Fluorescent Marker as a Tool to Improve Strategies to Control Contaminated Surfaces and Decrease Danger of Cross-Contamination in Dental Clinics, during and beyond the COVID-19 Pandemic.

The COVID-19 pandemic posed an increased threat to dental personnel and patients. Close encounters with patients' breath and saliva and the use of intraoral rotating instruments which disperse microscopic airborne particles both increase the possibility of environmental infection. In this study, fluorescent marker (FM) was used to assess and enhance surface cleanliness in the dental clinics and public areas of a major dental school.

Rethinking the Current "Stage-and-Wait" Paradigm.

Introduction: The experience of terrorist incidents involving a secondary explosive device that targeted rescue forces led to changes in the safety protocols of these forces in most countries of the world. These protocols are the foundation of the current "Stage-and-Wait" paradigm that prohibits the entry of Emergency Medical Services (EMS) from entering the scene and treating casualties until it is deemed safe. These guidelines were established absent of an evidence-base detailing the risk to responders and the potential consequences to the injured on-scene.

Effect of Silica-Modified Aluminum Oxide Abrasion on Adhesion to Dentin, Using Total-Etch and Self-Etch Systems.

This study compared the shear bond strength (SBS) and micromorphology of composite resin to human dentin after pre-treatment with silica-modified aluminum oxide air abrasion. Forty-six molar teeth were treated with either Scotchbond Multi-Purpose (SCMP) or Clearfil SE Bond (CLSE) adhesive. Buccal surfaces were pre-treated with the CoJet air abrasion system (SB), and lingual surfaces were controls.

Sleep-Related Breathing Disorders in Children-Red Flags in Pediatric Care.

Objectives: In recent years, we have witnessed a growing interest in pediatric sleep-related breathing disorders (SRBD). Although a Pediatric Sleep Questionnaire (PSQ) exists and was found reliable in screening SRBD in children, many of the children remain underdiagnosed. The aim of the present study was to define anamnestic and clinical findings that can serve as red flags indicating the presence of SRBD in children.

Possible Association between Methylphenidate and Mandibular Bone Characteristics Detected by Dental Panoramic Radiograph in Children and Adolescents with ADHD.

Some studies have shown that children treated with psychostimulants for attention-deficit hyperactivity disorder (ADHD) have decreased bone mineral density (BMD). Mandibular cortical width (MCW) may be used as a surrogate measure for evaluating BMD. We compared the MCW measured on digital panoramic radiographs (DPR) of 38 children and adolescents with ADHD who were treated with methylphenidate for at least 12 months to the MCW of 58 children and adolescents without ADHD (control).

Effect of Denture Base Fabrication Technique on Adhesion In Vitro.

Denture stomatitis is a common manifestation of oral candidiasis affecting some 65% of denture wearers. This condition is initiated by the adherence of to denture base acrylic resin. The present study aimed to test the in vitro effect of traditional and novel fabrication methods on adhesion to denture base samples.

[HOW HEALTH SERVICES IN ISRAEL COPED WITH THE POLIO EPIDEMIC OF THE 1950'S].

Today, the introduction of a new medicine or vaccine or the clinical trial of some new potion requires the approval of a variety of bodies in accordance with Helsinki Agreement rules, National Health Laws and Health Ministry regulations. The creation of the World Health Organization (WHO) in 1946 added another essential layer to the firm base of principles governing the conduct of clinical trials that exist today. Its main contribution was to create a new reality following The Second World War and the subsequent Nuremberg Trials.

An in vitro evaluation of marginal fit zirconia crowns fabricated by a CAD-CAM dental laboratory and a milling center.

Background: Marginal fit is critical for the success and longevity of a dental restoration. Zirconia crowns can be fabricated either chair-side, in a dental laboratory or in a milling center; each can give different marginal fits results. However, discussion of the marginal fit of zirconia crowns when different fabrication methods are compared is lacking in the literature.

Combined reconstruction of the medial patellofemoral and medial patellotibial ligaments: outcomes and prognostic factors.

Purpose: To report outcomes after combined medial patellofemoral ligament (MPFL) and medial patellotibial ligament (MPTL) reconstruction and test associations between prognostic factors and clinical outcomes. It was hypothesised that combined MPFL and MPTL reconstruction would result in significant improvement in function, and that outcomes would be associated with age, sex, Beighton score, concomitant articular lesions, and preoperative function.

Methods: All combined reconstructions of MPFL and MPTL were reviewed.

Comparison of marginal fit between CAD-CAM and hot-press lithium disilicate crowns.

Statement Of Problem: Hot-pressing and computer-aided design and computer-aided manufacturing (CAD-CAM) are major techniques for the fabrication of lithium disilicate crowns. They exhibit different accuracies regarding marginal fit, an important factor in restoration survival. However, studies comparing the marginal fit of different fabrication methods are lacking.

Interpretations of complications following third molar extraction.

Objective: Surgical removal of third molars is often associated with complications. The aim of the present study was to analyze the incidence of complications following extraction of third molars relative to the risk factors.

Method And Materials: This retrospective study included 463 patients who had mandibular third molar extraction (performed by a single surgeon, DSA) in the years 2001 to 2011.

Factors Associated With Improved Function and Maintenance of Sports Activities at 5 to 10 Years After Autologous Hamstring ACL Reconstruction in Young Men.

Background: There are limited data regarding associated factors of return to sports activities at more than 5 years after anterior cruciate ligament (ACL) reconstruction.

Purpose: To test interrelationships between patient characteristics, concomitant articular lesions, graft laxity, and maintenance of sports activities at 5 to 10 years after ACL reconstruction. It was hypothesized that at 5 to 10 years after the operation in young adult men, maintenance of greater activity level and better knee function would be associated with greater preinjury activity level, younger age at reconstruction, absence of concomitant articular lesions, and minimal graft laxity at follow-up.

Displaced mid-shaft clavicular fractures: is conservative treatment still preferred?

Background: A clavicular fracture accounts for 2.6%-5% of adult fractures. Fractures in the middle-third (OTA 15-B) represent 69%-82% of all clavicular fractures.

Fluoride ion release and solubility of fluoride enriched interim cements.

Statement Of Problem: Interim and definitive restorations cemented with interim cements for a prolonged interval are susceptible to bacterial infiltration and caries formation.

Purpose: The purpose of this in vitro study was to evaluate the long-term fluoride release and solubility of aged ZnO-based interim cements enriched separately with 0.4% NaF and SnF2.

Olive leaf extract as a hypoglycemic agent in both human diabetic subjects and in rats.

Olive tree (Olea europaea L.) leaves have been widely used in traditional remedies in European and Mediterranean countries as extracts, herbal teas, and powder. They contain several potentially bioactive compounds that may have hypoglycemic properties.

Children and terror casualties receive preference in ICU admissions.

Objective: Trauma casualties caused by terror-related events and children injured as a result of trauma may be given preference in hospital emergency departments (EDs) due to their perceived importance. We investigated whether there are differences in the treatment and hospitalization of terror-related casualties compared to other types of injury events and between children and adults injured in terror-related events.

Methods: Retrospective study of 121 608 trauma patients from the Israel Trauma Registry during the period of October 2000-December 2005.

Arthroscopic rotator cuff repair: clinical outcome of 607 patients.

The purpose of this study was to evaluate the clinical results of rotator cuff tendon tears treated by arthroscopic repair with suture anchors. This prospective study included a cohort of 607 consecutive patients who underwent arthroscopic rotator cuff repair surgery. Most patients had a single-row type of repair using metal anchors.

Anterior knee-pain syndrome.

Anterior knee-pain syndrome would best be defined as a painful condition that arises in or around the patellofemoral joint and is insidious in onset and bilateral, with no macroscopic gross pathology. Anterior knee pain as a descriptive term would define the need to search further for a specific cause of pain, because neither patellar cartilage damage nor malalignment would necessarily be correlated to pain. The examining physician should be aware that specifically in adolescents the higher chance would be that, eventually, no clear-cut pathology would be found; thus, great caution should be taken before diagnosing anterior knee-pain syndrome as existing unilaterally.

[On health, sense and confidentiality].

Medical confidentiality is a cornerstone of doctor-patient relations. Although physicians are obliged to keep to themselves any information concerning their patients, it is understood that this obligation is not absolute. There are extreme situations in which doctors are expected, by law, to break medical confidentiality for the benefit of the public.
