The Right to Education and ICT during COVID-19: An International Perspective

2020

There is a lack of concluding evidence among epidemiologists and public health specialists about how school closures reduce the spread of COVID-19. Herein, we attend to the generalization of this action throughout the world, specifically in its quest to reduce mortality and avoid infections. Considering the impact on the right to education from a global perspective, this article discusses how COVID-19 has exacerbated inequalities and pre-existing problems in education systems around the world. Therefore, the institutional responses to guaranteeing remote continuity of the teaching&ndash

Quality of YouTube TM videos on dental implants

2018

Background Patients search YouTube for health-care information. Purpose To examine what YouTube offers patients seeking information on dental implants, and to evaluate the quality of provided information. Material and Methods A systematic search of YouTube for videos containing information on dental implants was performed using the key words “Dental implant” and “Tooth replacement”. Videos were examined by two senior Oral and Maxillofacial Surgery residents who were trained and calibrated to perform the search. Initial assessment was performed to exclude non- English language videos, duplicate videos, conference lectures, and irrelevant videos. Included videos were analyzed with regard to d…

Methotrexate-Loaded Polymethylmethacrylate Bone Cement for Local Bone Metastasis Therapy: Pilot Animal Study in the Rabbit Patellar Groove

2008

Local chemotherapy is an option in bone metastasis treatment. On the other hand, evaluation of side effects on bone is a difficult issue in drug development and biomaterials research. Most animal models to date are inappropriate or not feasible. Rabbits are an alternative to other bigger mammals and have an appropriate bone structure compared to rats and mice. The patellar groove model of the rabbit offers a standardized and sensitive model to evaluate bone-compromising drug effects. We tested the system with a reproducible polymethacrylate implant as carrier and loaded this system with methotrexate. Three methotrexate concentrations were used in the test samples (250 mg, 1 g and 4 g per 40…

Bisphosphonate treatment and dental implants: A systematic review

2015

Background To analyze articles that studied patients submitted to diphosphonates therapy and who received dental implants before, during or after bisphosphonate (BP) treatment, compared to healthy patients, analyzing the increase of failure and loss of implants or bisphosphonate related osteonecrosis of the jaw (BRONJ) incidence. Material and Methods The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement was used in this study. The clinical question in “PICO” format was: In patients under bisphosphonate therapy, do dental implants placement, compared to healthy patients, increase the failure and loss of implants or bisphosphonate related osteonecrosis of t…

Dental implants in patients treated with oral bisphosphonates. A bibliographic review

2010

Bisphosphonates inhibit bone resorption and are used to treat a range of pathologies, including Paget disease, osteoporosis, multiple myeloma and metastases associated with breast or prostate cancer. At present, there is no effective treatment for bisphosphonate induced osteonecrosis, so prevention is extremely important. Since quality of life deteriorates for those suffering osteonecrosis, maximum precautions should be taken with patients at risk, and especially whenever oral surgery, including dental implant placement, is contemplated. Dentists and oral or maxillofacial surgeons must keep up to date with the latest approaches to prevention, particularly when treating patients who are pres…

Assessment of clinical outcomes and histomorphometric findings in alveolar ridge augmentation procedures with allogeneic bone block grafts: A systema…

2020

Background This systematic literature review aimed to evaluate the efficacy of allogeneic bone blocks for ridge augmentation by assessing block survival rates and subsequent implant survival, including post-surgical complications and histomorphometric analysis. Material and Methods An electronic and manual search among references, was conducted up to April 2019 by two independent authors. Inclusion criteria were: human clinical trials in which the outcomes of allogeneic bone block grafts were evaluated by means of their survival rates and subsequent implant success rates. Results Seven articles fulfilled the inclusion criteria and were analyzed. A total of 323 allogeneic block grafts were m…

Preemptive analgesia in dental implant surgery: A systematic review and meta-analysis of randomized controlled trials

2021

Background To assess the effectiveness of preemptive analgesia in dental implant surgery in randomized controlled trials (RCTs). Material and Methods The present study was conducted in accordance with the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and registered in PROSPERO database CRD42020168757. A search without restrictions regarding language or date of publication was conducted in six databases and gray literature. A random effect meta-analysis compared the efficacy of preemptive analgesia compared to placebo through pooled OR and 95%CI. The interpretation of results followed the certainty of evidence using the Grading of Rec…

A Real-World Study of Dexamethasone Implant in Treatment-Naïve Patients with Diabetic Macular Edema: Efficacy and Correlation Between Inflammatory Bi…

2020

Purpose There has been an increasing clinical interest in specific retinal parameters as non-invasive biomarkers of retinal inflammation in diabetic macular edema (DME) that have been shown to have prognostic value, such as hyperreflective retinal fields (HRFs) and subfoveal neuroretinal detachment (SND). Methods We conducted a prospective, non-comparative study of treatment-naive patients with DME to evaluate the efficacy of a Pro Re Nata (PRN) regimen of intravitreal dexamethasone implant 0.7 mg (DexI, Ozurdex™). After administration, patients underwent subsequent injections according to PRN criteria in case of edema relapse, but not earlier than 4 months after the previous treatment. Pat…

Alveolar distraction osteogenesis for dental implant treatments of the vertical bone atrophy : a systematic review

2019

Background To determine if alveolar vertical distraction osteogenesis obtains better results compared to other bone regeneration treatments (guided bone regeneration with membranes and / or filling material, or autogenous bone graft) in terms of bone gain, complications, and implant survival and success rates. Material and Methods An electronic search was performed in Pubmed (MEDLINE), Cochrane Library and Scopus databases in March 2017. Besides, a manual search was carried out. Inclusion criteria were randomized controlled trials published within the last 10 years with at least 1 year of follow-up after implant placement. No language restriction was applied. Exclusion criteria were studies…
