Evaluation of marginal accuracy of polyetheretherketone and zirconia copings fabricated using computer-aided design/computer-aided manufacturing technique: An in vitro study.

Aim: The aim of this study was to compare the marginal accuracy of polyetheretherketone (PEEK) and zirconia copings fabricated using computer-aided design/computer-aided manufacturing (CAD/CAM) technology, and to assess the impact of their material properties on accuracy when produced with a 4-axis milling system under controlled conditions.

Settings And Design: The study employed an in vitro design with a stainless steel die model featuring a 6 mm axial wall height, a 6-degree total occlusal convergence, and a radial shoulder finish line.

Materials And Methods: Thirty stone dies were created from silicone impressions of the metal die and poured using type-IV dental stone.

To Develop and Implement a Preclinical Operative Dentistry Module to Enhance Class-II Cavity Preparation Training.

Background: A competent dental undergraduate at the preclinical level will ensure a confident transition into clinics and quality treatment for patients. Cavity preparation of a tooth is one of the key competencies in dentistry. A preclinical training module was introduced to enhance the skill training and improve students' learning.

Serum fatty acid profiles in systemic lupus erythematosus and patient reported outcomes: The Michigan Lupus Epidemiology & Surveillance (MILES) Program.

Introduction: Despite progress in systemic lupus erythematosus (SLE) treatment, challenges persist in medication adherence due to side effects and costs. Precision nutrition, particularly adjusting fatty acid intake, offers a cost-effective strategy for enhancing SLE management. Prior research, including our own, indicates that increased consumption of omega-3 polyunsaturated fatty acids (PUFAs) correlates with improved outcomes in SLE patients.

High altitude pulmonary oedema: Mimicker of acute coronary syndrome.

High altitude pulmonary oedema (HAPO) is a common emergency seen at high altitude. It can be associated with electrocardiogram (ECG) changes due to pulmonary arterial hypertension in the form of ST elevation and T wave inversion in the right precordial leads, which mimic acute coronary syndrome. These changes can lead to confusion in diagnosis and management.

Assessment of the effect of multi-walled carbon nanotubes (-OH functionalized) on growth characteristics and biochemical profile of Brassica juncea (L.) Czern. & Coss.

This study investigated the effect of various levels of OH-MWCNTs mediated seed priming on germination, growth, and biochemical responses of Indian mustard (Brassica juncea (L.) Czern. & Coss.
