Lithium Disilicate Ceramics Pretreated With Ti: Sapphire fs, Er; Cr: YSGG, and Er: YAG Lasers: A Study on Mechanical Properties, Energy Dispersive Spectroscopy, Color Alterations, and Surface Topography.

To assess the efficiency of Er; Cr: YSGG laser (ECL), Er: YAG laser (EYL), and the Ti: sapphire femtosecond laser (TsFL) in terms of color change (ΔE) measured by a spectrophotometer, surface topography observed through SEM, surface roughness (Ra), and bond strength of Lithium disilicate glass-ceramic (LDC) to resin cement. A total of 84 LDC disks were manufactured and assigned randomly into four groups. Group 1-HFA treated, Group 2 treated with TsFL, Group 3 with EYL, and Group 4 with ECL.

Biogenic silver nanoparticle synthesis using orange peel extract and its multifaceted biomedical application.

The aim of this study was to employ an agro-industrial byproduct, specifically Citrus sinensis peels, as a reservoir of polyphenols. The natural chemicals present in C. sinensis peels serve as reducing agents in an environmentally benign method for synthesizing silver nanoparticles (AgNPs).

Dimensional stability of 3D-printed edentulous and fully dentate hollowed maxillary models over periods of time.

Background: Dental casts made utilising digital workflow are becoming more common because to their speed and cost savings. However, studies on their dimensional accuracy over time with diverse designs are missing.

Objective: The aim of this in vitro study was to assess the dimensional stability of 3D-printed edentulous and fully dentate hollowed maxillary models with 50-micrometer resolution over 1 day, 14 days, and 28 days using surface matching software.

Laparo-Endoscopic Single-Site Left Donor Nephrectomy In Patients With Uncommon Renal Vascular Anatomy: Does the Technique Make a Difference?

Background: To compare donor and recipient outcomes in patients with renal artery and ante-aortic renal vein vs unusual renal vascular anatomy undergoing laparoendoscopic single-site donor nephrectomy (LESSDN).

Methods: A retrospective chart review of the comparative study of donor and recipient outcomes of LESSDN in donors with venous abnormality (n = 28, group A), arterial abnormality (n = 74, group B), and standard donors (n = 248, group C).

Results: From September 2016 to August 2022, 350 left LESSDN were performed.
