A Novel Framework for Melanoma Lesion Segmentation Using Multiparallel Depthwise Separable and Dilated Convolutions with Swish Activations.

Skin cancer remains one of the deadliest kinds of cancer, with a survival rate of about 18-20%. Early diagnosis and segmentation of the most lethal kind of cancer, melanoma, is a challenging and critical task. To diagnose medicinal conditions of melanoma lesions, different researchers proposed automatic and traditional approaches to accurately segment the lesions.

Determinants of COVID-19 Vaccine Acceptance among Dental Professionals: A Multi-Country Survey.

Purpose: This study sought to investigate the acceptance rate and associated factors of COVID-19 vaccines among dentists and dental students in seven countries.

Material And Methods: A structured questionnaire prepared and guided by the report of the SAGE Working Group on Vaccine Hesitancy was distributed among groups of dentists and dental students in seven countries across four continents.

Results: A total of 1527 subjects (850 dentists and 677 dental students) participated in this survey.

A Global Survey of COVID-19 Vaccine Acceptance Among Healthcare Workers.

Objectives: Even though several effective vaccines are available to combat the COVID-19 pandemic, wide disparities in vaccine distribution, and vaccine acceptance rates between high- and low-income countries appear to be major threats toward achieving population immunity. Our global descriptive study aims to inform policymakers on factors affecting COVID-19 vaccine acceptance among healthcare workers (HCWs) in 12 countries, based on income index. We also looked for possible predictors of vaccine acceptance among the study sample.

Association of dietary calcium, magnesium, and vitamin D with type 2 diabetes among US adults: National health and nutrition examination survey 2007-2014-A cross-sectional study.

Higher dietary intake of calcium (Ca), magnesium (Mg), and vitamin D has been associated with reduced risk of type 2 diabetes (T2DM), and a higher intracellular ratio of Ca to Mg leads to insulin resistance. Previous epidemiological studies did not examine the combined effects of dietary Ca, Mg, and vitamin D as well as ratio of Ca to Mg with T2DM. Therefore, we assessed the relationship between dietary intakes of Mg, Ca, and vitamin D (using 24-hr recalls) individually and in composite and T2DM in the National Health and Nutrition Examination Survey 2007-2014, which involved 20,480 adults (9,977 men and 10,503 women) with comprehensive information on related nutrients, and anthropometric, demographic, and biomarker variables using multivariable logistic regression.

The knowledge about coronavirus (COVID-19) among populations in two different Arab countries.

Unlabelled: COVID-19 is an infectious disease caused by a newly discovered coronavirus. Most patients infected with the COVID-19 virus experience mild to moderate respiratory symptoms and heal without any special treatment. This survey aimed to assess the knowledge of Syrian and Saudi populations about the general information, symptoms, and methods of prevention of coronavirus (COVID-19).

Root canal morphology of mandibular canines in the Syrian population: A CBCT Assessment.

Introduction: The recent study aimed to assess the root canal morphology of mandibular canines in the Syrian population depending on the cone beam computed tomography (CBCT) images.

Materials And Methods: A total of 418 fully developed mandibular canines in Syrian individuals aged between 16 and 60 years were included. The presence of at least one mandibular right or left canine with fully developed roots was recorded in each image.

Root canal treatment of mandibular canine with two root canals: A case report series.

Canine is the cornerstone of the mouth due to its position, which reflects its significance of mastication with incisors and premolars. Anomalous root canal morphology can be found in any tooth with different degrees. The unusual configuration of root canal system may lead to a lot of procedural errors during cleaning and shaping, and this, in turn, may increase the probability of root canal treatment failure.

Dentists' Knowledge, Attitude and Practice of Root Canal Treatment Procedure: Survey-based Research.

Aim: The aim of this survey was to assess the dentists' knowledge, attitude and practice of endodontic treatment procedures and materials in Damascus city (capital of Syria), and the effect of endodontic specialty and years of experience on the survey findings.

Materials And Methods: Two hundred direct contacts (25 multiple-choice questions containing) questionnaires were distributed to randomly selected dentists practicing in Damascus city in 11 different areas, and a questionnaire contained questions regarding dentists' knowledge, attitude, and practice of root canal treatment procedure. The collected data were entered into a personal computer and analyzed using the statistical package for the social sciences (SPSS), 25 edition.

Evaluation of the Apical Seal of Mineral Trioxide Aggregate in the Absence and Presence of Smear Layer.

Aim: The aim of this study was to evaluate the apical sealability of mineral trioxide aggregate (MTA) when used as an orthograde root filling material, and to evaluate whether smear layer removal has any influence on the apical seal of this material.

Materials And Methods: Forty single-rooted human mandibular premolars were selected in this study. The selected teeth were randomly divided into two equal groups (n = 20) based on the irrigation type.

Modalities of using endodontic nickel-titanium rotary instruments and factors influencing their implementation in dental practice.

Background: To establish the extent of using nickel titanium rotary instruments (NiTi-RIs), to identify reasons for using / not using NiTi-RIs, to explore usage modalities and to identify factors and measures that can increase implementation of NiTi-RIs in general dental practice.

Methods: Two pilot questionnaires were conducted on academic staff members at College of Dentistry, Taibah University, general dentists (GDs) and endodontists to finalise the questionnaire. A sample size was calculated considering the expected and minimum accepted response rates (60 and 48%, respectively) and a 99.

Radiographic Assessment of the Quality of Root Canal Fillings Performed by Senior Dental Students.

Objective: To evaluate the radiographic technical quality of root canal fillings performed by senior dental students at Alfarabi colleges for dentistry, Kingdom of Saudi Arabia.

Methods: Radiographic assessment was conducted for 246 teeth (390 root canals) endodontically treated by senior dental students to evaluate the quality of root canal fillings. Three criteria were evaluated to assess the technical quality of root canal fillings: length, density, and taper.

Radiographic Assessment of the Prevalence of Pulp Stones in a Yemeni Population Sample.

Objective: To determine the prevalence and distribution of pulp stones in the posterior teeth of a sample of adult Yemeni dental patients using digital panoramic radiographs.

Methods: In total, 913 panoramic radiographs from patients attending the hospital dental clinics of at University of Sciences and Technology, Sana'a, Yemen, from January 2013 to December 2014 were examined. The occurrence of pulp stones in the posterior teeth of adult subjects was recorded.
