The burden of cardiovascular disease in Latin America and the Caribbean, 1990-2019: An analysis of the global burden of disease study.

Introduction: Cardiovascular disease (CVD) remains the leading cause of death globally, including the Latin America and the Caribbean (LAC) region. However, limited research has been conducted on the burden of CVD in this region. Our study aims to investigate the burden of CVD and related risk factors (RFs) in the LAC.

Molar root canal treatment performed by undergraduate dental students; an observational study of procedural errors and student perception.

Background: Molar root canal treatment (RCT) is challenging and requires training and specific skills. Rotary instrumentation (RI) reduces the time needed for instrumentation but may increase the risk of certain procedural errors. The aims of this study were to evaluate the quality of molar RCTs provided by undergraduate students, to compare the prevalence of procedural errors following manual and RI, and to assess the students' self-perceived confidence to perform molar RCT without supervision and their preference for either manual or RI.

Deep Margin Elevation - A Retrospective Clinical Study.

Purpose: The aim of this retrospective study was to assess the short- to mid-term restorative and periodontal outcome of deep margin elevation (DME) performed using resin composite.

Materials And Methods: Twenty-eight teeth treated with DME and indirect adhesive restorations were followed-up for a mean of 25.4 months (minimum: 12 months).

Endocrowns Clinical Performance and Patient Satisfaction: A Randomized Clinical Trial of Three Monolithic Ceramic Restorations.

Purpose: The purpose of this randomized, double-blind, clinical trial was to assess the survival of endocrowns made from three different monolithic ceramic materials, and to evaluate patient satisfaction.

Materials And Methods: Fifty-three patients (sixty root canal treated molar teeth) were enrolled. Teeth were prepared to a flat butt-joint margin and randomly divided between three material groups: lithium disilicate-reinforced glass-ceramic, monolithic zirconia and polymer infiltrated hybrid ceramic.

Effect of freshly placed core buildup composites on setting of silicon impression materials.

Aim: The aim is to study the effect of freshly placed composite build-ups on setting of additional silicone impression materials.

Settings And Design: In vitro - experimental study.

Materials And Methods: Three composite materials; Build-It™ F.

Impact of COVID-19 pandemic on dental education: online experience and practice expectations among dental students at the University of Jordan.

Background: The quarantine associated with the COVID-19 pandemic forced dental schools to suspend their clinical training and to shift to distant learning methods. The aim of this study is to investigate the impact of quarantine on the self-perceived preparedness of dental graduates and to explore the efficacy of online education from students' perspectives.

Methods: The questionnaire distributed to dental students comprised of two main sections.

Prevalence and Configuration of the Second Mesiobuccal Canal in the Permanent Maxillary First Molar in Jordanian Population Sample.

Introduction: Missing a root canal during endodontic treatment implicates the persistence of microbial infection within the root canal system. This study aims to evaluate the incidence and morphology of the second mesiobuccal canal in the maxillary first molars in the Jordanian population.

Methods And Materials: Consecutive cone-beam computed tomography (CBCT) scans taken at Jordan University Hospital were assessed in this retrospective study.

Awareness of the risk of developing medication-related osteonecrosis of the jaw among bisphosphonate users.

Objective: In this retrospective observational study, we evaluated awareness among patients using bisphosphonates (BPs) regarding the risk of developing medication-related osteonecrosis of the jaw (MRONJ) and whether they received appropriate dental screening and treatment prior to commencing medication.

Methods: Patients using BPs who attended the endodontics clinic at Jordan University Hospital in 2019 were interviewed using a pre-designed questionnaire. Data were analysed using descriptive statistics and chi-squared tests.

Diagnostic delay and suboptimal management in persistent idiopathic facial pain and persistent dentoalveolar pain; a cross-sectional study.

Objectives: The aim of this study was to explore the diagnostic and therapeutic challenges encountered by patients with persistent idiopathic facial pain (PIFP) and to investigate factors influencing its delayed diagnosis.

Study Design: In this cross-sectional study, 34 patients with newly diagnosed PIFP were interviewed. Data about diagnostic delay, number and nature of previous consultations, and previous medical and surgical interventions were recorded.

Satisfaction of undergraduate students at University of Jordan after root canal treatment of posterior teeth using rotary or hand preparation.

The aim of this study was to report the satisfaction of fifth year undergraduate students on the clinical use of rotary endodontic preparation compared with stainless steel standard technique and to evaluate the impact of rotary nickel-titanium instruments on undergraduate teaching. This study was carried out by the fifth year undergraduate students attending peer review sessions as a part of their training program using a questionnaire to assess their satisfaction with these two techniques. The overall results indicated a statistically significant satisfaction of the undergraduate students with the use of the nickel-titanium system (P < 0.

The effect of smear layer on the push-out bond strength of root canal calcium silicate cements.

Introduction: The aim of this study was to evaluate the effect of smear layer removal on the push-out bond strength between radicular dentin and three calcium silicate cements (CSC) in comparison with gutta percha and sealer.

Methods: Eighty human anterior extracted teeth were decoronated, cleaned and shaped to size 50/0.05 apically and randomly divided into 2 major groups: (A) smear layer preserved, and (B) smear layer removed using irrigation with 17% EDTA.

Resistance to vertical fracture of MTA-filled roots.

Aim: To investigate the effect of MTA root canal fillings on the resistance to vertical root fracture (VRF) over different time intervals.

Material And Methods: Freshly extracted anterior human teeth with single canals and minimal curvatures were decoronated, instrumented to size 50/.05 ProTaper file, irrigated with 1%NaOCl and randomly allocated to one of three groups (n = 36): (i) filled with MTA, (ii) filled with gutta-percha and sealer and (iii) unfilled roots used as a negative control.

A micro-computed tomography evaluation of mineral trioxide aggregate root canal fillings.

Introduction: The aim of this study was to assess the effect of indirect ultrasonic activation on the incidence of voids within mineral trioxide aggregate (MTA) root canal fillings and at their interface with the canal walls by using a nondestructive 3-dimensional (3D) micro-computed tomography (micro-CT) analysis.

Methods: Extracted human teeth with single canals and minimal curvatures were decoronated, instrumented to size 50/05 apically, and randomly allocated into 4 groups (n = 12). MTA was compacted manually by using hand pluggers in group A (MC).
