Efficacy of laser photobiomodulation pulpotomy in human primary teeth: A randomized controlled trial.

Background: Laser photobiomodulation (LPBM), also called Low Level Laser Therapy (LLLT), has shown potential to reduce the pulpal inflammation and to preserve the dental pulp vitality, thereby improving healing. Lasers being minimally invasive, safe, and patient friendly prompt its application in pediatric dentistry.

Aim: The aim of this study was to evaluate and compare the clinical and radiographic success rates of LPBM and formocresol pulpotomy at 9 months post intervention in human primary molars.

Optimizing Kidney Replacement Therapy During the COVID-19 Pandemic Across a Complex Healthcare System.

The unprecedented surge of nephrology inpatients needing kidney replacement therapy placed hospital systems under extreme stress during the COVID-19 pandemic. In this article, we describe the formation of a cross campus "New-York Presbyterian COVID-19 Kidney Replacement Therapy Task Force" with intercampus physician, nursing, and supply chain representation. We describe several strategies including the development of novel dashboards to track supply/demand of resources, urgent start peritoneal dialysis, in-house preparation of kidney replacement fluid, the use of unconventional personnel resources to ensure the safe and continued provision of kidney replacement therapy in the face of the unanticipated surge.

Cone beam computed tomography aided endodontic and aesthetic management of fused mandibular incisors with communicating canals.

Endodontic treatment of fused teeth needs special care and attention due to its complex anatomy. The aim of this article is to highlight the problems encountered and the strategy in treating such cases. We report a case of unilateral fusion of the left mandibular central incisor and lateral incisor, with a single pulp chamber.

In Vitro Comparative Evaluation of Frictional Resistance of Connecticut New Arch Wires, Stainless Steel and Titanium Molybdenum Alloy Archwires Against Different Brackets.

Background and objectives Friction between the bracket and archwire during sliding mechanics is of great concern in orthodontics, as it reduces the effectiveness of the orthodontic appliance and slows down tooth movement. The aim of this study was to evaluate frictional resistance of stainless steel (SS), titanium molybdenum alloy (TMA), and Connecticut new arch (CNA) wires against SS and ceramic brackets. The surface textures of the brackets and wires were also evaluated by scanning electron microscopy (SEM) before and after testing.
