Evaluating the Aging of Stainless Steel Crowns: Volumetric and Morphological Insights from Nano-computed Tomography Imaging.

Introduction: Stainless steel crowns (SSCs) are commonly utilized in pediatric dentistry for restoring primary teeth affected by extensive decay or trauma, valued for their durability and cost-effectiveness. However, their performance may degrade over time due to wear, marginal discrepancies, and environmental factors, potentially leading to secondary caries and compromised retention. This study investigates the compressive strength, volumetric changes, morphological characteristics, and marginal integrity of SSCs extracted after 1 year and >3 years using nano-computed tomography (Nano-CT).

Comparative evaluation on wear resistance of metal sleeve, sleeve-free resin, and reinforced sleeve-free resin implant guide: An in vitro study.

Background: In-office three-dimensional (3D) printers and metal sleeveless surgical guides are becoming a major trend recently. However, metal sleeve-free designs are reported to be more prone to distortion which might lead to variation in the inner diameter of the drill hole and cause deviation and inaccuracy in the placement of the implant. Carbon fiber nanoparticles are reported to improve the properties of 3D printing resin material in industrial application.

The Role of Salivary Lactate Levels in assessing the Severity of Septic Shock.

Background: Sepsis is a major worldwide cause of morbidity and mortality. Hence, rapid and reliable diagnosis is essential. Emergency departments use a standard measure of sepsis, based upon an elevated Lactate level in blood.

Comparative Evaluation of Ion Release in Bonded and Nonbonded Stainless Steel Brackets with Use of Different Mouthwashes: An Study.

Background: Orthodontic treatment is a long-term procedure that involves the usage of brackets and archwires which are mainly metallic in nature. This study evaluated the levels of metal ions release from bonded and nonbonded orthodontic brackets after immersion in distilled deionized water and three different types of mouthwash.

Materials And Methods: Eighty premolar stainless steel brackets (3M, Unitek) were divided into Group A (bonded brackets) and Group B (nonbonded brackets).
