A study of the COVID-19 pandemic's knowledge and impact on ongoing fixed orthodontic treatment in adults.

Background: Due to the characteristics of dental practices and hospitals, all dental professionals, including orthodontists, are at an elevated peril of SARS-CoV-2 infection. If adequate safety actions are not taken, cross-contamination risk among dentists, orthodontists, and patients can be extremely high. For orthodontic patients, a high level of cognizance and consideration of the COVID-19 epidemic is required.

Comparative Assessment of Perceived Pain in Children During Palatal Anesthesia Using Two Injection Techniques: An Study.

Background: Computer-controlled local anesthetic delivery (CCLAD) is an approach that uses a constant and slow flow of delivering the anesthetic solution into the tissues, which is capable of alleviating pain and discomfort in children.

Aim: Assessment of perceived pain in children during palatal anesthesia using Wand technique and conventional technique.

Materials And Methods: A total of 30 children requiring bilateral palatal anesthesia were included in the study in a split-half design.

To Evaluate the Marginal Adaptation of Porcelain Fused to Metal Crown with Different Base Metal Alloys.

Introduction: The success of any restoration depends on the marginal seal. The adaptation of castings, luting cement, and the surface structures of the margins are all important factors in achieving marginal seal.

Aim: The aim of this study was to evaluate the vertical marginal discrepancy of cast copings obtained by employing conventional casting technique with two different base metal alloys with two different finish lines before and after porcelain firing.
