves with HNC screening methods and tools. Ultimately, the role of the dentist should include screening and detecting systemic diseases in dental settings.<br /><br /> It is important to inform nursing students about stroke and improve their role in the clinic.<br /><br /> We aimed to assess the awareness/knowledge of stroke risk factors and warning signs among nursing students. Therefore, we aimed to assess the awareness/knowledge of stroke risk factors and warning signs among nursing students.<br /><br /> The descriptive and cross-sectional study was carried out between December 2017 and March 2018 with intern students at the faculty of nursing of a university. The sample consisted of 173 students. The data were collected by researchers using "Student Information Form" and "Information Form about Stroke". The ethical and institutional permission were obtained to conduct the research.<br /><br /> Hypertension (96.5%) for risk factors, weakness (98.8%) for warning signs, blood pressure control (96.5%) for prevention measures were the most commonly identified factors. [https://www.selleckchem.com/products/phycocyanobilin.html Phycocyanobilin] Approximately half of the students had a good level of awareness/knowledge of risk factors (53.2%) and warning signs (53.8%) for stroke. The majority of students (84.4%) had a good level of awareness/knowledge of prevention measures. Ninety-five percent of the students stated that calling an ambulance would be the first appropriate action.<br /><br /> Students had a good knowledge of some of the warning signs and risk factors about stroke. Therefore, it is recommended that this subject should be emphasized more in course contents.<br /><br />Students had a good knowledge of some of the warning signs and risk factors about stroke.

A thematic analysis approach was applied to the transcribed qualitative data.<br /><br /> Midwives rarely provide physical activity education and counseling to pregnant women, citing lack of knowledge on which physical activity to recommend, and the duration and intensity of the physical activity as reasons. Walking is the only physical activity recommended during antenatal sessions. Barriers to providing physical activity education and counseling include shortage of midwives, busy work responsibilities, nonavailability of exercise equipment, and nonprioritization of antenatal physical activity. The midwives also cited overwhelming work reworkshops on maternal physical activity. Our findings suggest that physical activity should be integrated into the midwifery/nursing curriculum to empower midwives and other health providers to offer evidence-based physical activity education and counseling to women during antenatal health care as part of the primary health-care service.<br /><br /> To compare the effects of platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) on oral health-related quality of life (OHQoL) following impacted mandibular third molar (M3) surgery.<br /><br /> A prospective, randomized study of 50 subjects was designed. Participants were divided equally into the PRP and PRF groups. The OHQoL was assessed using the OHQoL-UK instrument preoperatively and on postoperative days (PODS) 1, 3, and 7. Categorical variables were presented as frequencies and proportions. The linear mixed model analysis was used to determine the effects of PRF and PRP on overall OHQoL with respect to time, treatment, and treatment by time-point interaction. The analysis was also performed for the physical, social, and psychological domains.<br /><br /> Fifty subjects were analyzed. The time-point assessment of the overall OHQoL was significant within the PRP and PRF groups (P-values of 0.01 and 0.000002, respectively). The time-point analysis was also significant in both study groups at all domain levels (P &lt; 0.05). A comparison of treatment by time-point interaction for the overall OHQoL between the study groups was insignificant (P = 0.217). Treatment by time-point interaction for OHQoL between the study groups at social and psychological domain levels was insignificant, however, at the physical domain level, PRF had a significantly better effect on OHQoL (P = 0.016).<br /><br /> The study showed that the overall OHQoL was not significantly different between the PRP and PRF groups after M3 surgery. However, PRF had a significant influence on OHQoL at the physical domain level.<br /><br />The study showed that the overall OHQoL was not significantly different between the PRP and PRF groups after M3 surgery.

Computer-aided design and manufacturing (CAD-CAM) in full and Lava Ultimate restorative materials were chosen. The 3 × 3 mm<br /><br /> standardized, 0.5-mm and 1 mm thick specimens were cemented on an enamel surface. After thermocycling, each material group was randomly divided into laser treated and control (non-laser treated) groups. Shear bond strength test was done with a universal testing machine with crosshead speed 0.5 mm/min. Factorial ANOVA Technique and TUKEY HSD multiple comparison test were used for statistical analyses. Moreover, the surface morphology of the debonded samples and the enamel was observed using a scanning electron microscope.<br /><br /> The laser application was found to weaken the SBS values significantly (P &lt; 0.05) for all groups; however, the most dramatic SBS decrease was observed for laser treated IPS e.max at both thicknesses.<br /><br /> Laser treatment can serve as a practical and effective method that eliminates the risk the enamel damage and restoration fracture.<br /><br />Laser treatment can serve as a practical and effective method that eliminates the risk the enamel damage and restoration fracture.<br /><br /> This cross-sectional observational retrospective study aimed at assessing the cephalometric skeleto-dental features of class I, II, and III skeletal relationships of Saudi female school children samples and comparing the results to the established North American Caucasian cephalometric standards.<br /><br /> The sample consisted of 205 retrospective lateral cephalometric radiographs of female school children. The age range of the subjects was between 10 and 13 years with a mean age of 11 ± 1 years. Several cephalometric and constructed points were identified. Angular, linear, and proportional measurements were obtained and analyzed. The skeleto-dental features of class II and class III were compared to class I of this sample then compared with the established North American Caucasian population. Different angular, linear, and proportional variables were investigated. Descriptive statistics and student t-test were used for data analysis.<br /><br /> The distribution of the skeletal relationship revealed that 68.3% of the sample as a base-line for future investigations in Saudi Arabia.<br /><br /> Helicobacter pylori (H. pylori) is a common bacteria all over the world. The factors influencing the acquisition and prevalence of H. pylori infection are still poorly understood.<br /><br /> The aim of this study was to determine the factors that may affect H. pylori positivity in patients who presented to the pediatric clinic.<br /><br /> The study included 374 children who attended the pediatric clinic with gastrointestinal complaints. The demographic characteristics of patients were recorded, and fecal samples were examined for H. pylori positivity with a prepared kit procedure. In addition, the samples were examined under microscope for the diagnosis of parasites in stool. The Chi-square analysis and binary logistic regression analysis were used for data analysis. The odds ratio was calculated as an estimate of the relative risk. Results The study found the incidence of H. pylori positivity to be 18.7%. It was observed that in all H. pylori positive patients had growth retardation. H. pylori positivity had no significant relationship with the presence of parasites in the stool (p = 0.
