Evidence Mapping and Quality Assessment of Systematic Reviews in Dental Traumatology: A 54 Months Update.

Background/aims: This update of previously conducted evidence mapping and quality analysis of systematic reviews related to dental traumatology aimed to assess the distribution of systematic reviews published in a period of past 54 months in various domains and subdomains and evaluate their quality. An attempt was also made to compare the trends of methodological and quality characteristics between the two Evidence Mapping studies.

Methods: An a priori protocol was prepared as per the recommendations of Global Evidence Mapping and registered in Open Science Framework.

Comparative Effectiveness of Regenerative Endodontic Treatment Versus Apexification for Necrotic Immature Permanent Teeth With or Without Apical Periodontitis: An Umbrella Review.

Background/aim: The evidence related to the superiority of the recommended treatment protocols for necrotic immature permanent teeth is unclear. We aimed to compare the clinical, radiographic, and overall success rates of apexification and regenerative endodontic treatment (RET), assess the methodological quality, and assess the strength of evidence for outcomes.

Methods: A search was performed in PubMed, Scopus, LILACS, EMBASE, Web of Science, and the Cochrane Library.

An Study to Compare the Shear Bond Strength of Metal and Ceramic Brackets Using Conventional Acid Etch and Self-Etch Primer.

Aim: In this, study's objective is to assess the shear bond strength (SBS) of metal and ceramic orthodontic brackets that have been adhered to enamel using a conventional acid etch/primer and self-etching primer (SEP) adhesive method.

Materials And Methods: One hundred excised human premolars were bonded on brackets and were divided into group 1 -Metal brackets were bonded on teeth and group 2 -Ceramic brackets were bonded on teeth. These two groups were further subdivided: subgroup 1a - 25 metal brackets bonded using conventional acid etch/primer adhesive system, subgroup 1b - 25 metal brackets bonded using SEP, subgroup 2a - 25 ceramic brackets bonded using conventional acid etch/primer adhesive system, and subgroup 2b - 25 ceramic brackets bonded using SEP; brackets were debonded using a computerized Instron universal testing machine.

A Case Report on Internal Hernia as an Unusual Cause of Small Bowel Obstruction: A Diagnostic Triumph Unveiled by Computed Tomography Scan.

Paraduodenal hernia is a type of internal hernia caused by defects in the peritoneum during fetal development. It is one of the uncommon causes of intestinal obstruction; diagnosing it and intervening promptly are required. In this case report, we describe our experience treating an adult male patient who presented with symptoms of acute small bowel obstruction and was later diagnosed with internal hernia on further evaluation.

COVID-19 infection, and reinfection, and vaccine effectiveness against symptomatic infection among health care workers in the setting of omicron variant transmission in New Delhi, India.

Background: Surge of SARS CoV-2 infections ascribed to omicron variant began in December 2021 in New Delhi. We determined the infection and reinfection density in a cohort of health care workers (HCWs) along with vaccine effectiveness (VE) against symptomatic infection within omicron transmission period (considered from December 01, 2021 to February 25, 2022.

Methods: This is an observational study from the All India Institute of Medical Sciences, New Delhi.
